Medical Imaging

Looking inside the body for early detection and treatment of disease.

The goal of medical imaging is to provide diagnostic information which is invisible to the human eye or comes from within the body. It allows the medical doctor an accurate diagnosis with non-invasive methods. Many of these techniques demand for sensor technologies which are fast, have a high sensitivity and are reliable also in long term usage. The performance of a medical imaging device is already defined on detector level by the detector’s quality. There is an increasing demand for sensors which detect in the visible light regime, either for direct detection of photons or for the use in combination with a scintillator.

KETEK SiPMs provide excellent performance for these detection tasks and are the superior alternative compared to the traditionally used light detectors like PMTs (photomultiplier tubes) and APDs (avalanche photodiodes). Our SiPMs are still able to work under adhere circumstances like e.g. high magnetic fields or electromagnetic polluted environments without compromising the performance. KETEK SiPMs operate at a low voltage of about 30 V increasing the operation safety. As a result, employing this faster and more sensitive detection techniques there is a direct impact on the image quality. This can help to increase the accurracy of a diagnosis and the further treatment, ensuring the health of the individual. SiPMs from KETEK provide superior performance at a lower cost for these tasks.
