[0002] Ultrasound imaging, as a non-invasive and rapid examination method, is widely used in the field of medical diagnosis. Its basic principle is to generate high-voltage pulses through a control circuit, which are then converted into sound waves by an ultrasound transducer and transmitted into the human body. Different tissues and organs within the body respond differently to sound waves; at these density discontinuities, the sound waves are reflected, forming ultrasound echo signals. After the ultrasound transducer converts these echo signals into electrical signals, the subsequent circuitry acquires, calculates, and processes them to form an ultrasound image.

[0048] The method embodiments provided in this example can be executed on a terminal, computer, or similar computing device. For example, it can run on a terminal. Figure 1 This is a hardware structure block diagram of the terminal of the ultrasonic wave emission method in this embodiment. (See diagram for example.) Figure 1 As shown, a terminal may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 and a memory 104 for storing data are also included.

[0051] This embodiment provides an ultrasonic wave emission method. Figure 2 This is a flowchart of the ultrasonic wave emission method in this embodiment, as shown below. Figure 2 As shown, the process includes the following steps:

[0052] Step S210: In response to the trigger signal, acquire waveform configuration information of the target ultrasonic wave;

[0053] Step S220: Based on the waveform index in the waveform configuration information, parse the transmit waveform corresponding to each channel from the waveform lookup table;

[0054] Step S230: Based on the delay index in the waveform configuration information, parse the delay value corresponding to each channel from the transmission delay table;

[0055] Step S240: Based on the transmitted waveform, delay value, and channel transmission enable information in the shape configuration information, a high-voltage pulse is generated to drive the corresponding channel of the ultrasonic transducer to control the focusing of the transmitted target ultrasonic wave shape.

[0056] Specifically, the ultrasonic wave emission method of this application is applicable to ultrasonic equipment, which includes a client, a programmable logic array (FPGA), and an ultrasonic transducer. The client can be a mobile terminal, a fixed terminal, or a portable terminal, such as a mobile phone, device, multimedia computer, multimedia tablet, desktop computer, laptop computer, notebook computer, netbook computer, tablet computer, personal communication system (PCS) device, personal navigation device, gaming device, or any combination thereof, including accessories and peripherals of these devices, or any combination thereof. The ultrasonic transducer is a device that converts electromagnetic energy into mechanical energy (acoustic energy), typically made of piezoelectric ceramics or other magnetostrictive materials, and has multiple working channels.

[0057] Users can configure the waveform information of the target ultrasonic wave pattern in the client according to the transmission requirements and generate a trigger signal. Then, the waveform configuration information and trigger signal are sent to the programmable logic array to execute the ultrasonic wave transmission method described above. This causes a high-voltage pulse to drive the ultrasonic transducer, forming an ultrasonic mechanical wave. By controlling the polarity, period, and delay of the high-voltage pulse, the corresponding channel of the ultrasonic transducer is controlled, thereby indirectly controlling the direction and intensity of the ultrasonic wave transmission. This allows for scanning and imaging of organs at specific depths and angles in the human body.

[0058] A complete waveform can be broken down into several smaller waveform segments, which are indexed into a complete waveform using waveform indices. Scanning imaging requires multiple transmissions and receptions; each transmission and reception is called an ultrasound shot. Therefore, a single scanning imaging operation requires multiple shots. Waveform configuration information includes all the information for a single scanning imaging operation, including the waveform index, delay index, and channel transmit enable (Tx enable). The entire ultrasonic wave transmission method can be controlled by a global state machine. Upon receiving a trigger signal, it parses the waveform configuration information to obtain the waveform index, delay index, and channel transmission enable. Based on the waveform index, it retrieves the transmission waveform corresponding to each channel currently being emitted by the ultrasonic transducer from the waveform lookup table. Based on the delay index, it retrieves the delay value corresponding to each channel currently being emitted by the ultrasonic transducer from the transmit delay table. After each channel waits according to the obtained delay value, a high-voltage pulse is generated according to the transmission waveform corresponding to the waveform index. Based on the channel transmission enable, the relevant channels of the front-end transducer are driven. The ultrasonic mechanical waves output from the relevant working channels in the transducer interfere and superimpose in space, thus forming the focusing and deflection of the ultrasonic wave transmission. Figure 3 As shown.

