This Module describes the Attributes related to dose delivery from an X-Ray source during the acquisition of an X-Ray image.
Table C.8-33. X-Ray Acquisition Dose Module Attributes
The exposure expressed in mAs, for example calculated from Exposure Time and X-Ray Tube Current. |
|||
The exposure expressed in µAs, for example calculated from Exposure Time and X-Ray Tube Current. |
|||
Distance in mm from source to the table, support or bucky side that is closest to the Imaging Subject, as measured along the central ray of the X-Ray beam. Note
|
|||
X-Ray dose, measured in dGy*cm*cm, to which the patient was exposed for the acquisition of this image plus any non-digitally recorded fluoroscopy that may have been performed to prepare for the acquisition of this image. |
|||
The average thickness in mm of the body part examined when compressed, if compression has been applied during exposure. |
|||
Indication of the applied dose, in manufacturer specific units. Note
|
|||
Average entrance dose value measured in dGy at the surface of the patient during the acquisition of this image. |
|||
Average entrance dose value measured in mGy at the surface of the patient during the acquisition of this image. |
|||
Describes what type of dose is represented by the values of Entrance Dose (0040,0302) and Entrance Dose in mGy (0040,8302). Enumerated Values:
Only meaningful if Entrance Dose (0040,0302) or Entrance Dose in mGy (0040,8302) is present. |
|||
Typical dimension of the exposed area at the detector plane. If Rectangular: row dimension followed by column; if Round: diameter. Measured in cm. Note
|
|||
Distance in mm from the source to the surface of the patient closest to the source during the acquisition of this image. |
|||
User-defined comments on any special conditions related to radiation dose encountered during the acquisition of this image. |
|||
The X-Ray output at the patient entrance surface and kVp used to acquire the image, measured in mGy/mAs. |
|||
The thickness of Aluminum in mm required to reduce the X-Ray Output (0040,0312) by a factor of two. |
|||
Average organ dose value measured in dGy during the acquisition of this image. |
