Background
When the density of the pathological tissues or organs is close to that of normal tissues in the scanning examination, the pathological tissues are not easy to display, a contrast medium is generally required to be introduced into a patient body or a main body of the patient, and the quantity and distribution of the absorbed contrast medium have respective characteristics and rules due to different tissue structures and different pathological properties. Therefore, by injecting a contrast medium during scanning, contrast of a scanned image can be enhanced, a boundary between a diseased tissue and a normal tissue can be defined, and density, morphology and size can be highlighted, thereby facilitating detection and diagnosis of a disease.
In the process of scanning by the medical scanning system in a linkage control high-pressure injection system, the high-pressure injection system needs to acquire injection parameters corresponding to the scanning parameters in the medical scanning system, so that the injector performs high-pressure injection according to the injection parameters. Taking CT (Computed Tomography) as an example, in the related art, in the process of scanning by using a CT linkage control high-pressure injector, injection parameters are generally issued from a CT end to the injector, and the issuing flows are all parameters for issuing one-time injection protocols at a time.

The embodiment provides a linkage scanning and injection method which is applied to linkage scanning and injection of a medical scanning system and a high-pressure injection system. Fig. 2 is a flow chart of a linked scanning and injection method according to an embodiment of the present application, as shown in fig. 2, the flow chart includes the following steps:
step S201, in a first scanning process in a plurality of scanning processes, the high-pressure injection system executes a first high-pressure injection operation according to a first injection parameter corresponding to the first scanning process in a plurality of groups of injection parameters; the injection parameters are acquired according to one-time injection parameter configuration operation, and each group of injection parameters in the injection parameters corresponds to one scanning process in a plurality of scanning processes of the medical scanning system one by one.
The multiple scanning processes refer to multiple scanning periods performed on the same patient or the same subject, each scanning period corresponds to one set of injection parameters, wherein multiple sets of injection parameters are obtained according to one injection parameter configuration operation, and compared with multiple injection parameter configuration operations in the related art, the multiple scanning periods can simplify the flow of the injection parameter configuration operations.
In the liver CT enhancement scanning process, 20 to 25 percent of liver parenchyma is supplied with blood by hepatic artery, and 75 to 80 percent of liver parenchyma is supplied with blood by portal vein. Thus, the enhancement of normal hepatic parenchymal CT enhancement scans is not evident at the hepatic arterial phase, but more evident at the portal venous phase. According to the blood supply characteristics of the liver, a double-stage scan consisting of an artery stage scan and a portal vein stage scan of the liver is usually adopted to know the blood supply condition of the focus in the liver and improve the detection rate of the focus in the liver. The injection parameters for a bi-phasic scan of the liver may be obtained according to a one-shot parameter configuration operation, where the injection parameters differ from scan item to scan item, including but not limited to contrast agent dose, flow rate, duration, and pressure range in this embodiment.
In step S202, the high pressure injection system enters a hold state after the first high pressure injection operation is completed.
The hold state refers to the high pressure injection system stopping the current high pressure injection operation and holding the high pressure injection system in the injection stop state. In the high-pressure injection system in the related art, after one high-pressure injection operation is completed, manual intervention is usually required to confirm whether the current high-pressure injection operation is completed, the current high-pressure injection operation is stopped under the condition that the current high-pressure injection operation is completed, injection parameters of the next high-pressure injection are configured, and the high-pressure injection operation is resumed after the configuration is completed, so that the operation is complex.
Compared with the prior art, the embodiment can automatically stop the current high-pressure injection operation after the high-pressure injection system completes one high-pressure injection operation, and the high-pressure injection system keeps an injection stop state, thereby simplifying the injection operation.
In step S203, upon receiving a start signal of a second scanning process, the high pressure injection system performs a second high pressure injection operation according to a second injection parameter corresponding to the second scanning process, wherein the second scanning process is a next scanning process of the first scanning process.
After performing the high pressure injection operation that completes the current scanning process, i.e., in a case where the high pressure injection system enters the hold state, the high pressure injection system may perform the next period of the high pressure injection operation according to the injection parameters of the next period by receiving a start signal of the next period of the scanning process. The starting signal of the next scanning process may be a resume injection command sent by the high-pressure injection system, or a resume injection command sent by the medical scanning system.
For example, in the process of liver dual-phase scanning, after the high-pressure injection operation of liver artery phase scanning is finished, the high-pressure injection system stops injection and enters a holding state until a start signal of liver portal vein phase scanning is received, and the high-pressure injection operation of liver portal vein phase scanning is executed according to corresponding injection parameters.
