Background technique

At present, flat-panel detectors are widely used in optical medical diagnosis. X-rays are projected onto flat-panel detectors after passing through the human body. Through real-time image processing, image digital signals are directly obtained, and then transmitted to workstations. The workstations use computers as the main body. The technology collects, processes, transmits and displays digital images on a monitor for medical personnel to observe the images and perform medical diagnosis.

The test of flat panel detector SDK (Software Development Kit, software development kit) has a high degree of dependence on the test environment. In addition to flat panel detectors, it usually requires the cooperation of X-ray generators and software interfaces. Testers operate the software interface to There are two shortcomings in the process of testing the SDK:

1. Insufficient flexibility, insufficient coverage, and inconvenient rapid regression and iteration. The process of the software interface is relatively fixed, and it is not easy to customize the process. If there is no process in the interface, it cannot be tested. Moreover, the way the self-developed software interface uses the SDK may be different from the way the DR customer integrates the SDK. Usually, the implementation of automated testing requires the help of third-party commercial software.

As shown in Figure 2, the automatic testing method of the flat panel detector software of the present embodiment mainly comprises the following steps:

S201: Obtain a test input. The test input includes: a series of test case files written in advance, or a file list of the series of test case files, wherein the test case files belonging to the file list will be executed simultaneously.

Optionally, the series of test case files are written based on xml language. Use the XML language to write the test process. The steps in the process can be calls to the SDK interface, or any custom actions, such as driving peripherals (high-voltage generators for X-ray generators), etc. Furthermore, an interpretation engine can also be designed based on the XML custom process, so as to explain the custom process.

Generally, the working modes of the flat panel detector include: software mode, prep mode, out mode, sync in mode, inner mode, freesync mode, etc. specific:

1) For the test software mode, since the test can be performed without other peripherals, the test case does not need to include the test steps to control the electronic equipment carried by the test tool to collect images, that is, there is no test case in the test case. Need to write the steps to send the trigger signal to the X-ray generator;

2) For the use cases of testing prep mode, out mode, and sync in mode, if you want to collect images, you need to include the steps of controlling the electronic equipment carried by the test tool, so as to control the electronic equipment to detect the flat panel through the X-ray generator The transmitter sends a hardware electrical signal to trigger image acquisition, that is:

The test case of the prep mode includes a step of sending a first instruction to the X-ray generator, so that the X-ray generator sends a level signal for preparing exposure to the flat panel detector for the The flat panel detector returns a ready response signal to the X-ray generator according to the level signal, and collects a picture by itself after a fixed period of time;

The test case of the out mode includes the step of sending a second instruction to the X-ray generator, so that the X-ray generator sends a level signal ready for exposure to the flat panel detector for the The flat panel detector returns a ready response signal to the X-ray generator according to the level signal, and takes pictures after receiving the exposure completion notification sent by the X-ray generator;

In the test case of the sync in mode, the step of sending a third instruction to the X-ray generator is included, so that the X-ray generator sends a level signal for preparing exposure to the flat panel detector, and periodically Notify the flat panel detector that the exposure is complete, thereby triggering the flat panel detector to take pictures periodically.

3) For the test cases of testing inner mode and freesync mode, since the flat panel detector needs to perceive X-rays to upload images, these two modes are different from the previous 1) and 2), and an X-ray generator must be used to trigger the image above. Therefore, in the test case file, it is necessary to define the steps to control the electronic equipment carried by the test tool, so as to control the electronic equipment to send electrical signals to the X-ray generator, and further trigger the above picture of the flat panel detector, that is, in the inner mode, or the test case of the freesync mode includes the step of sending a fourth instruction to the X-ray generator, so that the X-ray generator sends X-rays for the X-ray detection part of the flat panel detector After the X-rays are detected, the pictures are taken. At this time, due to the need for the support of the X-ray generator, the test tool sends instructions to the electronic device through the serial port (or other connection methods), and the electronic device sends a hand switch signal to the X-ray generator to command the high-voltage generator to discharge the wire at high voltage. And trigger the flat panel detector to take pictures.
