Anthropomorphic Breast and Head Phantoms for Microwave Imaging
Diagnostics, 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.

Imaging and dosimetric study on direct flat-panel detector-based digital mammography system
Journal of Medical Physics, 2018 Introduction: Image quality of digital mammography system is generally defined by three primary physical parameters, namely, contrast, resolution, and noise.

Indian Journal of Surgery, 2012 Right upper quadrant abdominal pain may be due to many causes, and at times may give rise to diagnostic dilemma. We present here a young lady with biliary type of pain who was eventually found to have gall bladder agenesis with aerobilia, in the absence of prior biliary intervention.

Optical phantoms for biomedical polarimetry: a review
Journal of Biomedical Optics, 2019 . Calibration, quantification, and standardization of the polarimetric instrumentation, as well as interpretation and understanding of the obtained data, require the development and use of well-calibrated phantoms and standards. We reviewed the status of

A feasible and automatic free tool for T1 and ECV mapping [PDF]
, 2017 Purpose: Cardiac magnetic resonance (CMR) is a useful non-invasive tool for characterizing tissues and detecting myocardial fibrosis and edema. Estimation of extracellular volume fraction (ECV) using T1 sequences is emerging as an accurate biomarker in ...

Effect of Spatial Modulated Light on Position of Self-Calibration Point
IEEE Photonics Journal, 2021 In optical sensing, the differentiation between absorption and scattering poses a challenge when dealing with a physiological medium. We have shown that for extracting absorption-based parameters it is optimal to measure at the iso-path length (IPL ...

Phantom hCG and Phantom Choriocarcinoma
Gynecologic Oncology, 1998 Phantom hCG and phantom choriocarcinoma syndrome (pseudohypergonadotropinemia) refers to persistent mild elevations of hCG, leading physicians to treat patients with cytotoxic chemotherapy for choriocarcinoma when in reality no true hCG or trophoblast disease is present. We report here three cases of the phantom hCG and phantom choriocarcinoma syndrome

Crossing the phantom divide without phantom matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2006 A class of braneworld models can lead to phantom-like acceleration of the late universe, but without the need for any phantom matter. In the simplest models, the universe contains only cold dark matter and a cosmological constant. We generalize these models by introducing a quintessence field. The new feature in our models is that quintessence leads to
