Description

Technical Field

[0001] The present invention relates to the field of network communication technology for nuclear medicine imaging equipment, and in particular, to a method for communicating between core components of nuclear medicine equipment such as SPECT, SPECT / CT, and Gamma cameras through a TCP / IP protocol, and testing and correcting data, and in particular, to a lightweight data verification method and system for nuclear medicine imaging equipment. Background Art

[0002] Nuclear medicine imaging equipment such as SPECT / CT and Gamma cameras need to coordinate the operation of multiple core components such as patient supports, racks, and detectors to complete a scanning process. The various components communicate over the network based on the TCP / IP protocol to exchange messages. During the scanning process, when the detector is in close proximity mode, the distance between the detector and the patient needs to be controlled in real time to avoid the dangerous situation of the detector squeezing the patient. Therefore, real-time control of the position of the detector is a safety risk control that must be performed. In actual applications, data is tested based on multiple factors such as patient weight, horizontal position of the patient support, vertical height, and bed deformation. The interference curve is simulated through MATLAB, and then the data within the safety range is obtained, and the data output is saved as an interference safety file.

[0003] In SPECT / CT and Gamma camera equipment, the movement of the detector requires the detector command control subsystem and the detector motion control subsystem to communicate over the TCP / IP network to jointly complete the motion control. However, even if the interference safety judgment is added to the control logic, due to the huge amount of data, it is impossible to verify every data point in the interference safety file in the actual scanning process, and there are still certain safety risks.

[0042] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0043] The embodiment of the present invention provides a lightweight data verification method for nuclear medicine imaging equipment, which is applied to equipment such as SPECT / CT, Gamma camera, etc. Figure 1 As shown, the method specifically includes:

[0044] Step S1: The detector command control subsystem in the nuclear medicine imaging device is separated into GCC (Gantry Controller Control) as the server of the TCP / IP communication protocol, and the detector motion control subsystem is separated into DCC (Detector Controller Control) as the client of the TCP / IP communication protocol; TCP / IP communication is established by specifying the communication IP address and port number; the communication IP address is specified as the local IP address, and the communication port number is set to a port number that does not conflict with other local port numbers.

[0045] Step S2: Refer to Figure 2 As shown, the server GCC reads the interference safety file and stores the data in the buffer. According to the data range in the interference safety file, the initial values ​​of the bed height, horizontal position and gantry angle are set. The following functions are implemented: when the horizontal position and bed height are constant, the gantry angle covers a period range (a period range is 360 degrees, and the step unit is 1 degree), and the horizontal position, bed height position, and gantry angle information are sent to the client according to the motion command format. (The bed height range is V, the bed height step unit is s1, the horizontal position range is H, and the horizontal position step unit is s2). It is worth noting that the bed height range V, bed height step unit s1, horizontal position range H, and horizontal position step unit s2 all need to be determined according to the interference safety file data. For example: at a certain horizontal position h and a certain bed height v (h is included in H, v is included in V), the gantry angle ranges from 0 degrees to 360 degrees, and each gantry angle corresponds to a set of data on the maximum distance the detector can move. The maximum distance that the detector can move in a rack angle cycle covered by such a set of specific horizontal positions and bed heights is an interference safety file, and several interference safety files are composed according to the horizontal range and bed height range.

[0046] Specifically, first determine whether the currently set horizontal position value is greater than or equal to the lowest threshold of the horizontal range in the interference safety file. If not, directly terminate the data transmission. Otherwise, further determine whether the current bed height value is less than or equal to the highest threshold of the bed height range in the interference safety file. If not, use the current horizontal position value plus the horizontal step unit s2 as the current horizontal position. Otherwise, further determine whether the currently set rack angle value is greater than or equal to the highest threshold of the rack angle in the interference safety file. If not, use the current bed height value plus the bed height step unit s1 as the current bed height value. Otherwise, send a message to the client, and the message content includes the current horizontal position, current bed height and current rack angle information.

[0047] Step S3: Refer to Figure 3 As shown in the figure, the client DCC reads the interference safety file data and stores the data in the buffer. At the same time, it receives the message sent by the server in real time, and parses the initial value information of the horizontal position, bed height position and rack angle in the message. According to the current horizontal position and current bed height, it determines which interference safety file data in the buffer is read, and then uses the binary search method to find the maximum movable distance of the detector corresponding to the current rack angle information in the interference safety file in the buffer according to the current rack angle information. By writing the parameter information read after processing each message into the new verification file, all verification files corresponding to the interference safety file are obtained.

[0048] Step S4: Refer to Figure 4 As shown, a data verification execution program is created. By specifying the interference safety file path and the verification file path in step S3, all file name paths under the two paths are read into buffer 1 and buffer 2 respectively, and then each file is traversed from buffer 1 and buffer 2, and each file content in buffer 1 is stored in buffer 3, and each file content in buffer 2 is stored in buffer 4. Compare the data in buffer 3 and buffer 4. If all are correct, "Check Ok" is output on the console. If there is a difference, the file path name and corresponding data content with the difference are output on the console. Thus, data verification is automatically completed.

