Interactive viewer in Jupyter Notebook

Example of the IMPERANDI interactive viewer interface in a Jupyter Notebook.

class imperandi.qc.viewer.CTScanViewer(df, ct_scan_col, segmentation_cols=None, phase_col=None, HU_min=-100, HU_max=400, exploration_mode='ordered', isotropic_resolution_mm=1.0)

Bases: object

Interactive Jupyter viewer for CT volumes and segmentation overlays.

The viewer navigates cohort rows, patients, exams, phases, and anatomical planes while applying configurable HU windows and isotropic resampling.
