Towards Learning Contrast Kinetics with Multi-Condition Latent Diffusion Models

1 code implementation20 Mar 2024 Richard Osuala, Daniel Lang, Preeti Verma, Smriti Joshi, Apostolia Tsirikoglou, Grzegorz Skorupko, Kaisar Kushibar, Lidia Garrucho, Walter H. L. Pinaya, Oliver Diaz, Julia Schnabel, Karim Lekadir

Contrast agents in dynamic contrast enhanced magnetic resonance imaging allow to localize tumors and observe their contrast kinetics, which is essential for cancer characterization and respective treatment decision-making.

Pre- to Post-Contrast Breast MRI Synthesis for Enhanced Tumour Segmentation

1 code implementation17 Nov 2023 Richard Osuala, Smriti Joshi, Apostolia Tsirikoglou, Lidia Garrucho, Walter H. L. Pinaya, Oliver Diaz, Karim Lekadir

Despite its benefits for tumour detection and treatment, the administration of contrast agents in dynamic contrast-enhanced MRI (DCE-MRI) is associated with a range of issues, including their invasiveness, bioaccumulation, and a risk of nephrogenic systemic fibrosis.

How to cheat with metrics in single-image HDR reconstruction

1 code implementation19 Aug 2021 Gabriel Eilertsen, Saghi Hajisharif, Param Hanji, Apostolia Tsirikoglou, Rafal K. Mantiuk, Jonas Unger

Here, we reproduce a typical evaluation using existing as well as simulated SI-HDR methods to demonstrate how different aspects of the problem affect objective quality metrics.

Ensembles of GANs for synthetic training data generation

no code implementations23 Apr 2021 Gabriel Eilertsen, Apostolia Tsirikoglou, Claes Lundström, Jonas Unger

This work investigates the use of synthetic images, created by generative adversarial networks (GANs), as the only source of training data.

A Study of Deep Learning Colon Cancer Detection in Limited Data Access Scenarios

no code implementations20 May 2020 Apostolia Tsirikoglou, Karin Stacke, Gabriel Eilertsen, Martin Lindvall, Jonas Unger

One such scenario relates to detecting tumor metastasis in lymph node tissue, where the low ratio of tumor to non-tumor cells makes the diagnostic task hard and time-consuming.

Procedural Modeling and Physically Based Rendering for Synthetic Data Generation in Automotive Applications

no code implementations17 Oct 2017 Apostolia Tsirikoglou, Joel Kronander, Magnus Wrenninge, Jonas Unger

We present an overview and evaluation of a new, systematic approach for generation of highly realistic, annotated synthetic data for training of deep neural networks in computer vision tasks.
