Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The air correction method provided by the embodiment of the application can be applied to computer equipment shown in FIG. 1. The computer device comprises a processor and a memory connected by a system bus, wherein a computer program is stored in the memory, and the steps of the method embodiments described below can be executed when the processor executes the computer program. Optionally, the computer device may further comprise a network interface, a display screen and an input device. Wherein the processor of the computer device is configured to provide computing and control capabilities. The memory of the computer device includes a nonvolatile storage medium storing an operating system and a computer program, and an internal memory. The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium. The network interface of the computer device is used for communicating with an external terminal through a network connection. Optionally, the computer device may be a server, a personal computer, a personal digital assistant, other terminal devices such as a tablet computer, a mobile phone, and the like, or a cloud or a remote server, and the specific form of the computer device is not limited in the embodiment of the present application.
With the development of medical equipment, the medical equipment is widely applied, and generally, air correction is required to be performed on the medical equipment regularly, so as to remove ring-shaped or band-shaped artifacts which may be generated in a scanned image obtained when the equipment scans a patient, and further improve image quality. Taking a Computed Tomography (CT) apparatus as an example, with the development of CT products, the number of detector rows increases, especially increases to 320 rows, and the number of parameter combinations in air correction also increases correspondingly, if only one parameter combination is executed and calculated from top to bottom each time still according to the original method, considering the large amount of time consumption caused by frequent start-stop adjustment of hardware physical parameters, etc., executing air correction of nearly ten thousand parameter combinations will take nearly 10 hours, which will seriously affect the daily use of the CT apparatus. Therefore, it is necessary to provide an air correction method, an air correction apparatus, a computer device, and a storage medium, which solve the problem that the conventional air correction method is time-consuming.
In one embodiment, as shown in fig. 2, an air correction method is provided, which is exemplified by the method applied to the computer device in fig. 1, and includes the following steps:
s201, sequencing the single protocol variable hardware parameters in the correction parameters according to the time consumed by the change of the variable hardware parameters to obtain a first correction parameter sequence.
Specifically, the computer device may divide physical parameters of each hardware into a single protocol variable hardware parameter and a single protocol non-rigid part parameter according to whether a single protocol of the air correction supports change, and then sequence the single protocol variable hardware parameter in the correction parameters according to change time consumption of the variable hardware parameter to obtain a first correction parameter sequence. The single protocol variable hardware parameter refers to a parameter which supports change within an optional value in the protocol, and the single protocol non-rigid element parameter refers to a parameter which does not support change within an optional value in the protocol but can change between next protocols. Optionally, the computer device may place the variable hardware parameter that takes longer to change the single protocol variable hardware parameter in the correction parameters at a position where the parameter changes later in the first correction parameter sequence, and place the variable hardware parameter that takes shorter to change the single protocol variable hardware parameter in the correction parameters at a position where the parameter changes first in the first correction parameter sequence. Optionally, the correction parameters include: focus mode, focus position, focus size, bulb voltage, scanning resolution, rotation speed, and slice gear.
S202, sequencing the parameters of the single protocol non-rigid parts in the correction parameters according to the time consumption of the change of the parameters of the non-rigid parts to obtain a second correction parameter sequence.
Specifically, the computer device orders the single protocol non-rigid component parameter in the correction parameters according to the time consumption of the non-rigid component parameter, so as to obtain a second correction parameter sequence. Optionally, the computer device may place the non-hardenable piece parameter, which takes a long time to change the single protocol non-hardenable piece parameter in the correction parameters, at a position in the second correction parameter sequence where the parameters change later, and place the non-hardenable piece parameter, which takes a short time to change the single protocol non-hardenable piece parameter in the correction parameters, at a position in the first correction parameter sequence where the parameters change first.
S203, combining the first correction parameter sequence and the second correction parameter sequence into a plurality of parameter sets, adding the parameter sets into the correction protocol, and issuing the correction protocol.
Specifically, the computer device combines the first correction parameter sequence and the second correction parameter sequence into a plurality of parameter groups, adds the parameter groups to a correction protocol, and issues the correction protocol added with the parameter groups. Optionally, the computer device may randomly combine the correction parameters in the first correction parameter sequence and the correction parameters in the second correction parameter sequence to obtain a plurality of parameter groups, or combine the correction parameters in the first correction parameter sequence and the correction parameters at corresponding positions in the second correction parameter sequence to obtain a plurality of parameter groups.
