Description
Return a supplied vertebral-order index gap.
Anatomical diagrams and idealized models require explicit coordinate origins, axes, dimensions and indexing conventions. Translations, vector projections and simple shape formulas describe supplied geometry rather than identifying actual anatomy or determining a medical finding. A scaled drawing or ideal branching tree needs separate anatomical verification.
Return a supplied vertebral-order index gap.
When to use this tool
Use Vertebral Level Supplied Order Gap when checking the stated diagram, coordinate, vector or ideal-shape convention.
How to use the tool and how it works
- Enter firstIndex, secondIndex, indexIncreasesInferiorly. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedIndexGap, inferiorSteps. Use the output convention below.
Return a supplied vertebral-order index gap. Require nonnegative whole indexes; signedGap = second-first, inferiorSteps equals signed gap or its negation according to indexIncreasesInferiorly.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstIndex | First Index | Required. Safe integer; minimum 0. |
| secondIndex | Second Index | Required. Safe integer; minimum 0. |
| indexIncreasesInferiorly | Index Increases Inferiorly | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedIndexGap | Signed Index Gap | Required. Safe integer. |
| inferiorSteps | Inferior Steps | Required. Safe integer. |

}Limitations and assumptions
- The ordering is supplied and no vertebra is identified; actual anatomy, imaging findings and clinical interpretation are not established.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified anatomical measurements and an appropriate complete spatial model; consult qualified health professionals for actual medical interpretation.
