Noninvasive stereotactic apparatus and method for relating data between medical devices
First Claim
1. A noninvasive stereotactic apparatus for aligning a noninvasive stereotactic adapter mounted on a patient'"'"'s head with a medical device, the apparatus comprising:
- a frame adapted to be mounted with respect to the medical device, the frame having a frame centerline;
a rest plate connected to the frame for noninvasively supporting the patient'"'"'s head at a desired elevation;
a first alignment bracket having a length generally parallel to the frame centerline and being movably mounted to the frame, the first alignment bracket being movable in a first direction toward and away from the frame centerline for aligning the noninvasive stereotactic adapter and the patient'"'"'s head at a desired location with respect to the medical device; and
noninvasive movable positioners mechanically supported by the frame for maintaining the patient'"'"'s head at the desired location.

Abstract
A noninvasive alignment apparatus for providing a stereotactic interface between a noninvasive stereotactic adapter mounted on a patient'"'"'s head and a medical device, such as, an imaging device or a radiotherapy machine. The apparatus permits a method of noninvasive fractionated radiotherapy to be practiced. The alignment apparatus is constructed of separable arcuate segments to facilitate the insertion of the patient'"'"'s head and stereotactic adapter within the apparatus. The alignment apparatus further has various calibrated shafts for each of its movable elements, so that, after the alignment apparatus is initially positioned and adjusted on an imaging machine, its position with respect to the stereotactic adapter may be replicated later on a radiotherapy machine.

21. A noninvasive stereotactic apparatus for aligning a noninvasive stereotactic adapter mounted on a patient'"'"'s head with a medical device, the apparatus comprising:
-
a frame having opposite sides and adapted to be mounted with respect to the medical device, the frame including a first frame member, and a second frame member forming a forward side of the frame between the opposite sides, the second frame member being separable from and having one end pivotally connected to the first frame member; first and second alignment brackets connected to the opposite sides of the frame for aligning the noninvasive stereotactic adapter and the patient'"'"'s head at a desired location with respect to the medical device; and noninvasive movable positioners mechanically supported by the frame for maintaining the patient'"'"'s head at the desired location.

22. A method of performing stereotactic fractionated radiotherapy comprising:
-
a) mounting a noninvasive stereotactic adapter on a head of a subject; b) locating the head of the subject within a noninvasive alignment ring operatively positioned with respect to a collimator of a radiotherapy machine; c) moving the stereotactic adapter and the subject'"'"'s head to a predetermined location with respect to the alignment ring; d) coupling a fiducial device associated with the radiotherapy machine to the alignment ring; e) performing a radiotherapy treatment using the radiotherapy machine; f) removing the patient'"'"'s head from the noninvasive alignment ring and the noninvasive stereotactic adapter, whereby the radiotherapy treatment is performed using noninvasive appliances. - View Dependent Claims (23, 24)

25. A noninvasive stereotactic apparatus for aligning a noninvasive stereotactic adapter mounted on a patient'"'"'s head with a medical device, the apparatus comprising:
-
a frame adapted to be mounted with respect to the medical device, the frame having a frame centerline; a rest plate connected to the frame for noninvasively supporting the patient'"'"'s head at a desired elevation; a first alignment bracket having a length generally parallel to the frame centerline and being movably mounted to the frame, the first alignment bracket being movable in a direction generally perpendicular to the frame centerline and generally parallel to a plane defined by the frame for aligning the noninvasive stereotactic adapter and the patient'"'"'s head at a desired location with respect to the medical device; and noninvasive movable positioners mechanically supported by the frame for maintaining the patient'"'"'s head at the desired location.
