Description
Split a supplied research lesion identifier under an explicit delimiter convention without characterizing lesions.
Research lesion records distinguish measured dimensions, geometric size models, censoring conventions, assessment denominators, and follow-up timing. An axis product, percent change, or coverage measure describes only its stated inputs and model. Such arithmetic does not automatically implement a clinical response criterion or validate a study.
Split a supplied research lesion identifier under an explicit delimiter convention without characterizing lesions.
When to use this tool
Use Research Lesion ID Split Token when you need this research measurement, assessment-base, source, or event-time calculation.
How to use the tool and how it works
- Enter token, delimiter, expectedParts. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read parts, partCountMatches. Inspect partCountMatches before interpreting the associated values.
For nonempty delimiter and expectedParts from one through 256 split token literally. Return parts and partCountMatches on exact expected length.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| token | Token | Required. Text; maximum UTF-16 length 8192. |
| delimiter | Delimiter | Required. Text; maximum UTF-16 length 8192. |
| expectedParts | Expected Parts | Required. Safe integer; minimum 1; maximum 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| parts | Parts | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| partCountMatches | Part Count Matches | Required. Boolean. |

}Limitations and assumptions
- Empty pieces and repeated delimiters are retained. No lesion identity, anatomical location, source namespace, or clinical coding validity is established by the part count.
- 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 the intended study protocol and a complete measurement or analysis model for a broader conclusion. Verify lesion definitions, censoring, measurement correspondence, time anchors, and missing-assessment policy.
