Alpha-SPECT work at Fully 3D meeting: Best oral award nominee

Alpha-SPECT work at Fully 3D meeting: Best oral award nominee
Excited to share that our own Zekun Li will be presenting our work on developing a multi-energy window quantitative SPECT method for joint quantification of Thorium and Radium! This work is a candidate for the best oral award nominee! https://www.conftool.pro/fully3d-2021/index.php?page=browseSessions&presentations=show&search=A+multiple-energy-window+projection-domain+quantitative+SPECT+method+for+joint+regional+uptake+quantification+of+Th-227+and+Ra-223  

Pre-print: Quantitative SPECT method for alpha-particle therapies

Pre-print: Quantitative SPECT method for alpha-particle therapies
We posted a new pre-print that proposes and evaluates a projection-domain low-count quantitative SPECT method for alpha-particle emitting radiopharmaceutical therapy. The proposed method yields accurate significantly improved performance compared to state-of-the-art  methods for quantitative SPECT. Link here.

New publication on estimation-based PET segmentation

New publication on estimation-based PET segmentation
Our article on an estimation-based approach to segmenting PET images has been published in the Special issue on Early Career Researchers in Physics and Medicine and Biology! This article approaches a new approach to segmentation that accounts for the partial-volume effects, including the tissue-fraction effects in PET. Link to article here: https://iopscience.iop.org/article/10.1088/1361-6560/ac01f4/meta A press release […]

Four talks highlighted at SNMMI 2020!
Delighted to share that the four abstracts we had submitted to the SNMMI 2020 Annual Meeting were all accepted for talks and then also highlighted in the summary session of the PIDS council. The references are as below: 1. H.S. Moon, Z. Liu, M. Ponisio, R. Laforest, and A. K. Jha, A physics-guided and learning-based […]

Article on analysis of list-mode SPECT emission data accepted

Article on analysis of list-mode SPECT emission data accepted
Delighted to share that our article on analyzing the information content in SPECT emission data on the task of jointly estimating activity and attenuation distribution was accepted to Inverse Problems. Link to the article is here. Arxiv link here. This work shows that scatter-window photons in SPECT, that are typically discarded, when acquired in list-mode […]

Article on physics-guided AI-based segmentation method accepted

Article on physics-guided AI-based segmentation method accepted
Excited to share that our article on developing a modular physics-guided deep-learning-based method for segmenting oncological PET images was recently accepted to the journal Physics in Medicine and Biology. Here is the link to the article, and here is the arxiv link. The article was also highlighted in the McKelvey Engineering newsletter. Source code for […]

Hae Sol defends his thesis

Hae Sol defends his thesis
Congratulations to Hae Sol on defending his thesis on developing new image-analysis methods for DaTscan SPECT. His committee consisted of Drs. Joel Perlmutter, Richard Laforest, Dennis Barbour, and Abhinav Jha. Hae Sol is the first Masters student to defend from the lab. Exciting times!
