Hitachi Medical Corp., a subsidiary of Hitachi Ltd. and Redlen Technologies Inc., have collaborated to develop a direct conversion semiconductor x-ray detector module needed for next-gen photon counting computed tomography systems (PCCT).

Under this agreement, Hitachi and Redlen will develop a multi-energy PCCT semiconductor detector module. PCCT systems offer the potential for a breakthrough advance in CT diagnostic imaging performance through new capabilities that include material discrimination, higher image resolution, the addition of functional imaging and further radiation dose reduction.

Current commercial CT systems have limited to no knowledge of individual photon energies. Redlen has successfully developed semiconductor radiation sensors that have the ability to measure the unique energy of individual x-ray photons while operating at the very high count rates and stability levels necessary for x-ray computed tomography. The additional information provided by these advanced radiation sensors is a key to realising next generation PCCT advances.

Hitachi and Redlen will jointly develop the data acquisition technology required to process the order of magnitude higher amount of data received from these semiconductor radiation sensors and the packaging technology necessary for assembling the sensors into a detector module. Exclusive use of the co-developed modules will enable Hitachi to develop an advanced PCCT that fully uses the performance of this sensor technology.

Hitachi and Redlen will work closely to accelerate the joint development for the detector modules. Hitachi will investigate a range of new diagnostic applications for PCCT based on the clinical evaluations planned both domestically and internationally.
