Injection protocol generation device, injection apparatus and imaging system including generation device, injection protocol generation method and injection protocol generation program

Abstract

When imaging an imaging subject, a pixel value is maintained in a state of small fluctuation of the pixel value over an entire expected duration. A generation device includes: an imaging information acquiring unit acquiring information of an imaging site of an imaging subject; a subject information acquiring unit acquiring information of the imaging subject; and a protocol generation unit generating an injection protocol for a contrast medium based on the information of the imaging site and the information of the imaging subject, wherein the protocol generation unit generates the injection protocol including a first phase in which an injection rate decreases with a first acceleration, and a second phase which follows the first phase and in which the injection rate decreases with a second acceleration, and the injection rate at a start of the second phase is higher than the injection rate at an end of the first phase.
