摘要:
A method for implementing a speckle reduction filter are described. The method includes receiving a processed data stream from a processor, dividing the processed data stream into data subsets, simultaneously filtering the data subsets by using a speckle reduction filter to produce filtered data subsets, and producing an image data stream based on the filtered data subsets.

Provided herein is a recombinant non-human mammal having an immune system including human immune cells and having a liver including human liver cells, and methods for producing the same. Also provided are methods of screening a compound for activity in treating hepatitis, comprising: administering a test compound to a recombinant non-human mammal as described herein; and then detecting the presence or absence of said activity in said mammal (e.g., by biochemical assay), said presence of said activity in said mammal indicating that said compound has activity in treating hepatitis. Methods of making fusion cells useful for the production of human monoclonal antibodies are also provided.

An apparatus for tracking movement of a foreign object within a subject has an X-ray fluoroscopic system with an X-ray detector and an ultrasound system that has a probe with a position sensor. A display is configured to display a static X-ray image acquired by the X-ray fluoroscopic system and a real-time ultrasound image acquired by the ultrasound system. The X-ray image and the ultrasound image each display at least a portion of the foreign object and at least a portion of surrounding area. A tracking module is configured to track movement of the foreign object within the ultrasound image and the display is further configured to display an indication of the movement of the foreign object on the X-ray image

The present invention provides a novel training bag means which can be positioned during use to provide consistent resistance over its entire surface impact area to impact from blows from punching and kicking and the like.
摘要:
The present invention relates to a system and methods for identifying differential peptide expression in one or more peptide populations. Each population is labeled with a discernable label and provides a mechanism to resolve mixed peptide populations using mass spectroscopy-based techniques. Spectra produced by the peptide sample are used to interrogate a spectral database in which peptide sequences of known spectra are stored. In addition to providing sequence information, the methods presented herein may be used to determine qualitative and quantitative measurements of peptide expression. These measurements may further be used to determine proteomic differences and novel peptide expression.

Certain embodiments of the present invention provide a method and system for remote operation of an imaging system. The method includes moving a trackball in a handheld trackball device, transmitting a command based on movement of the trackball to an imaging system, and adjusting a setting or function of the imaging system based on the command. The handheld trackball device includes a trackball for controlling an imaging system based on motion of the trackball, a transmitter for transmitting a command to the imaging system based on motion of the trackball, and a housing for holding the trackball and the transmitter. The device may also include one or more buttons for controlling one or more imaging system functions. The trackball device may work with a voice command, a foot switch, and/or a remote keypad to control the imaging system. The trackball device may also be integrated with an instrument.
摘要:
A system and method for range dependent weighting in ultrasound imaging. The system includes a transducer array, a data acquisition system, and an imaging processor. The transducer array receives a first ultrasound beam having a first focal depth. The data acquisition system receives a first ultrasound imaging signal from the array. The first signal includes first image data based on at least the first ultrasound beam. The imaging processor combines a first data contribution from the first image data with at least second image data from a second ultrasound imaging signal to create a spatially compounded image. The first data contribution is based on at least the focal depth of the first beam.
摘要:
One or more embodiments of the present invention relates to a method and system for simultaneously generating spatially compounded and non-compounded images. In one embodiment, the present invention relates to a method for generating images using an ultrasound apparatus. This method comprises storing at least one frame and generating at least one image output from the at least one frame. The method further comprises displaying at least the generated image output.

摘要:
A method for acquiring images simultaneously is described. The method includes simultaneously acquiring a first image with a second image, where the first image includes at least one of a spatially compounded image and a spatially non-compounded image, and the second image includes one of an M mode image and a Doppler image.
