|||
|
See C.8.13.2.1.1 for further explanation. |
|||
|
The date and time that the acquisition of data that resulted in this image started. |
|||
|
The time in seconds needed for the compete acquisition. See C.7.6.16.2.2.1 for further explanation. |
|||
|
Include Table C.8-71b “Digital X-Ray Detector Macro Attributes” |
|||
|
Average of the peak kilo voltage outputs of the X-Ray generator used for all frames. |
|||
|
Average of the nominal X-Ray tube currents in milliamperes for all frames. Required if Exposure in mAs (0018,9332) is not present. May be present otherwise. |
|||
|
Total (cumulative) duration of X-Ray exposure for all acquired frames in milliseconds. Required if Exposure in mAs (0018,9332) is not present. May be present otherwise. |
|||
|
The total (cumulative) exposure for all acquired frames expressed in mAs, for example calculated from Exposure Time and X-Ray Tube Current. Required if either Exposure Time in ms (0018,9328) or X-Ray Tube Current in mA (0018,9330) is not present. May be present otherwise. |
|||
|
The average thickness in mm of the body part examined when compressed, if compression has been applied during exposure. |
|||
|
The compression force applied to the body part during exposure, measured in Newtons. |
|||
|
Description of the compression paddle, if compression was applied to the body part during exposure. |
|||
|
Text description of the mechanism of exposure control. May describe the number and type of exposure sensors or position of the sensitive area of the imaging detector. |
|||
|
Patient direction of the rows and columns of the most representative frame. Required if View Code Sequence (0054,0220) has an Item value other than one representing a specimen image. May be present otherwise. |
|||
|
Number of bits allocated for each pixel sample. Each sample shall have the same number of bits allocated. |
|||
|
Number of bits stored for each pixel sample. Each sample shall have the same number of bits stored. |
|||
|
Most significant bit for pixel sample data. Each sample shall have the same high bit. Shall have an Enumerated Value of one less than the value of Bits Stored (0028,0101). |
|||
|
Data representation of the pixel samples. Each sample shall have the same pixel representation. |
|||
|
Indicates whether or not this image is a quality control of phantom image. |
|||
|
Indicates whether or not the image contains sufficient burned in annotation to identify the patient and date the image was acquired. |
|||
|
Specifies whether an Image has undergone lossy compression (at a point in its lifetime). Enumerated Values: Once this value has been set to 01 it shall not be reset. See Section C.7.6.1.1.5. |
|||
|
Describes the approximate lossy compression ratio(s) that have been applied to this image. |
|||
|
A label for the lossy compression method(s) that have been applied to this image. |
|||
|
Organ dose value measured in dGy representing the collective total for all acquired frames. |
|||
|
Entrance dose value measured in mGy at the surface of the patient representing the collective total for all acquired frames. |
|||
|
Describes the activity of the Detector during acquisition. See C.8.31.1.1 for Defined Terms. |
|||
|
This icon image is representative of the Image. Only a single Item is permitted in this Sequence. |
|||
|
See C.7.6.1.1.6 for further explanation. |
|||
|
Specifies a transformation for the Presentation LUT such that the output of all grayscale transformations, if any, is defined to be in P-Values. |
|||
Positioner Motion (0018,1500) and Type of Detector Motion (0054,0202) shall have the Defined Terms specified in Table C.8.31.1.1-1.
Complex motion is defined as that which is not simply described by linear translation or rotation around an axis.
