Description

Researchers at the Indian Institute of Technology (IIT) Madras have devised a new technology that uses a reconstructed ultrasound image to deliver a clear and high-quality visualisation. The findings could lead to improved illness diagnosis, identification of minute anomalies, and real-time image-guided biopsy and therapy monitoring applications. The method of ultrasonography is used to obtain real-time images inside the human body.

It has a wide range of practical uses in medical diagnosis and treatment. The method is commonly used to determine the origin of pain, edoema, and infection in internal organs, as well as to inspect a pregnant woman's foetus. An ultrasound machine's key component is a "beamformer," which has a significant impact on the quality of the reconstructed image. Several approaches for improving the quality of the reconstructed image by modifying the beamformer have been identified over the years.

The team claims to have created a novel beamforming technology that outperforms previous techniques and provides the best image resolution throughout the whole field of view. Their research findings were published in the peer-reviewed journal Scientific Reports.

"This research could potentially facilitate several applications such as early detection and better diagnosis of diseases, detection of minute abnormalities within the human body such as renal stones, better real-time image-guided biopsy procedures, and treatment monitoring applications," said Arun K Thittai, Professor, Department of Applied Mechanics, IIT Madras. Due to its ease of hardware implementation, the Delay and Sum (DAS) beamformer is the most often utilised ultrasonic imaging technology in commercial systems.
