Photoacoustic tomography (PAT) is a promising imaging technique that can visualize the distribution of chromophores within biological tissue. However, the accuracy of PAT imaging is compromised by light fluence (LF), which hinders the quantification of light absorbers. Currently, model-based iterative methods are used for LF correction, but they require extensive computational resources due to repeated

Compensating unknown speed of sound in learned fast 3D limited-view photoacoustic tomography Photoacoustics (IF 7.9) Pub Date : 2024-02-17 Jenni Poimala, Ben Cox, Andreas Hauptmann
Real-time applications in three-dimensional photoacoustic tomography from planar sensors rely on fast reconstruction algorithms that assume the speed of sound (SoS) in the tissue is homogeneous. Moreover, the reconstruction quality depends on the correct choice for the constant SoS. In this study, we discuss the possibility of ameliorating the problem of unknown or heterogeneous SoS distributions by

Pre-transplant kidney quality evaluation using photoacoustic imaging during normothermic machine perfusion Photoacoustics (IF 7.9) Pub Date : 2024-02-09 Anton V. Nikolaev, Yitian Fang, Jeroen Essers, Kranthi M. Panth, Gisela Ambagtsheer, Marian C. Clahsen-van Groningen, Robert C. Minnee, Gijs van Soest, Ron W.F. de Bruin
Due to the shortage of kidneys donated for transplantation, surgeons are forced to use the organs with an elevated risk of poor function or even failure. Although the existing methods for pre-transplant quality evaluation have been validated over decades in population cohort studies across the world, new methods are needed as long as delayed graft function or failure in a kidney transplant occurs.
