Method and system for expanding maximum storage capacity of ultrasound image data

Abstract

The invention provides a method and a system for expanding maximum ultrasonic image data memory capacity. The method comprises the following steps: 1, setting one time data collection cycle time; 2, starting counting from the collection cycle time, and emptying buffering data in a hard disc; 3, collecting real-time image data, and carrying out processing on the collected image data; 4, writing the processed image data into an internal memory, at the same time, enabling partial data which are written into the internal memory to be buffered into a buffer area of the hard disc in parallel; and 5, after one collection cycle is finished, preparing to finish collection of a next cycle. Through the method for expanding the maximum ultrasonic image data memory capacity, buffering capacity when images are stored is enhanced, scanning time of the system is prolonged, an integral use ratio of hardware of a machine is improved, meanwhile, the one time data collection cycle time can be flexibly set in an application, buffering efficiency is improved and strategies of capacity expanding are explicit.

Description

technical field [0001] The invention relates to the field of ultrasonic diagnosis, in particular to a method and system for expanding the maximum storage capacity of ultrasonic image data. Background technique [0002] In ultrasonography, the real-time image data collected from the hardware will be stored after preprocessing (or intermediate process processing) for use in subsequent processing algorithms and display algorithms. However, the acquisition of real-time images has higher requirements on speed. If the speed of subsequent processing and display is lower than the speed of front-end acquisition, users will feel a more obvious delay, and even the image will stop. Data access speed is one of the important links. [0003] The current ultrasound image data storage technology mainly pre-allocates the available memory according to the memory capacity, and the data is stored in the memory during the whole process to speed up the access. When the memory is about to run out...

Problems solved by technology

When the memory is about to run out, some operating systems will automatically dump the memory data to the hard disk buffer. If the ultrasound software cannot control this process, then in some processing procedures, when accessing a piece of memory that is being dumped, due to the operation System reasons may cause timeout problems, affecting the processing time of the algorithm and the fluency of the display
