Description

This file is used to measure the amount of radiation absorbed by a person, known as the "absorbed dose," which reflects the amount of energy that radioactive sources deposit in patients, on a study by study basis, through which they pass.

Kerma in air is` `called 'air kerma'.` `Unit: Milligray (mGy)`
.06	AIR KERMA AREA PRODUCT	0;6	NUMBER	INPUT TRANSFORM: `K:+X'=X!(X>99999)!(X<0)!(X?.E1"."10N.N) X` 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)`
.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)`
100	IRRADIATION INSTANCE UID	II;0	Multiple #70.31	70.31 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)`
