Virtual Dye Angiography: Flow Visualization for MRI-guided Interventions
Ashvin K George,Anthony Z. Faranesh,Kanishka Ratnayaka,Kanishka Ratnayaka,J. Andrew Derbyshire,Robert J. Lederman,Michael S. Hansen +6 more
TL;DR: A novel flow visualization method called virtual dye angiography is presented that enables visualization of blood flow analogous to selective catheter Angiography and allows for easy and seamless integration into a real‐time, interactive imaging system with minimal overhead.
Journal ArticleDOI
Efficient implementation of hardware-optimized gradient sequences for real-time imaging.
J. Andrew Derbyshire,Daniel A. Herzka,Daniel A. Herzka,Elliot R. McVeigh,Elliot R. McVeigh,Robert J. Lederman +5 more
TL;DR: This work improves the performance of interactive real‐time imaging with balanced steady‐state free precession by employing hardware‐optimized gradient pulses, together with a novel phase‐encoding strategy that simplifies the design and implementation of the optimized gradient waveforms.

Interventional-Cardiovascular MR: Role of the Interventional MR Technologist
Jonathan R. Mazal,Toby Rogers,William H. Schenke,Anthony Z. Faranesh,Michael S. Hansen,Kendall O'Brien,Kanishka Ratnayaka,Robert J. Lederman +7 more
TL;DR: Interventional-cardiovascular magnetic resonance is a promising clinical tool for adults and children who need a comprehensive hemodynamic catheterization of the heart and it is helpful to understand the unique iCMR preprocedural preparation, procedural and imaging workflows, and management of emergencies.

Mri scanner bore coverings
Robert S. Balaban,Robert J. Lederman,Michael S. Hansen,Anthony Z. Faranesh,Kanishka Ratnayaka +4 more
TL;DR: In this paper, a bore covering for sealing an MRI scanner bore to create a controlled environment within the scanner bore is described. And a system and kit including one or more bore coverings, and a method of using the bore covering to create an incubator-like environment to allow for improved preparation, control, and imaging of infants are described.
