1 mm

Question: Which structure could be shown with a high diagnostic value by a resolution of 1 LP/mm.Physical basis: The sampling theorem defines:- To show accurately a certain structure you have to sample with half of the dimension of the structure.Result: With the resolution of 1Lp/mm you could detect a structure size of 1mm with a high diagnostic value.

Test conditions• The time to the first image is based for all systems on

the readout time only.• For the further images the plates are pulled out of the

barrier envelope (for VistaScan directly into the cassette; for Digora on the table in the paper cover).

• The DenOptics has to be loaded completely on the drum. To add an image plate the carousel has to be taken out.

• With Digora you have a handling time of approx. 4sec. to load each plate and start the scanner. You have to stay at the scanner the whole time.

• With VistaScan Perio you can pre-load upto 4 cassettes (8 plates) and leave the system to use the time for other things. At any time you can load an additional cassette.

Time savings- Image `developed´ within seconds- Direct image processing (e.g. Measurements)- Images available at any time, patient related archiving. - Fast and all inclusive PC based patient communications



Advantages of image plates

23.04.23

23.04.23


• Wide latitude of exposure – avoids over and under exposures

• Dynamics and contrast on the level with conventional film

• All formats available (S0, S1, S2, S3, S4)

• Easy placement within the patients mouth

• Reusable
