"I think the reason for that is that we can do so much more with 3D CT than one can do with traditional colonoscopy. We can straighten out the colon" which gives the specialists novel perspectives, he says. Additionally, using virtual colonoscopy eliminates the need for sedation and thus may make the procedure more acceptable to patients.
Penrod and Johnson agree that patients may drive acceptance of "virtual reality" imaging because the noninvasive nature is appealing to many patients.
Currently, Johnson says the inner ear program is being used mainly as an educational tool. He says, however, that he is planning a large-scale study to compare the accuracy of the program with more traditional techniques.
