29 Aug WisBusiness: Professor finding new ways to improve medical imaging
A professor at UW-Madison is developing new methods for reducing errors in CT scans, MRIs and other imaging techniques.
Guang-Hong Chen is a medical physics specialist at the Wisconsin Institutes for Medical Research with a number of patents and technologies up for licensing. His work centers on ways to enhance internal medicine by improving how doctors see inside patients.
One widely used tool is known as computerized tomography, or CT imaging. X-ray images are taken of the patient from various angles, and a computer stitches the images together to create cross-sections of the patient’s body. CT scans provide more detailed information than normal X-rays, but the reconstructed images can contain errors known as artifacts.
To avoid these errors, Chen and collaborator Jiang Hsieh created a new way to break down scanned images, separating sections that contain artifacts from others that are compromised. By recombining the sections of the image using a set of image references, they were able to reduce artifacts in the scans they tested.
