Cardiovascular x-ray diagnostic system

Abstract

A cardiovascular x-ray diagnostic system capable of taking radiographs at different positions by moving at least one of a tabletop on which a subject is placed and a radiographic system equipped with an x-ray tube and an x-ray detector includes: an acquisition unit configured to acquire a radiography position from a position of the tabletop and a position of the radiographic system; a reference position identification unit configured to identify a reference radiography position; and a radiographic unit configured to take radiographs by changing a radiographic parameter based on a current radiography position acquired by the acquisition unit and the reference radiography position.

Description

technical field [0001] The present invention relates to an X-ray diagnostic system for a circulator that sequentially selects and sets an optimal imaging program or imaging condition parameter according to an imaging site when imaging is performed while moving a target site. Background technique [0002] In recent years, X-ray diagnostic systems for circulators have been used as devices that support not only routine examinations for existing diagnoses but also treatment (IVR: Interventional Radiology) using catheters in real time. In catheter-based treatment (IVR) and examination for coronary artery stenosis, angiographic confirmation of lower extremity arteries is sometimes performed after a series of coronary angiography and treatment due to the risk of concurrent lower extremity arterial stenosis. In this imaging, since it is desired to perform imaging over a wide range as much as possible by injecting a contrast agent in order to reduce the amount of contrast agent, a me...

Problems solved by technology

However, the operator sometimes forgets to switch the imaging program or imaging condition parameters before performing sliding DA imaging of the lower limbs, and in this case, there is a problem that appropriate imaging images may not be collected.
