2.3 Product DescriptionVistaScan is a scanner using image plates ofvarious sizes. The image plate is an exposuremedium for x-rays whereby the conventional x-ray film is replaced. This storage film is availa-ble in all standard dental formats and storesthe image information similarly to x-ray films.VistaScan changes the image information, byscanning using a laser, into a digital image si-gnal. By this means digital image archivingand processing on a PC as well as fast imageavailablity are achieved. The image informati-on on the storage medium is erased by expos-ure to light and, on careful use of the medium,it may be used several hundreds of times.

7. FUNCTIONAL DESCRIPTION7.1 Function of individual elements

1. Intraoral Image Plate:The image plate serves the same functionas an x-ray film for x-ray exposures.

2. Intraoral Light protection cover:The image plate is placed inside this pro-tective light protection cover for intraoral x-rays. This prevents any mechanical dama-ge when placing the image plate into thepatient's mouth, and avoids any directcontact with the patient.This cover is also protection against roomlighting which would erase the exposure.

3. Foil cassette Sizes:"S2" represents the size of the image platewhich must be used with this particularsize of foil cassette.

4. Foil cassette Sizes - Intraoral:The intraoral image plate is put in to thefoil cassette and then placed in the inletslot of the plate transfer box.This prevents erasure of the exposurewhen working in room lighting.

5. Lever:The intraoral image plate is lifted out of thefoil cassette by operating the small lever.

6. Foil cassette BoxFoil cassettes not being used can bestored in the cassette box.

7. Wall mounting:The VistaScan can be stored by hangingon the wall mounting.

8. Extraoral Image Plate:not for VistaScan Intra 2130-61(as 1 above)

9. Extraoral Foil cassette:not for VistaScan Intra 2130-61(as 4 above)

10. Input slot:When an image plate from the foil cassetteis placed in the input slot of the platetransfer box, a transport mechanism auto-matically pulls the image plate in.

11. Yellow LED:

If the yellow LED lights up, then the VistaS-can is switched on but not yet activated.

If the yellow LED blinks then there is noconnection to the PC, or the data storageis full.

12. On/Off switch:

The VistaScan is switched on (or off) bypressing for 2 seconds.

13. Green LED:

The green LED shows whether the VistaS-can is ready for operation.

14. Optical Scanner:

An optical scanner inside the unit readsthe x-ray image using a laser device andconverts this into a digitalised signal. Theimage plate is then expelled through theoutput slot of the transfer box.

15. Collecting tray:The image plate falls from the output slotonto the tray below the plate transfer box.

16. Plate transfer box:Inside the plate transfer box there is atransport mechanism.

17. Status LED:For each of the slots for foil cassettes thereis a status LED. This LED shows whetherone of the image plates can be insertedfor scanning.

Green LED image plate can be in-serted.

Yellow LED image platecannot be inserted.

7.2 DescriptionVistaScan is a modern, high-resolution scan-ner for image plates. It transforms the x-rayimage information stored on the image plateinto a digital image signal.

The image plate is exposed to x-rays exactlyas a normal x-ray film. This is carried out forpanorama formats* in the appropriate foil cas-sette and for intraoral formats in the (light) lightprotection cover.

After exposure the intraoral image plate isejected from the light protection cover and intothe appropriate sized foil cassette.

The appropriate VistaScan scanning mode isnow selected using the image processing andarchival software, e.g. DBSWIN V 3.1 or high-er.Then the foil cassette containing the panoramaimage plate or, alternatively, the intraoralimage plate is placed in the input slot of theplate transfer box and clicked into correct po-sition.

If the green LED on the plate transfer box dis-plays then the image plate can manually bepushed into the input slot. When using panora-ma formats this is carried out by pushing thethumb through an access slot in the foil cas-sette; for intraoral formats by pushing down onthe lever.

As soon as the image plate has been pushedinto correct position it will be fed into the platetransfer box. Inside the plate transfer boxscanning of the image plate takes place, whe-reby a laser scans the image information andtransmits this to the PC. Scanning progress isdisplayed in a small window on the monitor. Ifa number of intraoral image plates are beingscanned simultaneously, this will be at thesame resolution and sensitivity settings.During the scanning of the image plate, theimage details will be stored in the memory ofthe PC. After scanning the image plate itselffalls into the collecting tray. It can now be re-moved.

