A system (30), tracker, program product, and methods to facilitate and verify proper target alignment for radiation delivery are provided. The system (30) includes a radiation delivery apparatus (31) having a radiation emitter (33), a rotating assembly (35) controlled by a controller (39), and an application computer (41) which provides treatment delivery instructions to the controller (39). The system (30) also includes a trackable body (71, 73, 75, 77, 79) having a trackable body reference point (81, 83, 85, 87, 89) to be positioned adjacent a surface point of a patient to determine a position of such surface point. The system (30) also includes an apparatus to track a trackable body which has a trackable body detector (53) to detect a position of indicators (90) carried by the trackable body and a trackable body determiner (55) to determine a position of the trackable body reference point (81, 83, 85, 87, 89). The system (30) also includes a target alignment analyzing computer (61) having memory (123) and target alignment analyzing program product (63) stored therein to aid a user of the system (30) to make and display various patient body-surface related measurements. |
