4. Press the Hand-switch Prep/Expose button to the Expose position and hold until the
Exposures
Required
reads “0”.
Note:
The exposure hand switch should be held for 18 consecutive exposures to ensure proper tube
warm up. The Exposures Required number counts down as each exposure is made.
5. Wait until the
Soak Time
reads “0”.
6. Click [CLOSE] to finish tube warm up.
You may now continue taking x-rays.
Identification of Radiographs
As in any Radiography procedure, identification of images is important to ensure proper anatomical ref-
erence. Users should take extra care to ensure their image marker/identification placement prior to
exposure is optimal and included in the field of view.
All users are recommended to follow their Institution’s guidelines for image marker implementation.
Note:
Use of electronic/annotated markers as part of post processing is not recommended as a pri-
mary method of image identification because of potential user error in identifying anatomical
regions.
Image Markers
Image markers (e.g. lead markers) are commonly used in identifying radiographs. If image markers are
placed in regions of direct radiation (saturation), there is a possibility they can be processed out of the
image during image processing. Saturated areas beyond the anatomy are no longer part of the final
image. This is most likely to occur to over exposed images.
In cases where image markers become processed out of the image, users may manually adjust the elec-
tronic shutters to include the marker on the final image.
Note:
This may cause Detector Exposure Index (DI) result to change. For instructions on how to adjust
the electronic shutter, please refer to
CAUTION
Exercise care when placing image markers to guarantee their presence in the final
image. Every attempt must be made to assure markers are not located in regions
of direct radiation, but are located in regions where some patient attenuation of
radiation is present without obstructing the anatomical information of interest.
