Single-breath-hold photoacoustic computed tomography of the breast [PDF]

Nature Communications, 2018
We have developed a single-breath-hold photoacoustic computed tomography (SBH-PACT) system to reveal detailed angiographic structures in human breasts. SBH-PACT features a deep penetration depth (4 cm in vivo) with high spatial and temporal resolutions ...
