Weak lensing flexion as a probe of galaxy cluster substructure

Cain, Benjamin MartinMassachusetts Institute of Technology2011

… on measuring derived properties of the lensed images, such as shapelet coefficients or surface brightness moments, my method fits a fully mass-sheet-invariant parametrized Analytic Image Model (AIM) to the each galaxy image. This simple parametric model traces the distortion of lensed image …

Simultaneous ⁹⁹m̳Tc-MDP/¹²³I-MIBG imaging of neuroblastoma using SPECT-CT

Pérez-Gutiérrez, José P. (José Pablo Andrés)Massachusetts Institute of Technology2011

… These factors hinder the separation of images of these two radionuclides. An enhanced fast Monte Carlo based joint ordered-subset expectation maximization (MC-JOSEM) reconstruction algorithm has been been developed for simultaneous ⁹⁹m̳Tc/¹²³ imaging by Ouyang, El Fakhri, and Moore …
