METHOD AND APPARATUS FOR PRODUCING A REPRESENTATION OF A MEASURABLE PROPERTY WHICH VARIES IN TIME AND SPACE, FOR PRODUCING AN IMAGE REPRESENTING CHANGES IN RADIOACTIVITY IN AN OBJECT AND FOR ANALYZING TOMOGRAPHY SCAN IMAGES

摘要

A method, apparatus, medium and signal for producing a representation of ameasurable property which varies in time and space are disclosed. Theapparatus includes a receiver for receiving a plurality of sets of valuesrepresenting measurements of the property across the object at respectivemeasurement times, each set being associated with a respectivemeasurement time. The apparatus further includes a processor circuit incommunication with the receiver. The processor circuit is programmed toproduce a plurality of sets of values representing the property at a pluralityoflocations throughout the object at the respective measurement times, byminimizing a figure of merit function relating the values representing themeasurements with the values representing the property at the plurality oflocations, with a shape constraint imposed on the values representing theproperty at the plurality of locations.
