1. An X-ray CT apparatus comprising:
an X-ray irradiator configured to emit X-rays;
an X-ray detector configured to detect the X-rays emitted from the X-ray irradiator and transmitted through a subject; and
a processor configured to perform tomographic image construction processing of constructing a tomographic image of the subject based on projection data acquired by irradiating the subject with the X-rays from a plurality of angles, and perform region-of-interest reconstruction processing of reconstructing the tomographic image of the subject in a region of interest by executing Hilbert transformation,
wherein the processor is configured to display, on a display device, the tomographic image, and perform processing of displaying a GUI, which is a graphical user interface for setting or adjusting a Hilbert transformation region on which processing by the Hilbert transformation is performed, in the region-of-interest reconstruction processing.
