Abstract
Abstract This specification discloses a device for positioning the neck of a patient relative to a positron camera with gamma ray detectors on which stereoscopic images are formed for examination of the thyroid gland of the patient. The device consists essentially of two telescopic, cylindrical members of plastic, a ring clamp for securing one of the telescopic members to the collimator of the camera, and means for securing the telescopic members in an adjusted relation. Calibrations are provided on one of the telescopic members which cooperate with an end edge of the other member to indicate the length of the device in an adjusted position. One of the telescopic members is formed with a recess at the top which receives the neck of a patient immediately below the chin and also with a pair of recesses at its opposite sides to accommodate the hands of an examining physician.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
181 words
In a device for positioning a patient relative to a nuclear medicine pho gamma scintillator camera including a collimator, for thyroid gland examination purposes: a. a cylindrical, plastic base member having opposed ends; b. means for detachably mounting one end of said base member on said collimator; c. a cylindrical, plastic neck engaging member in telescoping relation to said base member and having an inner end edge and an outer end; d. means for maintaining said base member and neck engaging member in angular alignment during axial adjustment thereof; e. means for securing an axially adjusted position of said base and neck engaging members; f. said neck engaging member being formed with a recess in what is the upper region of said neck engaging member when the device is in effective position and which recess receives the neck of a patient, and g. said neck engaging member being formed with a pair of recesses at the opposite sides thereof which are dimensioned to permit the passage of the hand of an examining physician therethrough when the device is in effective position.

In a device for positioning a patient relative to a nuclear medicine pho gamma scintillator camera including a collimator, for thyroid gland examination purposes: a. a cylindrical, plastic base member having opposed ends; b. means for detachably mounting one end of said base member on said collimator; c. a cylindrical, plastic neck engaging member in telescoping relation to said base member and having an inner end edge and an outer end; d. means for maintaining said base member and neck engaging member in angular alignment during axial adjustment thereof; e. means for securing an axially adjusted position of said base and neck engaging members; f. said neck engaging member being formed with a recess in what is the upper region of said neck engaging member when the device is in effective position and which recess receives the neck of a patient, and g. said neck engaging member being formed with a pair of recesses at the opposite sides thereof which are dimensioned to permit the passage of the hand of an examining physician therethrough when the device is in effective position.
Claim 3
Dependent Claim
36 words
The device of claim 1, together with calibrations on one of said members which cooperate with a structural element on the other of said members to indicate an adjusted axial length of said members when assembled.
Claim 4
Dependent Claim
60 words
The device of claim 1 in which the end of said base member which is mounted on the collimator is formed with a plurality of angularly spaced slots opening onto the end edge thereof, together with a ring clamp disposed about the slotted end of said base member and constituting the means for mounting the base member on the collimator.
Claim 5
Dependent Claim
53 words
The device of claim 1 in which the means for maintaining the base member and neck engaging member in angular alignment comprises a pair of longItudinal slots formed in said members and which align, together with a set screw passing through each pair of aligned slots and a nut on each set screw.
Claim 6
Dependent Claim
61 words
The device of claim 4 in which the neck engaging member is received within the base member and calibrations on the outer surface of said base member along the sides of one of said slots, and which calibrations cooperate with the inner end edge of said neck engaging member in indicating the effective length of the device in an adjusted position.
Claim 7
Dependent Claim
15 words
The device of claim 4 in which said slots are angularly spaced apart about 120*.
Claim 8
Dependent Claim
86 words
The device of claim 1 in which said base member is formed with a recess opening onto the end remote from that which is secured to the collimator and which recess is in alignment with the recess in the top of the neck engaging member, and recesses at the sides of said base member opening onto the end remote from the end which is secured to the collimator, said last mentioned recesses being in alignment with said recesses in the sides of said neck engaging member.
Claim 9
Dependent Claim
18 words
The device of claim 1 in which said base member and said neck engaging member are of acrylic.
Claim 10
Dependent Claim
