This could revolutionize healthcare by making ultrasound more accessible to people in under-resourced regions.</p> <p>However, capturing and interpreting ultrasound is a complex medical imaging technique that requires years of training and experience, and there is a shortage of trained ultrasonography experts in these regions. This has real repercussions. For example, up to 50% of pregnant people in low-resource settings do not receive ultrasound screenings during pregnancy. This can lead to delays in diagnosis and treatment of pregnancy complications, which can have serious consequences.</p> </div> </div> </div> </div> </div> </section><section class="g-h-block-style glue-mod-spacer-6-top glue-mod-spacer-4-bottom"> <div class="glue-page research-section"> <div class="g-h-content-block"> <div class="glue-grid content-block-grid"> <div class="glue-grid__col glue-grid__col--span-12-md glue-grid__col--align-middle glue-grid__col--span-6 glue-mod-order-1 glue-mod-order-2-md glue-mod-order-2-lg glue-mod-order-2-xl"> <div class="g-h-content-block__asset g-h-content-block__asset--reverse"> <picture> <source srcset="https://lh3.googleusercontent.com/iWwgQQfWH5PdQFY16hHVLvCRG7YgBd32d-VTYbVinWMTeTa59igoCTedm5ONBs4eXNwZLNDe0waibrLoTsQ73aAIijzSVhrhaNsha3_1Oj1a4GcYfwXu=w1000-l80-sg" media="(max-width:900px)"> <img src="https://lh3.googleusercontent.com/iWwgQQfWH5PdQFY16hHVLvCRG7YgBd32d-VTYbVinWMTeTa59igoCTedm5ONBs4eXNwZLNDe0waibrLoTsQ73aAIijzSVhrhaNsha3_1Oj1a4GcYfwXu=w0-e30-l80-sg" alt="some medical information with the accuracy of a skilled sonographer" loading="lazy"> </picture> </div> </div> <div class="g-h__desc-section glue-grid__col glue-grid__col--align-middle glue-grid__col--span-6 glue-grid__col--span-12-md glue-mod-order-2 glue-mod-order-1-md glue-mod-order-1-lg glue-mod-order-1-xl"> <div class="g-h-content-block__title glue-mod-spacer-3-bottom"> <h2 class="glue-headline glue-headline--headline-3">Our research shows that AI can identify some medical information with the accuracy of a skilled sonographer</h2> </div> <div class="g-h-content-block__text"> <p>We are building AI models to expand access to ultrasound, allowing individuals with no background in ultrasonography to collect clinically useful ultrasound scans.
