Row 1 |
Dose applied by this irradiation event, relative to defined reference point. |

|
|
Modifier shall indicate "Estimated" |
|
|
|

Row 9 |
Pulse width as measured/recorded by the system, either as a single total value, or as multiple values. If |

|
|
multiple values are provided, their number shall match the value in Row 7 "Number of Pulses". |
||||||
Row 11 |
KVP value as measured/recorded by system, either as a single mean value, or as multiple values. If multiple |

|

values are provided, their number shall match the value in Row 7 "Number of Pulses". |
||||||
Row 12 |
Tube current as measured/recorded by system, either as a single mean value, or as multiple values. If |

multiple values are provided, their number shall match the value in Row 7 "Number of Pulses". |
||||||
Row 14 |
Exposure time as measured/recorded by the system. |
|
|

Row 15 |
Exposure as measured/recorded by system, either as a single total value, or as multiple values. If multiple |
|||||||
|
|
values are provided, their number shall match the value in Row 7 "Number of Pulses". The Exposure will be |
||||||
|
|

||||||
|
|
and exposure time. |
|
|
|
|

Row 18 |
If one or more Filter(s) were applied during this irradiation event |
|
||||||
Row 23 |
Collimated area at the receptor plane. |
|
|
|
|
|||
Row 27 |
The device that produced the irradiation in this Irradiation Event. I.e., the X-Ray source. |
|||||||
This is not required to be present if the information is the same as that already recorded in TID 1004 “Device Observer Identifying Attributes” encoded via the inclusion of TID 1002 “Observer Context” in TID 10001 “Projection X-Ray Radiation Dose” Row 5, which in turn may be absent if identical to the content in the Enhanced General Equipment Module.

Rows 5, 6 |
Total Number of CT irradiation events. |
|
A CT irradiation event is one continuous irradiation procedure and is defined through consistent acquisition |
|
parameters. |
|
In the case of dose modulation the calculations are based on the effective parameters (e.g., the effective mA |
|
recorded in the Mean X-Ray Tube Current), and these acquisition parameters are consistent. |
Rows 5, 6 |
The Dose Length Product (DLP) is calculated for every irradiation event. The Dose Length Product Total is the |
|
sum of the DLP values. The calculation is based on the CTDIvol result of each irradiation event. |
Rows 5, 6 |
Effective dose (E, in units of mSv) evaluated as a total over the scope is defined in Row 6 of Template TID |
|
10011 “CT Radiation Dose”. |
|
Effective dose is defined by the reference in Rows 5 or 6 of this Template. |
|
It may be calculated from a product of DLP and an 'Effective Dose Conversion Factor' (E/DLP). Or it may be |
|
calculatedfromaproductoftheMeanCTDIfreeairandtheratioE/CTDIfreeair.TheratiosE/DLPorE/CTDIfreeair |
|
may be evaluated either from computer simulations applying Monte Carlo (MC) sampling techniques or from |

dosimetric measurements in an anthropomorphic phantom, e.g., the Alderson-Rando phantom.. The specific |

method used is identified in Rows 7 through 11. |
