The present invention relates to a DC motor control device, and more particularly to a DC motor control device.

Because ultrasonic is a non-invasive non-invasive technology and has high safety, it has been widely used in medical testing, and because of the improved imaging quality of ultrasound, the resolution and convenience are constantly improving, so whether it is in high-order 3D, 4D images and entry-level models all have a growing trend.

However, when the medical ultrasonic device is used, the Transducer generates a very short ultrasonic vibration in the vibration echo technology, and the piezoelectric polycrystalline ceramic (piezo-electric polycrystalline ceramic) used by the transmitter is used. The elasticity of the vibration is continued for a period of time after the vibration is terminated, so that the two ultrasonic units in the ultrasonic probe for generating ultrasonic signals interfere with each other, which affects the quality of the ultrasonic imaging, in order to reduce the effect, the current This is done by attaching a highly absorbent material to the back of the ceramics as a liner to block it, or by using back-end signals and/or image processing techniques to improve the aforementioned interference problems, but this is not effective in eradicating the source of the signal. problem.

Accordingly, it is an object of the present invention to provide a probe array image manipulation system and method for medical ultrasound that can improve interference problems from a signal source.

The probe array controller includes an address setting module, a mode setting module, and a startup control module. The address setting module can generate a plurality of address parameters respectively corresponding to the addresses. The mode setting module can sequentially arrange the address parameters to generate a startup sequence, and the addresses corresponding to the adjacent two address parameters of the startup sequence are not adjacent. The startup control module may generate a plurality of activation signals respectively corresponding to the address parameters of the startup sequence, and sequentially transmit the startup signals corresponding to the respective address parameters of the startup sequence to the specific time interval to the specific time. The ultrasonic probe transmits and receives an ultrasonic signal by respectively driving an ultrasonic unit corresponding to each address parameter.

Therefore, the method for image manipulation of the probe array image of the medical ultrasonic wave is applied to a medical ultrasonic device through a program software and/or an electronic circuit to control an ultrasonic unit having a plurality of arrays. An ultrasonic probe, wherein each of the ultrasonic units has an sequentially arranged address, and the probe array image manipulation method comprises the following steps: (A) causing the medical ultrasonic device to generate a plurality of corresponding addresses corresponding to the addresses Address parameters; (B) causing the medical ultrasonic device to sequentially arrange the address parameters to form a startup sequence, and the addresses represented by the two adjacent address parameters in the startup sequence are not adjacent: and (C) causing the medical ultrasonic device to generate a plurality of activation signals respectively corresponding to the address parameters of the startup sequence, and sequentially sequentially initiating the corresponding signal parameters corresponding to the start-sequenced address parameters at specific intervals The ultrasonic probe is transmitted to the ultrasonic unit corresponding to each address parameter to transmit and receive the ultrasonic signal.

The effect of the invention is that the ultrasonic array probe can be controlled by the probe array image manipulation system to sequentially start the design of the ultrasonic units by spacing at least one ultrasonic unit, and the traditional ultrasonic probe driving method can be improved. The resulting signal interference problem can greatly reduce the complexity of the back-end signal and image processing by directly improving the quality of the front-end output signal, and can effectively improve the quality of the ultrasonic image.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 1 and 2, an embodiment of the probe array image manipulation system for medical ultrasound of the present invention can be implemented in a medical ultrasonic device 800 by means of software programs and/or electronic circuits. The medical ultrasonic device is constructed. The 800 has a host 801, and an ultrasonic probe 802 connected to the control host 801. The host 801 has a touch-enabled touch display 804. The ultrasonic probe 802 has a plurality of matrix arrangements and respectively An ultrasonic unit 803 capable of transmitting an ultrasonic signal and sensing an ultrasonic signal, and the ultrasonic unit 803 respectively converts the ultrasonic signal sensed and received into an output signal of a telecommunication type, and outputs the ultrasonic unit. Each of the 803 sets an address that is sequentially arranged, for example, 1, 2, 3, 4, ....64. In the present embodiment, the ultrasonic probe 802 is described by taking 64 ultrasonic units 803 as an example, but in practice, it can also be applied to the ultrasonic probe 802 having 128 or 256 ultrasonic units 803. Since the medical ultrasonic device 800 is an existing device and has many types, the operation principle and function thereof are not described in detail, and the medical ultrasonic device 800 to be applied is not limited to the type of the drawing.

