Multiple room radiation treatment system

Abstract

The present invention refers to a radiation system (1) comprising an excentric gantry (100) arranged in connection with multiple treatment rooms (61-68) separated by radiation-shielding separating members (71-78). A movable rotation head (120) is connected to the gantry (100) and is able to move between, and direct a radiation beam (110) into, the treatment rooms (61-68). A simulator head (200-1 to 200-8) is preferably arranged together with the radiation system so it can be used in each respective treatment room (61-68). In such a case, while a first subject (40-1) is being irradiated in a first room (61), a treatment set-up procedure, including correct positioning of subjects (40-2 to 40-8) and irradiation simulation, can simultaneously take place for the other subjects (40-2 to 40-8) in the other treatment rooms (62 to 68).

Description

Technical field [0001] The present invention relates generally to a radiation system, and more particularly to such a system capable of guiding a radiation beam to multiple treatment rooms. Background technique [0002] In the past few decades, the field of radiotherapy and diagnosis has developed significantly. External beam radiotherapy accelerators, brachytherapy and other professional radiotherapy instruments have all been greatly improved. The development of quality and adaptability of therapeutic radiation beams includes: new objects and filters, improved accelerators, refractive index for beam shaping through new transmitters, collimators and scanning systems, and beam compensation Technology etc. Improved dosimetry and geometric treatment confirmation methods were also introduced. In addition, a new treatment planning system that can achieve biological optimization of the output beam intensity distribution is now available. [0003] In the field of multiple and single seg...

AI Technical Summary

Problems solved by technology

[0005] The problem with prior art radiotherapy machines is their limited throughput, ie in terms of the total number of patients who can be treated in a given time interval

Even though this treatment system uses the same ion source and beam accelerator system for all three gantry, the problems found above with respect to (low) patient throughput and cost efficiency still exist in each gantry of this treatment system

[0010] In addition, many treatments with charged particles are not established according to the principle of concentric setting, for example in the treatment of electrons, protons or light ions, a fixed SSD treatment with a fixed distance between the particle source and the patient surface can be performed such that Concentric therapy equipment is not so important
