C10306: X-Ray CT Apparatus and Myocardial Perfusion Image Generating System
Novelty:
The present invention relates to an X-ray CT (computed tomography) device and a myocardial perfusion image generating system for taking contrast CT images such as coronary arterial contrast CT images, myocardial contrast CT images, and so forth, by continuously injecting a contrast medium, and generating a myocardial perfusion image using the obtained contrast CT images.
Value Proposition:
With a myocardial contrast examination using an X-ray CT apparatus, a contrast medium is injected into a patient, and contrast CT images are collected. Also, a blood flow dynamic state (perfusion) examination of the myocardium and a perfusion examination are possible. However, it takes a long time for scanning of a myocardial perfusion image, and an examination method resulting in increase of X-ray dosages for the subject ray is hardly acceptable, and accordingly, long-period dynamic imaging using an X-ray CT apparatus has never come into practical use so far. The present invention provides an X-ray CT apparatus and myocardial perfusion system with the following advantages:
• Requires less contrast medium
• Reduces exposure to X-ray
• Reduces length of procedure
Technical Details:
Johns Hopkins researchers have developed an X-ray CT apparatus for blood-flow information. Normally, such perfusion imaging is not an isolated examination, but performed as part of a contrast examination. Accordingly, the present invention has been made in light of the conventional situations, and it is an object of the present invention to provide an X-ray CT apparatus and a myocardial perfusion image generating system for generating a myocardial perfusion image in a short period while reducing the amount of injection of a contrast medium as to a subject and dosage due to X-ray.
Looking for Partners:
To develop and commercialize the technology as an X-ray CT apparatus.
