MR diffusion - "diffraction" phenomenon in multi-pulse-field-gradient experiments.
Using pulsed-field-gradient (PFG) experiments, the sizes of the pores in ordered porous media can be estimated from the "diffraction" pattern that the signal attenuation curves exhibit. A different diffraction pattern is observed when the experiment is extended to a larger number (N) of diffusion gradient pulse pairs. Simulations to calculate signal values from arbitrary gradient waveforms are ...
متن کاملMR Experiments Using a Commercially-Available Software-Defined Radio
Purpose: Conventional commercial MR spectrometers are often limited in configurability, portability, scalability and cost. This has led several researchers to build lower-cost, smaller and more customizable architectures in-house [1-6]. One such approach is a software-defined radio (SDR) architecture [7], comprising high-speed A/D and D/A converters, an FPGA to perform high-bandwidth digital mi...
متن کاملComparison of state-of-the-art atlas-based bone segmentation approaches from brain MR images for MR-only radiation planning and PET/MR attenuation correction
Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...
متن کاملEvaluation of a real time MR-guided interactive navigation device: phantom and animal experiments
Introduction Image guidance for percutaneous biopsy, drainage and therapy not only decreases procedural risk by allowing physicians to access locations that cannot be accessed without real-time feedback, they also improve diagnostic yield by precisely targeting focal lesions. Currently, percutaneous image guided punctures rely mainly on ultrasound and computed tomography guidance. Based on the ...
متن کاملA MR Compatible Mechatronic System to Facilitate Magic Angle Experiments in Vivo
When imaging tendons and cartilage in a MRI scanner, an increase in signal intensity is observed when they are oriented at 55 degrees with respect to Bo (the "magic angle"). There is a clear clinical importance for considering this effect as part of the diagnosis of orthopaedic and other injury. Experimental studies of this phenomenon have been made harder by practical difficulties of tissue po...
