Definitions
- the present invention relates to radiation protection devices to protect fluoroscopy operators and other medical personnel from radiation exposure during fluoroscopic imaging procedures.
- Fluoroscopy a real-time X-ray imaging technique, has long been important as a medical diagnostic tool, particularly in disciplines where still X-rays do not provide sufficient diagnostic information of the movement and function of living, moving organs. Fluoroscopy is widely used in cardiology, electrophysiology, gastroenterology and orthopedics. With the recent growth in catheter-based interventional cardiology and radiology procedures, there has been a tremendous increase in the use of fluoroscopy. Many life saving interventional procedures would not be possible without the use of fluoroscopy. However, fluoroscopic imaging exposes the patient and attendant medical personnel to potentially harmful X-ray radiation. For the patient, some exposure to X-rays is necessary to produce the fluoroscopic images and the exposure is usually brief and infrequent.
- X-ray exposure to medical personnel comes from two sources, direct exposure to the X-ray beam and scattered X-rays. Direct exposure occurs when the operator's hands or other body parts are placed in the X-ray beam while the fluoroscope is operating.
- X-ray scattering occurs when X- rays strike electrons in the patient's tissue and are deflected back and to the sides at angles that are not parallel to the incident beam. While scattered X-rays are much lower intensity than the direct X-ray beam, it is much more likely for the operator to be exposed to scattered X-rays and the damaging effects are cumulative from months and years of exposure.
- a radiation protection device that provides more complete protection and that reduces or eliminates the necessity for using heavy radiation protection garments.
- Such a device would ideally protect the fluoroscope operator and all nearby personnel from direct exposure to the X-ray beam and from scattered X-rays.
- the device should not interfere with the performance of the fluoroscopy or any diagnostic or therapeutic procedures performed during fluoroscopy.
- the device would be free of other inconveniences to the operator or the patient.
- a truly effective radiation protection device could reduce the overall cost of radiation protection by eliminating the need for lead aprons and other protective gear and could even simplify the construction of the fluoroscopy suite in the hospital by decreasing the amount of radiation shielding necessary.
- the present invention provides a radiation protection device with one or more radiation shields that attach to the C-arm of the fluoroscopy system and shields and collimates the X-ray beam between the X-ray source and the patient and between the patient and the image intensifier. This will protect the operator from inadvertently being exposed to the direct X-ray beam and will eliminate a significant percentage of the scattered X-rays.
- the radiation protection device may also include a blanket-like radiation shield that covers the patient in the area surrounding where the X-ray beam enters the body.
- the blanket-like radiation shield may be connected to the radiation shield(s) on the C-arm.
- the radiation protection device 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 slot or opening is provided to fit the radiation shield around the patient's body.
- a soft, flexible material surrounds the opening to comfortably fit the radiation shield to the contours of the patient's body and to accommodate some motion of the C-arm relative to the patient.
- the radiation protection device has a first conical or cylindrical radiation shield that extends from the X-ray source to the patient or to the procedure table and a second conical or cylindrical radiation shield that extends from the patient to the image intensifier.
- the first radiation shield and the second radiation shield have length or height adjustments to fit the device to the patient and to accommodate motion of the C-arm relative to the patient.
- a soft, flexible material surrounds the openings of the first radiation shield and the second radiation shield to comfortably fit them to the contours of the patient's body.
- the radiation protection device has electric motors or the like for withdrawing and advancing the first radiation shield and the second radiation shield from contact with the patient so that the C-arm can be freely moved and repositioned relative to the patient.
- the second radiation shield may have one or more hand ports to allow the operator to work on the area of the patient under the second radiation shield without withdrawing it from contact with the patient.
- Each embodiment of the radiation protection device may also include a blanket-like radiation shield that covers the patient in the area surrounding where the X-ray beam enters the body.

- the X-ray source 102 and the image intensifier 104 are placed on opposite sides of the portion of the patient's body to be imaged.
- the X-ray source 102 directs an X-ray beam through the patient's body toward the image intensifier 104, which captures the X-ray image and displays it on a monitor 108 in real time.
- the X-ray source 102 is positioned below the patient and the image intensifier 104 is positioned above as shown, however for some applications these positions may be reversed or the C-arm 106 may be positioned horizontally.
