ABSTRACT:
A patient orienting device accurately positions a patient with reference to a source of diagnostic or therapeutic radiation. The planes of light are appliable to the body of the patient and correspond to the sagittal, frontal, and transverse planes of the body. The device includes a first light source establishing a first light plane lying in the sagittal plane. The first light source is typically located at the foot of the patient. A second light souce establishes second and third mutually perpendicular planes of light. The second light source is typically located at the head of the patient. The light source is positioned so that one of the light planes is co-planar with the first light plane and so that the other light plane lies in the frontal plane. A third light source establishes fourth and fifth mutually perpendicular planes of light. The third source lies on one side of the sagittal plane so that the fourth and fifth light planes intersect the first light plane normal to the latter. A fourth light source establishes sixth and seventh mutually perpendicular light planes. The fourth light source lies on the other side of the first light plane so that the sixth and seventh light planes perpendicularly intersect the first light plane. The fourth and sixth light planes lie in the frontal reference plane, along with the second light plane. The fifth and seventh light planes lie in the transverse reference plane.
