Ingestible capsule X-ray dosimeter for real-time radiotherapy monitoring by Singapore

18 April 2023 | News

To benefit gastric cancer patients undergoing radiotherapy

A new invention by researchers from the National University of Singapore (NUS) could help improve the treatment of gastric cancer by enhancing the precision of radiotherapy, which is commonly used in combination with treatment options such as surgery, chemotherapy or immunotherapy.

In the field of modern radiotherapy, precision in targeting tumour tissue while minimising damage to healthy tissue is crucial. However, low efficacy and variable outcomes remain a challenge due to patient diversity, treatment uncertainty, and differences in delivery types. 

To address these limitations, Prof Liu and his team developed a novel ingestible X-ray dosimeter capsule capable of measuring the dose of radiation, and physiological changes in pH and temperature in real time during gastrointestinal radiotherapy.