Careful handling of this image storage mediummeans that this image plate can be used se-veral hundreds of times. However, any remai-ning image information present must be era-sed by using a light source of a higher densi-ty.Complete erasure is carried out using the DürrReSetter.

After complete erasure the image plate cannow be prepared for use in another exposure.Firstly, check that the image plate is neitherdirty nor damaged. Damaged plates must ne-ver be reused. If the plate is in good conditionit is either put into the special foil cassette foruse in panorama format or, for intraoral format,placed in a new light protection cover andsealed. The image plate can now be used in apanorama film unit, or alternatively placed inthe patient, and a new exposure carried out.

10. SET UP10.1 Operating Room• The VistaScan may only be set up in closed,

dry and well-ventilated rooms.

• Room temperature in the winter may not fallbelow + 10°C and in summer must not ex-ceed + 35°C.

• As condensation can collect if the scanner isbrought into a warm room from a cold envi-ronment, please wait a few minutes after un-packing before connecting to any powersupply so that it can reach room tempera-ture and until it is thoroughly dry.

• Installation in purpose-built rooms, such aswet rooms or heating rooms, is not permit-ted.

• Do not set up the VistaScan in direct sun-light. If possible, room lighting should becontrolled by means of a dimmer.

The VistaScan is sensitive to stray lightduring the scanning phase of imageprocessing. Therefore, the VistaScanshould be set up in a dark room, andfree from direct sunlight (maximum li-ght intensity 1000 Lux). If this value isexceeded the software will detect it(see section 22. Troubleshooting).

• The set up room should not be affected byany interference (e.g. strong magneticfields), this can lead to problems with theVistaScan.

• Peripheral appliances must be kept out ofpatient's reach (1.5 m from patient treatmentarea). (See section 1.6)

10.2 Set-up Alternatives• VistaScan can be used wall-mounted or set

up on a table. In order to avoid errors in thescanning of image detail, the VistaScanmust be protected from knocking orshaking.

• The wall mounting is supplied with neitherscrews nor plugs. Correct installation shouldbe carried out by qualified personnel. Thefixtures must be able to support a weightfour times that of the VistaScan.

The 4 drill holes for mounting in thewall mounting are Ø 7 mm .

16. INTRAORAL X-RAYS16.1 Health Protection

The image plates are toxic.Always put the image plate in a lightprotection cover before placing inthe mouth of a patient.If a patient swallows an image plateor part of a plate then a specialistdoctor should be consulted imme-diately. The image plate must be re-moved. If a patient damages the li-ght protection cover, e.g. throughbiting, the mouth should be rinsedthoroughly with large amounts ofwater.

16.2 Light protection coversThe light protection covers have thefollowing functions:- to protect the patient from any conta-mination from an image plate.- to protect the image plate from anycontamination or dirt.- to protect the image plate from anylight.

• The light protection covers, like the imageplates, are available in different sizes. Al-ways choose the appropriate size.

• Slide the image plate completely into the li-ght protection cover. The passive (printed)side of the image plate must be visiblethrough the transparent side of the light pro-tection cover.

• Remove the white protective strip from theadhesive band and close the opening of thelight protection cover by pressing tightly.

The light protection cover is a dis-posable material and may not bereused.

14

13

23

16.3 X-rays• Before placing the light protection cover into

the patient's mouth it must be cleaned usinga disinfectant wipe (e.g. Dürr FD 350). Alter-natively, spray disinfection agent (e.g. DürrFD 322, FD 333) can be sprayed onto a soft,lint-free cotton gauze.

The image plate is marked with a .This symbol is visible in the x-ray andaids orientation and diagnosis.The image plate must be put into thepatient's mouth so that the symboldoes not affect the usefulness of thefinished radiograph.

• Place the image plate in its light protectioncover in the patient's mouth as normal.

Only use film holders which will notdamage the light protection covercontaing the image plate.

