Digital Volume Tomography (DVT for short) is a three-dimensional imaging technique using X-rays. On a circling path, a high number of projection images is generated, which enables the direct calculation of a 3D volume of the body part to be examined. DVT differs from classical computer tomography (CT for short) in the application of a three-dimensional bundle of rays, allowing for the creation of spatial images. Compared to a conventional CT, the radiation is reduced by at least 50%, hence making DVT the gentlest imaging process there is. The instant availability of the image without prior referral to a radiologist facilitates maximum planning security and an immediate diagnostic solution by the doctor.
The 3D diagnostics for extremities enables a quick diagnosis directly at the treatment site. The high-resolution, three-dimensional quality of the image ensures optimal representation of cartilage and joint damage without being covered by overlying structures - even the finest fractures in the extremities become visible. DVT allows for an imaging of the extremities under load. For this purpose, the patient is standing inside the device during recording. The subsequent image of the ankles or knees displays the anatomy under natural strain and thus reveals problems that otherwise would be undetectable, such as a reduced joint space.
By means of this special X-ray method, cross-sectional images of different body sections with a great level of detail are generated. The examination takes about 20 seconds – afterwards, the images can still be viewed and evaluated during the same appointment. An additional consultation with the radiologist, as well as the additional waiting time in between, is not necessary. The examination itself is simple and comfortable for the patient. Normally, it is carried out while the patient is sitting down, occasionally they will be standing. This means that the method is suitable for wheelchair users. It also proves to be ideal for patients with anxiety and claustrophobia, because there is no narrow tube, just a headrest. The highly realistic image generated from the image data displays a correct anatomical view, making possible to survey changes in a dimensionally accurate way. The exact image of the anatomy can be observed on a monitor from all angles to facilitate its thorough discussion with the patient.
