| 英文摘要 | Heavy ion therapy is currently recognized as the most advanced cancer radiotherapy approach in the world. This article introduces a high-precision and non-contact measurement method based on close-range photogrammetry combined with a 3D control network of a laser tracker, which is used to guide the positioning and real-time target area monitoring for patients undergoing heavy ion radiotherapy. By the precise connection between the 3D control network of the laser tracker and the digital photogrammetry device, we position the photogrammetry system absolutely at the treatment isocenter, measuring the feature points of the target area on the patient's body surface. After that, the seven-parameter solution model is combined with the feature points to accurately determine the tumor position, as well as displaying its real-time location changes in the form of relative position to the treatment isocenter shown as six-degree-of-freedom parameters during radiotherapy, so that the patient may be guided to achieve a more reliable and efficient positioning. The research and design on the dual-camera close-range photogrammetry patient monitoring system has provided insights in the course of radiotherapy. That is to say, by monitoring the feature points on the patient's body surface, a real-time display of tumor displacement and a warning system for out-of-tolerance variances are established, controlling the treatment bed to stay on the tumor. This method could ensure the irradiation precision for the patient during the treatment and protect normal tissues from radiation exposure, optimizing the treatment outcome. Multiple patient positioning simulations have verified that the measurement precision of our photogrammetry-based method can meet the requirements of heavy ion radiotherapy patient positioning. |
