Prof. Yonina Eldar\u2019s lab at the Technion Faculty of Electrical Engineering has developed a new approach to ultrasound examinations. The lab has developed an advanced probe that eliminates the need for the large ultrasound devices that we know from clinics and hospitals. The probe acquires only the relevant data, which is transmitted to a remote processing unit or cloud. The resulting image is then transferred to the treating physician\u2019s smartphone (or tablet). Dr. Shai Tejman-Yarden, a cardiologist at Sheba Medical Center, explains that in the case of injuries, for example, \u201cThe development will provide a doctor who is not at the scene with information in real time, enabling him to instruct the paramedic at the scene. This development will also enable remote treatment for patients in developing countries, under the guidance of Israeli doctors.\u201d <\/span><\/p>\n Ultrasound \u00a0imaging is one of the world\u2019s most common medical tests. Its advantages: it is non-invasive, does not involve exposure to ionizing radiation, is risk-free and relatively inexpensive. Ultrasound is based on high-frequency sound waves that we cannot hear. During the examination, a probe that transmits sound waves is placed against the patient\u2019s body, and an image of the organs being scanned is created based on the pattern of the waves reflected back to the probe. This technology is used in a wide variety of important medical tests: assessing the condition of the fetus in utero, examining the baby\u2019s brain through the fontanel (the gap between the bones of the skull), diagnosing conditions of the internal organs, evaluating blood flow, diagnosing thyroid problems, cardiac examinations, detecting tumors and infections, and more. <\/span><\/p>\n At present, ultrasound examinations are performed at clinics and hospitals using a probe connected to a large, cumbersome and expensive ultrasound device. The results of the scan are collected in the computer and interpreted by a radiologist, who sends the diagnosis to the patient\u2019s doctor (generally the family doctor). This process takes several days, which could be critical in some cases. <\/span><\/p>\n Uploading the scan results to a cloud and enabling the patient\u2019s doctor to view the findings on his mobile device could save time, but until now this has been avoided due to the large quantity of data acquired in each ultrasound scan. In addition, because of the device\u2019s high data acquisition rate, the probe must be connected to it by means of a thick, heavy cable.<\/span><\/p>\n The good news is that the SAMPL Lab at the Technion Faculty of Electrical Engineering, headed by Prof. Yonina Eldar, has developed a system that dramatically changes the nature of ultrasound examinations. \u00a0First, with the new algorithm developed at the lab, the data can be reduced at the initial scanning stage, so that it can be uploaded to a cloud without harming image quality and without loss of data on the way. Second, the innovative probe developed at the lab eliminates the need for the large ultrasound devices currently used at most clinics. <\/span><\/p>\n Prof. Yonina Eldar\u2019s lab is dedicated mainly to developing innovative data processing methods using only a small portion of the data sampled. Reducing the quantity of data sampled has very dramatic positive implications: shortening the data acquisition and processing time, miniaturizing the systems and accelerating their operation, reducing power consumption and saving money. The idea here is of course finding ways to reconstruct the preliminary data even though it is not transferred in full in this process. This is what the researchers at the lab are working on, and now, as stated, they have recorded a dramatic achievement in the field of ultrasound imaging. <\/span><\/p>\n Link to the full article \u2013 click here<\/a><\/strong><\/p>\n<\/a>
