ABSTRACT:
A method of imaging a characteristic of image intensity of an imaging agent in a subject consists of introducing the imaging agent into the subject and repetitively scanning the subject at each of a plurality of time intervals, so as to produce a plurality of time-sequenced images throughout the subject. Each of the time-sequenced images is then subdivided into a notional array of image elements such that there is a one-to-one correspondence between positions of image elements in the array and locations in the subject. Thereafter, a value of image intensity of the imaging agent at the corresponding location in the subject is determined for each image element in each of the time-sequenced images, the image elements in the arrays of successive time-sequenced images being in register with each other with respect to the locations. The determined image intensity values of image elements of plural time-sequenced images, in register with each other, are then combined to generate an image of the characteristic of image intensity of the imaging agent.
