Signal and Image Processing Seminar

Tomographic imaging of tissue microvasculature will assist biomedical researchers and physicians in the diagnosis and treatment of a variety of diseases. The basic physical mechanisms relevant in two novel optical techniques for tomographic imaging of microvasculature use photothermal excitation and the coherent properties of light: these techniques are infrared tomographic microscopy and optical Doppler tomography. The basic principles underlying each tomographic method will be described and the multidimensional nature of associated signal processing problems indicated. Application of the tomographic imaging techniques to biomedical problems involving the microvasculature will be described.
