Article Synopsis
- * An innovative scatter correction method uses iterative deconvolution to estimate scattered photons in each pixel, significantly improving results over traditional techniques, especially in complex imaging scenarios.
- * Simulation studies indicate that this deconvolution method can recover up to 89% of contrast lost due to scattered photons, and its requirements for source and detector technology are becoming feasible for advanced imaging systems.
Introduction: Intersectoral collaboration is a collaborative approach between the health sectors and other sectors to address the interdependent nature of the social determinants of health associated with chronic diseases such as diabetes. This scoping review aims to identify intersectoral health interventions implemented in primary care and community settings to improve the well-being and health of people living with type 2 diabetes.
Methods And Analysis: This protocol is developed by the Arksey and O'Malley (2005) framework for scoping reviews and the Levac methodological enhancement.
Time-of-flight (TOF) scatter rejection allows for identifying and discarding scattered photons without the use of an anti-scatter grid (ASG). Although TOF scatter rejection was initially presented for cone-beam computed tomography, we propose, herein, to extend this approach to x-ray radiography. This work aims to evaluate with simulations if TOF scatter rejection can outperform ASGs for radiography.

We consider both positive and negative values of the higgsino mass parameter (μ). Our investigation shows that the recent experimental results from the LHC as well as from direct detection searches for dark matter by the LUX-ZEPLIN Collaboration rule out the Z-funnel region for the μ>0 scenario.

We sought to elucidate whether our local community blood supply is at increased susceptibility for transmission of transfusion-associated HEV infections.
Materials And Methods: We screened 10,002 randomly selected donations over an 8-month period between 2017 and 2018 at the Stanford Blood Center for markers of HEV infection using commercial IgM/IgG serological tests and reverse transcriptase quantitative polymerase chain reaction assays (RT-qPCR).
