Description/Abstract:
A NEW WHOLE-BODY COUNTER IS DESCRIBED THAT PROVIDES A METHOD FOR THE DETERMINATION OF THE AMOUNT AND DISTRIBUTION OF RADIONUCLIDES IN THE HUMAN BODY. THE MEASUREMENT IS TAKEN WITH THE HUMAN SUBJECT ROTATING ON A POWER-DRIVEN TURNTABLE WHILE THE SCINTILLATION DETECTORS MOVE DOWN THE LONGITUDINAL AXIS OF THE ROTATING BODY. THE LOCATION OF THE RADIOACTIVE SOURCE IS INDICATED BY AN INCREASED COUNTING RATE AT POINTS ALONG AN IMAGINARY HELIX WHICH SURROUNDS THE BODY. COUNTING RATE, LINEAR DISTANCE OF THE DETECTOR DOWN THE BODY FROM A REFERENCE POINT, AND BODY ORIENTATION WITH RESPECT TO THE DETECTOR ARE THE THREE VARIABLES FOR DEFINING THE POSITION OF ACTIVITY. THIS TECHNIQUE OF COUNTING IS ESPECIALLY APPLICABLE FOR THE IN VIVO DETERMINATION OF RADIONUCLIDES IN THE HUMAN SUBJECTS BECAUSE BOTH THE BODY RADIOACTIVITY AND APPROXIMATE DISTRIBUTION CAN BE DETERMINED SIMULTANEOUSLY. THE PROCEDURE CAN BE USED FOR ANY TYPE OF SOLID SAMPLES THAT CONTAIN AN UNKNOWN DISTRIBUTION OF ACTIVITY.
