Abstract: X-ray imaging represents the most commonly used imaging modality in X-ray-guided vascular intervention procedures. Computed tomography (CT) data ensure that the procedure is performed accurately and safely by providing medical staff with positional information of the body part before starting the procedure. In particular, accurate geometric information of the imaging equipment is essential to accurately calculate the three-dimensional (3D) position of catheters used in delicate operations. However, it is difficult to gather this information before surgery. Therefore, this study proposes a novel calibration method that can be used immediately before a procedure and can guarantee the stability of the procedure. The calibration was performed without additional radiography using sinogram data obtained during the 3D CT imaging process, and both the accuracy and calculation time available in the vascular intervention theater were allowable. The experimental results show that the best angular conditions in terms of calculations and accuracy are between −40 and 40 degrees in angular range and 1.6 degrees in angular interval. Consequently, we achieved a calculation time of 2.92 s and an average accuracy of 0.36 mm, thus meeting our goal of accuracy below 1 mm within a minute of computational time.

Our Extreme G-Trac Brace mounts close to the control arm mounts, and helps strengthen the connection between the control arm mounts, and the rear of the sub frame. This makes the load path more direct, and gives much more effective stiffening, so the suspension geometry doesn’t change during high cornering/chassis loads. Manufactured from super strong chrome moly, alloy steel tube, making it over twice as strong as any mild steel offering. Note: Includes G-Trac Brace and installation hardware. Product Benefits Improves suspension compliance Also referred to as k-member brace Stiffens front sub-frame Bolt-on installation Clears long tube headers! Fitment : S550 Mustang (2015+)  All models, Automatic + manual NOTE: This brace does NOT fit 2018 Ecoboost with A10 auto trans or Mach ONE / GT350. Mach One/ GT350 owners should purchase 555-5533 instead.

Outstanding from start to finish! Ben and the team are so helpful, they offer the best advice, not profit-driven advice, which is refreshing. The exhaust upgrade is beyond what I expected. Thanks, Ben & the team. See you soon for the pulley change and tune!!!

Our Extreme G-Trac Brace (k-member brace) is a direct bolt-on addition to your S550 Mustang and provides greatly improved front chassis bracing for improved steering feel and handling control. Homologated / Certified for European use. For GT and Ecoboost models from 2015 onwards.

Had my car at MAP again, as normal what brilliant service you get..! I couldn’t praise or recommend them enough. It’s so nice to be able to call a company up, and they know what they are doing. The people working there are true professionals, from a service to fault finding to mods. I wouldn’t go anywhere.

Visited MAP today. Friendly, welcoming, very knowledgeable guys and got exactly what I asked for with a few tweaks from their recommendations. Couldn't fault the place and a very impressive dyno setup. Will definitely be back.

MAP have done a full remit of work on my car, and everything was mega professional to say I'm happy with the car now would be dumbing it down. I'm over the moon with it, it's the first time getting in the car after their work, and it's a total game changer drives exactly as it should do and how I wanted it to.