The probe array image manipulation system can be used to control the operation of the ultrasonic probe 802, and to process the ultrasonic probe 802 to sense the output signals output by the received ultrasonic signal. The probe array image manipulation system includes a probe array controller 3 for controlling the ultrasonic probe 802, and an image processor 4 for receiving the output signals for processing the output of the ultrasonic probe 802.

The probe array controller 3 is disposed in the ultrasonic probe 802 and includes an address setting module 31, a mode setting module 32, a startup control module 33, and a detection module 34. The address setting module 31 can generate a plurality of address parameters respectively corresponding to the addresses.

The mode setting module 32 is operable to set the activation mode of the ultrasonic units 803 of the ultrasonic probe 802. The mode setting module 32 has a parity starting mode 321 and an N interval starting mode 322 that can be selectively switched to be started. The mode setting module 32 can sequentially arrange all the address parameters representing the odd address when the parity start mode 321 is selected to start, to generate an odd unit sequence, for example, 1, 3, 5, 7...63 And sequentially arranging all address parameters representing even addresses to produce an even sequence of elements, such as 2, 4, 6, . . . 64. Then, the odd unit sequence and the even unit sequence are sequentially arranged to form a starting order, for example, 1, 3, 5, 7, . . . , 63, 2, 4, 6, 8, ..., 64, or 2 4, 6, 8, ..., 64, 1, 3, 5, 7, ..., 63, the starting sequence represents the sequence in which the ultrasonic units 803 are activated.

When the N interval start mode 322 is selected to be activated, the mode setting module 32 sequentially arranges all address parameters spaced apart from each other by N addresses according to the order of the addresses to form (N+1). Unit sequence. Where N is greater than or equal to 2, but less than an integer of 64, such as 2, 3, etc., but not limited thereto. Taking N=2 as an example, the address parameters of the addresses 1, 4, 7, 10, ..., 64 are sequentially arranged to form a unit sequence, and the addresses are 2, 5, 8, 11...62. The address parameters are sequentially arranged to form a unit sequence, and the address parameters of the addresses 3, 6, 9, 12...63 are sequentially arranged to form a unit sequence, which constitutes a total of three unit sequences. When N=3, the mode setting module 32 sequentially arranges the address parameters of the addresses 1, 5, 9, 13...61 to form a unit sequence, and the addresses are 2, 6, 10, 14... The address parameters of 62 are sequentially arranged to form a unit sequence, and the address parameters of the addresses 3, 7, 11, 15...63 are sequentially arranged to form a unit sequence, and the addresses are 4, 8, 12, 16 The address parameters of ... 64 are sequentially arranged to form a unit sequence, and a total of four unit sequences are generated.

After generating the unit sequences, the mode setting module 32 further sequentially arranges the unit sequences to form a startup order, for example, 1, 4, 7, ... 64, 2, 5, 8, ... 62, 3, 6 , 9...63, or 1, 5, 9, ... 61, 2, 6, 10...62, 3, 7, 11, ... 63, 4, 8, 12...64.

The startup control module 33 can generate a plurality of corresponding address parameters respectively corresponding to the startup sequence, and can respectively start the activation signals of the ultrasonic units 803, and sequentially start the intervals at specific intervals. The activation signals corresponding to the sorted address parameters are sequentially transmitted to the ultrasonic probe 802, for example, every 1 μsec, to drive the ultrasonic unit 803 corresponding to the address to transmit and receive the ultrasonic signals.

That is, the startup control module 33 activates the address parameters of the startup order of the mode 321 according to the parity number, for example, 1, 3, 5, 7, . . . , 63, 2, 4, 6, 8 ...., 64, or the sequence of units of the N interval start mode 322, for example 1, 4, 7...64, 2, 5, 8...62, 3, 6, 9...63, sequentially transmitting the start signal to The ultrasonic probe 802 sequentially activates the ultrasonic unit 803 corresponding to the address. Therefore, at the same time, only one ultrasonic unit 803 is activated, and the two ultrasonic units 803 adjacent to the address are not The sequence is sequentially activated, thereby avoiding the problem that the adjacent two ultrasonic units 803 of the address are sequentially activated to interfere with each other.

