A team of Nigerian scientists has secured intellectual property protection in the United Kingdom for a home-grown medical imaging innovation that could improve the accuracy of diagnostic equipment used in hospitals, research laboratories and universities, marking another sign that Nigerian research is gaining global recognition despite longstanding local funding challenges.
The innovation, known as the Self-Calibrating Optical Imaging Photodetector, was registered by the United Kingdom Intellectual Property Office (UKIPO) under UK Design No. 6482043 on November 18, 2025. The device integrates sensing, imaging and automatic calibration into a single platform, reducing the need for repeated manual adjustments that often affect the quality and reliability of medical images.

The registered design was developed by Okechukwu Felix Erondu, Onuh Matthew Ijiga, Terver Sombo and Peverga Rex Jubu through an interdisciplinary collaboration combining expertise in radiography, applied physics, industrial physics and nano-optoelectronics.
The breakthrough comes as healthcare providers worldwide increasingly seek imaging technologies capable of delivering more accurate diagnoses with less human intervention. Calibration problems remain one of the biggest technical challenges in optical imaging systems, as even slight alignment errors can reduce image quality and produce inconsistent medical results.
Unlike conventional systems that rely on external calibration equipment or frequent manual adjustments, the Nigerian-designed device continuously aligns itself during operation through an integrated self-calibration mechanism. A built-in ALIGN indicator allows users to monitor and optimise optical alignment in real time, helping to maintain measurement accuracy while reducing workflow interruptions.
According to the researchers, the system combines an elevated optical sensing unit, a centrally positioned display and a multifunction control console into one platform, enabling operators to monitor imaging and calibration simultaneously. They believe the design can improve measurement repeatability while reducing optical drift in clinical and laboratory environments.
Potential applications include biomedical imaging, fluorescence diagnostics, microscopy, laboratory photometry and other scientific fields where precise optical measurements are critical.
Erondu, a professor of Radiography at Gregory University, Uturu, and founder and chief medical director of Image Diagnostics, Port Harcourt, said years of experience in diagnostic imaging inspired the innovation.
“My experience in diagnostic imaging has consistently shown that calibration drift and alignment inconsistencies compromise image reliability. This device integrates calibration directly into the imaging structure, reducing operator error and strengthening diagnostic confidence,” he said.
Onuh Matthew Ijiga, an applied physics researcher at Joseph Sarwuan Tarka University, Makurdi, said advances in semiconductor physics and nanomaterials helped improve the device’s optical sensitivity and signal stability.
The researchers said embedding calibration into the imaging architecture rather than treating it as a separate process distinguishes the invention from many existing systems and could improve the reliability of optical instruments used in healthcare, scientific research and industrial applications.
Beyond protecting the invention’s design, the UK registration highlights the growing international visibility of Nigerian scientific research and demonstrates how local researchers continue to produce globally relevant technologies despite limited research funding and commercialisation opportunities.
For Nigeria’s research community, the recognition offers further evidence that locally developed innovations can compete on the international stage while contributing practical solutions to global healthcare and scientific challenges.
