DRIVING TYPE PATIENT PLATFORM, CONTROL DEVICE FOR DRIVING TYPE PATIENT PLATFORM, CONTROL PROGRAM FOR DRIVING TYPE PATIENT PLATFORM, AND PARTICLE BEAM THERAPY SYSTEM UTILIZING THESE ITEMS
The objective is to obtain a driving type patient platform that can efficiently perform positioning work for making the position and the posture of a diseased site coincide with those established when a treatment plan is generated.There are provided translation unit (3, 4, and 5) that translate a top board (8) in the X direction, the Y direction, and the Z direction, respectively, in a fixed coordinate system (10) rotation unit (6, 7, and 8) that rotate the top board (8) in the θ direction around the X axis, the φ direction around the Y axis, and the ξ direction around the Z axis, respectively and a control device that controls the translation unit (3, 4, and 5) and the rotation unit (6, 7, and 8), based on an inputted desired rotation center point (P) and an inputted desired rotation angle. The control device is provided with a rotation drive signal generation unit that generates a rotation drive signal for moving the top board (8) in a rotating manner from the reference state "a" of the translation unit (3, 4, and 5) and the rotation unit (6, 7, and 8) to a desired rotation angle and a translation drive signal generation unit that generates a translation drive signal for translating the translation unit (3, 4, and 5) in such a way that the amount of translation movement, of the desired rotation center point (P), that is caused by the rotation movement becomes the same as or smaller than a predetermined value.本發明之目的是獲得對準治療計劃時策定之位置之定位作業可以有效率地進行之驅動式診療台。本發明之驅動式診療台具備有:平移手段3、4、5,相對於固定座標系10,使頂板在X軸方向、Y軸方向、Z軸方向之各個軸方向平移;旋轉手段6、7、8,使頂板8在圍繞X軸之θ方向、圍繞Y軸之Φ方向、圍繞Z軸之ξ方向之各個方向旋轉;及控制裝置,根據被輸入之希望旋轉中心點P和希望旋轉角,控制平移手段3、4、5和旋轉手段6、7、8;其中,控制裝置具有:旋轉驅動信號產生手段,用來產生使頂板8從平移手段3、4、5和旋轉手段6、7、8之基準狀態旋轉移動到希望旋轉角之旋轉驅動信號;及平移驅動信號產生手段,用來產生平移驅動信號,令平移手段3、4、5平移,使利用旋轉移動產生之希望旋轉中心點P之平移移動量在既定值以下。1...驅動式診療台(診療台)2...床面3...診療台構成部件(X平移部件)4...診療台構成部件(Z平移部件)5...診療台構成部件(Y平移部件)6...診療台構成部件(擺動旋轉部件)7...診療台構成部件(橫搖旋轉部件)8...診療台構成部件(縱搖旋轉部件、頂板)
