The key of transmitting and receiving is to calculate the parameter sequences of different array elements at different time.
For transmit and receive, focusing (beamforming) is performed at different times for each sounding depth, and delay values need to be calculated, which results in a high computational complexity. Moreover, the process of calculating the delay value and the focus processing is not only complex but also has a large data size, which easily causes hardware implementation to consume more resources. In addition, the ultrasonic system is fused with different imaging modes in the actual operation process, so that the requirement on hardware time sequence control is very high.

In order to facilitate understanding of the scanning control method of the medical ultrasonic apparatus provided in the embodiments of the present application, the following further describes the scanning control method with reference to the accompanying drawings.
As shown in fig. 3, a flowchart of a scan control method of a medical ultrasound apparatus in an embodiment of the present application is schematically illustrated, and the method includes the following steps:
in step 301, a user control command is generated in response to a configuration operation on a scanning parameter in a user interface;
in step 302, a target parameter set associated with the user control command is obtained from a plurality of pre-stored parameter sets; the target parameter set comprises static parameters and dynamic parameters corresponding to the user control commands, wherein the static parameters are parameters which cannot change in the scanning control process, and the dynamic parameters are parameters which change based on user operation;
first, before executing the scan control method of the medical ultrasound apparatus provided in the embodiment of the present application, a number of parameter sets may be calculated in advance in an offline manner, and the parameters in the parameter sets are stored according to a specified data organization structure. So as to calculate in advance and set all possible dynamic variation parameter combinations and static parameters required under different scanning control requirements. In practice, the target parameter set may be generated according to the following method:
step A1: acquiring the predetermined static parameters;
step A2: obtaining a parameter combination of parameters configured by the configuration operation;
step A3: executing the processing operation corresponding to the parameter combination according to the parameter combination to obtain a dynamic parameter corresponding to the user control command;
step A4: and generating the target parameter set according to the static parameters and the dynamic parameters.
It should be noted that the execution timing of step a1 is not limited. The static parameters and dynamic parameters are further described below.
Regarding the static parameters:
fig. 4 is a schematic structural diagram of an organization of static parameters provided in the embodiment of the present application. The off-line static parameters include probe status parameters, inspection mode status parameters, image mode status parameters, global status parameters, frequency status parameters, and focus status parameters. Wherein:
the priority of the probe state parameters is higher than that of all other state parameters, and the probe state parameters comprise parameters such as probe type, radius, arc length, width, array element number, array element physical width and the like;
under a certain probe, state parameters of examination modes are distinguished, a linear array probe comprises examination modes of thyroid, carotid, small organs and the like, a convex array comprises examination modes of abdomen, kidney and the like, and a phased array comprises examination modes of adult heart, pediatric heart and the like;
the inspection mode state parameters include image mode state parameters including B (brightness modulation), C (color Doppler), PW (pulse Doppler), M (spot scanning), CW (continuous Doppler) and other image modes;
each image mode state parameter is subdivided into a global state parameter, a frequency state parameter and a focus state parameter.
As shown in fig. 4, all parameter states organize the parameter structure in a hierarchical progression. The ultrasound system comprises a plurality of probes, all of which organize the parameter structure according to the above logical progression relationship.
The parameters for each combination (e.g., a certain image mode for a certain inspection mode for a certain probe) are calculated off-line to obtain a set of transmit and receive states (i.e., a set of static parameters). As shown in fig. 5, the state set may include a high-voltage switch state set, a transmission delay state set, a transmission waveform state set, a pulse repetition period state set, a line timing control set, and a simulation gain state set, and the parameters in the transmission and reception state set are calculated in advance from the corresponding probe state parameters, inspection mode parameters, and image mode parameters according to the combination rule and the preset.
Regarding the dynamic parameters:
and after the user operates the user UI interface to set the corresponding scanning parameters, forming a user control instruction and searching the corresponding dynamic parameters based on the user control instruction. That is, the corresponding parameters may be calculated in advance according to different user parameter combinations and stored in the parameter set, so as to determine which parameters should be used according to the user control command.
In the embodiment of the present application, in order to simplify the operation, a corresponding parameter value may be defined for each scan parameter, and the parameter value may be associated with an address of a corresponding target parameter set. For example, the address of each parameter set is represented by a bit sequence; responding to the configuration operation of the scanning parameters in the user interface, and acquiring a user command carrying the configured parameter values; replacing the value of a bit corresponding to the configured parameter in the bit sequence of the current parameter set with the parameter value to obtain the address of the target parameter set; and then, acquiring the target parameter set according to the address of the target parameter set.
That is, assuming that the definition of the user command is a table lookup tag, the tag value represents the address of the parameter set, assuming that the user command consists of N control words, each control word contains Mbit bits, and W represents the meaning of different Bit fields, the W definition may contain the mode of the current image, the transmission frequency number, the transmission focus, the number of the transmission focuses, whether it is a positive or negative harmonic, the transmission line number, the deflection angle number, the spatial composite angle number, the synthetic aperture switch, and other parameters related to transmission, when the user operates the UI in real time to configure the related scanning parameters, only the corresponding W field is updated, and the required parameters may be obtained for scanning control without complex operation processing.
In some embodiments, it is assumed that the transmit and receive control command set is defined as txrxcontrol cmd, the data depth is j, the field width is i, different Bit bits define different field-meaning, the field is defined as W (i, j), and thus the organization of the data is as shown in fig. 6: in fig. 6, each row represents a block of fields, each of which may index into one or more parameter sets.
