X-ray diagnostic system and X-ray diagnostic method

摘要

An X-ray diagnostic system according to an embodiment includes: an X-ray tube for radiating an X-ray to the subject on the basis of a tube current for taking a scanogram of a subject; an X-ray detector for detecting the X-ray radiated by the X-ray tube and transmitted through the subject; a data collector for collecting X-ray dose distribution data, which shows the dose distribution of the X-ray; an image processor for creating the scanogram from the X-ray dose distribution data; a genuine data generator for generating genuine data showing the dose distribution of the X-ray, from the scanogram; a threshold value setting section for setting a threshold value for the genuine data; and a tube current adjustor for adjusting a tube current for taking a tomographic image of the subject in accordance with a comparison between the X-ray dose in the genuine data and the threshold value.

1. An X-ray diagnostic system comprising:
a tube current setting section for setting a tube current for taking a scanogram of a subject; an X-ray tube for radiating an X-ray to the subject on the basis of the tube current for taking the scanogram, the tube current set by the tube current setting section; an X-ray detector for detecting the X-ray radiated by the X-ray tube and transmitted through the subject; a data collector for collecting X-ray dose distribution data, which shows the dose distribution of the X-ray detected by the X-ray detector; an image processor for creating the scanogram from the X-ray dose distribution data collected by the data collector; a genuine data generator for generating genuine data showing the dose distribution of the X-ray detected by the X-ray detector, from the scanogram created by the image processor, or from raw data produced in a process of creating the scanogram by the image processor; a threshold value setting section for setting a threshold value for the genuine data generated by the genuine data generator; and a tube current adjustor for adjusting a tube current for taking a tomographic image of the subject in accordance with a comparison between the X-ray dose in the genuine data generated by the genuine data generator and the threshold value set by the threshold value setting section.