In the air correction method, the computer equipment can sequence the variable hardware parameters of the single protocol in the correction parameters according to the time consumption for changing the variable hardware parameters to obtain a first correction parameter sequence, can sequence the non-rigid hardware parameters of the single protocol in the correction parameters according to the time consumption for changing the non-rigid hardware parameters to obtain a second correction parameter sequence, can combine the first correction parameter sequence and the second correction parameter sequence into a plurality of parameter groups, adds the combined parameter groups in the correction protocol, and issues the correction protocol.
In the above scenario that the single protocol variable hardware parameter in the correction parameters is sequenced according to the time consumed by the change of the variable hardware parameter to obtain the first correction parameter sequence, in an embodiment, as shown in fig. 3, the step S201 includes:
s301, placing the single protocol variable hardware parameter which is changed by more than a preset first threshold value in the single protocol variable hardware parameter in an inner loop of the first correction parameter sequence.
Specifically, the computer device puts the single protocol variable hardware parameter whose change time in the single protocol variable hardware parameter is larger than a preset first threshold value in an inner loop of the first correction parameter sequence. The inner loop of the first correction parameter sequence refers to a position of post-change in the first correction parameter sequence, that is, the computer device may place a single protocol-variable hardware parameter, which takes a relatively long time, in the inner loop of the first correction parameter sequence. It will be appreciated that the first sequence of correction parameters may be understood as a fully permuted combination, wherein a fully permuted combination refers to a sequence resulting from combining all possible combinations of parameters. For example, the inner loop of the first correction parameter sequence may be analogous to a variation of the hour, minute, second hand, minute or hour hand, the second hand varying fastest and the hour and minute hands varying relatively slowly, i.e. the inner loop of the first correction parameter sequence refers to the position of the latter variation.
S302, placing the single protocol variable hardware parameter with the time consumption less than or equal to a preset first threshold value in the single protocol variable hardware parameter in an outer loop of the first correction parameter sequence to obtain a first correction parameter sequence.
Specifically, the computer device places the single protocol variable hardware parameter, which takes less than or equal to the preset first threshold value in the single protocol variable hardware parameter, in an outer loop of the first correction parameter sequence to obtain the first correction parameter sequence. The outer loop of the first correction parameter sequence refers to a position which is changed in the first correction parameter sequence, that is, the computer device can put a single protocol-variable hardware parameter which consumes relatively short time into the outer loop of the first correction parameter sequence. Likewise, a first sequence of correction parameters may be understood as a fully permuted combination, wherein a fully permuted combination refers to a sequence resulting from combining all possible combinations of parameters. For example, the outer loop of the first correction parameter sequence may be analogous to the movement of the second hand among the hour, minute and second hands, the movement of the second hand being the fastest and the movement of the hour and minute hands being relatively slow, i.e. the outer loop of the first correction parameter sequence refers to the position of the first change. By such sorting, the variable hardware parameters which are relatively short in time consumption in the single protocol variable hardware parameters in the correction parameters can be changed relatively frequently, so that the total time consumption for changing the parameters is ensured to be short.
In this embodiment, the computer device places the single protocol variable hardware parameter whose change consumption time is greater than the preset first threshold value in the inner loop of the first correction parameter sequence, and places the single protocol variable hardware parameter whose change consumption time is less than or equal to the preset first threshold value in the single protocol variable hardware parameter in the outer loop of the first correction parameter sequence, so that the change of the variable hardware parameter whose change consumption time is shorter in the single protocol variable hardware parameter in the correction parameters is more frequent, thereby ensuring that the total consumption time is shorter when the parameters are changed, and reducing the consumption time of air correction.
In the above scenario that the single protocol non-rigid component parameter in the correction parameters is sorted to obtain the second correction parameter sequence when the non-rigid component parameter is changed, as shown in fig. 4, the step S202 includes:
s401, the single protocol non-hardnable piece parameter which changes the single protocol non-variable hardware parameter and consumes more than a preset second threshold value is placed in an inner loop of the second correction parameter sequence.
Specifically, the computer device puts the single protocol non-variable hardware parameter, which takes longer than a preset second threshold value when the single protocol non-variable hardware parameter changes, in an inner loop of the second correction parameter sequence. The inner loop of the second correction parameter sequence refers to a position of post-change in the second correction parameter sequence, that is, the computer device may put a single protocol non-rigid element parameter, which takes a relatively long time, into the inner loop of the second correction parameter sequence. It is to be understood that the second correction parameter sequence may be understood as a fully permuted combination, wherein a fully permuted combination refers to a sequence resulting from combining all possible combinations of parameters. For example, the inner loop of the second correction parameter sequence may be analogous to a variation of the hour, minute, second hand, minute or hour hand, the second hand varying fastest and the hour and minute hands varying relatively slowly, i.e. the inner loop of the second correction parameter sequence refers to the position of the latter variation.
