In simple terms, MVision creates 3D images of the patient's anatomy when the patient is on the examination table waiting to receive radiation treatment.
The significance - doctors can now see and pinpoint the tumor and the exact area they're attempting to treat. In the past, doctors had to rely on 2D views, which were much less detailed and made it more difficult not only to validate the location of the tumor, but also to position the patient for treatment. These 3D images, however, give the physician a more accurate view of the tumor...so that he/she can target the cancer with radiation while sparing the healthy tissue surrounding it.
