6629469, Oct 7, 2003

Filed:

Jun 5, 2001

Appl. No.:

09/874582

Inventors:

Ronald J. Jaszczak - Chapel Hill NC
Paul Douglas Kirven - Durham NC
Timothy Warren Perry - Hillsborough NC

Assignee:

Data Spectrum Corporation - Hillsborough NC

International Classification:

G01M 1900

US Classification:

738664

Abstract:

A cardiac phantom is provided for simulating a dynamic cardiac ventricle. The phantom comprises two concentrically-disposed, fluid-tight, flexible membranes defining a closed space between the walls of the membranes. A pump is operatively connected to the inner membrane for reciprocally delivering a volume of fluid to the inner membrane to inflate and deflate both membranes in simulating systole and diastole of a heart. A medium is disposed within the closed space defined between the walls of the membranes for maintaining a uniform distance between the walls of the membranes during inflation and deflation. The phantom is provided for evaluation of medical imaging systems. A method, computer system and a computer-readable medium are also provided for controlling the phantom.

Abstract:

A curable composition including a reactive monomer or oligomer with acrylate functionality, an amine, and an alkyl peroxide. The alkyl peroxide is free or substantially free of phenyl rings. The alkyl peroxide can be dilauroyl peroxide (DLP). The curable composition can also include 3,5-diethyl-1,2-dihyrdro-1-phenyl-2-propylpyridine (PDHP). The curable composition can be provided as a two-part adhesive composition, including an A-side with DLP and an acrylic monomer, and a B-side with PDHP.