[0059] Through the above steps, in response to the trigger signal, the waveform configuration information of the target ultrasonic wave is acquired. Based on the waveform index in the waveform configuration information, the transmitted waveform corresponding to each channel is parsed from the waveform lookup table, enabling independent waveform configuration for each channel without needing to store all complete waveforms, thus reducing resource occupancy. Based on the delay index in the waveform configuration information, the delay value corresponding to each channel is parsed from the transmission delay table; values ​​with the same delay can be reused, further reducing resource occupancy. Based on the transmitted waveform, delay value, and channel transmission enable in the waveform configuration information, a high-voltage pulse is generated to drive the corresponding channel of the ultrasonic transducer to control the focusing of the transmitted target ultrasonic wave. This solves the problem in related technologies where storing complete waveforms limits the number of waveforms and results in high resource occupancy. Waveform configuration is achieved, increasing the number of waveforms selectable under the same resource conditions and reducing resource occupancy.

[0060] The waveform lookup table will be explained below:

[0061] In some embodiments, the waveform lookup table is a depth table organized by rows; each row represents a waveform element.

[0062] The first waveform element in a series of consecutive waveform elements is used as the start address, and the last waveform element is used as the end address, forming a waveform unit of one cycle.

[0063] Specifically, the waveform lookup table stores various waveform elements, and its data structure is as follows: Figure 4 As shown, the waveform lookup table is a depth table based on rows, with a total depth of 1024. Each row represents a waveform element, and there are 1024 possible waveform elements, which can form all the waveforms required during the transmission process. By combining K1 consecutive waveform elements, the smallest period waveform unit of the transmitted waveform is formed. For example, if K1 is 4, the starting address is waveform element0, and the ending address is waveform element3, then the waveform elements from waveform element0 to waveform element3 form a smallest period waveform unit.

[0064] Each waveform occupies a contiguous address space in the waveform lookup table. Each waveform has its own start and end addresses. Instead of directly sending the start and end addresses of the waveforms, a waveform index is sent for each channel. The start and end addresses of the target waveform are then parsed from the waveform index, thus saving space. For example, if the waveform lookup table has a depth of 1024 and stores four waveforms, each waveform's start and end addresses would require 10 bits. Writing the start and end addresses in pairs into a register and then sending them as waveform parameters using a 2-bit waveform index saves storage space compared to sending 10 bits * 2.

[0065] The waveform element is defined as follows: bits 15 to 13 are used to encode the five-step transmit level, and bits 12 to 0 are used for the continuous transmit clock period T_wfe of this level.

[0066] In some embodiments, step S220, which involves retrieving the transmit waveform corresponding to each channel from the waveform lookup table based on the waveform index in the waveform configuration information, includes the following steps:

[0067] Step S221: Parse the waveform index in the waveform configuration information to obtain the start address and end address of the waveform unit; the waveform unit corresponds to the channel of the ultrasonic transducer;

[0068] Step S222: Using the start and end addresses of the waveform unit as conditions, parse the transmit waveform corresponding to each channel from the waveform lookup table.

[0069] Specifically, a waveform index corresponds to one or more waveform units; parsing the waveform index yields multiple pairs of start and end addresses; each pair of start and end addresses corresponds to a waveform unit; using the start and end addresses of the waveform units as conditions, the transmit waveform corresponding to each channel is parsed from the waveform lookup table.

[0070] For example, the two pairs of start and end addresses parsed from the waveform index are: waveform element0~waveform element3; waveform element4~waveform element7; corresponding to two waveform units respectively. Waveform elements0~waveform element3 retrieve the corresponding waveform elements from the waveform lookup table and combine them to form the transmitted waveform A; waveform A is transmitted by channel A of the ultrasonic transducer. Waveform elements4~waveform element7 retrieve the corresponding waveform elements from the waveform lookup table and combine them to form the transmitted waveform B; waveform B is transmitted by channel B of the ultrasonic transducer. The waveform corresponding to each channel of the ultrasonic transducer can be configured independently, realizing complex waveform combination transmission, thereby improving the flexibility of use.

[0071] In some embodiments, step S230, which involves resolving the delay value corresponding to each channel from the transmission delay table based on the delay index in the waveform configuration information, includes the following steps:

[0072] Step S231: Parse the delay index in the waveform configuration information to obtain the table name and number of channels;

[0073] Step S232: Based on the table name and the number of channels, parse the delay value corresponding to each channel from the transmission delay table.

[0074] Specifically, the transmit delay table stores the delay values ​​corresponding to the transmit delay curves, and one or more transmit delay tables are stored according to the ultrasonic transmit mode.

