Computed tomography (CT)
Judge the volume, not the best slice.
The existing benchmark summarises reconstruction across eligible interior slices. Local masked measurements reduce the optimism caused by unchanged image background.
All-slice reconstruction benchmark
Read medians, quartiles and the worst observed value together. The local SSIM threshold is descriptive, not a clinical or official pass criterion.
Load the recorded benchmark to view body-envelope and HU-band summaries.
Body-envelope measurements
The body envelope reduces external-air influence. It is an image-processing mask, not a validated lung, organ or tumour segmentation.
Errors by HU intensity band
Lung-range, soft-tissue-range and high-density pixels are intensity bands, not anatomical segmentations. High density must not be read as segmented bone.
