Image guided filtering for improving photoacoustic tomographic image reconstruction
Several algorithms exist to solve the photoacoustic image reconstruction problem depending on the expected reconstructed image features. These reconstruction algorithms promote typically one feature, such as being smooth ...
Vector extrapolation methods for accelerating iterative reconstruction methods in limited-data photoacoustic tomography
As limited data photoacoustic tomographic image reconstruction problem is known to be ill-posed, the iterative reconstruction methods were proven to be effective in terms of providing good quality initial pressure distribution. ...
Accelerated image reconstruction using extrapolated Tikhonov filtering for photoacoustic tomography
Purpose: Development of simple and computationally efficient extrapolated Tikhonov filtering reconstruction methods for photoacoustic tomography. Methods: The model-based reconstruction algorithms in photoacoustic tomography ...
High-speed, low-cost, pulsed laser diode based second generation desktop photoacoustic tomography system
Bulky, expensive Nd:YAG lasers are used in conventional photoacoustic tomography (PAT) systems making them difficult to translate into clinics. Moreover, real-time imaging is not feasible when single-element ultrasound ...
