Computer

Colonography (CTC)

The aim of the automated CTC is to decrease the workload for the radiologist not replace them.

In the computer lab, these students test the accuracy of the databases by comparing the results with an already working system.

They are trying to develop software which is  accurate and detects all polyps that may be present in the colon.

The CTC scans the colon and the data is displayed on the computer in a slice-by-slice model of the colon.

The colon is pumped with air so it becomes inflated and you can see the images more clearly. 

 PhD students are developing software which will automatically detect polyps to cut down the amount of data a radiologist would have had to go through to find the polyps. 

VSG are trying to design the databases so that matches the accuracy and sensitivity of the existing one.

They are also trying to reduce the levels of radiation while maintaining the same sensitivity.

If a patient is subjected to high levels of radiation this can damage the cell division which can cause cancer.  However the damage done to the cells depends on the intensity and duration of the exposure.

Since regular screening is the key in prevention of cancer developing, the lower the levels of radiation the less risk it poses for the patients.