Through the steps, in the process of linkage scanning and injection, the flow of repeated configuration and confirmation of injection parameters is simplified, the problem of low linkage scanning and injection efficiency in the related technology is solved, and the beneficial effects of improving the linkage scanning and injection efficiency are realized.
The following will describe an implementation manner in which the high-pressure injection system automatically suspends the current high-pressure injection operation after performing one high-pressure injection operation, and maintains the high-pressure injection system in an injection suspended state.
Each of the plurality of sets of injection parameters includes: maintaining the operating parameters; the hold operating parameter is used to instruct the high pressure injection system to enter a hold state when executed by the high pressure injection system.
In the present embodiment, after the high pressure injection system performs one high pressure injection operation, the high pressure injection system may automatically suspend the current high pressure injection operation by reading the maintaining operation parameter, and maintain the high pressure injection system in the injection suspension state. The maintaining operation parameters can indicate that the high-pressure injection operation is finished, and can also indicate that the high-pressure injection operation is suspended for a preset time and then continues to perform injection. For example, during a liver bi-phase scan, the following injection parameters are configured: the contrast agent is 60% water-soluble iodine, the dosage is 1.5 ml-2 ml/kg, the flow rate is 3 ml-4 ml/s, and the injection is stopped. After the injection starts, the high-pressure injection system executes the high-pressure injection operation of the current scanning process by reading each injection parameter in the set of injection parameters until the current high-pressure injection operation is stopped under the condition that the injection parameter of 'stopping injection' is read, and enters a holding state to prepare the high-pressure injection operation of the next scanning process. Or the maintaining operation parameters can also be configured to be 'stop injecting and delay 10 s', and in the case that the high-pressure injection system reads 'stop injecting and delay 10 s', the high-pressure injection operation of the current scanning process is stopped, and the current high-pressure injection operation is resumed after 10 s.
In the course of performing a period of high-pressure injection operation, it may be necessary to set an interruption delay operation during the injection, and enter a period delay state, i.e., the same period of high-pressure injection operation is completed in multiple times. In order to implement the interrupt delay operation, in some embodiments, the holding operation is divided into a holding state and a delay state, where the holding operation parameter corresponding to the holding state is hold and the delay operation parameter corresponding to the delay state is hold state. The holding state is automatically triggered, namely after one-time high-pressure injection is finished, the high-pressure injection system automatically enters the holding state, the high-pressure injection system can exit the holding state only through local operation or remote control, and the next injection process is executed. The delay state is triggered manually, namely after receiving an instruction sent by a user for entering the delay state, the high-pressure injection system enters the delay state, and after the set delay time is over, the high-pressure injection system automatically executes the next injection process. As one embodiment, the hold state and the delay state of the injector may be differentiated based on injector hardware feedback in the high pressure injection system to avoid user confusion between the hold state and the delay state.
Before the high-pressure injection system of the embodiment performs the first-stage high-pressure injection operation on a certain main body, the medical scanning system acquires multiple groups of injection parameters according to one injection parameter configuration operation and sends the multiple groups of injection parameters to the high-pressure injection system.
In this embodiment, the medical scanning system may perform an injection parameter configuration operation according to each scanning process of the multiple scanning processes, that is, configure each set of injection parameters corresponding to each scanning process, complete configuration of multiple sets of injection parameters through only one injection parameter configuration operation, and issue the configured injection parameters to the high-pressure injection system,
taking CT enhanced scan of the liver as an example, the CT control end performs one-time injection parameter configuration operation on the injection parameters of artery phase scan and portal vein phase scan of the liver according to a specific scanning method to complete the configuration of the injection parameters of the double-phase scan of the liver, and issues the configured injection parameters to the high-pressure injection system at one time.
Alternatively, in some embodiments, the medical scanning system sends the injection parameters corresponding to each of the plurality of sets of injection parameters to the high pressure injection system before each of the plurality of scanning procedures begins.
In this embodiment, the medical scanning system can complete the configuration of multiple sets of injection parameters by one injection parameter configuration operation, and then send the injection parameters to the high-pressure injection system in stages.
As a specific implementation manner, in the process of performing CT enhanced scan on the liver, the CT control end performs an injection parameter configuration operation on the injection parameters of the arterial scan and the portal venous scan of the liver according to a specific scanning method to complete the configuration of the injection parameters of the bi-phase scan of the liver, and before the start of the liver scanning process of each phase, the injection parameters of the current liver scanning process are issued to the high-pressure injection system.
