Table C.8-27. X-Ray Acquisition Module Attributes
X-Ray Tube Current in mA. Required if Exposure (0018,1152) is not present. May be present otherwise. |
|||
Duration of X-Ray exposure in msec. See Section C.8.7.2.1.1. Required if Exposure (0018,1152) is not present. May be present otherwise. |
|||
The exposure expressed in mAs, for example calculated from Exposure Time and X-Ray Tube Current. Required if either Exposure Time (0018,1150) or X-Ray Tube Current (0018,1151) are not present. May be present otherwise. |
|||
The exposure expressed in µAs, for example calculated from Exposure Time and X-Ray Tube Current. |
|||
Type of filter(s) inserted into the X-Ray beam (e.g., wedges). |
|||
Shape of the Image Intensifier Field of View. See Section C.8.7.2.1.2. |
|||
Dimensions of the Image Intensifier Field of View in mm. If Rectangle, row dimension followed by column; if Round, diameter. |
|||
Physical distance measured at the front plane of the Image Receptor housing between the center of each pixel specified by a numeric pair - row spacing value(delimiter) column spacing value in mm. See Section 10.7.1.3 for further explanation of the value order. The value of this Attribute shall never be adjusted to account for correction for the effect of geometric magnification or calibration against an object of known size; Pixel Spacing (0028,0030) is specified for that purpose. |
|||
Include Table 10-10 “Basic Pixel Spacing Calibration Macro Attributes” |
|||
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. |
Exposure time is the cumulative time the patient received X-Ray exposure during this image (Multi-frame image acquisition). Calculation is pulse width * number of frames.
The Field of View Attribute describes the shape and dimensions of the Image Receptor Field of View, applicable to both Image Intensifier and Digital Detector. This could be further restricted by the Collimator. See Section C.8.7.3.
