Squishy viscera, such as the liver, can change their shape significantly from the time a CT scan is taken that spots a tumor to when its excised during surgery. Various tags have been developed that can be tacked onto tissue in order to use as a point to calibrate against, but this approach still doesnt quite achieve the desired precision. Researchers at Vanderbilt University have now developed an algorithmic approach that correlates CT scan data with how the soft tissue is manipulated during surgery, guiding the surgeon to the correct location of the target tumor. The software models the movement of the organ as it would be squeezed and moved by the surgical team during a procedure, adjusting the location of the tumor and displaying its new location on a computer screen.
