Description
Return a zero-based section-grid address and remaining cells.
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 zero-based section-grid address and remaining cells.
When to use this tool
Use Anatomical Section Grid Cell Address when checking the stated diagram, coordinate, vector or ideal-shape convention.
How to use the tool and how it works
- Enter row, column, columns, rows. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read rowMajorIndex, cellsRemaining. Use the output convention below.
Return a zero-based section-grid address and remaining cells. Require positive whole dimensions and bounded row/column; rowMajorIndex = row*columns+column, cellsRemaining = rows*columns-index-1.1

| columns | Columns | Required. Safe integer; minimum 1. |
| rows | Rows | Required. Safe integer; minimum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| rowMajorIndex | Row Major Index | Required. Safe integer. |
| cellsRemaining | Cells Remaining | Required. Safe integer. |

}Limitations and assumptions
- No actual section image, sampling plan, structure identity or clinical interpretation is validated.
- 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.