- the system may also include electronic memory for storing and replaying fluoro images and a cine camera for capturing fluoro images on film.
- the C-arm 106 will be mounted beside or at the head end of a procedure table. The C-arm 106 can be moved and rotated to position the X-ray source 102 and the image intensifier 104 for the best images of the target anatomy.
- the X-ray source 102 is positioned below the patient and the image intensifier 104 is positioned above as shown, however for some applications these positions may be reversed or the C-arm 106 may be positioned horizontally or at an oblique angle.

- the first layer can be build from uranium, lead and gold among others.
- the second layer may be made of tin, and indium among others and the third layer made of zinc, copper, nickel and chromium among others.
- the shielding material may be flexible, such as lead filled rubber, and it may be optically transparent, such as lead filled glass or a transparent X-ray opaque plastic.
- a flexible polymeric X-ray opaque material called DEMRON is available from Radiation Shielding Technologies.
- FIG. 3 illustrates a variation of the radiation protection device 110 of FIG. 2 in which the radiation shield 112 has a C-arm attached portion 126 and a patient-stationary portion 128.
- An overlapping, sliding joint 130 between the C-arm attached portion 126 and the patient-stationary portion 128 allows a greater range of motion of the C-arm 106 relative to the patient.
- a flap 124 of X-ray opaque material preferably a flexible material, may be provided to cover a portion of the opening 120 after it has been passed around a body part.
- the flap 124 may be removably attached, for example using magnets, snaps or hook-and-loop fasteners.
- FIG. 4 illustrates an embodiment of the radiation protection device 130 with a first radiation shield 132 and a second radiation shield 134 mounted on the C-arm 106 of the fluoroscopy system 100.
- the first radiation shield 132 is approximately conical or cylindrical in shape and extends from the X-ray source 102 to the patient, or to the procedure table 140 as appropriate for the body part being imaged.
- the second radiation shield 134 is also approximately conical or cylindrical in shape and extends from the image intensifier 104 to the patient.
- the radiation shields 132, 134 are typically open on the ends closest to the patient, but, optionally, the openings can be covered with a material that is transparent to X-rays.
- the first radiation shield 132 and the second radiation shield 134 have length or height adjustments 136, 138 to fit the device to the patient and to accommodate motion of the C-arm 106 relative to the patient.
- the length or height adjustments 136, 138 may be configured as overlapping telescopic joints, expandable bellows joints or the like.
- a pad 142, 144 of soft, flexible material surrounds the openings of the first radiation shield 132 and the second radiation shield 134 to comfortably fit them to the contours of the patient's body.
- the pads 142, 144 around the openings may be an inflatable or foam-filled rim of lead-filled rubber or other soft, conformable structure.
- the length or height adjustments 136, 138 and the conformable pads 142, 144 allow for a significant degree of repositioning of the C-arm 106 relative to the patient without having to readjust the radiation shields 132, 134.
- the length or height adjustments 136, 138 may be spring loaded with a light spring force to keep the radiation shields 132, 134 in contact with the patient when the C-arm 106 is adjusted without causing discomfort to the patient.
- the radiation shields 132, 134 will preferably be withdrawn from contacting the patient in order to allow free motion of the C-arm 106.
- the second radiation shield 134 may have one or more hand ports to allow the operator to work on the area of the patient under the second radiation shield 134 without withdrawing it from contact with the patient.
- FIG. 5 illustrates a radiation shield 134 with a single hand port 150 large enough for both of the operator's hands and/or one or more instruments to fit through.
- the hand port 150 is preferably fitted with a closure 156 of radiation shielding material to prevent X-rays from escaping through the hand port 150.

- Each of the hand ports 152, 154 is preferably fitted with a closure 156 of radiation shielding material to prevent X-rays from escaping through the hand ports 152, 154.
- the radiation shield 134 when a hand port is included in the radiation protection device 130, at least a portion of the radiation shield 134 will be made of transparent radiation shielding material so that the operator can see the area under the radiation shield 134. If the operator needs to have the hands inside of the radiation shield 134 while the fluoroscope 100 is operating, it is highly recommended that radiation shielding gloves be worn. In an alternate embodiment, a pair of radiation shielding gloves could be incorporated into the hand ports 152, 154.
