Abstract
Abstract An isotope scanner is provided with an infrared capability by attaching an infrared radiometer on the scintillation probe containing the scintillation detector and using the scanning system of the isotope scanner to simultaneously scan the patient with the radiometer and the scintillation detector. The display equipment of the isotope scanner is utilized simultaneously by the isotope detector and the radiometer to provide a simultaneous infrared and isotope display of the patient under study. The isotope scanner and the infrared radiometer may also be used independently of each other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
A combination infrared and isotope scanner comprising in combination a. an isotope scanner having a scintillation detector which is scanned over a predetermined area of a patient under examination, b. multiple display means, c. electronic circuit means coupled to said scintillation detector and said multiple display means for processing the signals generated by said scintillation detector in response to radioactive isotope distribution in the patient under examination and driving at least one of said multiple display means to visually display the isotope concentration in the patient, d. an infrared radiometer mounted on said scintillation detector for scanning movement therewith such that said radiometer scans the same area as the scintillation detector, e. interface means coupled to said radiometer for converting the output of said radiometer for driving at least one of said multiple display means, and f. switch means for coupling said interface to at least one of said display means whereby simultaneously infrared and isotope scans of the patient may be visually displayed.
Claim 2
Dependent Claim
164 words
A combination infrared and isotope scanner comprising in combination a. an isotope scanner having a scintillation detector which is scanned over a predetermined area of a patient under examination, b. multiple display means, c. electronic circuit means coupled to said scintillation detector and said multiple display means for processing the signals generated by said scintillation detector in response to radioactive isotope distribution in the patient under examination and driving at least one of said multiple display means to visually display the isotope concentration in the patient, d. an infrared radiometer mounted on said scintillation detector for scanning movement therewith such that said radiometer scans the same area as the scintillation detector, e. interface means coupled to said radiometer for converting the output of said radiometer for driving at least one of said multiple display means, and f. switch means for coupling said interface to at least one of said display means whereby simultaneously infrared and isotope scans of the patient may be visually displayed.
Claim 3
Dependent Claim
31 words
The combined infrared and isotope scanner set forth in claim 1 including means for bore-sighting said scintillation detector and said infrared radiometer whereby identical points may be scanned and displayed simultaneously.
Claim 4
Dependent Claim
38 words
The combined infrared and isotope scanner set forth in claim 1 wherein said interface means includes amplifier means to which said radiometer is coupled by a sensitivity control means, said amplifier means also having a brightness control means.
Claim 5
Dependent Claim
48 words
The combined infrared and isotope scanner set forth in claim 1 wherein one of said multiple display means comprises a color dot recorder, a tap rate oscillator in said interface, said tap rate oscillator being capable of being connected to said color dot recorder via said switch means.
