Aug 17, 2000

Appl. No.:

09/640455

Inventors:

Floyd Wolff - Boca Raton FL 33496

International Classification:

B65D 3700

US Classification:

222211, 2224641, 222564, 222547, 222556, 220259, 220837, 215235

Abstract:

A cap for use in dispensing viscous liquids from containers without the accompaniment of lower viscosity liquid present in the container. The cap has a top portion with an outside surface and an inside surface and an elongated conduit formed at a pre-determined angle. The elongated conduit has an outlet and an inlet. The outlet is situated either eccentrically or concentrically on the outside surface of the top portion such that at least one point on the circumference of the top portion is greater than 10 millimeters from the edge of the inlet.

International Classification:

A61B 505

US Classification:

600411, 600420, 600422

Abstract:

The apparatus and method alters the intravenous delivery of pharmaceuticals to enhance imaging of the vasculature of an animal. The apparatus includes a pressure-inducing component that is sized to attach circumferentially to an extremity of an animal thereby impeding arterial blood flow causing said pharmaceuticals to remain at selected levels within the vasculature.

Abstract:

A method and apparatus is disclosed for MR perfusion acquisition using a notched RF saturation pulse. In acquiring such MR data, a volume of slice locations is selected in which MR data is to be acquired. Each given slice is prepared with a notched RF saturation pulse which has a stop-band between a pair of pass-bands. The stop-band is designed to not affect the spins in the next slice in which MR data is to be acquired thereby effectively increasing the TI and increasing SNR and contrast simultaneously. Since the notched saturation pulse saturates all the spins outside of the notched stop-band, the blood in the ventricular chamber is effectively saturated so that the resulting perfusion images have blood pool suppression. Additionally, the use of a 90Â presaturation RF pulse provides a high level of immunity to the effects of arrhythmias or other variations in the patients heart rate. In order to keep the stop-band, or the notch, as wide as possible to overlap the boundaries of each slice location, it is preferable to interleave the acquisition of slice locations.

International Classification:

A61B005/05

US Classification:

600410000

Abstract:

A method of generating a magnetic resonance image is provided, comprising subjecting a subject to a magnetic field. The subject comprised of a first tissue a second tissue and a third tissue. The method generates a first pulse sequence at a first TI time and generates a first image after the first pulse sequence. The first image has a first image first tissue magnitude, a first image second tissue magnitude, and a first image third tissue magnitude. The method then generates a second pulse sequence at a second TI time and generates a second image after the second pulse sequence. The second image has a second image first tissue magnitude, a second image second tissue magnitude, and a second image third tissue magnitude. Finally, the method generates a resultant image by combining the first image and the second image. The first image first tissue magnitude and the second image first tissue magnitude combine to form a positive resultant first tissue magnitude. The first image third tissue magnitude and the second image third tissue magnitude combine to form a negative resultant image third tissue magnitude.

International Classification:

A61B 5/00

US Classification:

600561

Abstract:

Embodiments presented herein provide apparatus and methods for imaging-assisted determination of pressure gradient of blood flow across a valve orifice in a cardiovascular circuit without the use of velocity data measured at the valve orifice. An embodiment of the methods comprise creating an image of a valve orifice, creating a planimeter slice from the image of the valve orifice including a trace of the perimeter of the valve orifice, determining the valve orifice area by determining the area contained within the trace, determining the instantaneous flow rate through the valve orifice based on bulk flow data away from the valve, and determining the instantaneous pressure gradient across the valve orifice from the valve orifice area and the instantaneous flow rate.

Abstract:

A physiologic transmitter manages multiple communications between physiologic data acquisition devices attached to the patient and a receiver attached to an MRI or CT scanner. The transmitter's processor is able to generate waveform data and trigger data based upon the acquired physiologic data and transmit the data to a physiologic receiver attached to the host scanner. The receiver then is able to deliver a trigger signal to the host scanner for imaging the patient during a selected time frame based upon cardiac and/or respiratory cycles of the patient.
