![]() ![]() IM-SHORAD is installed on General Dynamics’ Stryker A1 8×8 wheeled armoured vehicle that is outfitted with a 450hp Caterpillar C9 engine and a 60,000lb suspension system. The IM-SHORAD capability is interoperable with Sentinel radar and can be integrated with the existing US Army networks. The US Army intends to procure up to 144 IM-SHORAD air defence systems, which will be deployed to perform combat operations in Europe. The remaining four systems are expected to be delivered in November 2020.ĭevelopmental testing is currently underway, while the operational testing is expected to begin in September 2020. The first prototype was handed over to the US Army in October 2019 and four more systems were delivered by March 2020. The US Army placed an order for a total of nine IM-SHORAD prototypes in September 2018. The US Army obtained a directed requirement to build an IM-SHORAD system in February 2018 to provide direct fire support for its Stryker and Brigade Combat Teams (BCT) against aerial threats. General Dynamics serves as the platform integrator for the IM-SHORAD air defence vehicle, while Leonardo DRS was selected to provide mission equipment package for the IM-SHORAD system. on behalf of American Association of Physicists in Medicine.IM-SHORAD will also offer protection against artillery, rockets and mortars as well as regional ballistic missile threats such as Patriot and the Terminal High Altitude Area Defence (THAAD) system. ![]() Journal of Applied Clinical Medical Physics published by Wiley Periodicals, Inc. Based on our study, the Mobile AIRO CT system can be utilized accurately and reliably for image-guided proton therapy. The localization accuracy of AIRO was determined to be within 0.6° and 0.5 mm despite its slightly lower image quality overall compared to other CT imaging systems at our institution. Localization accuracy (based on Stereophan) demonstrated maximum AIRO-kV/kV shift differences of 0.1 mm in the x-direction, 0.1 mm in the y-direction, and 0.2 mm in the z-direction. Localization accuracy (based on the MIMI phantom) was 0.6° and 0.5 mm. The AIRO exhibited higher dose (>27 mGy) than the Philips CT Simulator. AIRO/Siemens and AIRO/Philips differences exceeded 100% for scaling discrepancy (191.2% and 145.8%). The AIRO spatial resolution was 0.21 lp mm -1 compared with 0.40 lp mm -1 for the Philips CT Simulator, 0.37 lp mm -1 for the Edge CBCT, and 0.35 lp mm -1 for the Siemens CT Simulator. For treatment delivery systems (Edge and Mevion), the localization accuracy of the 3D imaging systems were compared to 2D imaging systems on each system. Localization accuracy and CT Dose Index were measured and compared to reported values on each imaging device. Low CNR was acquired manually using the CTP515 module. Modulation transfer function, scaling discrepancy, geometric distortion, spatial resolution, overall uniformity, minimum uniformity, contrast, high CNR, and maximum HU deviation were acquired. DoseLAB software v.6.6 was utilized for image quality analysis. This is the first known application of the AIRO for proton therapy.įive CT images of a Catphan ® 504 phantom were acquired on the AIRO Mobile CT System, Varian EDGE radiosurgery system cone beam CT (CBCT), Philips Brilliance Big Bore 16 slice CT simulator, and Siemens SOMATOM Definition AS 20 slice CT simulator. The purpose of this study was to characterize the Mobius AIRO Mobile CT System for localization and image-guided proton therapy. ![]()
