Localise to segment: crop to improve organ at risk segmentation accuracy

1 code implementation10 Apr 2023 Abraham George Smith, Denis Kutnár, Ivan Richter Vogelius, Sune Darkner, Jens Petersen

Some deep learning methods for the segmentation of organs at risk use a two stage process where a localisation network first crops an image to the relevant region and then a locally specialised network segments the cropped organ of interest.

Deep Learning-Assisted Localisation of Nanoparticles in synthetically generated two-photon microscopy images

no code implementations17 Mar 2023 Rasmus Netterstrøm, Nikolay Kutuzov, Sune Darkner, Maurits Jørring Pallesen, Martin Johannes Lauritzen, Kenny Erleben, Francois Lauze

Low signal-to-noise ratios, movement of molecules out-of-focus, and high motion blur on images recorded with scanning two-photon microscopy (2PM) in vivo pose a challenge to the accurate localisation of molecules.

A Hybrid Approach to Full-Scale Reconstruction of Renal Arterial Network

no code implementations3 Mar 2023 Peidi Xu, Niels-Henrik Holstein-Rathlou, Stinne Byrholdt Søgaard, Carsten Gundlach, Charlotte Mehlin Sørensen, Kenny Erleben, Olga Sosnovtseva, Sune Darkner

The renal vasculature, acting as a resource distribution network, plays an important role in both the physiology and pathophysiology of the kidney.

cRedAnno+: Annotation Exploitation in Self-Explanatory Lung Nodule Diagnosis

2 code implementations28 Oct 2022 Jiahao Lu, CHONG YIN, Kenny Erleben, Michael Bachmann Nielsen, Sune Darkner

Recently, attempts have been made to reduce annotation requirements in feature-based self-explanatory models for lung nodule diagnosis.

Reducing Annotation Need in Self-Explanatory Models for Lung Nodule Diagnosis

2 code implementations27 Jun 2022 Jiahao Lu, CHONG YIN, Oswin Krause, Kenny Erleben, Michael Bachmann Nielsen, Sune Darkner

Visualisation of the learned space further indicates that the correlation between the clustering of malignancy and nodule attributes coincides with clinical knowledge.

First Order Locally Orderless Registration

no code implementations10 Aug 2021 Sune Darkner, Jose D Tascon, Francois Lauze

First Order Locally Orderless Registration (FLOR) is a scale-space framework for image density estimation used for defining image similarity, mainly for Image Registration.

RootPainter3D: Interactive-machine-learning enables rapid and accurate contouring for radiotherapy

1 code implementation22 Jun 2021 Abraham George Smith, Jens Petersen, Cynthia Terrones-Campos, Anne Kiil Berthelsen, Nora Jarrett Forbes, Sune Darkner, Lena Specht, Ivan Richter Vogelius

Organ-at-risk contouring is still a bottleneck in radiotherapy, with many deep learning methods falling short of promised results when evaluated on clinical data.

Information-Theoretic Registration with Explicit Reorientation of Diffusion-Weighted Images

1 code implementation28 May 2019 Henrik Grønholt Jensen, François Lauze, Sune Darkner

We present an information-theoretic approach to the registration of images with directional information, and especially for diffusion-Weighted Images (DWI), with explicit optimization over the directional scale.

A Statistical Model for Simultaneous Template Estimation, Bias Correction, and Registration of 3D Brain Images

no code implementations1 May 2017 Akshay Pai, Stefan Sommer, Lars Lau Raket, Line Kühnel, Sune Darkner, Lauge Sørensen, Mads Nielsen

Template estimation plays a crucial role in computational anatomy since it provides reference frames for performing statistical analysis of the underlying anatomical population variability.
