Application prospects of phased-array computed tomography in the diagnosis and treatment of digestive system diseases: A cross-sectional survey

Figure 1 Schematic diagram of the electronic control imaging system for phased-array computed tomography. The core technology of Phased-array computed tomography is based on the electronic rotation of a full-circle detector array and a distributed X-ray source array, drawing on the principles of phased-array technology. It employs X-ray electronic steering technology based on multi-source coordination, replacing the mechanical rotation of the X-ray tube and detector in spiral computed tomography with electronic control technology. Specifically, at different time points T1, T2, and T3, the X-ray tube, under electronic control, sequentially irradiates the human body, forming a static spiral continuous rotation scan. The spatial angular positions at which the X-ray tube sequentially irradiates change from R1→R2→R3→R4→R5.
