Photoacoustic imaging is an imaging modality related to ultrasound imaging. A light source is inserted into a hollow-core needle and used to illuminate the patient’s tissues. The tissue expands, resulting in pressure waves, which are received by an ultrasound probe and then converted into human-interpretable images using a process called beamforming.
