Noise reduction on mammographic phantom images [PDF]

open access: yesELCVIA Electronic Letters on Computer Vision and Image Analysis, 2006
A noise reduction scheme on digitized mammographic phantom images is presented. This algorithm is based on a direct contrast modification method using an optimal function which is obtained by means of the mean squared error as a criterion. Computer simulated images containing objects similar to those observed in the phantom are built to evaluate the ...

Classification of phantoms for medical imaging

open access: yesProcedia CIRP, 2023
Phantoms are physical models that mimic biological tissue and its properties in medical imaging. They play an important role in medical quality assurance, research, education, and training, since they can offer an adequate test environment. As the use of medical imaging modalities is a growing field in medicine phantoms are likewise evolving very ...

Developing a Phantom for the Positronium Imaging Evaluation

open access: yesActa Physica Polonica B Proceedings Supplement, 2022
In this contribution, a concept for a new phantom for positronium imaging with PET scanners is described. The proposed phantom is based on the NEMA IEC phantom in which six high-activity spheres are filled with solutions characterized by a different mean ortho-positronium lifetime.

Tissue mimicking phantoms for fluorescence imaging [PDF]

open access: yesSaratov Fall Meeting 2019: Optical and Nano-Technologies for Biology and Medicine, 2020
The article describes the development of the optical phantom mimicking flavin adenine dinucleotide (FAD) and skin collagen fluorescence. The results of experimental studies using fluorescence imaging and fluorescence spectroscopy methods are demonstrated. The method of optical phantom production for quick calibration of fluorescence imaging devices for

Image of a regular phantom compact object and its luminosity under spherical accretions [PDF]

open access: yesClass.Quantum Grav. 38, 115008 (2021), 2020
We have studied the shadow and its luminosity for a static and regular phantom compact object under the static spherical accretion and the infalling spherical accretion, respectively. Comparing with the usual Schwarzschild black hole, the presence of phantom hair yields the larger black hole shadow and the darker image.
