Paper Abstract

Ultrasound modulated optical tomography, a combination of optical and acoustic technology, has become a noninvasive biomedical tomography with promising future. However for long days its spatial resolution was always limited by ultrasound waist size. In this paper a new method using deconvolution algorithm was suggested to solve this problem. Ultrasound modulated optical signals were processed by deconvolution algorithm before they are used for image reconstruction. Both theory analysis and numerical calculation results have shown that the spatial resolution could be greatly improved and image quality became better. This method requires no modification of optical geometry and detection system, only appropriate mathematical processing was needed. It is believed to be a simple, practical and effective way in realizing super resolution in ultrasound modulated optical tomography.
