Abstract
A scanner (A) generates electronic data which is indicative of characteristics of an interior region of a subject in an examination region. A computer generator (B) generates corresponding pixel values of first and second electronic image representations which are stored in first and second image memories (12, 22). A video processor 14 retrieves pixel values from one of the memories and converts them into a video signal for generating a visual display on a video monitor (16). An audio processor 24 retrieves values from the other image memory and utilizes them to control the frequencies and amplitudes or other characteristcs with which modulators (52, 54, 56, 58) modulate an audio icon signal. In this manner, the audio icon signal is modulated in accordance with the selected characteristics of the interior region. An electroacoustic transducer (66) converts the modulated audio signal into an audible display of the selected characteristic. The audio displayed selected characteristic might include flow rate, intensity, phase, relaxation values, diffusion coefficients, attenuation coefficients, acoustic impedance, flow velocities, photon counts, and a myriad of other parameters, both general and specific to the selected imaging modality.
