DLP as input in NCICT

I was wondering if there was a way to use DLP as an input rather than a calculated field? My scanner does not provide scan start and end position. Only CTDiVol, kV, and DLP. Our scan length is usually fixed, but easily calculated by dividing DLP by CTDiVol. I was wondering if there was a way to utilize the NCICT with the data our scanner provides. I have attached a screenshot of the dosimetry console data.
NCI Dose Team response
We understand that your CT scanner dose summaries do not directly provide the scan start and end positions in cm required by NCICT, which is common. In this case, a practical approach is to select the closest predefined NCICT protocol, enter the reported CTDIvol, estimate the scan length as DLP/CTDIvol, and then customize the scan end position by adding the estimated scan length to the predefined scan start position. This provides a reasonable protocol-based approximation.
