![]() The entire base is positioned headfirst through the AIRO scanner and then secured to the AIRO base. After induction patient positioned prone onto the AIRO table, which will be on a wheeled base. on behalf of American Association of Physicists in Medicine. Airo is the new mobile CT scanner which functions seamlessly with Brainlab navigation systems to provide high-resolution diagnostic-quality images intraoperatively. +/- Airo CT: Airo positioned at the head of the bed. 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 Mobile CT integrates advanced imaging technologies into existing medical workflow and provides the clinician with procedural flexibility as well as real-time CT imaging information. 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. Brainlab) was used, closely integrated in the navigation setup consisting of a ceiling-mounted double. ![]() 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. For iCT scanning a 32-slice movable CT scanner (AIRO. The purpose of this study was to characterize the Mobius AIRO Mobile CT System for localization and image-guided proton therapy. ![]()
