    • An X-ray CT apparatus 1 for radiating X-ray to a subject P so as to scan the subject P and reconstructing a image within the subject P based on an obtained projection data comprises an image generating unit and a blood-flow image generating unit 24e. The image generating unit generates the image based on the projection data in a state in which a concentration of a contrast medium in a myocardial portion of a subject P continuously injected the contrast medium can be considered to be constant. The blood-flow image generating unit 24e generates a blood flow image by removing components of a myocardial tissue from a portion of a myocardial region of the image generated by the image generating unit.
    • 用于基于获得的投影数据向对象P照射X射线以扫描被摄体P并重建被摄体P内的图像的X射线CT装置1包括图像生成单元和血流图像生成单元 24 e。 图像生成单元在连续注入造影剂的被检体P的心肌部分中的造影剂的浓度可以被认为是恒定的状态下,基于投影数据生成图像。 血流图像生成单元24e从图像生成单元生成的图像的心肌区域的一部分中除去心肌组织的成分,生成血流图像。

    • A semiconductor circuit device, in which an output device is driven by inputting a direct current voltage source having a predetermined potential difference on the high potential side relative to a system ground and a power supply having a potential varied with time relative to the system ground. The semiconductor circuit device includes a voltage conversion circuit which converts an input signal having an amplitude between the system ground and the direct current voltage source into a converted signal having an amplitude between an internal ground and an internal power supply, and outputs the converted signal. The internal ground is controlled to have a potential varied with time relative to the system ground, and the internal power supply is controlled to change according to a change of the internal ground and have the predetermined potential difference on the high potential side when the internal ground has a fixed potential. A selector circuit selects and outputs the input signal and the converted signal according to the potential of the internal ground.
