A Positron Range Correction with Texture Preservation Framework in PET Imaging
Nerea Encina-Baranda, Yifan Zheng, Jorge Cabello +5
Positron range (PR) blurring is a fundamental resolution limitation in PET imaging with high-energy positron emitters such as 82Rb, causing contrast loss and spill-out effects acro…
A tissue-informed deep learning-based method for positron range correction in preclinical 68Ga PET imaging
Nerea Encina-Baranda, Robert J. Paneque-Yunta, Javier Lopez-Rodriguez +5
Positron range (PR) limits spatial resolution and quantitative accuracy in PET imaging, particularly for high-energy positron-emitting radionuclides like 68Ga. We propose a deep le…
Stationary CT Imaging of Intracranial Hemorrhage with Diffusion Posterior Sampling Reconstruction
Alejandro Lopez-Montes, Thomas McSkimming, Anthony Skeats +4
Diffusion Posterior Sampling (DPS) can be used in Computed Tomography (CT) reconstruction by leveraging diffusion-based generative models for unconditional image synthesis while ma…
Data-driven Improved Sampling in PET
Pablo Galve, Alejandro Lopez-Montes, Jose M Udias +2
Positron Emission Tomography (PET) scanners are usually designed with the goal to obtain the best compromise between sensitivity, resolution, field-of-view size, and cost. Therefor…
