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.
.01patient(+)0;1POINTER2BThis field identifies the patient absorbing radiation associated with this exam.
.02exam date/time(+)0;2DATE-TIMEThis field identifies the exam date/time of the exam.
.03case number(+)0;3NUMERICThis field tracks the case number of the exam.
.04dose collected within the va?0;4BOOLEAN1:Yes
This field tracks whether the exam introducing the radiation was performed under the direction of the Department of Veterans Affairs (VA).
.05air kerma0;5NUMERICKinetic 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: Gy (Gray)
.06air kerma area product0;6NUMERICAir 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: Gy-cm2
.07total fluoroscopy time0;7NUMERICThe 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)
100irradiation instance uidII;0MULTIPLE70.31An 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.
