We describe a new approach to the problem of collimator optimization in nuclear medicine; our methodology is illustrated for the challenging case of gallium-67 imaging. Collimator-design methods based ...

At the core of an OCS, 2D Collimator Array by Coherent is essential for enabling matrix optical signal switching, integrating a 2D lens array and a 2D fiber array.

ORNL 3D prints 'Frankenstein' neutron collimator. The multi-part design, produced using binder jetting, will be used for neutron scattering.

The time-tested strategy of divide and conquer took on a new, high-tech meaning during neutron experiments by scientists at the Department of Energy’s Oak Ridge National Laboratory. They discovered ...

A new design of collimator is proposed that has variable sensitivity and spatial resolution, eliminating the need for exchanging collimators in a gamma camera. Using Monte Carlo simulations, the ...

In the experimental setting, a collimator is frequently employed to focus on a particular location of interest in the fuel. Predictive models for the transmitted gamma-ray intensity through the ...

MPH collimator provides a large improvement in sampling over the single pinhole collimator and LEHR, especially for fewer projections. MPH could resolve similar sizes of rods for 16–64 projections.

Sub-arc collimator angle optimization based on the conformity index heatmap for VMAT planning of multiple brain metastases SRS treatments ...

The performance of the collimator depends on the geometric transparency of the porous narrow channel of the collimator, the size and uniformity of each small hole, the thickness and strength of the ...
