Method and system for authorizing flat panel detector as required

Abstract

The invention provides a method and a system for authorizing a flat panel detector as required. The flat panel detector comprises at least an FPGA (field-programmable gate array) chip with a unique identification code, and different FPGA chips have different identification codes. The method for authorizing the flat panel detector as required at least includes defining an authorization code according to a required authorization mode; generating an authorization document based on the identification code and the authorization code; detecting the authorization document when the flat panel detector is powered on and runs every time or an exposure process is completed every time so as to confirm relevant authorization information of the required authorization mode; executing the required authorization mode according to the confirmed relevant authorization information. The method and the system for authorizing the flat panel detector as required has the advantages that the flat panel detector can be subjected to authorizing protection, so that various sales patterns and strategies can be achieved flexibly; an embedded program of the flat panel detector can be effectively protected from being cloned and embezzled.

Description

Technical field [0001] The present invention relates to the technical field of digital X-ray flat panel detectors, in particular to a method and system for flat panel detectors on-demand authorization. Background technique [0002] Digital Radiography (DR) is a new X-ray photography technology developed in the 1990s. With its significant advantages such as faster imaging speed, more convenient operation, and higher imaging resolution, it has become The leading direction of digital X-ray photography technology has been recognized by clinical institutions and imaging experts all over the world. The core of the DR technology is a flat panel detector. The flat panel detector is a sophisticated and valuable device that plays a decisive role in the image quality. [0003] The flat panel detector is the X-ray receiving device in the DR system. In the DR system, the high-voltage generator and the tube control the output of X-rays. X-rays pass through the object and are attenuated. After ...
