Fluoroscopy operator protection device
A radiation protection device attaches to the C-arm of a fluoroscope and shields and collimates the X-ray beam between the X-ray source and the patient and between the patient and the image intensifier. One embodiment has a radiation shield of X-ray opaque material that surrounds the C-arm of the fluoroscopy system, the X-ray source and the image intensifier. A padded slot fits around the patient's body. Another embodiment has conical or cylindrical radiation shields that extend between the X-ray source and the patient and between the patient and the image intensifier. The radiation shields have length adjustments and padded ends to fit the device to the patient. The radiation protection device may be motorized to advance and withdraw the radiation shields. A blanket-like radiation shield covers the patient in the area surrounding where the X-ray beam enters the body.
1. A method for performing fluoroscopy with radiation protection, said method comprising:
providing an X-ray source and an X-ray detector/image intensifier mounted on a C-arm adjacent a procedure table;
positioning a first end of a first radiation shield around the X-ray source and extending a second end of the first radiation shield to contact the procedure table or a body of a patient on the procedure table;
positioning a first end of a second radiation shield around the X-ray detector/image intensifier and extending a second end of the second radiation shield to contact the procedure table or the body of the patient on the procedure table; and
directing x-rays from the x-ray source through the body of the patient to the X-ray detector/image intensifier while the patient lies on the procedure table within the C-arm, wherein the first radiation shield and the second radiation shield block stray radiation being emitted beyond the body of the patient.
2. The method of claim 1 , further comprising retracting the second end of the first radiation shield and the second end of the second radiation shield away from contact with the procedure table or the body of the patient after completion of a fluoroscopic procedure.
3. The method of claim 1 , wherein extending a second end of the first radiation shield to contact the procedure table or the body of the patient comprises contacting a first soft, conformable edge surrounding the second end of the first radiation shield against the body of the patient or the table.
4. The method of claim 3 , wherein extending a second end of the second radiation shield to contact the procedure table or the body of the patient comprises contacting a second soft, conformable edge surrounding the second end of the second radiation shield against the body of the patient or the table.
5. The method of claim 1 , further comprising adjusting a length of the first radiation shield and a length of the second radiation shield to accommodate motion of the C-arm relative to the patient.
6. The method of claim 5 , wherein the first radiation shield and the second radiation shield are spring biased to maintain their second ends in contact with the procedure table or the body of the patient on the procedure table to accommodate motion of the C-arm relative to the patient.
7. The method of claim 5 , further comprising sensing proximity or initial contact of the second end of the first radiation shield with the procedure table or the body of the patient to control adjusting the length of the first radiation shield.
8. The method of claim 7 , further comprising sensing proximity or initial contact of the second end of the second radiation shield with the procedure table or the body of the patient to control adjusting the length of the second radiation shield.
