PET Image Deblurring and Super-Resolution With an MR-Based Joint Entropy Prior

The intrinsically limited spatial resolution of positron emission tomography (PET) confounds image quantitation. This paper presents an image deblurring and super-resolution framework for PET using anatomical guidance provided by high-resolution magnetic resonance (MR) images. The framework relies on image-domain postprocessing of already-reconstructed PET images by means of spatially variant deconvolution stabilized by an MR-based joint entropy penalty function.

Accurate Multi-Material Decomposition in Dual-Energy CT: A Phantom Study

DUAL-energy computed tomography (DECT) differentiates materials by exploiting the varying material linear attenuation coefficients (LACs) for different x-ray energy spectra. Multi-material decomposition (MMD) is a particularly attractive DECT clinical application to distinguish the complicated material components within the human body. 

SPS Announces 2020 Class of Distinguished Lecturers and Distinguished Industry Speakers

The IEEE Signal Processing Society (SPS) announced the 2020 Class of Distinguished Lecturers and Distinguished Industry Speakers for the term of 1 January 2020 to 31 December 2021, which are noted below.  The IEEE SPS Distinguished Lecturer (DL) Program provides a means for Chapters to have access to well-known educators and authors in the fields of signal processing to lecture at Chapter meetings. 

IEEE SPS 2019 President-Elect, Members-at-Large, and Regional Directors-at-Large Election Results

Beginning this year, all eligible IEEE Signal Processing Society Members were able to cast their vote for the next IEEE Signal Processing Society President-Elect. The President-Elect will sit on the IEEE Signal Processing Society Board of Governors beginning 1 January 2020 and will serve until 31 December 2021, when they will be elevated to Society President.
