Hitachi & Redlen Technologies announce agreement on joint development

Hitachi has been focusing on the healthcare field as one of the Social Innovation Business and has extensive expertise in healthcare total solutions which include medical diagnostic and clinical devices such as CT, MRI, particle beam therapy systems and also informatics including medical service and platform.

Redlen is a leading manufacturer of high resolution Cadmium Zinc Telluride (CZT) semiconductor radiation detectors which are used in the fields of medical imaging, security and nondestructive testing. Under this agreement, Hitachi and Redlen will collaborate to 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 which 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 which 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 gen 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 which fully utilises the performance of this new sensor technology.

Mr. Glenn Bindley, President & CEO, Redlen commented on the agreement, "We are excited to partner with Hitachi, one of the original pioneers of medical CT technology, to pursue the enormous potential for advancement in medical CT that photon counting semiconductor sensors offer."

"PCCT is a promising next generation device which achieves radiation exposure reduction, high functionality and high degree of precision. It is expected to broaden the field of application. I hope this agreement will provide opportunities for us to further contribute to healthcare innovation." commented Masaya Watanabe, Vice President and Executive Officer, President & CEO of Healthcare Group and Healthcare Company at Hitachi.

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