System, apparatus and methods specialized for breast and related tissue radiation therapy and imaging of a prone patient but also usable for supine patient if desired or needed. A special treatment radiation source such as a LINAC unit generates radiation of types and energy ranges specifically matched to breast tissue. Any one or more of several imaging technologies may be used to localize the tissue to be irradiated and to generate information for therapy planning, adjustment, and verification.

1. A method of verifying brachytherapy treatment comprising: placing a patient in a prone position on a patient table surface having an opening or depression in which a patient's breast for brachytherapy treatment extends downwardly;imaging the breast with radiation to verify brachytherapy related parameters using an imaging device located below the patient table surface;said brachytherapy related parameters including a position of one or more brachytherapy devices located inside the patient's breast relative to anatomy of the breast; andgenerating image data for the patent's breast for assessing brachytherapy-related parameters, including image data related to said position of said one or more brachytherapy devices relative to breast tissue adjacent to said one or more brachytherapy devices. 2. A method as in claim 1 including delivering therapy radiation from an external source to the patient's breast and/or related anatomy while the patient is in said prone position. 3. A method as in claim 1 in which said image data includes data for verifying a position of said one or more brachytherapy devices configured for emitting treatment radiation from one or more locations inside the patient's breast relative to anatomy in the patient's breast. 4. A method as in claim 1 in which said image data includes data for verifying effects of brachytherapy on anatomy in the patent's breast. 5. A method of breast brachytherapy comprising: placing a patient in a prone position on a patient table surface having an opening or depression in which only a first breast of the patient extends downwardly;pre-treatment imaging of said first breast with penetrating radiation using an imaging device located below the patient table surface to obtain three-dimensional image data and using said data for at least one of (i) assessing the first breast for brachytherapy treatment suitability and (ii) creating a brachytherapy treatment plan for said first breast;carrying out brachytherapy treatment of the first breast using therapy radiation emitted from one or more brachytherapy devices inside said first breast and verifying placement of said one or more brachytherapy devices in the first breast with the patient in said prone position on said patient table; andpost-treatment imaging of the first breast using said imaging device located below the table surface to assess results of said brachytherapy treatment. 6. The method of claim 5 in which said brachytherapy treatment comprises using plural radiation sources located in said first breast. 7. The method of claim 5 including treating said first breast with radiation from one or more radiation sources located outside said first breast. 8. The method as in claim 5 including imaging the first breast with said imaging device to verify placement of radiation sources inside said first breast relative to selected tissue of said first breast. 9. A system for breast brachytherapy treatment comprising: a patient table having a surface with an opening or depression forming an imaging space for a downwardly extending single breast of a patient in a prone position on the patient table surface;a penetrating radiation source using selectively emitting imaging radiation from below the patient table surface toward said imaging space;an imaging receptor generating pre-treatment image information from said imaging radiation after interaction thereof with the imaging space; anda processing unit configured to use said imaging information for at least one of (i) assessing said breast for brachytherapy treatment suitability and (ii) creating a brachytherapy treatment plan for said breast; andsaid imaging receptor being further configured to generate post-treatment imaging information from said imaging radiation, and said processing unit being further configured to use said post-treatment imaging information to provide treatment assessment results. 10. The system of claim 9 including a support for said penetrating radiation source configured to rotate the penetrating radiation source about a non-vertical axis. 11. The system of claim 9 in which said penetrating radiation source further includes a treatment radiation source that selectively emits treatment radiation from below the patient table surface, said treatment radiation being directed to said imaging space and conforming to said brachytherapy treatment plan. 12. The system of claim 11 including a support for said penetrating treatment radiation source configured to rotate the treatment radiation source about a non-vertical axis.
