Constraints on Scalar Phantoms
, 2010 We update the constraints on the minimal model of dark matter, where a stable real scalar field is added to the standard model Lagrangian with a renormalizable coupling to the Higgs field.

Spherical deconvolution of multichannel diffusion MRI data with non-Gaussian noise models and spatial regularization [PDF]
, 2015 Spherical deconvolution (SD) methods are widely used to estimate the intra-voxel white-matter fiber orientations from diffusion MRI data. However, while some of these methods assume a zero-mean Gaussian distribution for the underlying noise, its real ...

Complementary Phenomena: Phantom Hand and Phantom Face
Cognitive and Behavioral Neurology, 2021 After tissue or limb loss, the development of sensation and perception of the lost or deafferent tissue is defined as a phantom phenomenon. We investigated the presence of phantom phenomena in individuals who underwent a full face transplant as well as those who had a hand transplant.

Preclinical dosimetry: exploring the use of small animal phantoms
Radiation Oncology, 2019 Preclinical radiotherapy studies using small animals are an indispensable step in the pathway from in vitro experiments to clinical implementation. As radiotherapy techniques advance in the clinic, it is important that preclinical models evolve to keep ...

Anatomically realistic ultrasound phantoms using gel wax with 3D printed moulds
Physics in Medicine and Biology, 2018 Here we describe methods for creating tissue-mimicking ultrasound phantoms based on patient anatomy using a soft material called gel wax. To recreate acoustically realistic tissue properties, two additives to gel wax were considered: paraffin wax to ...

Feasibility of MV CBCT-based treatment planning for urgent radiation therapy: dosimetric accuracy of MV CBCT-based dose calculations. [PDF]
, 2015 Unlike scheduled radiotherapy treatments, treatment planning time and resources are limited for emergency treatments. Consequently, plans are often simple 2D image-based treatments that lag behind technical capabilities available for nonurgent ...
