The system of one embodiment for ultrasound image computation of cardiac events comprises an ultrasound device, an electrocardiogram device, and a processor comprising a first module to receive and process ultrasound data, a second module to receive electrocardiogram signals, a third module to relate ultrasound signal events to electrocardiogram signals, and a fourth module to determine a relative timing between ultrasound signal events.
Abstract:
A method for measuring motion from biological imaging data including collecting non-carrier data images; patterning the non-carrier data images with synthetic carrier properties; and processing the patterned non-carrier data images with a carrier based motion tracking technique to generate images representing motion measurements. The method preferably converts images lacking a carrier signal to ones with a synthetic carrier signal such that highly accurate and robust speckle tracking can be achieved.
Abstract:
A transparent assembly locatable in a building surface having a rebate is described. The assembly has a transparent panel and one or more high tensile strength flexible material reinforcement pieces extending laterally from the panel to provide non-rigid attachment of the assembly to a subframe and/or wall, wherein the attachment allows movement of the assembly within the rebate. By direct but non-rigid attachment of the transparent assembly, generally a window, to the subframe and/or wall, any weakness in the impact-resistance of the assembly because of weakness and/or damage to the frame is avoided. The non-rigid nature of the attachment allows it to absorb much of the blast loading. This allows a large load on the transparent assembly to be supported by the subframe and/or wall. The present invention also provides a number of ballistic-resistant and blast-resistant assemblies providing protection against much higher levels of protection from high velocity weapons and explosives.
Abstract:
A method for acquiring and processing 3D ultrasound data including acquiring partial 3D ultrasound data. The partial 3D ultrasound data is composed of partial 3D ultrasound data frames that are collected by collecting an ultrasound target plane and collecting at least one ultrasound offset plane. The method additionally includes processing the partial 3D ultrasound data.
Abstract:
One embodiment is a method for real-time window processing and window definition that includes measuring a defining signal and an instantaneous tissue state signal, dynamically determining a time window from the defining signal, and processing instantaneous tissue state signal captured in the time window. Another embodiment is a system for processing a real-time ultrasound signal within a time window that includes a physiological signal monitor that measures a physiological signal, an ultrasound acquisition device that acquires an ultrasound signal, a window identifier that uses the physiological signal to identify boundary markers of the output of the physiological signal monitor that define a time window, and an ultrasound processor that processes the ultrasound signal within a time window and outputs a time window processed ultrasound signal. The embodiments have applications in the field of ultrasound tissue tracking and numerous other tissue monitoring fields.

Abstract:
A rotary cutting die which is mountable on a metal cylinder. The rotary cutting die includes a rotary die plate having a concave, inner surface which is magnetically attractable and magnetically mountable on a metal cylinder. A cutting blade is mounted on a concave, outer surface of the die plate. Connectors may be engaged with the cutting blade and the die plate. A plurality of magnetic elements, such as neodymium magnets, are in the rotary die plate. The magnetic elements make the inner surface of they die plate magnetically attractable to the metal cylinder, thereby providing that the rotary cutting die is mountable on the metal cylinder without having to use screws, clamps or other mechanical holding devices. To prevent creep of the cutting die during operation, a magnetic member, such as a rubber magnet, may be magnetically mounted on the die cylinder, against the die plate.
