Paul Friedrich

I am a second year PhD student at the Center for medical Image Analysis and Navigation (CIAN) of the University of Basel. My work is supervised by Philippe Cattin and Florian Thieringer. I hold a bachelor's and a master's degree in biomedical engineering, both of which I finished best in class.

Research

I'm interested in medical image analysis, computer vision, 3D deep learning and generative models. My current research is part of the MIRACLE II project and focuses on conditional shape generation and manipulation tasks as well as medical image generation.

Cattin MICCAI, 2024 Code / arXiv A Bernoulli Diffusion Model operating on a binary latent representation of the data to effectively solve an unsupervised anomaly detection task.
	WDM: 3D Wavelet Diffusion Models for High-Resolution Medical Image Synthesis Paul Friedrich, Julia Wolleb, Florentin Bieder, Alicia Durrer, Philippe C. Cattin arXiv preprint, 2024 Project page / Code / Models / arXiv WDM is a framework for high-resolution medical images synthesis. We propose a simple yet effective way of scaling 3D diffusion models to high resolutions (256 x 256 x 256 on a single 40 GB GPU) by applying Discrete Wavelet Transform for spatial dimensionality reduction.

You can search, display them in 3D and download the individual shapes by using our shape search engine.
	Point Cloud Diffusion Models for Automatic Implant Generation Paul Friedrich, Julia Wolleb, Florentin Bieder, Florian M. Thieringer, Philippe C. Cattin MICCAI, 2023 Project page / Code / arXiv / Paper / YouTube Following the recent success of diffusion models, we propose a novel approach for automatic implant generation based on a combination of 3D point cloud diffusion models and voxelization networks. Due to the non-deterministic sampling process in our diffusion model, we can propose an ensemble of different implants per defect, from which the physicians can choose the most suitable one.
