Dynamic Heart Phantom for Electromagnetic Imaging

2022 International Symposium on Antennas and Propagation (ISAP), 2022
This paper presents the design of a dynamic heart phantom for developing functional electromagnetic imaging systems. The dynamic phantom provides a realistic simulation of both the electrical properties as well as the changes that occur over the course of a person's pulse.

Breast Phantoms for Microwave Imaging

IEEE Antennas and Wireless Propagation Letters, 2014
Herein, we study the dielectric properties of various mixtures susceptible to be used in manufacturing of reference inhomogeneous breast phantoms dedicated to the experimental validation of microwave breast imaging systems in the 0.5-6-GHz frequency range.

Anisotropic phantoms in Magnetic Resonance Imaging

2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015
Even though Magnetic Resonance Imaging (MRI) gives possibility to obtain qualitatively very good images, most quantitative results obtained by means of MRI are biased with high dependence on particular hardware parameters, imaging sequence used, and properties of analysed sample.

A real vessel phantom for imaging experimentation

Medical Physics, 1997
Vascular phantoms are used to evaluate imaging techniques such as ultrasound (US), CT, and angiography. They are expected to mimic the vasculature, surrounding tissue, and blood, and therefore must meet specific requirements on the mimicking materials, with respect to x‐ray attenuation and acoustic properties (velocity, attenuation).

Imaging CDMAM phantom with tomosynthesis

SPIE Proceedings, 2008
We studied the use of the mammography contrast detail phantom (CDMAM) with tomosynthesis to evaluate the performance of our system as well as to explore the application of CDMAM in 3D breast imaging. The system was Hologic's 1st generation tomosynthesis machine.

Modular open-source imaging phantom

ISMRM Annual Meeting
Motivation: Overcome the high cost, lack of customisation and low global uptake of standard MRI imaging phantoms. Goal(s): Design an affordable open-source MRI imaging phantom, imaging protocols and analysis tools demonstrated, showcasing their efficacy ...

Reference phantoms for microwave imaging

2017 11th European Conference on Antennas and Propagation (EUCAP), 2017
Microwave imaging offers an alternative modality for breast cancer screening and for the diagnosis of cerebrovascular accidents. Before clinical application, the performances of microwave imaging systems have to be assessed on anatomically detailed anthropomorphic phantoms.

Automatic Analysis of ACR Phantom Images in MRI

Current Medical Imaging Formerly Current Medical Imaging Reviews, 2020
Background: Quality Assurance (QA) of Magnetic Resonance Imaging (MRI) system is an essential step to avoid problems in diagnosis when image quality is low. It is considered a patient safety issue. The accreditation program of the American College of Radiology (ACR) includes a standardized image quality measurement protocol. However, it has been shown
