Spectral crosstalk in photoacoustic computed tomography [PDF]
Multispectral photoacoustic (PA) imaging faces two major challenges: the spectral coloring effect, which has been studied extensively as an optical inversion problem, and the spectral crosstalk, which is basically a result of non-ideal acoustic inversion.

Adaptive polarization photoacoustic computed tomography for biological anisotropic tissue imaging [PDF]
Most photoacoustic computed tomography (PACT) systems usually ignore the anisotropy of the tissue absorption coefficient, which will lead to the lack of information in reconstructed images.

Adaptive photoacoustic computed tomography [PDF]
For many optical imaging modalities, image qualities are inevitably degraded by wavefront distortions caused by varying light speed. In optical microscopy and astronomy, adaptive optics (AO) has long been applied to compensate for such unwanted ...

Adaptive dual-speed ultrasound and photoacoustic computed tomography [PDF]
Full-ring dual-modal ultrasound and photoacoustic computed tomography has unique advantages of nearly isotropic spatial resolution, complementary contrast, deep penetration, and full-view detection. However, the imaging quality may be deteriorated by the

Ultrasound-guided sound speed correction for photoacoustic computed tomography [PDF]
Photoacoustic computed tomography (PACT) reconstructs high-resolution images of various chromophores in deep biological tissue. A key to high-quality reconstruction is accurate compensation for the spatially heterogeneous speed of sound (SoS) in tissue ...

PATLAB: A graphical computational software package for photoacoustic computed tomography research [PDF]
Photoacoustic tomography (PAT) provides high resolution optical images of tissue at depths of up to several centimetres. This modality has been of interest to researchers for at least 30 years and is still the subject of intensive research.

Application of photoacoustic computed tomography in biomedical imaging: A literature review [PDF]
Photoacoustic computed tomography (PACT) is a hybrid imaging modality that combines optical excitation and acoustic detection techniques. It obtains high‐resolution deep‐tissue images based on the deep penetration of light, the anisotropy of light ...

Single-breath-hold photoacoustic computed tomography of the breast [PDF]
The current standard for breast cancer diagnostic is a mammogram; however, the sensitivity of mammography can be low in radiographically dense breasts. Here the authors develop a single-breath-hold photoacoustic computed tomography (SBH-PACT) system to ...

Location-Dependent Spatiotemporal Antialiasing in Photoacoustic Computed Tomography. [PDF]
Photoacoustic computed tomography (PACT) images optical absorption contrast by detecting ultrasonic waves induced by optical energy deposition in materials such as biological tissues. An ultrasonic transducer array or its scanning equivalent is used to detect ultrasonic waves. The spatial distribution of the transducer elements must satisfy the spatial
