A computer system receives two dimensional slice data of a heart or other organ to be simulated in three dimensions. It also receives chemical composition data of the heart or other organ, and chemical composition data other parts of the body. These data are put in the computer memory. Then a Voxel View or three dimensional volume rendering program forms images of the organ to be studied. For example, with the heart it generates images of the atria and ventricle. Diagnostic data obtained from a patient conveniently with electrical measurement signals including an electrocardiagram, electromyogram, electroencephalogram, and other diagnostic measured electrical signals obtained from a patient are fed into the system and are placed in computer memory. Physiological data of the patient, including the strength, weakness and other parameters of the organ is also considered diagnostic data and is supplied into the system. This can be done manually with a keyboard or mouse, or may be supplied from a hard disk, a floppy disk or a tape. This is also fed into memory and is used to modify the three dimensional image data of the organ. This data is then synchronized with the electrical signal diagnostic data. Conveniently the first derivative of the electrical data signal is taken, and P and Q waves determined from the derivative. From this information the organ, including sub-parts, may be simulated. This data may be fed in black and white or preferably in color to a device which shows the organ for visualization, operation simulation, or training.
