Method and apparatus for cardiac radiological examination in coronary angiography

An apparatus comprising:

• means for providing a source of radiation to an anatomical structure;
• means for detecting the radiation alter pausing through the anatomical structure;
• means for providing an image of the anatomical structure after the radiation has passed through the anatomical structure;
• means for injection of a contrast medium with a pigtail catheter for cardiac radiology simultaneously in a left coronary and a right coronary from the root of an aorta;
• means for guiding the catheter by a signal detecting cardiac rhythms, so as to inject the contrast medium during cycles synchronized with given phases of the cardiac rhythm;
• means for acquiring a sequence of dynamic images of propagation of the contrast medium in the left and right coronary arteries with procession of an image plane, upon acquisition of the images, in a given path;
• and
• means for acquiring a new dynamic image sequence with the procession of the image plan, without introduction of contrast medium.

• means for acquiring a dynamic image sequence with procession of an image plane upon acquisition of the image sequence, on a given path before introducing the contrast medium in the left coronary artery and in the right coronary artery from the root of the aorta;
• means for acquiring a sequence of dynamic images of propagation of the contrast medium in the left and right coronary arteries with procession of an image plane, upon acquisition of the images, in a given path;
• and
• means for acquiring a new dynamic image sequence with the procession of the image plane, after introducing the contrast medium and without addition of the contrast medium.
