Diagnosis based on remote ultrasound will soon be available

June 6, 2011 By Cécilia Carron

An ultrasound machine has been transformed into a telediagnosis tool. Specialists in other hospitals can see images in real time, pinpoint the exact zone they’re coming from, and interact.

Making a diagnosis using ultrasound often requires advice from experts in other hospitals, particularly in neurology. Sonography is one of the most commonly used imaging techniques. But to make an interpretation, a doctor must have access to the and know exactly where the is placed on the patient. This has been an obstacle to remote diagnostics, one that will soon be overcome. A remote , developed by French-Swiss teams of researchers and two start-up companies, allows the specialist see the image taken by the transducer as well as its position, all in . The doctor can also indicate the exact area that he or she would like to see with the cursor. The technician who is with the patient then moves the transducer.

This equipment, developed by a team led by Professor Jean-Philippe Thiran from EPFL’s Signal Processing Laboratory, has been adapted to work on traditional ultrasound machines. A small motion detector the size of a cherry is attached underneath the transducer. A optical feedback system consisting of two infrared cameras, developed by Atracsys, an EPFL start-up headquartered in Le Mont-sur-Lausanne, films the transducer, and a software program displays it in color on a virtual human on the screen. The corresponding ultrasound images are displayed in parallel. The specialist can thus interact with the image and ask the on-site team to move the transducer to precise points. Using software developed by Thiran’s team, the specialist indicates the zone to observe on the patient with a movement of the mouse. Already tested at the Lausanne University (CHUV) and the CHU in Besançon, the device has been integrated into a telediagnosis platform being developed by Covalia, a project partner company based in Besançon, and will be commercially available within a few months.

“Medical imaging is currently very quantitatively oriented, for example, to highlight brain structures, and measure and compare them,” explains Thiran. The same research team has developed another remote diagnosis tool, a server for analyzing medical imaging data. The images are sent securely via a network and can be analyzed in various ways – by slice, in 3D, with color contrast, etc. Doctors who are tens of kilometers away from each other can share the images and discuss results.
