Abstract: The present invention aims to provide a control device that reduces load and can provide early detection of program tampering. A main storage unit 102 stores a main application 107 and illegal command information 108. The main application 107 is an extension program in which target commands, which are at least some of the commands included in a prescribed program, have been converted into extension commands. The illegal command information 108 indicates the target commands. A command monitoring unit 104: compares executed commands, which are commands that have been executed by the CPU 103, and target commands, which are indicated in the illegal command information 108; and determines whether or not an executed command is an illegal command, based on the comparison results.

Abstract: A region of interest setting unit sets a region of interest within image data for a tomographic image. The region of interest setting unit sets the region of interest to the heart of an embryo and partitions the region of interest into a plurality of blocks. A waveform generating unit generates an embryonic heartbeat waveform for each block of the plurality of blocks within the region of interest on the basis of the image data within the block. A waveform evaluating unit uses a standard waveform to evaluate the reliability of the embryonic heartbeat waveform for each block of the plurality of blocks within the region of interest.
