Research Interest

Dr. Caldwell has a strong interest in applying methods of digital image analysis and artificial intelligence to clinical problems. For example, Dr. Caldwell is conducting research focused on defining the location and extent of tumours accurately and reproducibly for radiation therapy planning purposes. Currently, the tumour contours are defined manually by physician experts from computed tomographic (CT) images. While it is often possible for the physician to determine if a tumour exists in a general area, it is much more difficult for the expert to determine the boundaries of the tumour. Dr. Caldwell and colleagues have studied this problem for both lung and head and neck cancers, finding that, in many cases, there may be relatively little overlap among the tumour volumes defined by different experts. This is a crucial problem for radiation therapy planning, as the tumour target must be accurately defined for a curative radiation dose to be delivered without giving too high a radiation dose to surrounding normal tissues.
