Magnetic Needle Steering in Soft Phantom Tissue [PDF]
Scientific Reports, 2020 AbstractNeedle steering is a technology for guiding needles around sensitive internal obstacles in minimally invasive surgery. Traditional techniques apply rotation at the base of a needle with an asymmetric tip, enabling steering through the redirection of radial forces.

A tissue-equivalent phantom series for mammography dosimetry [PDF]
Journal of Applied Clinical Medical Physics, 2004 A breast tissue‐equivalent series (BRTES) of phantoms is manufactured to mimic both the attenuation and the density of the range of glandular and adipose tissue compositions encountered in mammography. The BRTES simulates breast tissues across the range of 20% to 70% glandularity and can be assembled in a variety of thicknesses to represent a ...

Radiation dose verification using real tissue phantom in modern radiotherapy techniques
Journal of Medical Physics, 2014 In vitro dosimetric verification prior to patient treatment has a key role in accurate and precision radiotherapy treatment delivery. Most of commercially available dosimetric phantoms have almost homogeneous density throughout their volume, while real ...

Filament material evaluation for breast phantom fabrication using three-dimensional printing [PDF]
Nuclear Technology and Radiation Protection, 2020 In this study, a method of directly evaluating the dose received by the highly radiation-sensitive mammary gland during mammography was investigated, and a corresponding breast phantom was produced that expresses a mammary gland, as an ...

Mapping the invisible hand: a body model of a phantom limb [PDF]
, 2012 After amputation, individuals often have vivid experiences of their absent limb (i.e., a phantom limb). Therefore, one’s conscious image of one’s body cannot depend on peripheral input only (Ramachandran & Hirstein, 1998).

Soft-Tissue-Mimicking Using Hydrogels for the Development of Phantoms [PDF]
Gels, 2022 With the currently available materials and technologies it is difficult to mimic the mechanical properties of soft living tissues. Additionally, another significant problem is the lack of information about the mechanical properties of these tissues. Alternatively, the use of phantoms offers a promising solution to simulate biological bodies.
