Abstract

A measurement device includes: a processing device and multiple sensors that capture tomographic information of a physiological structure. The sensors include a first sensor including a first transducer having a first frequency response with a first resonant frequency, and a second sensor including a second transducer having a second frequency response with a second resonant frequency different from the first resonant frequency. The first frequency response partially overlaps with the second frequency response. The second transducer transmits a signal that is reflected by the physiological structure to create a reflected signal, the first transducer generates a first received signal from the reflected signal, the second transducer generates a second received signal from the reflected signal, and the processing device normalizes the first received signal with the second received signal or the second received signal with the first received signal.
