INPUT TRANSFORM: K:$L(X)>64!($L(X)<1) X
LAST EDITED: JUN 27, 2013
HELP-PROMPT: Answer must be 1-64 characters in length.
DESCRIPTION:
This is the IRRADIATION INSTANCE UID associated with a CT DOSE instance.
2005.632,2 TARGET REGION 0;3 POINTER TO ANATOMIC TARGET REGION FILE (#2005.6361)
LAST EDITED: JUN 12, 2013
HELP-PROMPT: Select the targeted region.
DESCRIPTION:
This is the anatomical region targeted by the procedure.
2005.632,4 CTDIVOL 0;5 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>99999)!(X<0)!(X?.E1"."10N.N) X
LAST EDITED: MAY 08, 2013
HELP-PROMPT: Type a number between 0 and 99999, 9 decimal digits.
DESCRIPTION: This field is Computed Tomography Dose Index volume. It is approximately the average dose that
would have been delivered to a standard cylindrical plastic phantom for a specific examination. One
phantom is used for head scans and another larger diameter phantom is used for body scans. The
CTDIvol must be adjusted for body size and other factors to estimate the dose to the scanned volume
of each actual patient. However, the CTDIvol is very useful for comparing and adjusting CT imaging
protocols. Unit: mGy (milligray).
2005.632,7 DLP 0;8 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>99999)!(X<0)!(X?.E1"."10N.N) X
LAST EDITED: MAR 01, 2015
HELP-PROMPT: Type a number between 0 and 99999, 9 decimal digits.
DESCRIPTION: This field is the Dose Length Product. The Dose Length Product is the CTDIvol multiplied by the
scan length (slice thickness � number of slices) in centimeters. Unit: mGy-cm
(milligray-centimeters)
2005.632,11 SERIES INSTANCE 0;12 POINTER TO IMAGE SERIES FILE (#2005.63)
LAST EDITED: JUN 12, 2013
HELP-PROMPT: Select the image series.
DESCRIPTION:
This is the image series associated with this CT DOSE instance.

2005.632,12 PHANTOM TYPE 0;13 POINTER TO PHANTOM TYPE FILE (#2005.6362)
LAST EDITED: JUN 26, 2013
HELP-PROMPT: Select the phantom type.
DESCRIPTION: This field indicates which phantom type was used to determine the
irradiation dosage of this irradiation dosage instance. A phantom
is a specially designed object that is scanned or imaged in the field
of medical imaging to evaluate, analyze, and tune the performance of
various imaging devices.