In another embodiment, the target parameter set indexed according to the user control command may include one or more of the index parameter sets shown in fig. 6, and in a specific implementation, the target parameter set may be set according to an actual requirement, which is not limited in this application.
In some embodiments, after the required static parameters and dynamic parameters are obtained, in order to meet the storage requirement, the static parameters and the dynamic parameters may be subjected to fusion processing to obtain scan control parameters meeting the storage format requirement of the memory; then, storing the preset scanning control parameters belonging to the hardware memory in the scanning control parameters into the hardware memory; and storing the preset scanning control parameters belonging to the FPGA in the scanning control parameters into the FPGA. Therefore, the FPGA is used for storing some time-critical data by utilizing the advantage of high communication speed between the FPGA and the front-end probe, and then other data are stored in an external hardware memory. In addition, the shortage of the storage capacity of the FPGA can be made up, so that the external hardware memory can be used for storing required data as much as possible.
In some embodiments, the blending rule required for performing the blending process may be set according to the hardware memory rule, and different hardware memory characteristics may correspond to different blending rules. When the method is implemented, the static parameters can be sent to an external hardware memory, and the real-time dynamic parameter set is updated in real time and stored in the FPGA.
Through parameter fusion, dynamic parameters and static parameters can participate in front-end scanning control (such as transmitting, receiving, high-voltage control and the like), the scanning control has fixed parameter arrangement requirements, and after the dynamic parameters and the static parameters are respectively obtained, the dynamic parameters and the static parameters are required to be arranged and combined according to the scanning control flow and the parameter arrangement requirements of hardware, so that the parameter fusion process is completed.
Thus, after preparing the parameter sets required for scan control, the method as shown in fig. 3 in the embodiment of the present application may be performed.
In step 303, a scan control instruction is generated according to the dynamic parameter and the static parameter, and the medical ultrasound device is instructed to execute a scan operation according to the scan control instruction.
When the dynamic parameters and the static parameters are stored in the memory, the corresponding scan control parameters can be read from the hardware memory and the FPGA to generate a corresponding scan control command. Therefore, a small amount of real-time dynamic parameters are generated in real time according to user operation, the generation mode only needs to search corresponding dynamic parameters according to user control instructions, complex logic operation is not needed, static parameters are preset in an off-line mode, and complex real-time operation is not needed. Therefore, the embodiment of the application can simplify the operation amount and reduce the consumption of hardware resources.
In addition, the scanning control method of the medical ultrasonic equipment provided by the embodiment of the application can be compatible with different equipment, when a certain scanning control mode is added, a parameter set corresponding to the scanning control mode can be generated, the scanning control mode can be used in combination with user operation, hardware resources of operation processing do not need to be expanded additionally, and FPGA and software are not needed to be combined for operation.
Based on this, in the embodiment of the present application, the parameter set may be maintained and updated. The method can be implemented to respond to the user operation of updating the parameter set and acquire the parameter set to be updated; and then updating the pre-stored parameter set according to the parameter set to be updated. For example, when the user operates to add a new parameter set, if the front-end user interface does not need to be changed, it is only necessary to add a corresponding parameter set and add a corresponding control word in the table shown in fig. 6. When the parameters need to be modified, only the parameters in the parameter set need to be modified. Similarly, the deletion operation only needs to delete the corresponding parameter or parameter set.
In summary, the embodiment of the present application can provide a simple, easy to implement, fast, flexible, and highly compatible scan control method, which can be conveniently deployed in a terminal device, and simplify the implementation of an FPGA.
The following describes an example of reading a scan control instruction to control a medical ultrasound apparatus to perform scan control in the embodiment of the present application with reference to fig. 7.
In step 701, in response to the start operation, a default serial number of the transmission/reception control command is obtained.
In step 702, a sending and receiving control command set corresponding to the command sequence number in step 701 is obtained to obtain default dynamic parameters and static parameters for starting.
In step 703, a user control command is generated in response to a user configuring operation of a scan parameter in a user interface.
For example, as shown in fig. 8, some scan parameters that are set as needed may be provided in the user interface, after the step 702 is executed, default scan parameters may be provided in the user interface, and after the user modifies the default scan parameters, the step 703 is executed to generate a user control command.
As shown in fig. 7, the parameter values of the user control command include a transmission line number, a transmission waveform number, a pulse repetition period number, and an analog gain number. These four sequence numbers can be used as index addresses of the corresponding parameter sets, and the corresponding parameter sets are searched according to each sequence number.

The high-voltage switch address and the transmission delay address can be guided according to the label combination set by a user. A lucky high-voltage switching state set can be found by the high-voltage switching address, and then the high-voltage switching device can be controlled based on the high-voltage switching state set.
Similarly, a set of transmit delay states can be indexed by transmit delay address. Meanwhile, the transmitting waveform state set can be indexed according to the transmitting waveform sequence number, and then the waveform generating device is cooperatively controlled according to the parameters in the transmitting delay state set and the transmitting waveform state set.
And similarly, the pulse repetition period set can be guided by adopting the pulse repetition period sequence number, the line time sequence control set can be guided according to the parameters in the transmission line number, and then the FPGA is controlled by adopting the pulse repetition period set and the parameters in the line time sequence control set in a cooperative manner.
Similarly, the analog gain state set, the AFE (Active Front End) LNA (low noise amplifier), the set of detector parameters, and the set of low pass filter coefficients can be guided by the analog gain index, and the parameters in these sets are used to control the analog Front End devices.
It should be noted that the parameters for controlling the corresponding devices are included in each set, and the division and naming of the sets can be set according to actual needs, and fig. 7 is only an example.
