Development of 3D-Printed Heterogeneous Tumour Phantom for Quantitative Analysis in PET/CT Imaging [PDF]
MATEC Web of Conferences, 2021 Tumours are heterogenous growths that consists of different types of cells with varying genetic expressions. The complex structure of the tumour makes cancer treatment difficult due to the heterogeneity of each of the cancer cells that react differently ...

Optimization of 2D CT Data Sets for Three-Dimensional [PDF]
, 1993 Computer-generated anatomic modeling using radiologic data is a well-known entity. Currently, state of the art 3D modeling systems lack the variable thresholding, user interactive, capabilities of 3D imaging software.1 We investigated clinical ...

Organosilicon phantom for photoacoustic imaging
Journal of Biomedical Optics, 2015 Photoacoustic imaging is an emerging technique. Although commercially available photoacoustic imaging systems currently exist, the technology is still in its infancy. Therefore, the design of stable phantoms is essential to achieve semiquantitative evaluation of the performance of a photoacoustic system and can help optimize the properties of contrast ...

EchoFusion: Tracking and Reconstruction of Objects in 4D Freehand Ultrasound Imaging without External Trackers [PDF]
, 2018 Ultrasound (US) is the most widely used fetal imaging technique. However, US images have limited capture range, and suffer from view dependent artefacts such as acoustic shadows. Compounding of overlapping 3D US acquisitions into a high-resolution volume

Developing a Phantom for the Positronium Imaging Evaluation
Acta 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.

Materials for phantoms for terahertz pulsed imaging [PDF]
Physics in Medicine and Biology, 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. The aim of this work was to identify materials suitable for use as tissue substitutes for the relatively
