In some cases, patients are even required to hold their breath several times during the process.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But MRIs would be less of an ordeal with the \u201ccompressed sensing\u201d technology created by the researchers &#8212; <\/span><a href=\"http:\/\/richb.rice.edu\/biography\/\"><span style=\"font-weight: 400;\">R<\/span><span style=\"font-weight: 400;\">ichard Baraniuk<\/span><\/a><span style=\"font-weight: 400;\">, Rice\u2019s Victor E. Cameron Professor of Electrical and Computer Engineering, and <\/span><a href=\"https:\/\/www.ece.rice.edu\/kelly.aspx\"><span style=\"font-weight: 400;\">Kevin Kelly<\/span><\/a><span style=\"font-weight: 400;\">, a Rice associate professor of electrical and computer engineering &#8212; to <\/span><span style=\"font-weight: 400;\">help provide a solution for a clinical problem in the field of medical technology that revolved around reducing the lengthy time of MRI scans while still maintaining the best quality possible for a patient\u2019s diagnoses. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">This new technology requires less data to deliver the best quality diagnosis, thereby enabling a faster, more efficient process. This is chiefly due to the fact that doctors will be gleaning the information they need from far fewer data samples.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cMRI machines currently use mathematical technology developed in the 1930s, and scans can take up to 45 minutes and require patients to hold completely still during that time, something that is especially difficult for very sick or very young patients,\u201d Baraniuk said in a statement. \u201cThis technology will be a game-changer for MRI scanners, especially when it comes to serving patients whose age or health prevents them from holding their breath or being completely still for extended periods of time. The technology will also benefit cardiac patients. Previously, low diagnostic quality prevented these patient subsets from realizing any benefit from cardiac MRI, but the technology enables the entire cardiac cycle to be recorded in real time with only one breath-hold.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The technology has been licensed to German medical technology company Siemens Healthineers for use in cardiovascular imaging, which rolled out new MRI scanners using the \u201ccompressed sensing\u201d technology last year and received approval for clinical testing in February. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">These new MRI scanners can complete the scan of a beating heart in as few as 25 seconds<\/span><span style=\"font-weight: 400;\">, with patients breathing normally and holding their breath just once. In comparison, MRI scanners using current technology took four minutes or more to complete a scan of a beating heart with patients required to lie still during the process and hold their breath for seven to 12 times. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The researchers believe that the technology would make MRIs of the abdomen, which require \u201clong, consecutive and exhausting breath-holds,\u201d more available to patients who are currently excluded because they are either too young to comply with the arduous breath-hold requirement or have labored breathing.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The researchers also believe that their technology has other potential commercial use. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cWe can expect to see compressive sensing applications expanding beyond medical imaging (e.g., MRI and CT) and into other domains where acquiring data is expensive in either hardware or time, including cameras for infrared and hyperspectral imaging as well as radar and sonar,\u201d said <\/span><a href=\"http:\/\/news.rice.edu\/contact-us\/\"><span style=\"font-weight: 400;\">Amy McCaig<\/span><\/a><span style=\"font-weight: 400;\">, senior media relations specialist at Rice. \u201cGood progress has already been made in all of these areas; in some, commercial systems are just around the corner. Unlike digital cameras that see in the visible wavelengths, infrared camera systems are quite expensive and thus compressive imaging could greatly save on the cost of such systems.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cIt is great for us to see something go from basic research to real-world applications. In addition, this research field as a whole is constantly improving both the hardware implementations and reconstruction algorithms every day to further increase its potential utility.\u201d<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Two Rice University researchers have developed a new \u2018compressed sensing\u2019 technology that will benefit patients who are required to undergo magnetic resonance imaging (MRI) for diagnosis of their medical conditions.
