Basic Principle of DDI:

- Single Stage Process

- Black / White Densities created by TPH

- Film is sensitive to heat only

Single Step Printing

The main cause for the lower sharpness is heat spread and storage in the thermal print head TPH.

Features of Dry Imager: Direct Digital Imaging1. DDI films can be loaded in Day Light, as they are sensitive to heat only

2. DDI is a much newer technology

3. DDI imagers require very less warm up time (5 minutes or less)

4. DDI imagers consume amazingly low power, (to the tune of 700 W Max.)

5. Footprint of Agfa DDI imagers, Drystar Series, is small, saving space

6. DDI imagers produce a square type pixel, as Image on the film

7. Complete range of Drystar to fulfill the need of radiology & imaging

8. Ecologically friendly imager, without use of any harmful chemicals

9. Installed base of over 2,350 imagers for Agfa alone in India

Difference between DDI and Dry Laser:DDI

Single step printingEco-friendly filmsFreehand daylight loadingLess Warm up timeLess Components / ServiceLess power consumptionHigh shelf life (pre & post print)Compact to occupy less spaceDirect DICOM ready

Dry LaserTwo step printingFilms contain developing chemicals

No Imager is pure LASER:

Any Laser Exposure Thermal Development (LETD) Imager, popularly called as Dry Laser Imager, as the

name suggests involves Thermal process within the two staged printing process

:Stage I:Film (light sensitive) which contains embedded chemicals is exposed by a Laser beam. Embedded chemicals act to

actually create the Gray shades:Stage II:

Non reacted part of the emulsion (deemed white part) is removed by a thermal heater. Frequent replacements are required for the filters to keep this fixing process smooth.

Perception of Resolution:DDI

- Perceived resolution is better, even at the same addressability

Dry Laser- Perceived resolution is less, even at the same addressability

Conversion for commonly used interchangeable technical terms

11 Company Confidential

Significance of correct Resolution:DDI

- Modality CR Mammo(Input Resolution of 10 lp/mm)

- Imager(Output Resolution of 10 lp/mm)

- True Size Printing

Dry Laser- Modality CR Mammo

(Input Resolution of 10 lp/mm)- Imager

(Output Resolution of 12.5 lp/mm)- True Size Printing

?

Higher resolution of Imager is not always beneficial

12 Company Confidential

Other technical parameters:Access Time: Better

DDI has much lesser access time contributing to meaningful throughput. One prints many different films on printer; rarely the same film many times.

Gray Scale Resolution: =

Throughput: ~More or less is very close to each other in a practical environment

Number of Input trays: =

Number of supported film sizes: BetterUse of 10 X 12 or 11 X 14 allows maximum utilization of space for images from the modality, typically with the aspect ratios used in medical diagnosis

Maximum Density: Slightly Lesser

Black Border: Not Available
