Utilities component). The touch screen will go dark with the exception of one remaining icon. To
"wake" Sprite, tap the screen.
Using the Touch screen Interface
Sprite is equipped with a touch screen for ease of use. Use your finger(s) to tap the screen’s
icons, enter settings and activate buttons.
Required Pre-Scan Procedures
Conditioning maintains the X-ray tube and prepares it for scanning. You may not begin a scan
unless the tube is conditioned; you will be notified of such. To begin conditioning, tap the X-ray
System Maintenance button on the main screen, and then tap the Begin Conditioning button.
Detector calibration prepares the detector for scanning and is essential for accurate image
acquisition. IMTEC recommends you calibrate the detector between once a day and once a
week. To begin detector calibration, tap the X-ray System Maintenance button on the main
screen, and then tap the Begin Calibration button.
Sprite offers automatic X-ray conditioning and detector calibration.
CAUTION: Any liquid around Sprite should be considered a potential electrical shock hazard. You
should not spray, pour or otherwise allow any open fluids in Sprite's vicinity. If you plan on
scanning liquids, they must be nonflammable and in a sealed container.
12

Introduction and Basics
Sample Placement
This topic covers the placement of items in the cabinet. Proper positioning is simple, yet it is
essential to accurate imaging.
Your Sprite system includes canisters and accessories to help ensure the proper placement of
your sample between the X-ray source and the detector. Items that may be used for sample
placement include plastic canisters with specific scanning regions marked, Styrofoam canisters
with shelves or cut-outs for specific samples, open platforms, and a variety of soft foams. These
items are called fixtures. Each of Sprite's fixtures and calibration phantoms is tagged with an
RFID card or sticker.
Canisters and Platforms
Each stage is color coded and has a specific canister and/or platform for its size.
Each canister has Styrofoam inserts to insure the correct placement of the sample within
parameters marked on the canister. These parameters guarantee that your sample will be within
the X-ray scanning field.
Platforms have Styrofoam disks to help adjust height of the item. Other soft foams may also be
used for proper sample placement within the canister or platform.
Calibration Phantoms
Calibration phantoms can be placed directly on the stage.
Sprite comes with color-coded aluminum cylinders, or "calibration phantoms", for each stage . To
test and calibrate the overall imaging system in Sprite, each stage should be regularly (we
recommend monthly) calibrated. This calibration is referred to as a "System Calibration". You
may run a "Validation" to confirm that the system is calibrated correctly.
13

Sprite User's Manual
14
Fixture/Phantom Placement
To begin a full imaging scan, place and secure your sample in the appropriate canister and on the
appropriate stage. To begin a system calibration or validation, place and secure a calibration
phantom on its corresponding stage. (A fixture/phantom is secured when it has been gently
turned until it locks into place. An Audible Announcement informs you the fixture/phantom is
secure.) Shut the cabinet door, tap Begin a New Scan, and choose the proper scanning options.
Notes
•If you cannot open the cabinet door, Sprite's interlock system is probably engaged. The
door will unlock when the X-rays are turned off. For more information, see Safety.
•If you need replacement canisters, stages or foam accessories, please contact technical
support.
•Do not insert flammable or explosive materials inside the Sprite cabinet.
•If you intend to scan liquids, they must be non-flammable and in a sealed container.
