Abstract:PurposeThe objective of this work is to outline a framework for dosimetric characterization that will comprehensively detail the clinical commissioning steps for 3D‐printed materials applied as patient support or immobilization devices in photon radiotherapy. The complex nature of 3D‐printed materials with application to patient‐specific configurations requires careful consideration. The framework presented is generalizable to any 3D‐printed object where the infill and shell combinations are unknown.MethodsA r… Show more
“…Within a study on headrests for Stereotactic Radio Surgery (SRS), 3D printed headrests had higher transmittance (98.89%) than standard SRS headrests (98.51%) [33]. Two studies demonstrated a methodology to measure beam attenuation with variable thickness and infill patterns [10,43].…”
Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD).
Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD.
The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC).
Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…The 3D-printed plastic plates enable the peak dose in the mini-beam dose profile. Thanks to the fast prototyping of the 3D-printing technology, [22][23][24] it was not only possible to create several plastic plates with different thicknesses and angles to change FWHM and ctc as well as compensate for beam divergence but also to design mounting setups for reproducible positioning of the mini-beam collimator in the MultiRad. The relevance of aligning the mini-beam collimator properly in the center of the X-ray radiation field is illustrated in Figure S7.…”

“…After evaluating the print accuracy, the masks were additively manufactured on the extrusion-based 3D printer Evolizer (EVO-tech GmbH, Schörfling, Austria). As material, acrylonitrile butadiene styrene (ABS), a standard 3D-printing filament, was used, as several studies have identified it as suitable for this application, also considering the attenuation properties [ 14 , 20 , 24 , 25 ].
