The printer is used to print a hard copy of the ultrasound image. The hard copy can be used for examination by another doctor or saved in a patient’s file for use later. Hard copies of images are also given to expecting parents as a picture of their child.

Besides these applications, ultrasound is used to study a lot of other parts of the body. These include the carotid arteries, thyroid gland, blood cells, eyes, pancreas, spleen, liver, and gallbladder. In infants, ultrasound imaging can study the hips, brain, and spine.

I wonder if the M1x (or whatever they are called) will get the TB4 standard. That would require support for 2 4k display's per thunderbolt port, as well as a host of other intel specific features.

An ultrasound machine uses high-frequency sound waves, emitting these waves toward the body. These waves penetrate the skin and bounce off the inner organs and tissues.

The display or monitor shows the image of what the transducer is scanning. This allows the doctor to analyze the image before creating their diagnosis. It also enables the technician to navigate to the exact area that requires ultrasound imaging.

3D ultrasound imaging is often utilized to detect benign tumors and cancer in the early stages. Common areas for detection include the breasts, colon, prostate, and rectum.

Ultrasound scanning has evolved significantly over the past few decades. The machinery has been developed to become more compact, and the resulting imagery has become more detailed, high-quality, and vivid. Typical components of an ultrasound machine include:

A Computerized Tomography (CT) scan is another common medical imaging procedure used to identify ailments inside the body. However, this is quite different from ultrasound scan procedures.

It is a medical imaging method that uses sound waves on a body’s internal organs for testing, diagnostic, or therapeutic reasons. The sound waves travel through the body and are converted into an ultrasound image showing the condition and boundaries of fluid and soft tissue and internal organs in the body. This allows medical staff to diagnose problems and decide on treatment programs.

The process of performing a typical ultrasound is simple. The patient lays on an examination table, usually facing upwards. The sonographer adjusts the table and the patient’s position based on the requirements of the particular ultrasound procedure.

The working principle behind an ultrasound machine is similar to that of SONAR systems used in military and naval applications. Even bats use this principle to hunt their prey without relying on their sight.

There are dozens of medical applications for ultrasound machines. Here is a list of various cases where the technology is used to examine the body:

@burdett Unfortunately this is a known limitation with all M1 Macs, with the exception of the Mac Mini that can also drive a monitor via it's built-in HDMI port.

Most monitors and docks use DisplayPort to handle their video feed, even if they are thunderbolt monitors or docks. DisplayPort uses MST for multiple Displays on one port (daisy chaining or dock). Some Monitors and Docks truly use thunderbolt for their display signal. Things like Apples Pro Display, LG's ultrafine displays, Belkin docks to name a few use thunderbolt to carry the display signal and not DisplayPort. Its more to do with the technology being used to deliver the display signal then the cable being used. If I am not mistaken even Apples HDMI adapter actually uses DisplayPort, DisplayPort is really the de facto display standard not thunderbolt. Apple just missed the memo while on the ThunderBolt band wagon like 10 years ago.

Keyboards are used during ultrasound scans to enter patient data. Entering patient data allows every image to be saved correctly in the patient file. Storing patients’ ultrasounds with their data helps maintain accurate patient records on any digital medium.

The frequency of ultrasound waves in medical applications is between 2 MHZ and 15 MHZ. The higher the frequency, the shorter the wavelength and the more attenuation. Therefore, reducing the frequency and absorption allows us to study body structures and other features.

A workaround is to have the 2nd external monitor driven using 3rd-party DisplayLink drivers: https://www.displaylink.com/downloads/macos

The intel Macs will support 1 display per thunderbolt port. Some shenanigans can be done to get more displays than that as Intel sets the limit not Apple.

The image created is called a sonograph, and the technician conducting the ultrasound examination is called a sonographer.

Many people hear the term ‘sonography’ and consider it the same as ultrasound. While the two are similar, there are differences that you should be aware of.

The transducer sends and receives the sound waves. If you have seen an ultrasound machine, the transducer is the small handheld probe that the technician uses. In early devices, sending and receiving these waves was done by two different units.

According to CalDigit (my preferred Mac dock) This is not a limitation of CalDigit’s Thunderbolt or USB-C docks, but of the Thunderbolt 3 ports on the new M1-based Macs.

