1. A method for establishing radiation beam parameters for delivery of radiotherapy treatment to a patient using a radiotherapy treatment device, the method comprising:
- a. orienting a wand with respect to the patient to establish a beam entry point;
b. acquiring positional parameters characterizing wand positioning with respect to a room coordinate system;
c. defining, in the room coordinate system, a beam angle consistent with the beam entry point;
d. obtaining one or more images of the patient'"'"'s internal anatomy; and
e. visually representing portions of the patient'"'"'s internal anatomy within a beam area corresponding to the defined beam angle, wherein the visual representations of the patient'"'"'s internal anatomy comprises digitized images of one or more internal anatomical features of the patient'"'"'s anatomy according to a beam'"'"'s eye view of a radiation treatment device, wherein the beam'"'"'s eye view is oriented along the defined beam angle.

Abstract
Radiation beam parameters are determined by manipulating a tool about a patient in order to determine a desired beam entry point and/or beam angle. In certain embodiments, a visual representation of the beam may be displayed along with images of internal and external anatomical features of the patient, and used to determine couch and/or gantry manipulation parameters to move the patient into a desired position with respect to a treatment delivery device.

18. A system for establishing radiation beam parameters for treatment of a patient, the system comprising:
-
a. a tool; b. a tool tracking device for sensing an orientation of the tool with respect to the patient to establish at least a beam entry point; c. a register for storing one or more images of the patient'"'"'s internal anatomy; and d. a processor for characterizing the beam entry point with respect to a room coordinate system, defining a beam angle consistent with the beam entry point and creating a visual representation of portions of the patient'"'"'s internal anatomy within a beam area corresponding to the defined beam angle, wherein the visual representations of the patient'"'"'s internal anatomy comprise digitized images of one or more internal anatomical features of the patient'"'"'s anatomy according to a beam'"'"'s eye view of a radiation treatment device, wherein the beam'"'"'s eye view is oriented along the desired beam angle. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
