Abstract:
A dynamic image processing apparatus includes a hardware processor that detects an abnormal site of an imaging object from a radiographically taken dynamic image, and identifies a three-dimensional position of the abnormal site from a positional relationship between the abnormal site of the imaging object detected from one dynamic image and the abnormal site of the imaging object detected from another dynamic image when the abnormal site is detected from a plurality of dynamic images radiographically taken in a plurality of directions.
Abstract:
A dynamic analysis system includes a hardware processor and an output device. The hardware processor obtains a cycle of temporal change in a feature amount relevant to a function to be diagnosed from each of dynamic images obtained by imaging of a dynamic state of a living body with radiation. The hardware processor further adjusts the obtained cycle, thereby generating a plurality of cycle-adjusted data having cycles of the temporal change in the feature amount being equal to one another. The hardware processor further generates difference information at each phase in the plurality of cycle-adjusted data. The output device outputs the difference information.
Abstract:
A non-transitory computer-readable storage medium stores a program that causes a computer to perform an obtaining process, an analyzing process, and an extracting process. In the obtaining process, the computer obtains a radiographic moving image showing a motion of a specific part of an examinee. In the analyzing process, the computer analyzes the radiographic moving image obtained in the obtaining process. In the extracting process, the computer extracts, among frames constituting the radiographic moving image, a specific frame that visibly shows a detection target in the specific part, based on a result of analyzing a dynamic state of the specific part in the analyzing process.
