摘要:
In one embodiment of the invention, there is an ultrasound processing system that communicates images over a single asynchronous serial channel according to a scheme that does not require an isochronous serial channel and that switches among ultrasound imaging modes robustly. For example, the system is configured to packetize ultrasound image data of at least one ultrasound imaging mode into a stream of data frames and to convey the stream of data frames via the asynchronous channel. Each data frame includes indication of the ultrasound imaging mode and includes ultrasound-imaging-mode-specific imaging parameters. Other embodiments exist.

An ultrasonic image scanning system for scanning an organic object includes a beam former that provides a phase velocity adjustment function for producing an ultrasonic image with a programmable phase velocity. The ultrasonic image scanning system further includes a beam profile analysis function for calculating an optimal phase velocity with a user controller to adjust the phase velocity until a scan image of best image quality is achieved. Alternately, the system may provide an automatic phase velocity-scanning controller for automatically scanning through a range of phase velocities and selecting a best phase velocity generating a scanning image of a best quality. The system further includes a region of interest (ROI) controller for a user to select a region for scanning with a specific focal area for optimizing the phase velocity. The system may further provide a maximum gradient analyzer for selecting an image of a best quality in optimizing the phase velocity. A digital controller may also provide a real time programmable control by applying different control algorithms with combination of phase velocity and attenuation adjustment. A hardness computational processor is implemented to determine a tissue hardness using the phase velocity and in combination with the attenuation parameter.

The present invention relates to a stainless steel thermal insulation drinking beverage container and a manufacturing method thereof, particularly with regard to a stainless steel thermal insulation drinking beverage container which can reduce unpleasant odor therein and is convenient to clean up. The container is made through manufacturing steps of preparing and providing a bottle body, vacuuming, surface treatment, spray coating, baking and drying, and high temperature sintering, and so on. A ceramic layer is formed on an inner wall face of the stainless steel bottle body with a vacuum mezzanine. Accordingly, the ceramic layer is used for blocking direct contact between drinking beverages and the stainless steel bottle body in order to reduce occurrence of unpleasant odor in drinking beverages and to enhance convenience of cleaning up.

A positioning structure of an inner and an outer insulation sleeve member for an antenna, the sleeve members are an outer insulation sleeve and an inner insulation connecting rod insertion connecting with each other to form the main housing of the antenna, wherein, the inner connecting rod has thereon an upper and a lower protruding rib in corresponding respectively to an upper and a lower inner annular recess provided on the outer sleeve. The lower inner annular recess and the lower protruding rib had better be both in a truncated conical shape flared downwardly to form an abutting shoulder to help guiding for insertion connecting and to prevent slipping off of them by an axial pulling force. The inner connecting rod has thereon notches corresponding in position to the pending tongs on the top of the outer sleeve; and the inner and the outer sleeve members can synchronically be positioned in the peripheral direction.

The present invention discloses a magnetic nanodrug for treating thrombosis, which comprises a core formed of magnetic nanoparticles, a shell enveloping the core and made of carboxyl-functionalized polyaniline, and a thrombosis-treatment drug covalently bonded to the shell. The magnetic nanodrug of the present invention is non-toxic to vascular endothelial cells, has superior stability, features superparamagnetism, and can be uniformly dissolved in water. Therefore, the magnetic nanodrug for treating thrombosis can be guided by an external magnetic field to concentrate on a specified region and increase the effect of thrombosis treatment.
