Medical imaging refers to a range of techniques that aim to identify abnormalities very early on in the progress of a disease. Today, medical imaging procedures are essential in many specialties, from cardiology to oncology to psychiatry. New and innovative treatments that are targeted at the molecular level within the body are revolutionizing our understanding of, and approach to a range of diseases and conditions.

What were previously high-end imaging techniques only available at the largest medical centers, are now routine procedures. But there is an increasing demand for high-performance medical screening for cancer, Alzheimers and cardiac disease at a lower cost than is possible today.

SiPM sensors from SensL provide a high-performance alternative to the vacuum tube photomultiplier (PMT) used in PET and SPECT. The SiPM combines the good performance of the PMT with the practical advantages of a solid-state sensor. By replacing aging vacuum tubes with SiPM sensors, increased performance and practicality are available at a lower cost.

The key benefits of the SiPM are listed on the right, and below are links to further information on various medical imaging applications.

Benefits of the SiPM

  • Performance – With detection efficiencies of >50% at wavelengths that are well matched to commonly-used scintillators, SensL SiPM sensors deliver excellent performance.
  • Uniformity – The CMOS process used to create SensL SiPM sensors provides the highest uniformity of breakdown voltage and optical current.
  • Low bias voltage – ~30V operation greatly simplifies system design and increases patient safety where close contact with the human body is a requirement.
  • Compact and rugged – Allows close-packed arrays for high resolution imaging, or exceptionally compact intraoperative probes.
