DICOM Transfer Time Calculator accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

  • Transfer seconds = study size GB * study count * 8192 / (bandwidth Mbps * efficiency percent / 100 * concurrent transfers).

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • DICOM Modality Preset: CT typical planning - 0.45 GB/study, 2:1
  • Average Study Size: 0.4 GB
  • Study Count: 120
  • Available Bandwidth: 100 Mbps
  • Transfer Efficiency: 80%
  • Concurrent Transfers: 1 streams

Expected outputs

  • Transfer Time: 4d 6h 24m 0s
  • Transfer Time: 102.4 hours
  • Transfer Time: 6,144 minutes
  • Total Data: 3,600 GB
  • Effective Bandwidth: 80 Mbps

Known limitations

  • This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
  • Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

  • 1 GB is treated as 1024 MB and converted to megabits using 8192 Mb per GB.
  • Bandwidth is steady across the transfer window.
  • The estimate is for operational planning and does not validate DICOM conformance or workflow rules.

Unit handling

  • DICOM Modality Preset accepts one of the configured options.
  • Average Study Size accepts values in GB.
  • Study Count accepts numeric values.
  • Available Bandwidth accepts values in Mbps.
  • Transfer Efficiency accepts values in %.
  • Concurrent Transfers accepts values in streams.
  • Transfer Time is displayed in hours.
  • Transfer Time is displayed in minutes.
  • Total Data is displayed in GB.
  • Effective Bandwidth is displayed in Mbps.

Rounding rules

  • Number displays use up to 2 decimal places in the calculator UI.
  • Input precision follows configured step values where provided.
