4.1. SITE SELECTION
SECTION 4: INSTALLATION
The EPIX SCANNER can be located almost anywhere the operating conditions are met. The site you pick should have:
œ Subdued lighting conditions. You should
have the ability to turn down/off the lights and block sunlight with blinds. The area to be used for mounting imaging plates should not exceed 20 lux as measured on a light meter. This will give you about one minute to mount all of your imaging plates without encountering excess signal fading. If you cannot measure the light in the room where you wish to mount the imaging plates, you should turn off the room lights, close all blinds and leave the door open just enough so that you can see to mount the imaging plates. This should make the light level about 10-20 lux. If you need more than one minute, refer to appendix B.
œ A stable, flat countertop large enough to
hold the scanner plus provide a working area. We suggest a minimum of 18 x 36 in. (46 x 92 cm). The computer does not need to be on the countertop, but must
be within the length of the USB cable (6ft or 2m provided). If a longer cable is needed, it should not be longer than maximum 12 ft. (4 m). The countertop must be able to hold the weight of the unit or a minimum of 60 lbs (27 kg).
œ Access to a standard grounded electric
outlet.
œ Enough room to allow the operator to
mount imaging plates and use the computer effectively.
If you choose to put the system in your darkroom, please prepare the site by:
œ Removing all old film processing
equipment and plumbing.
œ Remove the safelight filter and adjust the
intensity of the light by lowering the bulb wattage until the intensity of the light around the scanner is 20 lux or less.
œ We recommend that you keep the light
off and the door open when mounting imaging plates to the carousel. The light from the open door will allow you to see enough to mount the imaging plates but will not adversely affect the image.

SECTION 5: SYSTEM OPERATING INSTRUCTIONS
5.1. PREPARING YOUR CURRENT X-RAY EQUIPMENT
The EPIX Digital Imaging System produces x-ray images of high quality and low noise. More details on how this technology works can be found in appendix A. Almost any x­ray unit can be used with the EPIX system. There is no need to purchase a new one. The imaging plates can produce an excellent
5.2. ERASE THE IMAGING PLATE
Imaging plates should be erased just prior to use. Scanning an imaging plate does not erase all the image information. To completely erase the imaging plate, expose the front surface (blue or white in color) to direct, intense light for at least 2 minutes.*
An effective way to erase the imaging plate is to use a light box. Simply lay down the imaging plate active side up (blue or white face) facing the light box shining down. Expose the plates to light for about 2 minutes. To avoid scratching the imaging plates, refrain from lying the imaging plate active face down on a light box.
image over a wide range of exposures. With the EPIX system, it is possible to get high­quality images at the same exposure time you use for x-ray film. This is a great benefit to you because it means that it will be more difficult to over- or under-expose an image.
Alternatively, place the imaging plates within 8 inches of a lamp equipped with a lit 100-watt bulb for two minutes, minimum. The imaging plates are now completely erased and are ready for reuse. Avoid using sunlight since it contains UV light that can deeply stimulate the phosphor and leave artifacts in the image. Longer, non-UV light erasing may be required to rid the image plate of these artifacts.
*Note: Erasing time will vary depending on the quality and intensity of the erasing light. For more detailed information, see appendix B.

How Storage Phosphor Imaging Plates Work
Each EPIX SCANNER Imaging Plate is made up of a very thin layer of tiny storage phosphor crystals that are bonded together and coated on a flexible sheet of plastic. These storage phosphor crystals have the ability to capture
the energy of x-rays and store the pattern as a latent image (see diagram).
In essence, they act as an “energy trap,” storing x-ray energy. The amount of energy stored is directly proportional to the amount of x-ray energy the crystal was exposed to.
The EPIX SCANNER further excites the phosphor crystals to an unstable state by exposing them to a red laser. The phosphor crystals then release a blue light and return to their stable ground state. The EPIX SCANNER reads this blue light and, with the imaging software, produces an image.
This process does not completely erase the imaging plate. Some crystals remain as “energy traps.” This information can be erased by exposing the imaging plate to light. A few seconds of low levels of light will usually not effect the image quality. Once erased, the imaging plate can be re-exposed and the process can begin again. With proper handling, EPIX SCANNER Imaging Plates can be continually reused.