[0049] Step S5: After the above steps, the GCC server program can send each data in the interference security file to the client DCC. DCC generates verification data corresponding to the original data in each interference security file based on the interference logic judgment of step S3, and the verification program can realize the comparison of all data, thereby completing the full coverage test verification of the interference security data.

[0050] The present invention also provides a lightweight data verification system for nuclear medical imaging equipment, which can be implemented by executing the process steps of the lightweight data verification method for nuclear medical imaging equipment, that is, those skilled in the art can understand the lightweight data verification method for nuclear medical imaging equipment as a preferred implementation of the lightweight data verification system for nuclear medical imaging equipment. The system specifically includes:

[0051] Module M1: The detector command control subsystem in the nuclear medicine imaging equipment is separated into GCC (GantryController Control) as the server of the TCP / IP communication protocol, and the detector motion control subsystem is separated into DCC (Detector Controller Control) as the client of the TCP / IP communication protocol; TCP / IP communication is established by specifying the communication IP address and port number; the communication IP address is specified as the local IP address, and the communication port number is set to a port number that does not conflict with other local port numbers.

[0052] Module M2: The server GCC implements the following functions according to the data range in the interference safety file: When the horizontal position and bed height are constant, the gantry angle covers a cycle range (a cycle range is 360 degrees) (the step unit is 1 degree), and the horizontal position, bed height position, and gantry angle information are sent to the client according to the motion command format. (The bed height range is V, the bed height step unit is s1, the horizontal position range is H, and the horizontal position step unit is s2). It is worth noting that the bed height range V, bed height step unit s1, horizontal position range H, and horizontal position step unit s2 all need to be determined according to the interference safety file data. For example: at a certain horizontal position h and a certain bed height v (h is included in H, v is included in V), the gantry angle ranges from 0 degrees to 360 degrees, and each gantry angle corresponds to a set of data on the maximum distance that the detector can move. In this way, the maximum distance that the detector can move in a gantry angle cycle covered by a set of specific horizontal positions and bed heights is an interference safety file, and several interference safety files are composed according to the horizontal range and bed height range.

[0053] Specifically, first determine whether the currently set horizontal position value is greater than or equal to the lowest threshold of the horizontal range in the interference safety file. If not, directly terminate the data transmission. Otherwise, further determine whether the current bed height value is less than or equal to the highest threshold of the bed height range in the interference safety file. If not, use the current horizontal position value plus the horizontal step unit s2 as the current horizontal position. Otherwise, further determine whether the currently set rack angle value is greater than or equal to the highest threshold of the rack angle in the interference safety file. If not, use the current bed height value plus the bed height step unit s1 as the current bed height value. Otherwise, send a message to the client, and the message content includes the current horizontal position, current bed height and current rack angle information.

[0054] Module M3: The client DCC reads the interference safety file data and stores the data in the buffer. At the same time, it receives the message sent by the server in real time, parses the horizontal position, bed height position and frame angle information in the message, searches for the data in the corresponding interference safety file in the buffer according to the current parameters, and writes the parameter information read after processing each message into the new verification file, thereby obtaining all the verification files corresponding to the interference safety file.

[0055] Module M4: Create a data verification execution program. By specifying the interference safety file path and the verification file path in step S3, all file name paths under the two paths are read into buffer 1 and buffer 2 respectively, and then traverse each file from buffer 1 and buffer 2, and store each file content in buffer 1 into buffer 3, and store each file content in buffer 2 into buffer 4. Compare the data in buffer 3 and buffer 4. If all are correct, output "Check Ok" on the console. If there is a difference, output the file path name and corresponding data content with the difference on the console. Thus, data verification is automatically completed.

[0056] Module M5: After the above steps, the GCC server program can send each data in the interference safety file to the client DCC. DCC generates verification data corresponding to the original data in each interference safety file based on the interference logic judgment of module M3, and the verification program can realize the comparison of all data, thereby completing the full coverage test verification of the interference safety data.

[0057] Next, the present invention will be described in more detail.

[0063] S12: GCC implements the following functions according to the data range in the interference safety file: when the horizontal position, bed height position, and rack angle are certain, it sends a message to the client according to the motion command format.

[0064] S13: DCC reads the interference safety file data and stores the data in the buffer, receives the message sent by the server, and parses the horizontal position, bed height and rack angle information in the message. According to the current horizontal position and current bed height, it determines which interference safety file data in the buffer is read, and then uses the binary search method to find the maximum distance that the detector can move corresponding to the current rack angle information in the corresponding interference safety file in the buffer according to the current rack angle information. By writing the parameter information read after processing each message into the new verification file, all verification files corresponding to the interference safety file are obtained.

[0065] S2: By specifying the interference safety file path and the verification file path in step S13, all file name paths under the two paths are read into buffer 1 and buffer 2 respectively, and then each file is traversed from buffer 1 and buffer 2, and each file content in buffer 1 is stored in buffer 3, and each file content in buffer 2 is stored in buffer 4. Compare the data in buffer 3 and buffer 4, so as to automatically complete the data verification.

[0066] The embodiments of the present invention provide a lightweight data verification method and system for nuclear medicine imaging equipment, which solves the problem in the prior art that the accuracy of each data cannot be verified through a process due to the huge amount of data.
