INJECTION PROTOCOL GENERATION DEVICE, INJECTION DEVICE AND IMAGING SYSTEM WITH THE GENERATION DEVICE, INJECTION PROTOCOL GENERATION METHOD, AND INJECTION PROTOCOL GENERATION PROGRAM
PROBLEM TO BE SOLVED: To maintain a pixel value in a state where a fluctuation of the pixel value is small over the entire scheduled duration during imaging a subject.SOLUTION: A generation device 23 includes: an imaging information acquisition part 12 for acquiring information an imaging region of a subject； a subject information acquisition part 13 for acquiring information of the subject； and a protocol generation part 16 for generating an injection protocol of a contrast medium on the basis of the information of the imaging region and the information of the subject. The protocol generation part includes a first phase in which an injection speed drops at first acceleration, and a second phase which follows the first phase and in which an injection speed drops at second acceleration, and generates an injection protocol such that the injection speed during starting the second phase is higher than the injection speed during ending the first phaze.SELECTED DRAWING: Figure 3【課題】被写体を撮像する際に、予定される持続時間全体に渡って、画素値の変動が少ない状態で画素値を維持する。【解決手段】生成装置２３は、被写体の撮像部位の情報を取得する撮像情報取得部１２と、被写体の情報を取得する被写体情報取得部１３と、撮像部位の情報及び被写体の情報に基づいて、造影剤の注入プロトコルを生成するプロトコル生成部１６とを備え、プロトコル生成部は、第１加速度で注入速度が低下する第１フェーズと、第１フェーズに続くと共に、第２加速度で注入速度が低下する第２フェーズとを含むと共に、第２フェーズの開始時の注入速度が第１フェーズの終了時の注入速度よりも高いように、注入プロトコルを生成する。【選択図】図３
