The software’s accuracy of the measured and calculated parameters, and the segmentations
was proved during the clinical investigation to be:
| Measurements | Accuracy [%] |
|---|---|
| Intervertebral angles, ° | 90.00% |
| L1S1 lordotic angle, ° | 86.00% |
| Spondylolisthesis slippage, % | 90.00% |
| Vertebral height, mm | 78.00% |
| Disk height, mm | 82.00% |
| Herniation size, mm | 78.00% |
| Dural sac area, mm² | 81.00% |
| Aorta diameter, mm | 93.00% |
| Bulging size, mm | 80.00% |
| Canal diameter, mm | 80.00% |
| Segmentations | Accuracy [%] |
|---|---|
| Vertebra (on axial slice) | 82.00% |
| Disk – not herniated (on axial slice) | 87.00% |
| Herniated part of the disk, without sequestration (on axial slice) | 85.00% |
| Dural sac (on axial slice) | 84.00% |
| Ligamentum flavum (on axial slice) | 80.00% |
| Nerve roots (on axial slice) | 78.00% |
| Aorta or iliac artery (on axial slice) | 88.00% |
| Vertebra (on sagittal slice, only around mid-sagittal, 35 mm) | 81.00% |
| Disk – not herniated (on sagittal slice, only around mid-sagittal, 35 mm) | 91.00% |
| Appropriately chosen planes* | 70.00% |
| Sacrum (on sagittal slice) | 87.00% |
