Anthropomorphic Polydimethylsiloxane silicone-based phantom for Diffuse Optical Imaging

open access: yesHeliyon, 2022
This work presents a method for constructing phantoms suitable for diffuse optical mammography. They are based on Polydimethylsiloxane silicones, with the characteristic of being anthropomorphic, and having similar mechanical and optical properties as a ...

A moving liver phantom in an anthropomorphic thorax for SPECT MP imaging [PDF]

open access: yesPhysical and Engineering Sciences in Medicine, 2021
Abstract Cranio-caudal respiratory motion and liver activity cause a variety of complex myocardial perfusion (MP) artifacts, especially in the inferior myocardial wall, that may also mask cardiac defects. To assess and characterise such artifacts, an anthropomorphic thorax with moving thoracic phantoms can be utilised in SPECT MP ...

Anthropomorphic Image Reconstruction via Hypoelliptic Diffusion [PDF]

open access: yesSIAM Journal on Control and Optimization, 2012
In this paper we study a model of geometry of vision due to Petitot, Citti and Sarti. One of the main features of this model is that the primary visual cortex V1 lifts an image from $R^2$ to the bundle of directions of the plane. Neurons are grouped into orientation columns, each of them corresponding to a point of this bundle.

Anthropomorphic Breast and Head Phantoms for Microwave Imaging [PDF]

open access: yesDiagnostics, 2018
This paper deals with breast and head phantoms fabricated from 3D-printed structures and liquid mixtures whose complex permittivities are close to that of the biological tissues within a large frequency band. The goal is to enable an easy and safe manufacturing of stable-in-time detailed anthropomorphic phantoms dedicated to the test of microwave ...

Stereotactic Imaging Quality Assurance Using an Anthropomorphic Phantom [PDF]

open access: yesComputer Aided Surgery, 1999
A custom-designed anthropomorphic head phantom, containing computed tomography (CT) and magnetic resonance (MR) viewable targets, was used in the assessment of stereotactic localization accuracy.The Brown-Roberts-Wells (BRW) or Leksell stereotactic ring was rigidly fixed to the phantom.

Anthropomorphic Calcaneus Phantom for Microwave Bone Imaging Applications

open access: yesIEEE Journal of Electromagnetics, RF and Microwaves in Medicine and Biology, 2021
Recent studies have found a significant dielectric contrast between healthy and osteoporotic human trabecular bones. This dielectric contrast can be exploited by microwave imaging for monitoring human bone health. The tissue mimicking phantoms play a vital role for preclinical testing of microwave imaging system.

ANTHROPOMORPHIC IMAGES ON POTTERY OF THE SAMOSDELKA SETTLEMENT

open access: yesHistory, Archeology and Ethnography of the Caucasus, 2023
The Samosdelka fortified settlement, located in the center of the Volga delta, dates back to the 9th – the first half of the 14th century. The study aims to introduce anthropomorphic images on unglazed and glazed vessels found during excavations of this site.

Development of an Anthropomorphic Phantom of the Axillary Region for Microwave Imaging Assessment [PDF]

open access: yesSensors, 2020
We produced an anatomically and dielectrically realistic phantom of the axillary region to enable the experimental assessment of Axillary Lymph Node (ALN) imaging using microwave imaging technology. We segmented a thoracic Computed Tomography (CT) scan and created a computer-aided designed file containing the anatomical configuration of the axillary ...

Impact of Iterative Bilateral Filtering on the Noise Power Spectrum of Computed Tomography Images

open access: yesAlgorithms, 2022
A bilateral filter is a non-linear denoising algorithm that can reduce noise while preserving the edges. This study explores the characteristics of a bilateral filter in changing the noise and texture within computed tomography (CT) images in an ...

Anthropomorphic breast phantoms for radiology imaging: a review

open access: yesDigital Diagnostics, 2023
Phantoms are used to validate diagnostic imaging methods or improve the skills of medical professionals. For instance, they allow conducting an unlimited number of imaging studies during medical training, assessing image quality, optimizing radiation dose, and testing novel techniques and equipment.
