Embodiment Construction

[0030] The invention is based on some general more or less purely geometrical considerations. The stability problem of the frame and the bed according to the state of the art is based on the support of the frame and the positioning of the bed. The frame is generally placed substantially adjacent to the axis of rotation positioned substantially in extension of the bed. The bed can only be supported at one end due to interference with the movement of the frame, and the unstable frame design is based on the requirement not to unduly interfere with the bed.

[0031] In the present invention, some geometrical considerations are changed. In order to be able to provide a stable bed design, only a space is reserved around the bed for the bed components, which also includes the space for the body to be irradiated. Components with racks are not permitted in this space. In all possible cases, all moving parts of the gantry are located at a distance from the axis of rotation of the rad...

Abstract

An irradiation device provides a free volume around the longitudinal axis of the body ( 13 ) around the body to be irradiated. The supporting parts of a gantry ( 1, 2 ) are situated substantially radially with respect to the longitudinal axis. The gantry includes an inner gantry part ( 1 ) with at least two supporting locations (S) to an outer gantry portion ( 2 ).The support locations (S) are situated at each side of a treatment volume ( 12 ). A radiation head ( 8 ), mechanically attached to the inner gantry part ( 1 ) and arranged to direct radiation to the treatment volume ( 12 ) is movable around the treatment volume ( 12 ). In preferred embodiments, the parts ( 20, 21, 22, 23 ) of the gantry are formed as rings, leaving a free space along the rotational axis ( 9 ). A body-supporting couch ( 10 ) is arranged along the rotational axis extending through the hollow parts ( 20, 21, 22, 23 ). The radiation head ( 8 ) is preferably movable in a path also perpendicular to the rotation axis ( 9 ).

Description

technical field [0001] The present invention relates to devices and methods for irradiating, and in particular to devices and methods for irradiating in multiple directions. Background of the invention [0002] Radiation in the form of electromagnetic radiation or particle radiation is used today for many purposes, for example for the modification of materials, for disinfection, and for medical diagnosis and treatment. These different purposes put forward different requirements on the methods and devices used, but there are also many commonalities. [0003] In the fields of radiotherapy and radiosurgery, the usual general approach is to place patients on a bed. Point the radiation head at the relevant patient in order to direct the beam to a certain treatment volume, eg a tumor. A general requirement for this application is to maximize the dose in the treatment space and minimize the dose in tissues outside the treatment zone. One way to achieve this requirement is to irr...
