During these procedures, the operators are exposed to a variable dose of radiation. It is shown that these professionals are among the most exposed to ionizing radiations. New studies have shown that brain cancers can be linked to these exposures. As these exposures are harmful to health, maximum protection is required to protect the patient and the staff. The current invention provides an improved protective shield to fully protect the staff in cardiologic, angiologic, and radiologic procedures. The present invention relates to a modified surgical drape that include a layer that absorbs the X-rays scattered from the patient's body during invasive angiology procedures. ## Claims ### Claim 1 A method for shielding an operator from radiation during a coronary intervention procedure of a patient with X-ray imaging comprising spreading a sterile surgical drape over the patient to provide shielding, wherein the sterile surgical drape comprises an integrated radio-protective layer that does not move independently from the sterile surgical drape and that does not lie in the path of the primary X-ray beam during the coronary intervention procedure, wherein the sterile surgical drape is at least 130 cm in width and at least 130 cm in length, wherein the integrated radio-protective layer is at least 130 cm in width, and wherein the integrated radio-protective layer is at least 60 cm in length, wherein the integrated radio-protective layer comprises at least one precut hole that can be opened to allow access to the patient; and performing the coronary intervention procedure with X-ray imaging, wherein the sterile surgical drape reduces the cumulative dose of the operator of the coronary intervention procedure to 0-5 μSv when accessed through the right radial artery. ### Claim 2 (depends on 1) The method of claim 1, wherein the integrated radio-protective layer has at least two precut holes that can be opened to allow access to the patient. ### Claim 3 (depends on 2) The method of claim 2, wherein the integrated radio-protective layer comprises at least two precut holes of at least 5 cm in diameter and separated by between 90 cm and 110 cm. ### Claim 4 (depends on 2) The method of claim 2, wherein the integrated radio-protective layer comprises at least two precut holes of at least 5 cm in diameter and separated by between 20 cm and 50 cm. ### Claim 5 (depends on 2) The method of claim 2, wherein the integrated radio-protective layer comprises at least two precut holes of at least 5 cm in diameter and separated by between 50 cm and 90 cm. ### Claim 6 (depends on 2) The method of claim 2, wherein the integrated radio-protective layer comprises at least two precut holes of at least 5 cm in diameter and separated by between 90 cm and 110 cm and at least two additional precut holes of at least 5 cm in diameter and separated by between 20 cm and 50 cm. ### Claim 7 (depends on 2) The method of claim 2, wherein the precut holes are between 5 cm and 15 cm in diameter. ### Claim 8 (depends on 2) The method of claim 2, further comprising at least two rectangular extensions of the precut holes of at least 5 cm by 10 cm. ### Claim 9 (depends on 1) The method of claim 1, wherein the integrated radio-protective layer comprises a hole of at least 30 cm×30 cm for passage of the primary X-ray beam. ### Claim 10 (depends on 9) The method of claim 9, wherein the hole is between 30 cm×30 cm and 40 cm×50 cm. ### Claim 11 (depends on 1) The method of claim 1, wherein the surgical drape is at least 190 cm in length. ### Claim 12 (depends on 11) The method of claim 11, wherein the surgical drape is at least 250 cm in length. ### Claim 13 (depends on 12) The method of claim 12, wherein the surgical drape is at least 200 cm in width. ### Claim 14 (depends on 1) The method of claim 1, wherein the integrated radio-protective layer has at least 0.25 mm lead equivalence at 70 kVp. ### Claim 15 (depends on 1) The method of claim 1, wherein the sterile surgical drape reduces the cumulative dose of the operator of the coronary intervention procedure accessed through the right radial artery to 0-4 μSv. ### Claim 16 (depends on 1) The method of claim 1, wherein the sterile surgical drape reduces the cumulative dose of the operator of the coronary intervention procedure accessed through the right radial artery to less than 5 μSv. ### Claim 17 (depends on 1) The method of claim 1, wherein the sterile surgical drape reduces the cumulative dose of the operator of the coronary intervention procedure accessed through the right radial artery to 0-2 μSv. ### Claim 18 (depends on 1) The method of claim 1, wherein the sterile surgical drape reduces the cumulative dose of the operator of the coronary intervention procedure accessed through the right radial artery such that no cumulative dose of the operator is detected. ### Claim 19 (depends on 1) The method of claim 1, wherein the sterile surgical drape reduces the cumulative dose of an assistant of the coronary intervention procedure accessed through the right radial artery such that no cumulative dose of the assistant is detected.