An ultrasound exam has the ability to map internal tissues and organs in 3D, without necessitating probes and needles. This is why ultrasound machines are present in almost every medical environment.

Once the gel is applied, the sonographer moves the ultrasound probe around the area of interest. The patient might feel some pressure from the ultrasound probe.

If you have a clinic or a medical testing facility, getting a good ultrasound machine should be the first thing on your list. Browse through the range available at USC Ultrasound to get the best of these machines and other medical equipment you require.

Using medical ultrasound imaging allows doctors to diagnose problems with internal organs and sources of inflammation or pain in the body.

Sonography is the term used for the imaging application of ultrasound technology. When used for diagnostic purposes and generating a picture, the method is called sonography.

Not only that, but ultrasound imaging is the most common testing method used on pregnant women to monitor the growth of a fetus inside the body.

Prices of new ultrasound machines start at about $5000 for economical versions and go up to $100,000 and over for flagship models. General ultrasound machines are on the cheaper end, while specialty machines with probes fall on the higher end of the scale.

Since CT scans use X-rays, the procedure is radioactive and potentially harmful to some extent. However, ultrasound scans produce no ionizing radiation exposure since they use sound waves instead.

The Doppler effect is based on sound waves and their echo reflected from moving objects. When ultrasound machines incorporate this principle, the process becomes Doppler ultrasound.

When they bounce and reflect, the reflected waves are recorded by the machine. The patterns of these reflections are used to generate visualizations of the inner organs and tissues of the body.

Doppler ultrasound is generally restricted to moving particles. Therefore, it is applied for studying the blood flow through the heart and the blood vessels in the body.

You can find used and brand-new ultrasound machines at USC Ultrasound. The best part is that if you cannot make a big one-time investment, USC Ultrasound provides financing options.

@mschroder For Intel machines with TB3, they can drive 2 and sometimes 3 monitors natively.  This includes 2 via a single TB cable using a TB dock or using a USB-C cable with a USB-C dock meant for Apple computers (verified with an OWC USB-C Dock).  If the dock is meant for Windows machines, the manufacturer will tend to implement DisplayPort Multi-Stream Transport (MST).  MacOS does not support this mode of DisplayPort so these docks do not work with any Apple machine other than mirroring the displays.

Apart from the price, there are other factors to consider when choosing ultrasound equipment or machine. Some of the most important ones are size, type, portability and image quality.

What is an ultrasound machine, and how does it work? In this article, we will cover the basics of ultrasound technology, how it works, and the different types of ultrasound imaging devices available.

This imaging technique uses ultrasound waves, which are very high-frequency sound waves. These sound waves cannot be heard or differentiated by human ears.

Ultrasound imaging is a term that almost everyone has heard at one point or another. There are many reasons why diagnostic ultrasound is one of the most common testing processes done in the medical field.

CT scans utilize X-rays to generate a detailed image of the body’s internal organs. The X-ray tube rotates to capture images of different body sections and tissues.

Usually, an ultrasound exam requires minimal special preparation for better image quality and assessment. The doctor or sonographer will provide any preparation guidelines necessary beforehand, based on the area that requires the ultrasound scan.

As mentioned earlier, no ionizing radiation is used to create ultrasound images, so there is no threat of medical conditions caused due to radioactivity.

As we mentioned earlier, the ultrasound process can be diagnostic or therapeutic. When it is diagnostic, it is used as an imaging method. When it is therapeutic, no imaging is generated. Typical therapeutic applications involve delivering deep heat to soft tissue areas.

The first medical ultrasound machine was developed in Glasgow by obstetrician Ian Donald and an engineer, Tom Brown. It was first invented in 1956 and further improved till it was perfected around 1959.

There are very few medical procedures that come without side effects, risks, or any pain involved. Ultrasound imaging is one of these few.

The price of ultrasound machines depends on the type of machine you buy and whether you get it new or used. It might surprise you that many of the ultrasound machines you see in a doctor’s office and emergency rooms are refurbished.

It has baffled me this entire time that Apple refuses to support DisplayPort MST. Apple claims to fully support the DisplayPort standard but lacking MST alone proves this is a lie. I use a displaylink dock myself so the multi display thing is not an issue for me but it is really annoying that I need to install software and give it permissions every time I reimage my M1 test mac. On Windows you dont actually need the software either, I bet it uses MST by default lol.

