US Classification:

705 3

Abstract:

A method and system for automated management of tissue information, where the tissue information, which may include intake tissue information upon receiving a tissue, inventory information, preparation information, and usage information of the tissue is input to a database via a user terminal, where the user terminal prompts a user to input any required tissue information. A patient record, including the tissue information, may be created in the database. Post-operative patient reaction information may be added subsequently to the patient record. The tissue information and the patient record are searchable and updatable using one or more user terminals at various times.

International Classification:

G06F 17/30

US Classification:

707102, 707E17001

Abstract:

A method and system for implant record intake using a unique implant ID include inputting to a database a lot number of a tissue, corresponding to a donor of the tissue. A unique serial number is assigned to the tissue and the unique implant ID is created using the lot number and the serial number. A barcode encoded with the unique implant ID may be generated and affixed to a container of the tissue. Further, information about the tissue, input at one or a plurality of user terminals, is associated with the unique implant ID in the database to create a searchable electronic record.

International Classification:

G01P 15/00

US Classification:

702141

Abstract:

An accelerometer system can include a sensor element comprising first and second proofmasses, the first proofmass accelerating in a first direction and the second proofmass accelerating in a second direction opposite the first direction in response to an external acceleration. A force rebalance controller applies control signals to at least one control element to provide a first force to accelerate the first proofmass toward a first null position and to at least one control element to provide a second force to accelerate the second proofmass toward a second null position. The force rebalance controller can also generate opposite polarity first and second output signals associated with respective displacements of the first and second proofmasses relative to the respective first and second null positions. An acceleration component calculates the external acceleration based on the first and second output signals.

Inventors:

Ming Li - Seattle WA

Assignee:

Siemens Medical Systems, Inc. - Iselin NJ

International Classification:

A61B 800

US Classification:

12866108

Abstract:

A method for measuring the interframe movement of pixels in a second ultrasoud image frame with respect to the pixels in a first ultrasoud image frame. The movement information may be displayed to provide enhanced information about the underlying physiology or to provide a temporally compounded image having reduced noise. In the preferred embodiment of the present invention, the pixels in that actually change between frames are identified. The first frame is divided into blocks and an estimated velocity computed for each block having a sufficient number of pixels that actually moved between the first and second frames. After all of the velocity estimates have been computed, blocks having questionable velocity estimates are identified. Blocks for which the velocity estimate was questionable are then provided with a velocity estimate by interpolating the velocity vectors of the nearby blocks having valid velocity estimates. The preferred method for estimating the velocity utilizes a modified optical flow computation that is more stable than prior art optical flow models.

International Classification:

A61B 800

US Classification:

12866007

Abstract:

A region of tissue is scanned as a series of 2-D frames. The correlation of substantially homogeneous speckle regions in the frames is determined and is compared with a precalibrated speckle correlation-versus-distance function to give an estimate of the distance between the frames. In some applications, the frames are partitioned into sub-frames, whose correlation values and distances are combined according to predetermined functions to give a distance estimate between the frames as a whole. The reliability of the distance estimates is improved and evaluated in various ways, for example, by comparing combinations of possible distances from end frames via intermediate frames, and by comparing computed frame or sub-frame velocities with a known or estimated transducer velocity. Once the relative distances of the 2-D frames are estimated, a 3-D image is compiled using registration techniques. Image frames need not be parallel.

Assignee:

Siemens Medical Systems, Inc. - Iselin NJ

International Classification:

A61B 800

US Classification:

12866101

Abstract:

An ultrasonic imaging system is provided that effectively corrects for inhomogeneities in the imaged media. The ultrasonic imaging system comprises a transducer array having a plurality of transducer elements each being separately operable to provide an ultrasonic pulse in response to a driving signal and to provide a corresponding echo signal in response to a received echo based on the ultrasonic pulse. A transmitter is coupled to the transducer array and provides the driving signal to each respective one of the transducer elements. The driving signals define a steered beam of the transducer array. A receiver is coupled to the transducer array and receives the echo signal from each respective one of the transducer elements. The receiver includes a beamformer section that produces a single matched and summed signal from the echo signals of the plurality of transducer elements. The beamformer section comprises a plurality of processing modules coupled in a cascading arrangement with separate processing stages.

International Classification:

A61B 800

US Classification:

12866007

Abstract:

An interrogation region of a patient's body is scanned with an ultrasonic probe. At least one input data frame is generated representing the scanned interrogation region as a pattern of image elements, each with a corresponding input intensity value, that are stored in a memory. The input data frame is then displayed as a pattern of displayed intensity values, which the processor calculates as combination of a geometry-independent function of an ambient light input array and a geometry-dependent function of the input intensity values, in which the geometry-dependent function includes a coefficient term that multiplies the input intensity array and that itself is a function of the input intensity values. As part of the coefficient term is a filtered input data array, which results from noise-floor filtering, low-pass filtering, and surface normal vector averaging of the input intensity array. In a preferred embodiment of the invention, the user selects an assumed light source vector, and/or an assumed viewer direction vector, which are the incorporated into the geometry-dependent function used to calculate displayed intensity values.
