Testing method and device of imaging system and imaging system

The invention provides a testing method and device of an imaging system and the imaging system.The method comprises the steps that interface content characteristics of a testing interface of a control end are obtained by executing a pre-created script file, the interface content characteristics are analyzed, and therefore the position of a control to be operated in the testing interface is recognized; triggering an action event of the control to be operated of the current test interface according to the position of the control to be operated so as to enable the test process to enter a next node, automatically shooting the phantom through a projection end, and reconstructing a shot image to obtain a three-dimensional CT image; and comparing the CT image with a pre-collected corresponding first sample image to obtain an image deviation condition, and determining a test result of the imaging system according to the image deviation condition. According to the method and the device, the operation of an operator is
