Special camera detects tumors
Date:11/7/2013

This news release is available in German.

Cancer patients have the highest probability of recovering if tumors are completely removed. However, tiny clusters of cancer cells are often difficult for surgeons to recognize and remove. A camera makes hidden tumors visible during an operation.

Tumor removal surgeries pose a great challenge even to skillful and experienced surgeons. For one thing, tumor margins are blending into healthy tissue and are difficult to differentiate. For another, distributed domains of cancer and pre-malignancies are difficult to recognize. Up to now, doctors depend exclusively upon their trained eyes when excising pieces of tumors. In future, a new special camera system can help visualize during operation even the smallest, easy-to-overlook malignant pieces of tumor and thereby support the surgeons during complicated inter- ventions.

The trick: the camera can display fluorescent molecules that "paint" the cancer tissue. These are injected into the patients blood circulation prior to the operation and selectively attach onto the tumor during their trip through the body. If the corresponding area is then illumimated with a specific wavelength, fluorescence is emitted and the malignant tissue glows green, blue, red, or any other color, depending on the injected dye, while the healthy tissue appears the same. In this way, the surgeon can see clasters of tumors cells that cannot be recognized by the naked eye.

New system reveals several dyes simultaneously

Researchers at the Fraunhofer Project Group for Automation in Medicine and Biotechnology (PAMB), which belongs to the Fraunhofer Institute for Manufacturing Engineering and Auto- mation (IPA), have developed a new surgical aid, a multispectral fluorescence camera syste
