Appl. No.:

09/200170

Inventors:

Jeffrey S. Hastings - Los Altos CA
Jonathan Bernard - Santa Clara CA
David A. Rock - Saline MI

Assignee:

Acuson Corporation - Mountain View CA

International Classification:

G06K 900

US Classification:

382128

Abstract:

The preferred embodiments include a method and system for simultaneously displaying diagnostic medical ultrasound image clips on one or more monitors without degradation in display frame rate. In one preferred embodiment, compressed ultrasound image frames are sent to a video display system for decompression. Because compressed image frames are sent, there is no degradation in frame rate caused by the bandwidth limitations of the CPU/video display system bus. Further, because the video display system decompress the compressed image frames faster than decompression software executed by a CPU, there is no degradation in frame rate caused by power limitations of the CPU. The video display system can also be used to control the frame rate, luminance, and size of individual ultrasound image clips. The preferred video display system described herein finds particular utility in ultrasound examinations performed in cardiac, radiological, obstetrical, and neo-natal ultrasound examinations.

International Classification:

US Classification:

600437

Abstract:

A method and system for reducing speckle for two and three-dimensional images is disclosed. For two-dimensional imaging, a one and a half or a two-dimensional transducer is used to obtain sequential, parallel or related frames of elevation spaced data. The frames are compounded to derive a two-dimensional image. For three-dimensional imaging, various pluralities of two-dimensional frames of data spaced in elevation are compounded into one plurality of spaced two-dimensional frames of data. The frames of data are then used to derive a three dimensional set of data, such as by interpolation. Alternatively, the various pluralities are used to derive a three-dimensional set of data. An anisotropic filter is applied to the set of data. The anisotropic filter filters at least along the elevation dimension. In either situation, various displays may be generated from the final three-dimensional set of data.

Abstract:

A medical image storage system is provided that integrates a clinical information system with a medical image management system. Such an integrated system can be used in a method that uses clinical information associated with a medical image to determine when and where the medical image should be stored. Because the probability of a medical image being accessed is generally governed by the diagnostic significance of the image, this integrated system provides more efficient storage of medical images as compared to conventional systems that operate independently of diagnostic information.

Abstract:

A method is disclosed for forming an array of focusing elements for use in a lithography system. The method involves varying an exposure characteristic over an area to create a focusing element that varies in thickness in certain embodiments. In further embodiments, the method includes the steps of providing a first pattern via lithography in a substrate, depositing a conductive absorber material on the substrate, applying an electrical potential to at least a first portion of the conductive absorber material, leaving a second portion of the conductive material without the electrical potential, and etching the second portion of the conductive material to provide a first pattern on the substrate that is aligned with the first portion of the conductive absorber material.

International Classification:

US Classification:

82112, 82118

Abstract:

A dynamic alignment monitoring system allows an operator to monitor the misalignment of an on-vehicle disk brake lathe with respect to a vehicle axis about which the disk to be machined rotates, and can allow the operator to discontinue further alignment when appropriate in order to speed the overall time of the alignment process. The system processes signals from an angular rate sensor and a tachometer, using a scaling routine to derive a LRO value corresponding to the LRO of the disk which would result from machining in the current alignment condition. A representation of the derived LRO value is displayed to the operator. An operator override can allow the operator to discontinue further alignment adjustments when an acceptable alignment condition is indicated. The system can aid the operator by also presenting a representation of an acceptable LRO value for the particular vehicle being serviced.

Abstract:

A reporting system, employing a microprocessor, tracks the operation of an on-vehicle brake lathe and provides records of the resurfacing operations performed by the lathe. Identification of the vehicle and wheel position of a brake disk to be resurfaced are inputted using an operator interface, and stored in a temporary memory. When tool bits of the lathe are positioned to set a depth of cut, a thickness monitor indicates the resulting thickness for the brake disk, which is compared to a minimum thickness specification for the inputted vehicle and wheel position to determine whether the disk can be resurfaced to meet the specification. If so, a cutting operation evaluator monitors a continuity checker that is responsive to contact of the tool bits and the disk to determine when the resurfacing operation is complete, at which time the collected data can be reported.

International Classification:

G06F011/08

US Classification:

714/004000

Abstract:

A consumer electronic device, such as a digital video recorder (DVR), has a media storage storing program code modules and content and a network interface for interfacing with one or more remote servers. Content is stored in a content area, modules for monitoring and controlling the consumer electronic device are stored in a system area, and recovery modules are stored in an error recovery area. The monitoring modules activate the recovery modules in response to the detection of an error. The recovery modules diagnose the error and attempt one or more solutions. One solution attempted by the recovery modules is to activate a network recovery module that downloads and installs new program modules for controlling the consumer electronic device from a remote server.
