FFF.2.1.7.3.1 XA/XRF Acquisition Module Recommendations

The usage of this module is recommended to specify the average values of time, voltage and current applied during the acquisition of the multi-frame image.

It gives general information of the X-Ray radiation during the acquisition of the image. In case of dynamic acquisitions, this module is not sufficient to estimate the radiation per body area and additional per-frame information is needed.

Attribute Name Tag Comment
KVP (0018,0060) Recommended in this scenario.
Radiation Setting (0018,1155) The values “SC” and “GR” give a rough indication of the level of the dose such as “low” or “high”, nevertheless they are used more for quality assurance and/or display purposes, not for estimation of radiation values.
X-Ray Tube Current in mA (0018,9330) Recommended in this scenario.
Exposure Time in ms (0018,9328) Recommended in this scenario.
Exposure in mAs (0018,9332) Recommended in this scenario.
Average Pulse Width (0018,1154) Recommended in this scenario.
Radiation Mode (0018,115A) The value of this attribute is used more for quality assurance and/or display purposes, not for estimation of radiation values.

Note that the three attributes X-Ray Tube Current in mA (0018,9330), Exposure Time in ms (0018,9328) and Exposure in mAs (0018,9332) are mutually conditional to each other but all three may be present. In this scenario it is recommended to include the three attributes.