The active side of the image platemust be facing the radiograph tube.

Wear protective gloves when placingthe image plate into the patient'smouth.

• Set exposure time and necessary settingson the x-ray equipment.

• Produce an x-ray as usual.

The image data on the image platemust be scanned into theVistaScan within half an hour.

17

24

16.4 Preparing to Scan Image DataWear protective gloves when removingthe image plate from the patient'smouth.

• The light protection cover should now becleaned using a disinfectant wipe (e.g. DürrFD 350). Alternatively, spray disinfectionagent (e.g. Dürr FD 322, FD 333) can besprayed onto a soft, lint-free cotton gauze.

If more severe dirt, e.g. blood, ispre-sent on the light protection covers and/or the gloves then before disinfectingpreliminary cleaning with a dry cloth isnecessary, e.g. wipe with a clean cel-lulose cloth.

• Place the light protection cover onto thewipe.

• Remove gloves and disinfect hands (e.g.with Dürr HD 410) and clean (e.g. with DürrHD 430 or HD 435).

The powder present on protectivegloves can damage the optical scan-ning equipment of the VistaScan du-ring scanning of the image plate.Therefore, the hands must be entire-ly free of powder before handlingthe image plate.

The storage foil must be absolutelyclean and hygienic before attemp-ting to read the data. Otherwise,data loss with resulting loss of x-rayimaging resolution and even bacte-rial spread to the VistaScan can re-sult.

16.5 Scanning the Image Plate• Turn on VistaScan at On/Off switch. The ope-

ration display is out and the error lamp isyellow.

• Switch on PC and monitor.

• Start image processing software (e.g. DürrDBSWIN V 3.1 or higher).

• Call up the patient's record from the databank.

• Activate VistaScan via software under DürrDBSWIN via the menu "X-ray"). The operati-on lamp displays green.

• Set resolution and format using the software.

21

20

• Tear the light protection cover apart at theadhesive edge (begin at V-notch).

• Have a Foil cassette of the correct size tohand.

•The image plate is removed from the lightprotection cover and put into the film guideuntil it catches. The active side must be tothe rear, and the passive side towards thefront (visible).

The exposure data on the image pla-te will be erased by light. After x-raying never handle the image platewithout either a light protection co-ver or a foil cassette.

26

24

• Set up the software to prepare for scanning.(yellow error lamp of VistaScan no longer ac-tive)

Further details concerning the scan-ning time and file size can be found inthe Appendix.

• Slide the foil cassette with its image plateinto a free slot on the plate transfer box untilit clicks into place.

In order to avoid exposure due to straylight ALL foil cassettes must be clo-sed.

• When the status LED at input slot is green,then the lever can be pressed down untilsuch time as the image plate is automaticallydrawn into the transport box. During scan-ning of the image data the status LED at theinput slot is yellow.

A foil cassette cannot be removed untilall status LEDs are green.

• The scanning progress can be checked onthe monitor.

• Images are automatically transmitted to thesoftware.

• The image plate will fall into the collectingtray. The appropriate LED on the plate trans-fer box will now light green.

• Store the x-ray image using the software.

With the VistaScan it is possible toread up to four intraoral storage filmssimultaneously and where the sameexposure parameters were used.Place all image plates into correctly si-zed foil cassettes. Press the foil cas-settes into position until they click,then use the levers to feed the imageplates into the plate transfer box untilthe box's transport mechanism takesover.

Information concerning recording,storing and processing can be foundin the instruction leaflet of the imageprocessing software.

The scanning time for a panorama image plate with a resolution of 5LP/mm is 24s. This correspondsto a pixel size of 100µm. Pixel sizes under 75µm for panorama views are, due to the particular pro-jection process of OPG X-ray machines, not recommended. For intraoral image formats the pixelsize should lie between 12.5µm and 50µm. If 50µm is used, depending on format the scanningtakes between 14 and 26 seconds. It is important to note that during this time up to 4 image platescan be scanned simultaneously. This is especially useful for standard status images. The default re-solution setting of 20 LP/mm allows structures as small as 25µm to be made visible and therefore,allow more diagnostic possibilities.