S402, placing the single protocol non-rigid component parameter which takes less than or equal to a preset second threshold value in the single protocol non-variable hardware parameter in an outer loop of the second correction parameter sequence to obtain a second correction parameter sequence.
Specifically, the computer device puts the single protocol non-rigid component parameter, which takes less than or equal to the preset second threshold value to change in the single protocol non-rigid component parameter, in an outer loop of the second correction parameter sequence, so as to obtain the second correction parameter sequence. The outer loop of the second correction parameter sequence refers to a position of post-change in the second correction parameter sequence, that is, the computer device may put a single protocol non-stiffenable element parameter, which takes a relatively short time, in the outer loop of the second correction parameter sequence. Likewise, a fully permuted combination may be understood as a sequence of second correction parameters, wherein a fully permuted combination refers to a combination of all possible combinations of parameters. For example, the outer loop of the second correction parameter sequence may be analogous to the movement of the second hand in the hour, minute and second hands, the movement of the second hand being the fastest and the movement of the hour and minute hands being relatively slow, i.e. the outer loop of the second correction parameter sequence refers to the position of the previous change.
Illustratively, a single protocol in air correction has four sets of hardware parameters in total: the four groups of parameters are A (A1/A2), B (B1/B2), C (C1/C2) and D (D1/D2), wherein the parameter values in brackets are optional values of the parameters, if the value of the A parameter is only A1 or A2, 1 second is needed for changing the A parameter (namely 1 second is needed for changing the A parameter between A1 and A2, the time is considered to be not needed for keeping the A1 value unchanged from beginning to end), 2 seconds is needed for changing the B parameter, and the like, C and D are 3 and 4 seconds respectively. Assuming that a and B are single protocol variable parameters, C and D are single protocol non-variable parameters, if the system is issued according to the conventional air correction protocol, 2x2x2=16 air correction protocols are required, and the parameter combinations carried in each air correction protocol are as follows: if the sequence is A1B1C1D1, A1B1C1D2, A1B1C2D1, A1B2C2D2, A2B2C2D1, and A2B2C2D2, the peripheral parameter D is frequently changed between D1 and D2, which results in a lot of 4 seconds of long time consumption, and the sequence of the ABCD is reversed in the present application, so that the frequent change of the parameter a in the periphery results in a relatively short 1 second of time consumption (it should be noted that only D and a are used for comparison, and B and C are also actually changed and have corresponding time consumption), after the scheme of the present application is adopted, only 2x2=4 null-correction protocols need to be issued, and the carried parameter groups are respectively:
D1C1
B1A1
B1A2
B2A1
b2A2, (a changed 3 times, B changed only 1 time);
D1C2
B1A1
B1A2
B2A1
B2A2
D2C1
B1A1
B1A2
B2A1
B2A2
D2C2
B1A1
B1A2
B2A1
B2A2
since C and D are single protocol immutable parameters, only one combination of C and D can exist in a single protocol, and a and B are single protocol mutable parameters, all combinations of a and B can be included in a single protocol. After the first protocol is executed to the second protocol, C is changed instead of D, the changing time is reduced, and after the first protocol and the second protocol are sequenced, the time-consuming parameter which is relatively shorter is changed more frequently no matter between the first protocol and the second protocol or inside the first protocol, so that the execution of a large number of air correction protocols is ensured to be completed in the shortest time, the overall time consumption is reduced, multiple execution cycles are avoided, all air correction is executed in a short time at one time, the timeliness of a generated correction table is really guaranteed, and the occurrence of clinical image artifacts is further avoided.
In this embodiment, the computer device places the single protocol non-rigid component parameter, whose change time consumption is greater than the preset second threshold, in the inner loop of the second correction parameter sequence, and places the single protocol non-rigid component parameter, whose change time consumption is less than or equal to the preset second threshold, in the non-variable hardware parameter in the single protocol in the outer loop of the second correction parameter sequence, so that the non-rigid component parameter, whose change time consumption is shorter in the single protocol non-rigid component parameter in the correction parameters, is changed more frequently, thereby ensuring that the total time consumption is shorter when changing the parameters, and reducing the time consumption for air correction.