Ultrasound scanning is so common that you will find a diagnostic ultrasound machine in every medical testing facility. However, while people know what an ultrasound examination is, not many have an in-depth understanding of how it works.

While the concept of ultrasound waves was established more than 100 years ago, the use of this science in medicine was adopted after the Second World War. Some of the most memorable dates in the evolution of ultrasound technology are:

Control knobs enable the technician to adjust the settings for ultrasound scans to get a clear picture on the display. Other functions include zooming the picture in and out.

In the early stages of its development, ultrasound technology was limited to creating blurry 2-dimensional images of the area of interest. However, with modern technology, the results that can now be obtained are fascinating.

USC Ultrasound is one of the most reliable suppliers of ultrasound machines and equipment. Many of the machines you see in high-end hospitals or small clinics are sourced from USC Ultrasound.

The Central Processing Unit is the brain behind an ultrasound machine. It coordinates the different signals emitted and received by the transducer, interpreting the electrical signals in the form of a visual image on the monitor.

There are more benefits to ultrasound imaging methods than any other medical imaging procedure. Some of the benefits of ultrasound exams are:

Um.... my M1 Mac Mini is driving 3 right now, albeit with the use of one of OWC's docking station (so therefore two total cables running to the mac itself). It's worth noting that, between the three displays, only one is TB3, too.

Now, you might be wondering how the waves penetrate some organs while reflecting off others. This phenomenon is decided by the wavelength/frequency of the sound wave used.

Three dimensional (3D) ultrasound imaging machine captures different 2D images of the area of interest by the movement of the probe. These images obtained by ultrasound transducers are then superimposed by specialized software built into the machine, forming a 3D model of the tissue.

Thunderbolt 3 requires 1x 4k display per port, but that is the minimum not maximum. Typically if you are using the Thunderbolt Display, each thunderbolt controller supports so many displays. In the case of the MBP13 2x thunderbolt model has 1 thunderbolt controller. The MBP16 has 2x thunderbolt controllers. The number of thunderbolt controllers really comes in to play with the 5k+ displays as apple is sharing both thunderbolt ports display bandwidth on a single controller to drive the display. If the resolution is low enough I could see a single port supporting 4 or more displays. 2x 4k displays seems totally within spec to me if the display technology being used is thunderbolt. Everything aside of macOS could do the same thing through DisplayPort.

I seem to remember that also Intel Macs can't drive two monitors via one USB-C cable, as it is really a restriction of the thunderbold port. But you can use a second USB-C (or thunderbold) port for a second screen.

Once the patient is in the correct position, the sonographer applies a water-based gel to the area that requires imaging. The gel reduces the air between the transducer and the skin, allowing for better image quality as the sound waves bounce back to the transducer.

3D imaging is also used to study fetal development and detect abnormalities in its growth, such as disproportionate limbs. It can even measure the blood flow in fetal blood vessels.

For this, I don't know what to say, except I've always been able to drive 2 4K displays with my 2019 13" MBP over a single TB cable to a TB dock.  It is specifically NOT DisplayLink and NOT MST.  I assume it is sending everything as Thunderbolt with 2 discrete DP streams encapsulated in it (as TB does), then via whatever chip is in the dock, it splits those streams out from the TB stream and pushes them to the displays properly.  They do show up as discrete displays.

Doctors commonly ask patients not to eat or drink anything 12 hours before the ultrasound scan. The doctor might also recommend drinking a few glasses of water and avoiding urinating before the ultrasound scan in order to analyze a full bladder.

You'll need a Displaylink-certified USB-to-HDMI adapter. I believe this Startech adapter will work, USB32HD4K USB to HDMI 4K adapter: https://www.startech.com/en-us/audio-video-products/usb32hd4k,   Also the Dell thunderbolt dock may have a Displaylink-certified output so may just need the DisplayLink drivers.  I need to test to verify both of these.

Ultrasound is one of the safest medical examination procedures. There are no known disadvantages or risks associated with this process.

Just the other day I was testing this myself. I had a DisplayLink USB-A to HDMI adapter, that I have had for years. I was able to use this plugged into a USB-C mini hub into one of the USB-C ports on my 13" MacBook Pro M1. In the other USB-C port I used an official apple USB-C to HDMI adaper. Both my HDMI monitors worked. The real trick is buying an adapter that requires DisplayLink, as they don't always state that when you buy them.
