LAST EDITED: MAY 07, 2015
HELP-PROMPT: Type a number between 0 and 999999, 9 decimal digits.
DESCRIPTION: Kinetic energy released in matter (Kerma), is defined as the sum of the initial energies of all the
charged particles liberated by uncharged ionizing radiation in a material of given mass per unit
mass. Kerma in air is called 'air kerma'.
Unit: Milligray (mGy)

LAST EDITED: MAY 07, 2015
HELP-PROMPT: Type a number between 0 and 99999, 9 decimal digits.
DESCRIPTION: Air Kerma Area Product is defined as the air kerma at a particular location in an x-ray beam
multiplied by the cross-sectional area of the beam at that location. It is an approximate
indication of the total amount of energy delivered by the x-ray beam.
Unit: Gray centimeters squared (Gy-cm2)
70.3,.07 TOTAL FLUOROSCOPY TIME 0;7 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>99999)!(X<0)!(X?.E1"."3N.N) X
LAST EDITED: FEB 05, 2013
HELP-PROMPT: Enter the total amount of time the patient was exposed to fluoroscopy sourced radiation. This value
must be a number from 0 to 99999, 2 decimal digits.
DESCRIPTION: The ability of fluoroscopy to display motion is provided by a continuous series of images produced
per second. High radiation exposures to patients can result from multiple series of images.
Therefore, total fluoroscopic time is one of the metrics that determines the exposure to the
patient from fluoroscopy.
Unit: seconds (time)
70.3,100 IRRADIATION INSTANCE UID II;0 Multiple #70.31 (Add New Entry without Asking)
DESCRIPTION: An irradiation event is the occurrence of radiation being applied to a patient in a single
continuous time-frame between the start (release) and the stop (cease) of the irradiation.
This sub-file is a record of up to five of the highest irradiation instances for this study.
INDEXED BY: DLP (DLP)
70.31,.01 IRRADIATION INSTANCE UID 0;1 FREE TEXT (Required) (Multiply asked)
INPUT TRANSFORM: K:$L(X)>64!($L(X)<3)!'(X?1.N1".".PN) X
LAST EDITED: MAY 30, 2013
HELP-PROMPT: The Irradiation Instance UID must be 3-64 characters in length.
DESCRIPTION: An irradiation event is the occurrence of radiation being applied to a patient in a single
continuous time-frame between the start (release) and the stop (cease) of the irradiation.
TECHNICAL DESCR: The Irradiation Instance UID is defined as a character string containing a UID that is used to
uniquely identify a wide variety of items. The UID is a series of numeric components separated by
the period "." character. If a Value Field containing one or more UIDs is an odd number of bytes
in length, the Value Field shall be padded with a single trailing NULL (00H) character to ensure
that the Value Field is an even number of bytes in length.
DICOM Value Representation: UI (Unique Identifier) Data format: "0"-"9", "." (A series of numeric
components separated by the period "." character)

70.31,2 ANATOMICAL TARGET REGION 0;2 POINTER TO ANATOMIC TARGET REGION FILE (#2005.6361)
LAST EDITED: APR 11, 2013
HELP-PROMPT: Enter the part of the body scanned.
DESCRIPTION: This is the part of the body scanned through the emitting of a series of x-ray beams.
For example, you might need a CT scan of the brain, liver, kidneys, or lungs. The target areas of
CT scans are usually sinuses, the head, chest, abdomen, and pelvic regions.
70.31,3 PHANTOM TYPE 0;3 POINTER TO PHANTOM TYPE FILE (#2005.6362)
LAST EDITED: APR 11, 2013
HELP-PROMPT: Enter the appropriate phantom used in this instance.
DESCRIPTION: A model of the human body or any of its parts used for predicting irradiation dosage within the
body.
70.31,4 CTDIvol 0;4 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>99999)!(X<0)!(X?.E1"."10N.N) X
LAST EDITED: MAR 10, 2015
HELP-PROMPT: Type a number between 0 and 99999, 9 decimal digits.
DESCRIPTION: The Computed Tomography Dose Index volume (CTDIvol) 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 a actual patient. However, the CTDIvol is very useful for comparing and adjusting CT
imaging protocols.
Unit: mGy (milligray)
70.31,5 DLP 0;5 NUMBER
INPUT TRANSFORM: K:+X'=X!(X>99999)!(X<0)!(X?.E1"."10N.N) X
LAST EDITED: MAR 10, 2015
HELP-PROMPT: Type a number between 0 and 99999, 9 decimal digits.
DESCRIPTION: The Dose Length Product (DLP) is the CTDIvol multiplied by the scan length (slice thickness *
number of slices) in centimeters.
Unit: mGy-cm (milligray-centimeters)

ARAD (#1148) RECORD REGULAR IR SORTING ONLY
Short Descr: This is a compound cross-reference on fields: .01, .02 & .03.
Description: This is a compound cross-reference that ties fields .01, .02 & .03 together.
The construction of this cross reference is as follows: ^RAD("ARAD",EXAM DATE/TIME,PATIENT,CASE NUMBER)=""
EXAM DATE/TIME is field number .02; PATIENT is field number .01 & CASE NUMBER is field number .03.
^RAD("ARAD",.02,.01,.03)=""
This lookup cross reference allows faster lookups for patients exposed to radiation at the time the examination
was performed because it ties in nicely with file-wide "AR" cross reference on EXAM DATE (70.02) and the "B"
cross reference on CASE NUMBER (70.03).
