A system for delivery of high dosage of radiation to a targeted spinal area is provided. This is accomplished by a system which provides for precise immobilization and positioning of the treated spinal area during dose planning and treatment via stereotactic radiosurgery. Advantages of the system include convenience to the patient, enhanced efficacy, and reduced risk of radiotoxicity to non-target tissues.

An X-ray apparatus for image acquisition and a related method. The apparatus comprises a field-of-view corrector (CS) configured to receive a scout image (SI) acquired by the imager with a tentative collimator setting in a pre-shot imaging phase where said imager operates with a low dosage radiation cone causing the detector to register the scout image. The low dosage cone has, in the detector's image plane, a first cross section smaller than the total area of the detector surface. The field-of-view corrector (CS) uses said scout image to establish field-of-view correction information for a subsequent imaging phase where the imager is to operate with a high dosage radiation cone, the high dosage higher than the low dosage.

Cancer treatment is provided, by irradiating an individual with a localized, high single dose or short course of doses at a primary tumor site; collecting T cells from the individual after a period of time sufficient activation of an anti-tumor response; treating the individual with an effective dose of dose of chemotherapy; and reintroducing the T cell population back to the individual.

The invention discloses a movable box type combined shielding system which comprises a container, an in-box radiation shield, an out-box radiation shield and a photon shielding plate. A radioactive source generating device is arranged in the container; the space between the radioactive source generating device and the inner wall of the container is fixedly filled with the in-box radiation shield; the outer wall of the container is detachably covered with the out-box radiation shield; the photon shielding plate is arranged on the outer wall of the container in a sliding mode and used for sliding to an active area when the out-box radiation shielding body is detached to shield active area rays. According to the movable box type combined shielding system, the radioactive source generating device can run and be transported in the container; when the radioactive source generating device runs, the in-box radiation shield and the out-box radiation shield can be combined to shield high-dose radiation generated when the radioactive source generating device runs; when a container body is transported, the in-box radiation shield and the container body are detached, and the photon shielding plate moves to the active area to shield rays generated by neutron activation of a container active area structure material.
