Ultrasound images, known as sonograms, have become a familiar partof pregnancy, allowing expectant parents a view of their unbornchild. But new research at Massachusetts Institute of Technology(MIT) could improve the ability of untrained workers to performbasic ultrasound tests, while allowing trained workers to much moreaccurately track the development of medical conditions, such as thegrowth of a tumor or the buildup of plaque in arteries. The improvements to this widely used technology could providedetailed information far beyond what is possible with existingsystems, the researchers say. The work, led by Brian W.
Anthony,co-director of MIT's Medical Electronic Device Realization Center(MEDRC) and director of the Master of Engineering in ManufacturingProgram, was recently presented at the International Symposium onBiomedical Imaging in Barcelona, Spain. There are two key elements to the improvements engineered byAnthony and his team. First, the researchers devised a way toadjust for variations in the force exerted by a sonographer,producing more consistent images that can compensate for bodymotions such as breathing and heartbeat. Second, they provided away to map the exact location on the skin where one reading wastaken, so that it can be precisely matched with later readings todetect changes in the size or location of a tumor, clot, or otherstructure.
Together, the two improvements could make sonography a much moreprecise tool for monitoring the progression of disease, Anthonysays. The devices are currently undergoing three clinical trials,including one at Boston Children's Hospital focused on monitoringthe progression of patients with Duchenne Muscular Dystrophy (DMD). In that trial, Anthony says, researchers are trying to determine"how fast the muscle deteriorates, and how effective differentmedications are." It's important to have a reliable way ofmonitoring changes in muscle, he says. The study is aimed atdetermining whether ultrasound analysis can serve as a convenient,noninvasive, clinically meaningful way of monitoring diseaseprogression in DMD.
The new device maintains constant force through the addition of aforce sensor to its probe tip and servomotors that can respondalmost instantly to changes in force. That, in turn, makes itpossible to analyze how the image varies as the force increases,which can provide important vag diagnostic tool information about theelasticity of skin, muscle, and other tissues. To provide accurate positioning, a tiny camera and lens mounted onthe probe can reveal skin patterns that are distinctive andconstant, similar to fingerprints. "Skin patterns are prettyunique," Anthony says; his team's system, using software to comparenew images with earlier ones, "can get you back to that same patchof skin," something that is impossible to do manually. Anthony likens that precise positioning to "an on-the-patient GPSsystem" for locating structures in the body.
The ability to takeimages over time from exactly the same position makes it possibleto monitor changing tissues quite precisely: The imaging system candetermine the volume of a near-surface tumor or other feature towithin an accuracy of 1% to 2%, he says. There are existing ways toget this kind of accuracy, but these require expensive specializedequipment that few hospitals have. Besides the potential for these advanced vag diagnostic tool capabilities,enhanced control over testing could make it possible for relativelyuntrained health care workers to administer basic ultrasoundpregnancy tests especially in remote, underserved areas wheretrained sonographers may not be available. The various controltechniques "take the uncertainty out" of the process, Anthony says. Craig Steiner, an anesthesiologist at Chester County Hospital inPennsylvania, says, "I'm excited about the prospects" of theseimproved systems.
"The reproducibility of the scan with consistentpressure and picture quality would help with remote readings oflocally done scans. This could be relevant for teleradiology, whichis an area ripe for expansion." Steiner adds: "The field of ultrasound is still developing.Ultrasound will partially replace CT scans, reduce radiationexposure to patients and make diagnosing easier when away from thehigh-cost hospitals. It can help our world provide care at a morereasonable cost with a new paradigm of care." Source: Massachusetts Institute of Technology.
