When radiation treatment is delivered to adjacent or contiguous tumor volumes with multiple fields, the geometric alignment of the beams is particularly critical. A beam alignment device has been developed that enables precise matching of such fields.
当使用多个射野对相邻或连续的肿瘤体积进行放射治疗时，射束的几何对准尤为关键。现已开发出一种射束对准装置，可实现此类射野的精确匹配。
