Summary
Brief summary (as posted)
This is a single centre, single arm feasibility study assessing the feasibility of using computer vision methods to recreate the 3D bladder shape and to then map the cystoscopy images onto this bladder shape. If feasible, this 3D reconstructed shape would be spatially registered to radiological images (CT, MR) that are then used during radiation treatment planning. This analysis would not be used for making any clinical treatment decisions on the patient.
