What is it about?
This study aims to reduce or possibly eliminate the use of contrast medium needed for CT imaging to identify the target region for surgical removal in the organ by using non-invasive CT thermometry. Through the experimentation on bovine liver samples, the association between tissue temperature and CT number counts are observed. Cancer patients, particularly those with liver cancer receiving hyperthermia treatment, are to benefit through this research. Support and more comprehensive data on CT images and tumour conditions are required from physicians/radiologist/radiographer/medical physicist for further investigation and perfecting this research.

Why is it important?
The existing procedure used in the evaluation of unresectable liver tumours relies heavily on visual inspection of contrasted CT image. Though widely practiced, this procedure has shown cases of patients being allergic to the medium, and the process tends to cause patient discomfort. Hence, the development of a CT-tissue temperature conversion model as an alternative tool could provide attending physicians the additional information of the target region as well as expedite patient recovery due to its non-invasive nature. The outcome of this research could potentially alter the current hyperthermia treatment procedures for cancer patients.
