Photoacoustic microscopy and computed tomography

Biomedical Optics, 2008
A pulsed laser produces a rapid small temperature rise in biological tissue, which leads to emission of ultrasonic waves due to thermoelastic expansion. The short-wavelength ultrasonic waves are then detected to form high-resolution tomographic images.

The influences of finite aperture size in photoacoustic computed tomography

Ultrasonics, 2023
In photoacoustic computed tomography (PACT), the "finite aperture effect" is often characterized as a tangential resolution that increases proportionally with the distance from the rotation center. However, this conclusion is based on the inaccurate point-detector assumption used in image reconstruction.
