The effect of spatial resolution on the reproducibility of diffusion imaging when controlled signal to noise ratio

Biomedical Journal, 2019
Background: The purpose of the study is to evaluate the reproducibility and repeatability of the compartmental diffusion measurement. Methods: Two identical whipping cream phantoms and two healthy Sprague–Dawley rats were scanned on a 7T MR scanner, each

Digital mouse phantom for optical imaging

Journal of Biomedical Optics, 2007
We present a method for design and use of a digital mouse phantom for small animal optical imaging. We map the boundary of a mouse model from magnetic resonance imaging (MRI) data through image processing algorithms and discretize the geometry by a finite element (FE) descriptor.

Quantifying Cross-scatter Contamination in Biplane Fluoroscopy Motion Analysis Systems [PDF]

, 2015
Biplane fluoroscopy is used for dynamic in vivo three-dimensional motion analysis of various joints of the body. Cross-scatter between the two fluoroscopy systems may limit tracking accuracy. This study measured the magnitude and effects of cross-scatter

Real-time delay-multiply-and-sum beamforming with coherence factor for in vivo clinical photoacoustic imaging of humans [PDF]

, 2019
In the clinical photoacoustic (PA) imaging, ultrasound (US) array transducers are typically used to provide B-mode images in real-time. To form a B-mode image, delay-and-sum (DAS) beamforming algorithm is the most commonly used algorithm because of its ...

Screen-printed flexible MRI receive coils. [PDF]

, 2016
Magnetic resonance imaging is an inherently signal-to-noise-starved technique that limits the spatial resolution, diagnostic image quality and results in typically long acquisition times that are prone to motion artefacts.

Personalized Selumetinib Dosing in Pediatric Neurofibromatosis Type 1: Insights From a Pilot Therapeutic Drug Monitoring Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate selumetinib exposure using therapeutic drug monitoring (TDM) in pediatric patients with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PN), assess interpatient pharmacokinetic variability, and explore the relationship between drug exposure, clinical response, and adverse effects.

Estimating Effective Diameter and Scan Length of Abdomen and Pelvis for Radiation Dose Optimization in Computed Tomography Imaging Suitable for the Indian Population – A Preliminary Study

National Journal of Clinical Anatomy
Background: Utilization of computed tomography (CT) has dramatically increased during the last decade with a concurrent increase in exposure to ionizing radiation. Even low levels of exposure have been linked to the development of cancer.

Quantitative evaluation of an optimized Time of Flight Magnetic Resonance Imaging procedure using a phantom setup to simulate aqueous humor flow

Data in Brief, 2018
Preclinical Magnetic Resonance Imaging at high field strength offers the great advantage of combining anatomical information and very high resolution of down to 25 µm in mice and even higher resolutions in ex vivo settings.
