摘要： A variable-frequency bus adapter, a variable-frequency bus adapting method and a variable-frequency bus adapting system are provided. The method includes: generating a bus blocking indication according to a dynamic frequency scaling (DFS) request signal sent by a bus side; blocking a current bus transfer according to the bus blocking indication; and feeding back a DFS response signal to the bus side after blocking the current bus transfer, where the DFS response signal is adapted to enable the bus side to perform a DFS operation. In the method, the bus transfer is temporarily blocked during the DFS, so that undesired influence on peripheral components caused by unstable bus block during the bus DFS is reduced without increasing the number of clock domains of the system or modifying the peripheral components, thus reducing the complexity of the implementation of the system, and improving the applicability of dynamic voltage frequency scaling (DVFS).

摘要： The analysis image generating unit generates section images from volume analysis data that is collected by sending an ultrasound wave down to a region under the ribs. The right/left identifying unit identifies the right or left breast from cyclic motion components in the section images. The extending direction detecting unit analyzes plane-A images or plane-B images generated from the same volume analysis data, or a plane-C thickness-added MIP image, and detects the rib extending direction. The extending direction detecting unit also determines the position of the ultrasound probe based on the relative displacement of the extending direction. The body mark generating unit generates a body mark from the analysis results obtained by the right/left identifying unit and the extending direction detecting unit. The image synthesizing unit integrates the display image generated by the display image generating unit and the body mark, and displays it on the monitor.
