Description
Measure a supplied reference-minus-camera tilt difference.
Clinical movement and practice records distinguish coordinate references, recorded observations, fees and supplied assessment labels. A reference-minus-camera angle differs from an angle wrap, and a right-minus-left coordinate difference is only geometry. Local measures do not diagnose a condition or determine appropriate care.
Measure a supplied reference-minus-camera tilt difference.
When to use this tool
Use Spinal Photo Camera Tilt Residual when you already have recordedCameraTiltDegrees, referenceTiltDegrees and need to measure a supplied reference-minus-camera tilt difference.
How to use the tool and how it works
- Enter recordedCameraTiltDegrees, referenceTiltDegrees. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap. Use the output convention below.
Return referenceTiltDegrees-recordedCameraTiltDegrees.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| recordedCameraTiltDegrees | Recorded Camera Tilt Degrees | Required. Finite number. |
| referenceTiltDegrees | Reference Tilt Degrees | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | referenceTiltDegrees-recordedCameraTiltDegrees; not a wrapped angular difference. | Required. Finite number. |

}Limitations and assumptions
- Angles are not wrapped or inferred from images. No spinal angle, posture, diagnosis, treatment need or appropriate correction is 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
Review the original clinical and measurement records with verified calibration and the complete assessment. Use professional clinical judgment for care questions and actual billing terms for account questions; local coordinate or fee arithmetic does not supply either determination.