In some embodiments, the medical scanning system may further receive an injection parameter modification instruction before each scanning process in the multiple scanning processes starts, where the injection parameter modification instruction is used to modify at least one injection parameter in the multiple sets of injection parameters; the medical scanning system modifies at least one set of injection parameters according to the injection parameter modification instruction, and sends the injection parameters corresponding to each scanning process in the modified multiple sets of injection parameters to the high-pressure injection system before each scanning process in the multiple scanning processes is started.
After the current high-pressure injection operation is finished, the high-pressure injection system stops the current high-pressure injection operation and enters a holding state, and during the period, the medical scanning system can receive an injection parameter modification instruction, modify the injection parameters of which the high-pressure injection operation is not executed, and send the modified injection parameters to the high-pressure injection system. Through the steps, the injection parameters can be modified under the condition that one-time injection parameter configuration operation fails, so that the fault tolerance rate of parameter configuration is improved.
In some of these embodiments, the medical scanning system generates the plurality of sets of injection parameters according to the plurality of scanning procedures prior to the high pressure injection system performing the first high pressure injection operation according to a first injection parameter of the plurality of sets of injection parameters corresponding to the first scanning procedure.
The medical scanning system may associate corresponding scan parameters and injection parameters according to an enhanced scan site of a patient, and associate the injection parameters of the enhanced scan site with parameters of a scan protocol. In the CT enhanced scanning process, after a doctor selects an enhanced scanning part of a patient, a CT control end automatically loads scanning parameters and injection parameters; or, after the doctor selects the scanning protocol according to the enhanced scanning part of the patient, the CT control end automatically loads the injection parameters. By the scheme, before the high-pressure injection system executes the first high-pressure injection operation according to the first injection parameter corresponding to the first scanning process in the multiple groups of injection parameters, the injection parameters can be obtained according to the preset scanning parameters, the injection parameters do not need to be independently led in, the work of a doctor for memorizing the scanning injection protocol is reduced, and the error occurrence probability is reduced.
Fig. 3 is a flowchart of CT multi-phase enhanced scanning linkage injection according to an embodiment of the present application, and as shown in fig. 3, a CT end configures multi-phase injection parameters once in a multi-phase scanning process, a doctor can start next-phase linkage scanning and injection by clicking scanning without updating the injection parameters, and without repeating the manual confirmation step after completing the first-phase high-pressure injection operation in fig. 1, thereby saving the operation of the doctor in the multi-phase scanning linkage injection process and shortening the overall scanning time of a patient.
Currently, the number of phases that each manufacturer produces and manufactures injectors that support the maximum injection parameters to be configured varies, typically from 6 to 12. Fig. 4 is a schematic interface diagram of an injection protocol of a multi-session enhanced scan according to the related art, as shown in fig. 4, wherein the parameters included in the interface include a Fluid source (Fluid source), a flow rate (flow rate), a dose (Volume), a Duration (Duration), a Pressure range (Pressure limit), a notification (Reminders), and an operation interface, where a and B represent two different Fluid sources, and the operation interface is used for receiving instructions from a doctor or other users, such as start of injection, stop of injection, and exit of the interface. Typically, the physician needs to reconfigure the protocol parameters for the second injection to the injector after the first injection is completed, requiring several manual confirmation steps in between.
In combination with the linkage injection and scanning method of the present application, fig. 5 shows an interface schematic diagram of an injection protocol of the multi-phase enhanced scanning according to the embodiment of the present application, as shown in fig. 5, Hold represents a holding state, for a multi-phase injection parameter of the same patient, in the present embodiment, Hold is used as a distinguishing mark for different phases of injection in the multi-phase injection, and a corresponding holding operation parameter is Hold phase. After the injector executes the first injection protocol, the injector automatically jumps to the hold phase and stops the current high-pressure injection operation. The injector can respond to the injection recovery command of the local or remote CT end of the injector and can also respond to the modification of the phase parameter which is not injected after the hold phase. When the CT multi-period scanning linkage injection is carried out, a doctor issues the protocol parameters to the injector after completing the configuration of the protocol parameters at one time before the whole scanning process is started, and the parameters are confirmed to be correct. In the multi-period scanning, the multi-period linkage scanning process can be completed only by continuously clicking the CT end exposure key, exiting the Hold and recovering the injection, so that the processes of repeatedly issuing parameters and repeatedly confirming the parameters in the middle are reduced.
