Abstract

Embodiments of the invention disclose a system performance analysis method and device. The method comprises the following steps of: recording a moment of obtaining a target to-be-processed object by a data reading node as a reference moment; sending the reference moment to a data processing node and / or a data storage node except the data reading node; recording a target statistic time period determined by the data processing node and / or the data storage node through referring to the reference moment according to a statistic rule corresponding to a performance statistic index; and calculating a performance statistic index according to the target statistic time period. According to the method and device disclosed by the invention, the system performance analysis speed and correctness are improved.

Description

technical field [0001] Embodiments of the present invention relate to computer technology, and in particular to a system performance analysis method and device. Background technique [0002] The whole CT (Computed Tomography, computerized tomography) system consists of three subsystems: data acquisition, process control and image reconstruction. Among them, the data acquisition subsystem controls the rotation of the frame and the detector collects the rays passing through the object in different directions. The data collected last time by the detector at a certain angle is called a view (View) data, and the collection of all views emitted at one time is called raw data. The image reconstruction subsystem of CT includes five parts: data reading, pre-processing, image reconstruction, post-processing and image storage. The data reading part reads the raw data from the process control subsystem or reads the raw data from the disk. The pre-processing part performs artifact rem...
