The project ‘Elastography for faster recognition of breast cancer in 3D photoacoustic mammography’ expands the existing prototype of 3D photoacoustic mammography (the PAM3+ system) with elastography technology. With elastography, the breast is brought into light vibration in a controlled manner. Because the tumor is firmer than the surrounding tissue, the blood vessels around the harder tumor tissue will react differently to vibrations. Along with the 3D photoacoustic mammography, which uses harmless laser light and ultrasound to create 3D images of the blood vessel system in a breast, breast cancer can be detected faster and painlessly. This is essential for a rapid adoption of this globally unique, woman-friendly way of breast cancer diagnosis.
