A special camera captures objects near and far.
Imaging is just as important in the early detection of breast cancer. But a mammogram is painful and, where breast tissue is thick, potentially unreliable.
Reason enough for a US-based research team to develop a pain-free method, allowing patients to press their breasts gently against a vertical pane from a standing position.
First, laser pulses heat light-sensitive molecules in the tissue, causing them to expand and making accumulated blood vessels easier to discern. Molecule expansion also creates ultrasound waves.
Converted by sensors, this second image highlights any potential damage. An algorithm clarifies the 3D images, enabling experts to distinguish between different types of breast cancer.
Another ultrasound system relies on bras.