- the radiation protection device 130 may be motorized for extending and retracting the first radiation shield 132 and the second radiation shield 134 from contact with the patient so that the C-arm can be freely moved and repositioned relative to the patient.
- FIG. 7 illustrates an embodiment of the radiation protection device 130 with motors 156, 158 for extending and retracting the first radiation shield 132 and the second radiation shield 134.
- the motors 156, 158 may be electric motors with a rack and pinion mechanism, a scissors mechanism, or other mechanism 133, 135 for translating the rotary motion of the motor into linear motion of the radiation shields 132, 134.
- the operating mechanism may be spring loaded with a light spring force to keep the radiation shields 132, 134 in contact with the patient when the C-arm 106 is adjusted without causing discomfort to the patient.
- the radiation shields 132, 134 will preferably be withdrawn from contacting the patient in order to allow free motion of the C-arm 106.
- pneumatic or hydraulic actuators may be used in place of the electric motors.
- the radiation protection device 130 will also include sensors 160, 162, such as proximity sensors, optical sensors, contact sensors, etc., that will stop the telescopic extension of the radiation shields 132, 134 when they are in the right contact with the patient.
- the conforming pads 142, 144 around the openings of the radiation shields 132, 134 mechanized to operate in a coordinated sequence with the extension and retraction of the radiation shields 132, 134.
- the conforming pads 142, 144 could be inflatable.
- the radiation shields 132, 134 would extend telescopically with the pads 142, 144 deflated until the sensors 160, 162 detect close proximity or initial contact with the patient's body, then the radiation shields 132, 134 would stop extending and the pads 142, 144 would inflate to close any gap left between the radiation shields 132, 134 and the patient.
- force sensors connected with the motors 156, 158 could be used to sense when the radiation shields 132, 134 are in contact with the patient.
- An interlock switch could be included to prevent the fluoroscope 100 from operating unless the sensors 160, 162 confirm that the radiation shields 132, 134 are in contact with the patient's body.
- one or more X-ray detectors could be positioned on or near the radiation protection device 130 outside of the radiation shields 132, 134 to detect X-ray leakage and connected to an interlock switch that shuts down the X-ray source if stray X-ray radiation is detected.
- Each embodiment of the radiation protection device may also include a blanket-like radiation shield that covers the patient in the area surrounding where the X-ray beam enters the body.
- the blanket-like radiation shield may be connected to the radiation shield(s) on the C- arm.
- FIG. 8 illustrates a blanket-like radiation shield 170 that covers the patient except the area that is being imaged.
- the blanket-like radiation shield 170 is preferably made of a flexible X-ray opaque material that covers most of the patient, except a fenestrated area 172 over the portion of the patient that is to be imaged.
- a second fenestration may be positioned over the vascular access site, for example the femoral or brachial artery or the jugular vein.
- the radiation shielding material will provide protection equivalent to 0.5 mm of lead or greater.
- the blanket-like radiation shield 170 may have a removable cover for patient comfort and for ease in sanitizing the patient-contact portions of the device.
- the removable cover may be washable and reusable or it may be a single-use sterile disposable cover.
- FIG. 9 illustrates a radiation shield 180 elevated slightly above and surrounding the patient, except a fenestrated area 182 over the portion of the patient that is to be imaged. If a rigid radiation shielding material is used, the radiation shield 180 may be self-supporting. Otherwise, a flexible radiation shielding material supported on a frame over the patient.
- another radiation shield may extend under the patient, with another fenestration under the portion of the patient to be imaged.
- this radiation shield may be an extension of the blanket-like radiation shield 170, 180 that is over the patient.
- the procedure table may be made partially of radiation shielding material with an X-ray transparent portion beneath the portion of the patient to be imaged, however this option potential limits the usability of the procedure table for different types of procedures.
- FIG. 10 illustrates a radiation shield 190 suspended from the X-ray source 102 of the fluoroscopy system 100.
- This is a curtain-like radiation shield 190 that hangs down between the X-ray source 102 and the floor to stop scattered X-ray radiation.
- This radiation shield 190 may be used separately or in combination with one of the embodiments of the radiation protection device described above.
