Optimized Camera-Based Patient Positioning in CT

Abstract: The aim of this study was to evaluate whether a 3-dimensional (3D) camera can outperform highly trained technicians in precision of patient positioning and whether this transforms into a reduction in patient exposure. Materials and Methods: In a single-center study, 3118 patients underwent computer tomography (CT) scans of the chest and/or abdomen on a latest generation single-source CT scanner supported with an automated patient positioning system by 3D camera. One thousand five hundred fifty-seven patients w… Show more

“…Automatic exposure control can increase the applied radiation exposure in off-centreed patients, due to the shape of the bowtie filter, if a real-time angular tube current modulation is available. Some vendors already offer camera systems that automatically position the patient inside the scanner gantry, based on the patient shape and contours using anatomical landmarks [11,17,18]. The optimal table height for the desired scan region is automatically calculated.…”

“…However, it is questionable how well this works on a day-to-day basis when patients (especially ICU patients) are placed on the bed with foreign material and blankets. In the study of Manava et al, patients were examined positioned using a camera system, however, only patients without blankets were included [17].…”

“…Optical and depth information are processed to automatically adjust the table height to match the isocenter of the patient with the isocenter of the scanner and to support the definition of the scan range. [30][31][32][33] Manava et al 31 analyzed data from 3118 patients who underwent CT of the chest and abdomen: 1575 patients were positioned laser-guided by a radiographer, 1561 patients with 3D camera guidance. Although the radiographers were highly trained, isocenter positioning was significantly improved with the 3D camera.…”
