Activation method of PET-CT equipment

Abstract

The invention relates to a PET-CT equipment activation method, and the method comprises the steps that PET-CT control equipment obtains an information code of the PET-CT control equipment, and enables the PET-CT control equipment to transmit the information code to a remote authority control device, so as to achieve the authority distribution and obtain an activation code corresponding to the PET-CT control equipment; and the PET-CT control device receives the activation code, obtains activation information according to the activation code, and activates the PET-CT control device and the PET-CT acquisition device based on the activation information. According to the method, the defects that in the prior art, a PET-CT system is high in activation cost, unsafe in activation mode and prone to leakage are overcome.

Description

technical field [0001] The invention relates to medical equipment technology, in particular to an activation method of PET-CT equipment. Background technique [0002] PET (Positron Emission Tomography) stands for Positron Emitter Tomography. It uses nuclides that can emit positrons to label compounds that can participate in blood flow or metabolic processes in human tissues, and obtain images of cross-sectional, coronal and sagittal sections of the human body. . CT (Computed Tomography) is an electronic computer tomography scan. It uses X-ray beams to scan the human body together with a highly sensitive detector to obtain images of the cross-section, coronal section and sagittal section of the human body. [0003] PET-CT is a fusion of medical images generated by PET and CT through the combination of the two technologies for the diagnosis of clinical physiology and pathology. [0004] The PET-CT machine includes two parts: software system and hardware equipment. The softwa...

Problems solved by technology

[0005] 1. Customers can use all the functions at will when using the software, some advanced functions and scientific research functions cannot effectively control the use rights

[0006] 2. Customers or technical engineers in other PET-CT related fields can replace the hardware accessories of any part of the equipment without the knowledge of the manufacturer, resulting in unstable operation of the equipment, increased failure rate, and manufacturers will bear greater economic losses

[0007] Based on the above usage scenarios, the general manufacturer will activate the software after the complete PET-CT machine is installed at the customer's site. When the software is activated, a USB hardware dongle will be inserted into the computer where the software is running, and the activation related information It will be stored in this hardware encryption lock. This method controls the permissions of each function of the software. For example, the activated function can only be used within the validity period, and the unactivated function and expired function cannot be used. If someone replaces the device accessories without permission, The software will automatically detect the abnormal behavior and prompt the user, and some important functions of the software such as the scanning function will not be available. Although this method can solve the above security problems, the cost of use is high, and each hardware dongle has a purchase cost. And it belongs to a third-party company's product, which is difficult to maintain and expand, and the activation steps are complicated and cumbersome to operate, which cannot meet the expectations of easy-to-use and low-cost use

The second method is to store the activation information in the form of activation code. Although this method reduces the cost of using the dongle, due to the large amount of stored information, especially the too much data of hardware device accessories, it is impossible to store the activation code mapped to a fixed length. In the code, it will cause the hardware accessories to be replaced without permission, the system security will be greatly reduced, and the manufacturer will suffer a large economic loss.

[0008] Therefore, how to solve the problem of the activation authority of each functional module of the PET-CT software system and the possible replacement of equipment accessories has become an urgent problem to be solved at present.
