In 2018, Mevion and RaySearch's collaborative partnership enabled layer-by-layer collimation
with the Adaptive Aperture pMLC as part of the RayStation 8B release, leading to the first-in-the-world clinical implementation of this capability.
PowerPhotonic has released a range of freeform Field Mapper SAC (FM-SAC) optics, to provide both slow axis collimation
and fast axis beam shaping in a single optical element, improving diode laser pump efficiency.
Amada's Auto Collimation
technology is a further stand-out feature of the new machines, as it delivers exceptional beam diameter and focus-point control for high cutting speeds and surface quality, reducing the need for secondary finishing operations.
According to the company, RayStation enables the use of advanced IMPT capabilities that are unique to the Hyperscan technology, including multi-leaf collimation
with Mevion's Adaptive Aperture, a proton multi-leaf collimator (pMLC) designed to achieve sharp lateral dose gradients and protect sensitive organs at every energy layer of the treatment.
The two regions bookend the acceleration and collimation
zone, a poorly understood space where the jet's plasma narrows and achieves relativistic speeds.
In this paper, we present a novel system, using simulated collimation
, Holographic Optical Elements and spectral interferential filters.
It is prevalent when imaging thicker anatomy and when collimation
is not close enough to the anatomy of interest.
It is equipped with many dose reduction features, including an integrated laser light localizer, radiation free collimation
, and multi-level dose control.
(1,2) As a result, dentistry has tried to minimize patient dose through the use of patient protective equipment, faster receptors, digital imaging, beam alignment devices, longer source to end distances and collimation
of the beam.
Procedures--Sets of radiographs were prospectively collected and evaluated for proper performance of various radiographic technical variables including exposure, collimation
, positioning, inclusion of all appropriate views, presence of artifacts, radiation safety, and labeling.
The topics include applications of propagation invariant light fields, linearly traveling and accelerating localized wave solutions to the Schrodinger and Schrodinger-like equations, low-cost two-dimensional collimation
of real-time pulsed ultrasonic beams by X-wave-based high-voltage driving of annular arrays, generating localized beams and localized pulses using the angular spectrum, and controlling the longitudinal and transverse shape of optical non-diffracting waves in the experimental generation of frozen waves in optics.
