Abstract

The core idea of the spectracoustic technique is the development and fabrication of a common probe for two modalities, the infrared spectroscopy and ultrasonic μTomography, for its application as a non-invasive analysis technique for tissue classification. The acquired and fused data from both modalities, provide a spectroscopic mapping tomographic image. The probe permits the excitation of the under-study object using both techniques simultaneously or in serial mode. Through the ultrasonic transducer of the probe, ultrasonic wave pulses are transmitted in the under-study tissue. Parallel to the path, used for the excitation of the piezoelectric transducer, a fiber optic bundle path is also designed in order to illuminate the under-study tissue. The reflected waves are transmitted back through the fiber optic bundle. The path used for emitting both the ultrasonics and infrared waves is filled with a special gel material in order for the ultrasonic probe to be coupled with the tissue. The infrared spectrum of this material is used as background spectrum form the infrared modality in order to be corrected from the acquired spectrum. By scanning a tissue in a specific region of interest, the incrementation of tomographic and spectroscopic data is achieved.
