Embodiment 1
[0044] This embodiment provides a CT scanning system, which is used in the security inspection field, the medical field and other fields.
[0045] refer to figure 1 and figure 2 , the CT scanning system provided in this embodiment includes a first ray generating device 10 , a second ray generating device 20 and a common detection device 30 .
[0046] The first ray generating device 10 is used for generating a first ray beam, and the first ray beam has a first energy;
[0047] The second ray generating device 20 is configured to generate a second ray beam, the second ray beam has a second energy, and the second energy is greater than the first energy;
[0048] The common detection device 30 is arranged in the ray beam exit direction of the first ray generator 10 and the second ray generator 20, and is used for receiving the first ray beam and the second ray beam, and generating the first projection data of the first ray beam and second projection data of the second beam of ...
Embodiment 2
[0075] This embodiment provides a CT scan data processing method, which is applied to the CT scan system provided in the first embodiment. For the specific content of the CT scanning system, reference may be made to the corresponding description in Embodiment 1, which is not repeated here.
[0076] refer to Figure 4 , the CT scan data processing method provided by this embodiment comprises the following steps:
[0077] Step S100 , determining the relative position difference between the first ray generating device 10 and the second ray generating device 20 in the longitudinal direction of the scanning area 40 .
[0078] Step S200, acquiring first projection data and second projection data.
[0079] Step S300: Align the first projection data and the second projection data based on the relative position difference to obtain equivalent projection data.
[0080] In step S400, substance detection is performed based on the equivalent projection data.
[0081] Since the first ra...
Embodiment 3
[0094] This embodiment provides an electronic device, such as Image 6 As shown, the electronic device includes a memory 100 and a processor 200 . Wherein, the memory 100 and the processor 200 are connected in communication with each other, and may be connected by a bus or in other ways, Image 6 Take the connection through the bus as an example.
[0095] The processor 200 may be a central processing unit (Central Processing Unit, CPU). The processor 200 may also be other general-purpose processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuit (Application Specific Integrated Circuit, ASIC), Field-Programmable Gate Array (Field-Programmable Gate Array, FPGA) or Other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components and other chips, or a combination of the above types of chips.
[0096] As a non-transitory computer-readable storage medium, the memory 100 can be used to st...
