專利摘要(中)
一種標籤導引影像定位的方法包含：根據辨識設置有參考標籤之病患部位的參考影像而獲得的標籤空間位置資訊及放射醫療設備參考點與方向的位置方向資料定義出三維空間座標系統；根據標註有目標點和對應參考標籤位置的參考標記的該部位的三維醫學影像及系統中代表參考標籤位置的參考座標估算出系統中代表目標點位置的目標座標；及根據判斷系統中目標座標與代表醫療設備參考點位置的設備座標的距離和代表醫療設備方向的指向是否分別相符於部位的放射治療計畫中的距離和醫療設備入射方向之判斷結果輸出定位結果作為是否調整部位之擺位的依據。

專利摘要(英)
A tag-guided image positioning method includes: defining a three-dimensional space coordinate system based on tag space position information obtained by recognizing one or more reference images of a patient’s body part disposed with one of more reference tags, and on position-direction data related to the center of a radiation beam exit and the beam direction; estimating a target coordinate in the three-dimensional space coordinate system representing the position where the target treatment point of the patient’s body part is located based on a three-dimensional medical image of the patent part marked with a target treatment point and one or more reference marks corresponding to the position(s) where the reference tag(s) is(are) attached, and on one or more reference coordinates in the three-dimensional space coordinate system representing the position(s) where the reference tag(s) is(are) attached; and outputting a positioning result as a basis for whether the patient’s body part should be adjusted based on determining whether the distance between the target coordinate and a center coordinate in the three-dimensional space coordinate system representing the position where the center of the radiation beam exit is located and the direction in the three-dimensional space coordinate system representing the beam direction are respectively consistent with the predetermined distance and the incident beam direction in the radiation treatment plan of the patient’s body part.
