What this is, and is not

ProstateView is a research and educational prototype built by Nityanandan G (ST4 Urology, Mersey Deanery) as part of the wider UroRef Companion Viewer programme. It takes a prostate mpMRI from a public research dataset and produces a 3D model intended for orientation, teaching, and pre-procedural visualisation in cognitive-fusion biopsy education.

What it is

• A teaching aid for trainees learning prostate zonal anatomy and PI-RADS sector mapping.
• A demonstrator for the AIiH 2026 abstract and RISE-UK 2026 demo.
• A starting point for the NHS CEP Cohort 11 evaluation framing.

What it is not

• A medical device. It carries no MHRA/UKCA conformity assessment and must not be used in clinical care.
• A PI-RADS predictor. The score is recorded from the radiologist - never inferred by the model.
• A biopsy guide. Real biopsies use validated, regulated tooling.

How segmentation is framed

Whole-gland and zonal masks come from MONAI's Prostate158-trained bundle, which is the cleanest open option for separable peripheral- and transition-zone output. Lesion segmentation is the weakest part of the pipeline (Dice around 0.45 on public benchmarks) and is explicitly flagged as low-confidence on every view. Where the model exposes uncertainty we surface it; where it does not we do not invent it.

Data handling

Only public research datasets (PI-CAI, ProstateX, Promise12, Prostate158) are permitted. Every upload runs a DICOM PS 3.15 Annex E PHI strip and writes an audit log of every tag removed. No NHS patient data, no Leighton or BCUHB scans.

Regulatory framing

The path to clinical use is documented in docs/REGULATORY.md in the repository: UK MDR 2002 (Class IIa software pathway), ISO 13485, ISO 14971, IEC 62304, IEC 62366, plus NHS CEP and DTAC. ProstateView is currently outside that envelope by design.
