Ultrasound-Aided Optical Imaging ‘Could Replace Endoscopy’

A novel bio-imaging technique uses a combination of ultrasound and optical processes to noninvasively image body organs through turbid biological tissues such as skin and muscle. This new method, developed at Carnegie Mellon University, Pittsburgh, Pa, has, say its developers, “the potential to eliminate the need for invasive visual exams using endoscopic cameras.”

In other words, according to Maysam Chamanzar and ECE Ph.D. student Matteo Giuseppe Scopelliti, “one day, endoscopes and the like may no longer need to be inserted into the body, such as down the throat or under the skin, to reach the stomach, brain, or any other organs for examination.”

Endoscopic imaging, or using cameras inserted directly inside the body’s organs to investigate symptoms, is an invasive procedure used to examine and diagnose symptoms of deep tissue disease. Endoscopic imagers, or cameras on the end of catheter tubes or wires, are usually implanted through a medical procedure or surgery in order to reach the body’s deep tissues, but Chamanzar’s new technique provides a completely non-surgical and noninvasive alternative.
