Periodic displacement occurs in body tissue due to heartbeat. A peak level D of the movement distance of the body tissue is detected (Step), and a heartbeat cycle T is calculated from a frequency spectrum (Stepsand). By dividing twice the peak level D by the heartbeat cycle T, the moving velocity of the body tissue in a unit heartbeat cycle is calculated (Step). By dividing the moving velocity by a frame rate r, an average movement distance of the body tissue between frames is calculated (Step). In a case where the average movement distance is smaller than a predetermined threshold value, a time interval between the frames used for the calculation of the movement distance is extended (being StepNO, Step).

Photoacoustic image evaluation apparatus, method, and program, and photoacoustic image generation apparatus

An ultrasound imaging system includes a processor that is programmed to operate the system in a normal operating state and two or more lesser power states. The processor lowers the operating power state to a lesser power state upon detecting one or more operating conditions such as no tissue been imaged in a predetermined time limit or that the imaging system or transducer has not been moved in a time limit. Upon awakening from a power off state, the processor implements a lesser power state before operating at the normal operating state to avoid undue power use until the transducer is positioned to image tissue.