Appendix B: Lighting Conditions for Handling or Erasing Imaging Plates
Without light, storage phosphor imaging would not work. The red light from the laser scanner excites the exposed imaging plates, causing them to emit blue light. After your computer interprets the blue light and changes it into a digital image, light is used to erase the residual information from the imaging plate.
Between x-ray exposure and scanning, however, one must be careful handling the imaging plates. An imaging plate should never be removed from its protective sleeve or cassette and exposed to a strong source of light. This act would erase the latent image from the plate. Therefore, you must load imaging plates onto the carousel under controlled light ing conditions. The recommendations below have been developed to ensure that you obtain excellent image quality.
Recommendations on Lighting Conditions for Loading Carousels
œ Fluorescent Lights
If loading can be accomplished in less than 60 seconds, the fluorescent lighting in the
area should not exceed 20 lux. If loading will take longer than 60 seconds, the room conditions need to be darker. At 10 lux, the operator has about 5 minutes to accomplish loading.
œ Incandescent Lighting
Incandescent lighting is about half as efficient as fluorescent lighting at fading imaging plates. Here, again, we recommend lighting conditions of around 20 lux. Under incandescent lighting, however, you have about 2 minutes to complete the loading process. If it takes longer than 2 minutes, decrease the amount of light to 10 lux.
œ Sunlight
Sunlight is the most efficient light for fading imaging plates. Additionally, it is very difficult to judge the intensity of sunlight. Loading carousels under sunlight is not recommended.
If you cannot darken your mounting area to 20 lux or less, contact your local Logos Imaging representative for suggested mounting times.

Recommendations on Lighting Conditions for Erasing Imaging Plates
In order to completely erase imaging plates,
99.5% of the image information must be removed. Scanning only removes part of the information. To completely erase imaging plates, follow the guidelines given below. It is important that you measure the light intensity with a light meter at the point where the imaging plate will be positioned. The intensity of light changes dramatically as you move away from the source. Erasing the imaging plates for periods of time longer than suggested does not harm them. A good place to store your imaging plates is under the erasing light source.
œ Fluorescent Lights
A light box typically gives off between 1000 and 5000 lux. Measure your light box and use the lowest value to determine the erasing time. At 1000 lux, an imaging plate will be erased in 1 minute. At 2000 lux or more, 30 seconds is sufficient.
œ Incandescent Lighting
At 1000 lux, an imaging plate will be erased in about 2 minutes. At 2000 lux or more, erase for 1 minute.
œ Sunlight
Full sunlight on a bright day can be as strong as 70,000 lux. At this intensity, it takes less than 10 seconds to erase imaging plates. However, sunlight is too variable, and we do not recommend using it.
If you are unable to directly measure the light output from your erasing light source, or do not have an erasing light source greater than 1000 lux, use the practical test, below, to determine your erasing time.
Practical Test
1. Completely erase an imaging plate by
subjecting it to direct, intense light for about 20 minutes.
2. Scan the imaging plate. No image should
appear on the monitor. If an ima ge does appear, repeat step 1 with a more intense light source.
3. Place the imaging plate in a sleeve or
cassette.
4. Expose the imaging plate using normal
exposure conditions. If possible, place an object, in the path of the x-ray beam.
5. Turn on your erasing light source. We
recommend a light box or a minimum l00­watt incandescent light bulb (see Section
5.2).
6. Remove the imaging plate from its sleeve
or cassette and place it with the blue side toward the light for 2 minutes.
7. Scan the imaging plate. If an image
appears, the plate was not completely erased. Repeat step 6, adding a minute to the exposure time. Continue to repeat until no image appears on the monitor. Record the erasing time that resulted in no image. This is the time required to erase an unscanned imaging plate.
8. Repeat steps 1-4. This time, under low
light conditions, remove the imaging plate from the sleeve or cassette and mount it on the carousel. Scan the imaging plate.
9. Remove the scanned imaging plate and
place it, in the dark, into a light-protected area (such as a light-tight drawer.
10. Now repeat steps 6 and 7, exposing one
plate (blue side toward light) to the erasing light for 2 minutes, the next plate for 3 minutes, etc., until you find the point where no image appears on the monitor. This is the time required to erase a scanned imaging plate.
The time required to erase an imaging plate will vary depending on the quality and intensity of the erasing light source. It should be fairly easy to find a light source that will erase imaging plates in 2-3 minutes.

Appendix C: Optional Printer
Because the EPIX SCANNER system can be interfaced with different applications software, and printer technology is constantly evolving, we can only suggest a list of suitable technical requirements for printers.
œ To interface with the PC, the printer must
have a digital input and not a video (analog) input.
Inkjet printers
Black and white or color hard copy. Printers should have a minimum of 600 dpi resolution and pseudo-randomic dithering. Using the standard Windows® drivers allows the use of the same printer for all other Windows applications (word processing, etc.).
The Epson Stylus Photo product line is suitable for printing moderate to good quality images. We recommend using the photographic quality glossy paper and printing on the highest resolution setting available.
Dye Sublimation printers
Advised whenever the EPIX SCANNER System is used when high printing quality is required.
Application software
Please refer to the instructions in the application software for special information about printers.
