2. Description of the Related Art For example, in an angiography test (angiography test) using a CT device (computer tomography device), a catheter is passed through an artery at a target site such as a hepatic artery, and a contrast agent is rapidly injected into the artery. This is to take a tomographic image of the target part. Since this test involves insertion of a catheter into the patient's artery, the test environment must be kept clean to prevent the transmission of pathogens into the patient from the point where the catheter is placed.

[0003]

However, in the above-described angiography, bleeding may occur when the catheter is inserted and placed in the artery of the patient. Also, during the inspection,
The contrast medium must be continuously injected into the artery, and blood and the contrast medium containing blood may leak from the place where the catheter is placed in the artery. As described above, blood leaking from the place where the catheter is placed in the artery and the contrast medium containing blood may adhere to the inner wall surface of the gantry of the tomography diagnostic apparatus and its surroundings, and this may cause an unsanitary examination environment. It was a factor to be assumed.

[0004] That is, in the gantry of the tomography diagnostic apparatus, an opening is formed in which a patient placed on an imaging table is slid and scanned with X-rays or the like to take a tomographic image of the patient. When blood enters and exits, blood or a contrast agent containing blood may adhere to the inner wall surface and its surroundings. When blood or a contrast medium containing blood adheres to the gantry of the tomography diagnostic apparatus, it is necessary to completely wipe off the blood or the contrast medium containing blood each time the examination is completed, and to disinfect that part.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cover for a tomographic diagnostic apparatus which can prevent contamination of a gantry of the tomographic diagnostic apparatus and keep the inspection environment clean.
