Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
An apparatus for radiation diagnosis to determine the amount of radiation emitted from a radioactive material administered to the body of a patient, said apparatus comprising; a. an upright elongate housing, b. an elongate support member secured to a lower end region of said housing and adapted to carry a chair for accommodating a patient; c. a single support stand mounted in said housing; d. a single support arm disposed above said elongate support member and connected to said stand for linear upward and downward movement with respect to the housing; e. a radiation detector defining a radiation entry aperture mounted on said support arm; f. means for permitting upward and downward pivotal movement of said detector; and g. means for effecting linear movement of said detector along said support arm, whereby the position of the radiation entry aperture of the detector with respect to the chair is variable.
Claim 2
Independent Claim
149 words
An apparatus for radiation diagnosis to determine the amount of radiation emitted from a radioactive material administered to the body of a patient, said apparatus comprising; a. an upright elongate housing, b. an elongate support member secured to a lower end region of said housing and adapted to carry a chair for accommodating a patient; c. a single support stand mounted in said housing; d. a single support arm disposed above said elongate support member and connected to said stand for linear upward and downward movement with respect to the housing; e. a radiation detector defining a radiation entry aperture mounted on said support arm; f. means for permitting upward and downward pivotal movement of said detector; and g. means for effecting linear movement of said detector along said support arm, whereby the position of the radiation entry aperture of the detector with respect to the chair is variable.
Claim 3
Dependent Claim
24 words
An apparatus as set forth in claim 1, wherein said support arm and said elongate support member are disposed in a common vertical plane.
Claim 4
Dependent Claim
37 words
An apparatus as set forth in claim 1, wherein said support stand is counterpoised and is vertically displaceable in the housing, the free end of the support stand being angled through 90* to form said support arm.
Claim 5
Dependent Claim
36 words
An apparatus as set forth in claim 3, wherein the means for effecting linear movement of the detector along the support arm include a carriage secured to said detector and slidably mounted on said support arm.
Claim 6
Dependent Claim
49 words
An apparatus as set forth in claim 4, wherein the means for permitting pivotal movement of said detector includes a substantially horizontal shaft extending transversely of the support arm from a side face of the carriage and releasable locking means for locking said detector in a desired pivoted position:
Claim 7
Dependent Claim
37 words
An apparatus as set forth in claim 1, wherein the means for accommodating the patient is a diagnostic chair, which chair is mounted for angular movement about a vertical axis, and a headrest carried by said chair.
Claim 8
Dependent Claim
37 words
An apparatus as set forth in claim 6, wherein the free end of said elongate support member is angled through 90*, the chair being mounted on the elongate support member to be displaceable along said free end.
Claim 9
Dependent Claim
22 words
An apparatus as set forth in claim 7, wherein the chair is connected to the elongate support member by releasable locking means.
Claim 10
Dependent Claim
34 words
An apparatus as set forth in claim 1, further comprising an additional housing which is releasably secured to the said housing and which contains electronic means for processing the measurements obtained by said detector.
