.01 | id(+) | 0;1 | FREE TEXT | B | This is a unique ID assigned to each CT DOSE instance. | |
1 | irradiation instance uid | 0;2 | FREE TEXT | This is the IRRADIATION INSTANCE UID associated with a CT DOSE instance. | ||
2 | target region | 0;3 | POINTER | 2005.6361 | This is the anatomical region targeted by the procedure. | |
4 | ctdivol | 0;5 | NUMERIC | 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). | ||
7 | dlp | 0;8 | NUMERIC | 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) | ||
11 | series instance | 0;12 | POINTER | 2005.63 | C | This is the image series associated with this CT DOSE instance. |
12 | phantom type | 0;13 | POINTER | 2005.6362 | 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. |
