![]() NNPS of the AIRO shows low frequency noise due to ring-like artifacts which may be caused by detector calibration or lack of artifact reducing image post-processing. The Standard kernel in the AIRO system was evaluated to have 3 lp/cm and 4 lp/cm for the body and head FOVs respectively. The Siemens scanner had up to 7 lp/cm for the head FOV and H40 kernel and up to 5 lp/cm at body FOV for the B40f kernel. Based on MTF analysis, both Soft and Standard filters of the AIRO system lost resolution quickly compared to the Sensation 64 slice CT. Under identical technique factors radiation dose (mGy/mAs) from the AIRO mobile CT system (AIRO) is higher than that from a 64 slice CT scanner. Radiation dose and image quality were compared to those from a multi-detector CT scanner (Siemens Sensation 64). Spatial resolution, low contrast resolution, Modulation Transfer Function (MTF), and Normalized Noise Power Spectrum (NNPS) were analyzed. Image quality was evaluated with a CATPHAN 500 phantom. Radiation dose was measured using a conventional 100 mm pencil ionization chamber and CT polymethylmetacrylate (PMMA) body and head phantoms. “CT systems must be designed and validated for safety and efficacy using different protocols than would be appropriate for adult patients.Radiation dose and image quality from a recently introduced mobile CT imaging system are presented. There is an unmet need in being able to provide safe and reliable CT imaging for pediatric patients during various clinical procedures,” said Gene Gregerson, CEO of Mobius Imaging. “We are delighted to now be able to offer the benefits of Airo Mobile CT imaging to clinicians and their pediatric patients. The user-friendly control software allows even one person to easily move the system among ORs, with a front-view safety camera to ensure stress-free portability and safe passage through standard doors and elevators. ![]() The suspension-controlled Airo Mobile CT is electrically driven, with a single central wheel for compact maneuvering. Fully adaptable, the Airo TruCT can move into a variety of procedural setups for cranial, spine, and trauma cases.Ī compact, detachable touch-screen pendant controls all imaging setups, including laser alignment and dose display, while a simple, handheld system controller commands system transport, daily calibration, and system maintenance. The gantry is fully integrated into the TRUMPF Medical TruSystem 7500 surgical table, which permits a fixed correlation between the patient and the scanner, resulting in reliable, reproducible, imaging. ![]() The gantry houses custom components including an X-Ray tube, a 32-slice helical scan detector array, a high-voltage generator, an air-cooling system and a built-in battery pack. Indications include cranial, spine, trauma, and pediatric procedures. The innovative design provides a scan volume of 50 cm diameter x 100 cm length, allowing surgeons to image the entire spine in a single scan and to visualize more anatomical context than traditional C-arms. The Mobius Imaging (Shirley, MA, USA) Airo Mobile TruCT Imaging System is designed for diagnostic and intraoperative procedures inside existing operating room (OR) suites by combining an extra-large bore size, an extra-small footprint, and an extra-slim patented gantry design. A mobile computerized tomography (CD) system provides high quality intraoperative images, increasing surgeon confidence and supporting advanced minimally invasive surgery (MIS).