[0075] Before transmitting the waveform, the delay index is parsed to obtain the table name and the number of channels. Based on the table name and the number of channels, the target transmission delay table is parsed from multiple transmission delay tables. Then, the delay value corresponding to each channel is parsed from the target transmission delay table and sent to the channel delay unit for each channel. The delay timing unit is used for independent timing of each channel. Assuming N_tdt delay tables are stored, the depth of this representation is N_tdt*K2, such as... Figure 5 As shown, this implements the reuse of a delay curve in multiple transmission processes.

[0076] In some embodiments, step S240, which generates a high-voltage pulse to drive the corresponding channel of the ultrasonic transducer based on the transmitted waveform, delay value, and channel transmission configuration information to control the focusing of the transmitted target ultrasonic wave shape, includes the following steps:

[0077] Step S241: After each channel reaches the corresponding delay value, generate a corresponding waveform control signal based on the transmitted waveform.

[0078] Step S242: Based on the channel transmit enable, determine whether to output the corresponding waveform control signal;

[0079] In step S243, when outputting the waveform control signal, a high-voltage pulse is generated through the waveform control signal to drive the ultrasonic transducer in order to control the focusing of the ultrasonic wave pattern of the emitted target.

[0080] Specifically, after the delay timing unit of each channel reaches the corresponding delay value, it generates a corresponding waveform control signal based on the transmitted waveform. Each channel can have an independent channel transmit enable. Based on the channel transmit enable, it is determined whether to output the corresponding waveform control signal. When outputting the waveform control signal, each channel uses a 2-bit waveform loop index (waveform_loop_index) to indicate the number of waveform loop repetitions (waveform_loop_number). A high-voltage pulse is generated through the corresponding waveform control signal to drive the ultrasonic transducer and control the focusing of the ultrasonic wave pattern of the transmitted target. By using an index method, the number of waveform loops for each channel is avoided, reducing the use of BRAM on the FPGA and further reducing resource occupancy.

[0081] In some embodiments, the ultrasonic wave emission method further includes the following steps:

[0082] After obtaining the waveform configuration information of the target ultrasonic wave, the emission cycle group is integrated according to the waveform configuration information to generate an ultrasonic emission parameter control table.

[0083] Specifically, the ultrasound emission parameter control table (shot configuration table) includes all waveform configuration information for a single scan imaging, i.e., it includes multiple shots; it can be considered to include the waveform index, delay index, and channel emission enable (Tx enable) required to generate the waveform.

[0084] During ultrasonic transmission, all the shots required to complete one scan imaging are called a frame. In actual transmission, there are combinations of shots within a frame that need to be transmitted repeatedly. To reduce the storage resource requirements on the FPGA, K3 (K3≥1) adjacent shots are grouped into a transmission loop group. Three fields are defined in the ultrasonic parameter control table: group_loop_start, group_loop_end, and group_loop_index. Among them, group_loop_start indicates the first shot of the transmission loop group, group_loop_end indicates the last shot of the transmission loop group, and group_loop_index is used to query group_loop_register to determine the number of cycles of the current transmission loop group.

[0085] In other embodiments, to reduce parsing complexity, the intra-frame shot group loop does not support nested loops. One shot occupies N_shot double words, and a single transmission uses K4 configurations; therefore, the depth of the ultrasonic transmission parameter control table is K4*N_shot, as shown below. Figure 6 As shown.

[0086] The implementation of the transmit loop group involves three fields in the first double word of each shot configuration: the `group_loop_start` flag, the `group_loop_end` flag, and the `group_loop_index`. The `group_loop_start` flag is set to 1 for the first shot of the transmit loop group, and the `group_loop_end` flag is set to 1 for the last shot. The `group_loop_index` is obtained by accessing the `group_loop_number` register array to retrieve the current transmit loop group cycle count. Figure 7 As shown, by using a shot group, the transmit control parameters can be compressed and stored, reducing the demand for internal FPGA storage space.

[0087] In some embodiments, the ultrasonic wave emission method further includes the following steps:

[0088] In the client, the waveform configuration information of the target ultrasonic wave is configured according to the transmission requirements, and a trigger signal is generated.

[0089] Specifically, users can select the relevant probe (ultrasound transducer) in the client according to clinical needs, and configure the scanning mode, depth, working voltage, etc., so as to obtain the waveform configuration information of the target ultrasound shape.

[0090] In this embodiment, the waveform configuration information of the target ultrasonic wave can be configured independently in the client, which is convenient for users. Combined with the embodiment of the ultrasonic wave transmission method, it is possible to realize the transmission of ultrasonic B mode, PW mode, Color mode, CW mode single mode and multiplex mode.

[0091] It should be noted that the steps shown in the above process or in the flowchart of the accompanying figures can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
