Embodiment Construction

[0012] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways than those described here, so the present invention is not limited by the specific embodiments disclosed below.

[0014] The present invention provides a fast fault diagnosis process, divides the system into DCB-DIF link layer and DIF-DBB link layer, and performs fault detection on these two link layers respectively, which improves the speed and accuracy of fault diagnosis .

[0015] Such as figure 2 As shown, the detector fault detection method of the present invention comprises the following steps:

[0016] Step S1: The DCB sends a data collecti...

Abstract

The present invention provides a method and device for carrying out rapid fault diagnosis of a detector. The method comprises the steps that: a data control board sends a data collection command to an associated data interface and the detector in real time when a system is running; the data from the data interface and the detector are processed to determine the existence of a fault; if the fault is determined, the data control board carries out response information collection; and response information is sent to a master control unit, and the master control unit carries out fault positioning.

Description

technical field [0001] The invention mainly relates to a detector in a CT system, in particular to a fast fault diagnosis method and device for the detector. Background technique [0002] CT (computedtomography, computerized tomography) equipment is a fully functional disease detection instrument. X-ray CT equipment mainly includes the following components: X-ray tube, X-ray detector, scanning control system, image acquisition and processing system. In medical applications, by scanning a layer of a certain thickness of the human body, the detector receives the X-rays passing through the layer and converts them into energy intensity signals, and the data acquisition and processing system collects the energy intensity signals and combines them with A certain algorithm reconstructs the original image. Using CT equipment, doctors can clearly observe the conditions of body tissues that are difficult to show on ordinary X-ray films, such as cerebral hemorrhage and various small ...
