Photon Counting
Detector Technology

When a confident diagnosis is timely and critical, the OmniTom® Elite Photon Counting mobile CT scanner advances your standard of care in a single scan.

Utilizing NeuroLogica’s proprietary detector technology, the OmniTom Elite Photon Counting Detector (PCD) CT can directly measure the energy of incident x-ray photons as an electric charge cloud relevant to the x-ray photon attenuation coefficient of tissue through which the x-rays have passed.   

A photon counting detector (PCD) captures the X-ray photon directly at the detector and directly converts the energy to electrical signals. This is different than conventional energy integrating detector (EID) in current CT scanners, which converts the photons to light and then electrical signals.

This new technology can enable clinicians to make a more confident diagnosis due to the improved clinical information.  Conventional energy integrating detectors provide average attenuation coefficients, whereas photon counting detectors measure energy-dependent attenuation characteristics and then provide compositional information for individual materials in the body.

The NeuroLogica mobile CT scanner was designed to bring imaging closer to the bedside in order to reduce risks associated with transporting critically ill patients to the CT suite. The scanner can be moved around the hospital from one room to another, or an ER or operating room for intra-operative imaging. EID versions of this scanner are commonly used in ICUs to monitor the daily status of critical patients. Several mobile stroke units equipped with NeuroLogica's  CereTom or OmniTom head CT scanners are also currently in use to improve the treatment of stroke patients worldwide.  The OmniTom also accommodates neonate and pediatric scanning*. 

The mobile PCD-CT was built by combining two key technologies for the first time: portability and photon counting.
