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 ...

3D microwave tomography with huber regularization applied to realistic numerical breast phantoms [PDF]

, 2016
Quantitative active microwave imaging for breast cancer screening and therapy monitoring applications requires adequate reconstruction algorithms, in particular with regard to the nonlinearity and ill-posedness of the inverse problem.

Materials for phantoms for terahertz pulsed imaging [PDF]

, 2004
Phantoms are commonly used in medical imaging for quality assurance, calibration, research and teaching. They may include test patterns or simulations of organs, but in either case a tissue substitute medium is an important component of the phantom.

New mesh-type phantoms and their dosimetric applications, including emergencies

Annals of the ICRP, 2018
Committee 2 of the International Commission on Radiological Protection (ICRP) has constructed mesh-type adult reference computational phantoms by converting the voxel-type ICRP Publication 110 adult reference computational phantoms to a high-quality mesh

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.

Advances in digital and physical anthropomorphic breast phantoms for x-ray imaging.

Medical Physics (Lancaster), 2018
PURPOSE With the advent of three-dimensional (3D) breast imaging modalities such as digital breast tomosynthesis (DBT) and dedicated breast CT (bCT), research into new anthropomorphic breast phantoms has accelerated.
