Improved radiation therapy with field-in-field multi-leaf collimator, utilizing leaf sequencing Field-in-Field's (FIF) to accurately reproduce the input fluence map or original optimized dose distribution. The number of apertures used is constrained to a user-specified value all the way down to as few as 2 apertures which significantly magnifies the effect of poorly formed apertures. The disclosed invention further includes producing fluence maps with a homogenous dose throughout the treated volume utilizing leaf-sequencing Field-in-Field that reproduces more precise input fluence maps to yield optimized dose distribution.

A system for particle beam therapy has an adjustable gantry for beam delivery to a patient site. The gantry has a beam coupling section, a first beam bending section with beam deflection and/or focusing magnets. A beam transport section receiving the particle beam from the first beam bending section and guiding the particle beam to a second beam bending section. The beam exits at a window of a beam nozzle. A patient table/chair is rotatable in the horizontal plane or in a plane being parallel to the horizontal plane and optionally being adjustable vertically. The gantry is supported by a tilting mechanism allowing the gantry to be tilted vertically by an angle 1[90; +90]. A rotation mechanism is disposed in a way that the second beam bending section and the beam nozzle are rotatable by an angle 2[180; +180] around a direction given by the angle 1.

A system or method for radiation treatment optimized for non-coplanar delivery, which includes a first collimator affixed to a gantry and a second collimator movably attached to the gantry to provide the second collimator a translation movement out of a gantry rotation plane. The system or method also includes a third collimator configured to collimate the beam in a direction of a target in the patient's body. The beam collimated by the third collimator is configured to follow the target during treatment. A method of performing rotation setup correction by rotating the treatment beam, without rotating the patient.

A polymeric radiation-source with customized geometries to maximize receipt of radiation into treatment areas that is formed from either radioisotopes molecularly bonded to a polymer or radioisotopes encased within a polymer.

The present invention provides a means for achieving greater ability to negotiate small radii like 5 mm of curvature in the human body to treat tumors, for example, with radioactive materials. This is accomplished by incorporating the source capsule into a flexible housing, which, in its simplest configuration, eliminates the direct connection of the source capsule to the driving cable, adding a degree of flexibility that is not available with a direct connection of the source capsule to the driving cable as in the presently available source capsules, and further providing segmented source capsules, and further providing devices for shielding of tissue using the segmented source assemblies.

A method for producing a model for the application of radiation to a body surface area of a living being for cosmetic or therapeutic purposes is provided. The method includes defining a body surface area to which radiation shall be applied; producing a model having at least one surface which has the inverted shape of the defined body surface area, so that the model is configured to fit on the defined body surface area; and providing a radioactive isotope to the model during its production or after its production. Further, the use of the model in a cosmetic treatment of the skin is provided. The model, for cosmetic or therapeutic purposes, includes a surface which has the inverted shape of a defined body surface area which shall be treated with radiation.

Systems, methods, and computer-readable media for enabling ultraviolet radiation treatments are provided.

These teachings provide for quickly yet accurately forming an influence matrix by generating the influence matrix via integration with a Monte Carlo particle transport simulation. The resultant influence matrix can then be utilized in an ordinary manner when optimizing a radiation treatment plan. By one approach, the foregoing comprises generating the influence matrix via integration with a Monte Carlo particle transport simulation on a particle-by-particle basis. For example, for each particle, these teachings can provide for identifying a spot to which the particle belongs and then adding a dose deposited by the particle during transport to an influence matrix element that corresponds to a spot to which the particle belongs and a voxel to where the dose was deposited.
