Abstract

The present disclosure provides an irradiation treatment apparatus having a generally vertical patient support surface; a patient securing mechanism arranged to secure a patient in a fixed relation to the patient support surface; a rotation platform secured at one end of the patient support surface and arranged to rotate the patient support surface about a generally vertical axis and optionally translate the patient support surface at least partially about a plane generally orthogonal to the generally vertical axis; an imager exhibiting a first mode in which the imager occludes radiation from a fixed beam irradiation source and a second mode in which the imager enables irradiation from the fixed beam irradiation source; and a vertical translation mechanism in communication with the patient support surface and arranged to translate the patient support surface along the generally vertical axis from a loading position to an irradiation position.

Claims16

Dependent claims

An irradiation treatment apparatus comprising:

a patient support surface;
a rotation mechanism;
a patient securing mechanism arranged to secure a patient in a fixed relation to said patient support surface;
a platform in communication with said patient support surface and said rotation mechanism and arranged to rotate said patient support surface about a generally vertical axis;
an imager exhibiting a window and a first mode in which said imager occludes radiation from a fixed beam irradiation source when said window is closed and a second mode in which said imager enables irradiation from the fixed beam irradiation source when said window is open;
a vertical translation mechanism in communication with said patient support surface and arranged to translate said patient support surface along said generally vertical axis from a loading position to an irradiation position;
and
a control unit in communication with said imager, said control unit operative to:
set said imager to said first mode;
translate said patient support system vertically through said imager via said vertical translation mechanism, and
operate said imager to thereby image a section of the patient.

8 more elements

A method comprising:

securing a patient to a patient support surface;
vertically translating the secured patient so as to approximately align a target tissue of the secured patient with an treatment irradiation beam ultimately exiting a fixed beam irradiation source;
rotating the secured patient about a generally vertical axis so as to approximately present the target tissue to the treatment irradiation beam ultimately exiting the fixed beam irradiation source at a first desired angle;
providing an imager exhibiting a window and a first mode in which said provided imager occludes radiation from a fixed beam irradiation source when said window is closed and a second mode in which said provided imager enables irradiation from the fixed beam irradiation source when said window is open;
setting said provided imager to said first mode;
translating said patient support surface vertically through said provided imager via said vertical translation mechanism thereby imaging, via said imager in said first mode, said target tissue aligned with the treatment irradiation beam ultimately exiting the fixed beam irradiation source;
setting said imager to said second mode;
and
irradiating the target tissue from said fixed beam irradiation source at said first desired angle.
