Image Enhancement Software and Hardware Approaches

In this chapter we describe a series of software approaches including dual meshing, adjoint sensitivity, total variation minimization, radiative transfer equation, and parallel computation to enhance photoacoustic tomography (PAT) performance. These software approaches aim to improve image reconstruction in terms of forward and inverse solution accuracy, reduced noise effect, and computation speed. We also present several hardware approaches to improve the signal-to-noise ratio (SNR) of ultrasound transducer for improved PAT performance.
