Using the DVT phantom for training and practice With the aid of the DVT phan- tom and the abovementioned setting techniques, new users, who are training to become dentists or dental technicians, can learn how to set the device for the regions to be examined, generate one or more individ- ual images using the preview function and check whether the setting was correct. In the event of incorrect settings, a better image can immediately be generated. In this manner, there is a direct learning curve. Using the DVT phantom for preparing a patient image Time-consuming and tedious setting (aiming) of the DVT on a patient who is already in the device is likely to be uncom- fortable for the patient. This is where pre-setting the device with the aid of the DVT phan- tom comes in handy. The de- sired region is captured with the phantom and, if needed, is checked with the preview func- tion. Then, the phantom is re- moved and the patient is posi- tioned in the device. Generally, only one device setting for the patient’s body size and small fine-tuning are re- quired before the image is set. HowtoobtainaDVTphantom A DVT phantom can be pro- duced in co-operation with practising dental technicians. The plastic teeth containing barium sulphate are available on the market and a phantom can be made in the manner de- scribed above. An easier option is to send a DVT positioning aid of your device to dtcmfreiburg@aol. com or through www.dtcm- freiburg.de. Master Dental Technician Christian Müller will then mount a prepared DVT phan- tom on your positioning aid. In- dustrially manufactured plastic teeth containing barium sul- phate (SR Vivo Tac/SR Ortho Tac, Ivoclar Vivadent) will be used, which are then incorpo- rated into a mandibular and maxillary model made of trans- parent plastic. We hope that the fascinat- ing field of 3-D diagnostics will establish itself quickly in den- tistry and remain an imaging procedure that significantly ex- pands upon the hitherto range of dental X-ray diagnostics in the long term.
