- Abstract
Microwave induced thermoacoustic tomography (MI-TAT) combines the advantages of microwave imaging and ultrasound imaging to obtain high-resolution and high-contrast biological tissue microwave energy absorption images. However, the current MI-TAT technique often gets images with a large number of artifacts or error results in the case of small number of sensors and limited detection angle. In this paper, we first introduction the total variation minimization (TVM) in the field of finite element method (FEM) based MI-TAT reconstruction algorithm and we can get perfect thermoacoustic image reconstruction with a small number of detectors and limited-angles. Since this approach is extremely computationally demanding, we apply the parallel strategy using a multi-core graphic-processing-unit (GPU) card to accelerate the calculation. The improved algorithm is verified and evaluated through simulations and phantom experiments, and the results suggest that our new method holds great potential in various clinical studies in the future.
