With ultrasound imaging, people can get real-time images inside their bodies, which uses sound waves to look inside the body. It can be used in many different ways to diagnose and treat medical problems in the field of medicine.
People who study ultrasound images have developed a new way to make them look like they were taken again. The Delay and Sum (DAS) beamformer is the most common ultrasound imaging method in commercial systems. F-DowMAS is a new technique that can improve both the resolution and contrast of an image simultaneously, making it clearer and brighter. Noise levels in the reconstructed image can also be lessened by this method than before.
- The Indian Institute of Technology (IIT) Madras has developed a new technique for visualizing reconstructed ultrasound pictures.
- The findings could lead to better illness identification, real-time image-guided biopsy procedures, and treatment monitoring applications.
- Due to its ease of hardware implementation, the Delay and Sum (DAS) beamformer is the most widely used ultrasound imaging technology.
- To compensate for the DAS’s shortcomings, a new beamformer based on the Filtered Delay Multiply and Sum (F-DMAS) approach was introduced recently.
- Several similar approaches are being developed in research institutes worldwide.
- The researchers claim that their F-DowMAS technique can simultaneously improve image resolution and contrast while reducing noise levels in the rebuilt image.
Researchers at the Indian Institute of Technology (IIT) Madras have come up with a new way to show ultrasound images that have been reconstructed. In the future, this research could help doctors better diagnose diseases and find small abnormalities and better real-time imaging-guided biopsy procedures and treatment monitoring apps.
An ultrasound imaging method is used to get real-time images inside the body. It can be used in many different ways to diagnose and treat medical problems. Many people use this method when they have problems with their internal organs or are pregnant. It is also used to look at fetuses in pregnant women.
Beamforming is the main part of an ultrasound machine, and it has a big impact on how well the image looks when it’s done. Over the years, many ways have been found to improve the quality of the reconstructed image by changing the beamformer, which is how the image is shown.
The team says they’ve come up with a new beamforming technique that is better than other techniques and gives the best picture resolution across the field of view. In the journal Scientific Reports, they have written about the results of their research.
Early detection and better diagnosis of diseases could benefit from this research and better real-time imaging-guided biopsy procedures and treatment monitoring applications. “Arun K. Thittai,” Professor of Applied Mechanics at IT Madras, told PTI that this research could be used for a wide range of things.
The Delay and Sum (DAS) beamformer is the most common type of ultrasound imaging in commercial systems because it is easy to set up in hardware. However, the picture quality isn’t very good. The Filtered Delay Multiply and Sum (F-DMAS) technique was used to make up for some of the DAS’s flaws. This beamformer was used to make up for the DAS’s flaws.
People around the world are working on new ways to do this. Many of the existing techniques had many problems, like low noise rejection, which means that more noise is added to the images, which is a problem because these existing techniques have a multiplicative effect. “Low contrast to noise ratio,” said Anudeep Vayyeti, a research scholar at IIT Madras. Even though these techniques can improve resolution, they also make the images less clear.
In this way, it’s hard to see small changes in the underlying tissue in the image taken, which can help with the early detection of the disease. There is a new technique called Filtered Delay optimally-weighted Multiply and Sum (F-DowMAS) that we have developed that will give us better images than the ones already out there. Using the F-DowMAS method, researchers say that they can improve both the resolution and contrast of images simultaneously. At the same time, it can also reduce noise levels in the reconstructed image. People who work with people’s bodies, like doctors, will see even the smallest changes in their anatomy, which will help them make better diagnoses early on. “Also, the new technique can be easily added to commercial ultrasound scanners without having to make any changes to the hardware, which makes this a cheap and practical solution.”
