3D Convolutional Neural Network to Enhance Small-Animal Positron Emission Tomography Images in the Sinogram Domain
Vergara Villegas, Osslan Osiris (Springer, 2022-06-11)In this work, we propose a three dimensional (3D) convolutional neural network (CNN) to enhance sinograms acquired from a small-animal positron emission tomography (PET) scanner. The network consists of three convolutional ... -
An Improved Method for Optical Characterization of Mineral Dust and Soot Particles in the El Paso-Juárez Airshed
Polanco Gonzalez, Javier (2020-08-15)Highly time-resolved aerosol measurements and analysis are necessary for a proper aerosol characterization in many polluted regions, because aerosol concentrations in polluted environments can change over time scales of ... -
On the Electronic Structure of 2H-MoS2: Correlating DFT Calculations and In-Situ Mechanical Bending on TEM
Ramos Murillo, Manuel Antonio (2022-09-28)We present a systematic density functional theory study to determine the electronic structure of bending 2H-MoS2 layers up to 75deg using information from in-situ nanoindentation TEM observations. The results from HOMO/LUMO ... -
Residual 3D convolutional neural network to enhance sinograms from small-animal positron emission tomography images
Ochoa Domínguez, Humberto; Vergara Villegas, Osslan Osiris; Cruz Sanchez, Vianey Guadalupe; Polanco Gonzalez, Javier; 194726; Rodríguez, Leandro José; Sossa, Juan Humberto (2023-05-05)Positron emission tomography (PET) has been widely used in nuclear medicine to diagnose cancer. PET images suffer from degradation because of the scanner’s physical limitations, the radiotracer’s reduced dose, and the ...
