Display of image data information

Abstract

A method is shown of producing a combined image comprising information from a first diagnostic image and a second diagnostic image, where areas of increased uptake are identified in the second diagnostic image and the areas of increased uptake in second diagnostic image are mapped onto the equivalent areas in the first diagnostic image. The areas of increased uptake in the second diagnostic image are identified as being those areas containing pixels whose intensity values are at least a threshold value, this value being calculated by: computing a histogram of the pixel values defined by the region of interest, showing a first significant peak of intensity values, applying a low pass filter, calculating the intensity value of the first significant peak, calculating a deviation value for the first significant peak, calculating a threshold value as a function of the intensity value of the first significant peak and the deviation value.
