Background technique
Currently a popular irradiation unit, accordingly it will usually be desirable to which point of irradiation is placed in the isocenter point of system, that is, with point of irradiation
Centered on, carry out rotary irradiation by radius of the Source Axis Distance of linear accelerator, the benefit of this pendulum position is any rotation angle of rack
Degree, beam can all pass through central point, realize efficient radiating irradiation.
In recent years, since magnetic resonance imaging is without ionising radiation, high soft tissue contrast, and can guiding in real time irradiation at
Picture, it is more and more concerned.Irradiation unit due to its proprietary design feature, no matter superconduction or permanent magnetism, all to aperture or opening
There are strict requirements, therefore the freedom degree for irradiating bed is very restricted.Traditional is put point of irradiation by mobile irradiation bed
It is difficult to realize under the system of guided by magnetic resonance to system isocenter point.
Current each producer both domestic and external truly realizes the rotation Isocenter irradiation to lesion not yet.
