Key result
The GMR sensor-based GastroSmart system successfully estimated gastric volume changes under various dietary conditions, though measurements were generally lower than those obtained via traditional ultrasonic imaging.
Why the study?
Pathological gastroenterological conditions present major health risks, but conventional imaging methods such as ultrasound are costly and lack real-time monitoring capabilities.
Does a GMR sensor-based system accurately measure gastric volume compared to conventional ultrasonic imaging in human subjects?

A novel GMR sensor-based system provides a non-invasive, low-cost alternative to ultrasonic imaging for continuous gastric volume monitoring.
Offers a non-invasive, proof-of-concept tool for real-time gastric monitoring;.
Pathological conditions affecting the gastroenterological tract such as GERD, gastroparesis, gastric cancer, type 2 diabetes, and obesity among others present alarming levels of health risks. Conventional imaging methods such as ultrasonic imaging have a very high cost and do not provide real-time monitoring. To overcome these challenges, we present a new system based on GMR sensor capable of non-invasively measuring gastric volume over prolonged periods of time. This system uses Rational Dilation Wavelet Transformation in order to enhance the accuracy of the evaluated gastric dynamics. With the help of polynomial regression, gastric volume changes can be predicted very accurately by our model, which makes it possible to prevent exacerbation of gastrointestinal diseases in early stages. The continuous evaluation of the condition of the patients and their physical activity performed by this non-invasive method will allow individualized treatment to each patient in the best possible way and will improve healing without sacrificing safety. This investigation is a response for implementing low-cost and effective solutions for constant monitoring of patients with gastrointestinal distresses in the direction of preventive nursing and clinical care for patients.

Dhakshunaamoorthiy et al. (2024) studied Healthy volunteers (gastric volume monitoring) (n=2). GMR sensor-based gastric volume measurement (GastroSmart) vs. Ultrasonic imaging was evaluated on Gastric volume measurement. The GMR sensor-based GastroSmart system successfully estimated gastric volume changes under various dietary conditions, though measurements were generally lower than those obtained via traditional ultrasonic imaging.