In the above scenario of obtaining the first correction parameter sequence and the second correction parameter sequence, the computer device needs to first determine a single protocol variable hardware parameter and a single protocol non-rigid hardware parameter in the correction protocol, and on the basis of the foregoing embodiment, in an embodiment, the method further includes: and determining a single-protocol variable hardware parameter and a single-protocol non-rigid hardware parameter in the correction protocol according to a preset determination condition.
Specifically, the computer device determines a single protocol variable hardware parameter and a single protocol non-rigid hardware parameter in the correction protocol according to a preset determination condition. The single protocol invariable hardware parameter refers to a parameter which does not support to be changed in a selectable value in a single correction protocol by considering hardware and software design reasons, and the number of executed correction protocols is determined according to the combination of the parameters; the single protocol variable hardware parameter is a parameter that supports variation within a selectable value in a single correction protocol, taking hardware and software design reasons into consideration. Optionally, the computer device may determine whether the hardware physical parameter in the single protocol supports change according to the hardware parameter of the target device, and divide each hardware physical parameter in the correction protocol into a single protocol variable hardware parameter and a single protocol non-variable hardware parameter, that is, the preset determination condition may be the hardware parameter of the target device.
In this embodiment, the computer device can quickly determine the single protocol variable hardware parameter and the single protocol non-variable hardware parameter in the correction protocol according to the preset determination condition, and the efficiency of determining the single protocol variable hardware parameter and the single protocol non-variable hardware parameter in the correction protocol is improved.
In a scenario where the computer device combines the first correction parameter sequence and the second correction parameter sequence into a plurality of parameter sets, adds the parameter sets to the correction protocol, and issues the correction protocol, the computer device further obtains a correction table corresponding to the physical parameters of each hardware device. In one embodiment, as shown in fig. 5, the method further includes:
s501, controlling each hardware device of the computed tomography imaging device to adjust the physical parameters according to the correction protocol to obtain the adjusted physical parameters.
Specifically, the computer device controls each hardware device of the Computed Tomography (CT) device to adjust the physical parameters according to the issued correction protocol, so as to obtain the adjusted physical parameters. That is, the computer device controls each hardware device of the CT device to adjust the physical parameters of each hardware device of the CT device according to the plurality of parameter groups in the issued calibration protocol, and obtains the adjusted physical parameters.
And S502, obtaining a correction table corresponding to the physical parameters of each hardware device according to the adjusted physical parameters.
Specifically, the computer device obtains a correction table corresponding to the physical parameters of each hardware device of the CT device according to the obtained adjusted physical parameters. Optionally, the computer device may compare the physical parameters of each hardware device of the CT device with the obtained adjusted physical parameters of each hardware device of the CT device, so as to obtain a correction table corresponding to the physical parameters of each hardware device of the CT device.
In this embodiment, the computer device controls each hardware device of the computed tomography apparatus to accurately adjust the physical parameters according to the correction protocol, so that the adjusted physical parameters with higher accuracy can be obtained, and further, the correction table corresponding to the physical parameters of each hardware device of the computed tomography apparatus can be accurately obtained according to the obtained adjusted physical parameters with higher accuracy.
In the scenario that the correction table corresponding to the physical parameter of each hardware device of the CT device is obtained according to the adjusted physical parameter, in an embodiment, the step S502 includes: and controlling each hardware device of the computed tomography imaging device to acquire data by adopting the adjusted physical parameters, and performing parallel computation on the acquired data to obtain a correction table corresponding to the physical parameters of each hardware device.
Specifically, the computer device controls each hardware device of the CT device to acquire data by using the adjusted physical parameters, and performs parallel computation on the acquired data to obtain a correction table corresponding to the physical parameters of each hardware device of the CT device. That is, the computer device can control the CT device to transfer the processed air correction protocol to the hardware device of the CT device one by one during the execution of the air correction, the hardware device of the CT device continuously adjusts various parameters according to the received parameters in the correction protocol to complete data acquisition, and after the data acquisition is completed, the calculation unit performs parallel calculation to obtain the air correction table.
In this embodiment, the computer device controls each hardware device of the computed tomography apparatus to acquire data by using the adjusted physical parameters, and the process of performing parallel computation on the acquired data is very simple, so that the computer device can quickly obtain a correction table corresponding to the physical parameters of each hardware device of the computed tomography apparatus; in addition, the acquired data is acquired by controlling each hardware device of the computed tomography device by the computer device through the adjusted physical parameters, so that the computer device can obtain data with higher accuracy, the correction table corresponding to the physical parameters of each hardware device can be accurately obtained according to the acquired data with higher accuracy, and the accuracy of the correction table corresponding to the physical parameters of each hardware device of the computed tomography device is improved.
