Dynamic radiographing system

摘要

A dynamic radiographing system enables determination of an evaluation value of the heart function of a subject by plain radiography. The dynamic radiographing system comprises a radiographing apparatus, an image processing apparatus, and a console for diagnosis. The radiographing apparatus dynamically radiographs the heart of a subject and creates radiographs in plural time phases (Step S1). The image processing apparatus calculates an evaluation value of the heart function by using the radiographs in plural time phases (Step S4). The console for diagnosis displays information on the calculated evaluation value on the display section (Step S5).

主权项

1. A dynamic radiographing system comprising:
a radiographing device which radiographs dynamically a part of a subject by plain radiography and generates X-ray images in a plurality of time phases, the radiographing device including
an X-ray source for emitting an X-ray anda detector for detecting the X-ray emitted from the X-ray source; and an image analysis device for analyzing images by using the X-ray images in the plurality of time phases; wherein the radiographing device radiographs the part of the subject over a plurality of cycles of the part, each of the cycles comprising the plurality of time phases, and the image analysis device is structured to display an evaluation value about a function of the part of the subject based on a change in signal values in the X-ray images over the plurality of cycles of the part of the subject.
