With a total of 2 patents, his work has advanced the capabilities of CT scanners, enhancing their diagnostic potential.

Latest Patents

One of Changguo Ji's latest patents is a method for spectral CT local tomography. This innovative method involves performing reconstruction for a region of interest (ROI) within an object. The process includes designating the ROI within the scan field of view (FOV) of a combined third- and fourth-generation CT scanner. The CT scanner utilizes fixed photon-counting detectors (PCDs) and an X-ray source that rotates around the object in synchronization with a rotating detector. The method also determines an on/off timing schedule for each PCD based on the size and location of the designated ROI. This allows for the collection of data sets that are then used to perform reconstruction and obtain ROI spectral images.
