Vanderbilt University Engineer Created Tool That Helps to Find Liver Tumors


    An engineer from Vanderbilt University created a software that helps to find liver tumors, as the liver is predominantly soft and susceptible to shifting both deadly tumors. During surgery, specialist exposed the liver lightly on the surface and taking the shape of the organ, after that the device can match that image with the CT scan on a screen. This approach is better than predicting where the vessels are by feeling for them. Vanderbilt University’s Mr. Michael Miga developed the Pathfinder stylus system for abdominal surgeries. He said, “Deformation happens”. Mr. Michael Miga said, “The way the liver is configured in the body at the time of diagnostic imaging and the way it’s presented for surgery are very different”.

    Further, Mr. Michael said, “If you’re trying to get to a tumor the size of a dime and avoid a blood vessel, you need to avoid errors. The problem is, by the time a surgeon can access the organ for surgery, the CT-derived GPS map could be off by centimeters. That’s dangerous, especially if resecting close to a major vessel”. The method of fixing that error without investing in additional expensive equipment. The device corrects the CT-derived GPS map to better match the organ shape. The specialist was exposed around seven CT images based on the time for 20 patients in the operating room. The specialist associated CT map either to the Pathfinder or to Miga’s new enhanced CT map. Yet, expertise was not commented on which display was being presented, however, the display order was randomized and it could go from enhanced to original, vice versa or held constant. The expertise was able to notice the correct variation among the different evaluations. The modern technology is accessible into image-guided surgery systems.
