Abstract: A second detection unit detects a second gesture for switching between a rough adjustment mode in which the range of settable numerical values for a slide bar is a first range or/and the unit change width for a numerical value is a first change width and a fine adjustment mode in which the range is a second range narrower than the first range or/and the unit change width is a second change width narrower than the first change width. A mode switching unit switches between the rough adjustment mode and the fine adjustment mode in accordance with the second gesture. A display control unit causes a rough adjustment slide bar and a fine adjustment slide bar to be selectively displayed on an HMD.

Abstract: It is detected whether a grid stripe is present in a radiographic image. In a case in which the grid stripe is detected, a process of removing the grid stripe from the radiographic image is performed and the radiographic image is displayed. In a case in which the grid stripe is not detected, a process of removing a scattered component from the radiographic image is performed and a radiographic image subjected to the scattered radiation removal process and a radiographic image before the process are displayed.

Abstract: An ultrasound diagnostic apparatus performs transmission and reception of ultrasonic waves for forming focal points used to set sound velocities at predetermined timing such that sound velocities having been set for all of respective segment regions established by diving a subject are all reset every predetermined number of frames. Owing to this configuration, it becomes possible for the ultrasound diagnostic apparatus to suitably reset sound velocities of ultrasonic waves in the subject and also reduce the amount of calculation for resetting sound velocities.
