New Delhi: Researchers from the Indian Institute of Technology (IIT), Madras have recently developed a new technique that can deliver clear and high-quality visualisation through reconstructed ultrasound images of High-resolution.
This research can be beneficial for detection of abnormalities, diagnosis of diseases & better real-time image-guided biopsy procedures and treatment monitoring applications.
The technique of Ultrasound imaging is used to capture real-time Images of the Human body from inside, which has a wide range of clinical applications in different types of diagnosis & treatment of medical conditions. It is used to diagnose the cause of swelling, pain and infection in internal organs and to also examine the foetuses in pregnant women.
The Main component of an Ultrasound machine is a "beamformer", as it plays a prominent role in the final image quality. Over the years, IIT Madras researchers have identified several techniques to improve reconstructed image quality by changing beamformers.
Delay and Sum (DAS) beamformer is the most used ultrasound imaging technique in commercial systems due to its simplicity of hardware implementation. However, it has low image resolution.
IIT Madras researchers claimed that with advancements in computational capability an alternative beamformer based on Filtered Delay Multiply and Sum they have developed a new beamforming technique, F-DowMAS that can Improve both resolution and contrast of an Image simultaneously and parallelly it can also reduce the noise levels to a greater extent in the reconstructed image.The research findings have been published in a peer-reviewed Journal, Scientific Reports
Briefing about this research, Arun K Thittai, Professor, Department of Applied Mechanics, IIT Madras said,"This research could potentially facilitate applications like early detection & better diagnosis of diseases, detection of minute abnormalities within human body like renal stones, better real-time image-guided biopsy procedures & treatment monitoring applications."
"This enhancement will help clinicians notice minute changes in anatomy, which will help in early and better diagnosis of diseases. The developed technique can also be integrated to the already existing commercial Ultrasound scanner platforms without any need for additional hardware changes, which makes this solution both economical and feasible, '' said Anudeep Vayyeti, a Research scholar at IIT Madras.
