BACKGROUND

PhotoAcoustic/ThermoAcoustic computed Tomography (PAT/TAT) is an emerging technique that promises cancer screening without ionizing radiation.

The tissue dilation induced by pulse laser illumination generates ultrasound waves that are detected by transducers. By using low scattered microwaves for excitation, PAT/TAT allows deep tissue imaging (several cm) with a good optical imaging resolution (below mm). However, current approaches require multiple acquisitions and downstream complex processing to locate targets, e.g. a tumors. MAMMOSCAN overcomes this issue through a smarter use of marginal signals, cf hereafter.

KEY BENEFITS vs. EXISTING

MAMMOSCAN definitely improves PAT/TAT through:

• ONE-SHOT localization of targets
• EASIER processing

enabling faster target localization and more accurate target qualification.

DEVELOPMENT STATUS

Simulation model validated

APPLICATIONS

• Medical imaging, e.g.breast cancer, angiology, dermatology
• Materials characterization, e.g. geology
