Patent Number: 
Section: claims

1. An apparatus for altering the radiation intensity delivered from a radiation source to a patient for medical treatment of the patient comprising, in combination: a plate member for holding a plurality of radiation modulating devices used for radiation treatment of the patient; and  a frame member coupled to the radiation source for holding and locking the plate member, the frame member allowing the plate member to be positioned between the radiation source and a target area of the patient wherein the frame member allows the plate member to rotate within the frame member so different radiation modulating devices may be positioned between the radiation source and the target area of the patient to alter the radiation intensity delivered to the patient for medical treatment. 2. An apparatus for altering the radiation intensity delivered from a radiation source in accordance with  claim 1  wherein the plate member comprises a plurality of openings formed around the periphery of the plate member for holding the plurality of radiation modulating devices. claim 1 3. An apparatus for altering the radiation intensity delivered from a radiation source in accordance with  claim 1  wherein the plate member comprises at least one handle formed on the plate member. claim 1 4. An apparatus for altering the radiation intensity delivered from a radiation source in accordance with  claim 1  wherein in the frame member comprises: claim 1 a housing which is positioned around a section of the plate member when the plate member is placed within the frame member;  a channeling which runs along a length of the housing;  a cross bar member coupled between a first end and a second end of the housing; and  a pair of support arms coupled to the housing for coupling the frame member to the radiation source. 5. An apparatus for altering the radiation intensity delivered from a radiation source in accordance with  claim 4  wherein the frame member further comprises a rotatable arm member rotatably coupled to the cross bar for securing the plate member within the frame member. claim 4 6. An apparatus for altering the radiation intensity delivered from a radiation source in accordance with  claim 5  wherein the rotatable arm member has a raised member coupled to an end of the rotatable arm. claim 5 7. An apparatus for altering the radiation intensity delivered from a radiation source in accordance with  claim 4  wherein the frame member further comprises a plurality of rollers located within the channeling for rotating the plate member within the channeling. claim 4 8. An apparatus for altering the radiation intensity delivered from a radiation source comprising, in combination: a plate member having a plurality of openings formed around the periphery of the plate member for holding a plurality of radiation modulating devices; and  a frame member coupled to the radiation source for holding the plate member between the radiation source and a target area wherein the frame member allows the plate member to rotate within the frame member so different radiation modulating devices may be positioned between the radiation source and the target area to alter the radiation intensity delivered wherein the frame member comprises:  a housing which is positioned around a section of the plate member when the plate member is placed within the frame member;  a channeling which runs along a length of the housing;  a cross bar member coupled between a first end and a second end of the housing;  a pair of support arms coupled to the housing for coupling the frame member to the radiation source; and  a rotatable arm member rotatable coupled to the cross bar for securing the plate member within the frame member. 9. An apparatus for altering the radiation intensity delivered from a radiation source in accordance with  claim 8  wherein the plate member further comprises at least one handle formed on the plate member. claim 8 10. An apparatus for altering the radiation intensity delivered from a radiation source in accordance with  claim 8  wherein the rotatable arm member has a raised member coupled to an end of the rotatable arm. claim 8 11. An apparatus for altering the radiation intensity delivered from a radiation source in accordance with  claim 8  wherein the frame member further comprises a plurality of rollers located within the channeling for rotating the plate member within the channeling. claim 8
