Research tool — not a regulated medical device. Their results are not a diagnosis and can be wrong. Every result must be reviewed by a qualified clinician, who remains responsible for the clinical decision.

A pre-computed example: right and left lung on a real chest CT, in an interactive 3-plane + 3D viewer. Drag to scroll slices; switch to 3D for the surfaces.
For scale — total lung capacity (TLC) is the full lungs at a maximum breath-hold, not what a routine chest CT captures. Population averages; an individual varies with height more than with age.
| Group | Typical TLC |
|---|---|
| Adult man | ≈ 6.0 L |
| Adult woman | ≈ 4.2 L |
| Child, ~5 years | ≈ 1.3 L |
| Child, ~8 years | ≈ 2.1 L |
| Child, ~11 years | ≈ 3.0 L |
| Adolescent, ~14 years | ≈ 3.9 L |
