| Button | Usage |
|---|---|
| Vertebra (dropdown) | Select a vertebra, then click left vertebral border → spinous process (SP) → right vertebral border. After all three points, rotation% (relative to SP) and the vertebral-center–midline distance are shown. ESC while incomplete = cancel. |
| Midline | Click → yellow vertical reference line. The left–right distance (±) of each SP/point is then shown. |
| Level height + region | Pick a region (clavicle · coracoid · iliac crest · sacral base · femoral head) and click left → right → height difference. |
| Pelvic cavity | Left SI joint inferior (A) → right SI joint inferior (B) → pubic symphysis (C). Pelvic ratio = (perpendicular distance from C to line AB) ÷ (A–B distance). |
| Obturator | Click left medial → horizontal guide → click left lateral (measures distance) → same for the right side. |
| Lesser trochanter–Inferior ramus | Click left Lesser trochanter → horizontal guide → click left Inferior ramus (distance) → same for the right. |
| Cobb's angle | Click two points along the upper endplate of the upper-end vertebra → two points along the lower endplate of the lower-end vertebra. The acute angle between the two endplate lines is shown as the Cobb angle. Multiple measurements supported; click a label then Delete to remove. |
| px/mm (auto) | Reads the per-pixel length from the DICOM PixelSpacing automatically and converts all distances to mm (no separate calibration needed). |
| Sagittal alignment (측면) | 측면(시상면) 전척추 전용. 화면 좌측이 환자 앞(anterior) 기준. 두 모드 제공 — Simple: 4점(C2 치돌기 → C7 대각 2점[상앞·하뒤]의 중점=C7 중심 → S1 후상연)으로 SVA·cSVA 산출(둘 다 C7 중심 기준). Complex: 14점(C2 치돌기·C2 하종판 2점 → C7 네 모서리 → T1 상종판 2점 → L1 상종판 2점 → S1 종판 2점 → 비구 전·후연 2점[중점=대퇴골두 중심])으로 SVA·cSVA·PI−LL·T1S−CL·PT(및 SS·PI·CL·LL) 산출. 추체 중심은 클릭하지 않고 C7 네 모서리의 대각선 교차로 자동 계산. 결과·신호등 해석은 우측 리포트에 표시되며 px/mm 설정 시 거리(mm) 표시. SVA·cSVA의 + 부호 = 앞(anterior) 편위. 측면 작도를 지우려면 측면 라벨(SVA 등)을 클릭해 선택한 뒤 Delete 키를 누른다. |

Basic flow
Double-click a study in the worklist to fill the empty panels. Click an image to activate it (blue border); the left toolbar and shortcuts then apply only to that image.
Measurement tools
· Midline (cc): vertical reference through pubic symphysis
· Pelvic cavity (p) / Obturator (o) / LT-IR (le): left–right symmetry
· Cobb 1 (cb): 4-point endplate measurement
· Cobb 2 (xb): click two measured vertebrae
· Vertebra rotation: pick a level from the dropdown, then click LB·RB·SP
· Level height: clavicle / iliac crest / femoral head left–right heights

Save / close
Save (⌘S) writes the annotation as a sidecar next to the original DICOM. Press ESC twice inside a panel to close just that image.