The detection module 34 can continuously detect whether the startup control module 33 is adjacent to multiple addresses in the address period when the startup control module 33 outputs the startup signals to drive the operations of the ultrasonic units 803. The address parameter sequentially sends the start signal, for example, sending the start signal to two address parameters adjacent to the address, or sequentially sending the start signal to three address parameters adjacent to the address, or The start signal is sent to the adjacent four address parameters in sequence.

If the detection module 34 detects that the startup control module 33 sequentially transmits the activation signal to the address parameters of multiple adjacent addresses, the detection module 34 drives the startup control module 33 to stop. The operation causes the ultrasonic probe 802 to stop, thereby preventing the ultrasonic unit 803 of the adjacent address from being disturbed by the sequential operation, and the detecting module 34 drives the host 801 to send an abnormal warning message. For example, a warning light, a warning sound, and/or a warning image; if the above situation is not detected, the ultrasonic units 803 of the ultrasonic probe 802 can be individually activated in sequence.

The image processor 4 is disposed on the host 801 and includes a unit image module 41 and an image synthesis module 42. When the parity start mode 321 of the mode setting module 32 is activated, the unit image module 41 receives and processes the ultrasonic probe 802 according to the ultrasonic signal received by the odd unit sequence. All output signals are used to generate a unit image, and receive and process all of the output signals generated by the ultrasonic probe 802 based on the received supersonic signals according to the even unit sequence to generate another unit image. When the N interval activation mode 322 of the mode setting unit is activated, the unit image module 41 receives all the outputs generated by the ultrasonic probe 802 according to the ultrasonic signals received by each of the unit sequences. Signals to generate a unit image corresponding to each unit sequence.

The image synthesizing module 42 can perform image synthesizing processing on the unit images generated by the unit image module 41, for example, superimposing the unit images to form a complete ultrasonic image.

Referring to Figures 1, 2 and 3, the probe array image manipulation method for medical ultrasonic waves of the present invention comprises the following steps:

Step (1) defines address parameters of the ultrasonic units 803. The address setting module 31 correspondingly generates a plurality of address parameters according to the addresses of the ultrasonic units 803.

Step (2) generates a startup sequence based on the address parameters. The parity start mode 321 or the N interval start mode 322 can be selected to be activated by operating the touch screen display 804 (not shown) according to the startup mode to be used, and can be started at the N interval. When the mode 322 is activated, the value of "N" is further set. Taking the parity start mode 321 as an example, the mode setting module 32 generates the boot sequence formed by sequentially arranging the odd cell sequence and the even cell sequence.

Step (3) sequentially controls the ultrasonic probe 802 according to the startup sequence. And causing the startup control module 33 to generate a plurality of activation signals respectively corresponding to the address parameters of the startup sequence, and according to the order of the address parameters of the startup sequence, the startup signals are The ultrasonic probes 802 are transmitted to the ultrasonic transducers 802 to cause the ultrasonic units 803 to transmit and receive ultrasonic signals in a specific order.

Step (4) detecting whether the adjacent ultrasonic units 803 are sequentially activated. The detecting module 34 is configured to continuously detect whether two or more adjacent address addresses of the ultrasonic unit 803 are sequentially executed during the activation of the ultrasonic unit 803 by the activation control module 33. In the case of startup, for example, whether the ultrasonic unit 803 whose address is "10" or "11" is connected to be activated, and if the ultrasonic unit 803 of the adjacent two addresses is successively activated, the startup control mode is driven. The group 33 stops operating, and at the same time drives the host 801 to issue the abnormal warning message, thereby reminding the operator to check whether the device is abnormal.

Step (5) produces a unit image. After the ultrasonic probe 802 is driven according to the start sequence, the ultrasonic units 803 respectively sense the received ultrasonic signals and convert the output signals of a telecommunication type. In the case of starting the parity start mode 321 , the unit image module 41 receives and processes all the output signals output by the ultrasonic probe 802 according to the odd unit sequence and the even unit sequence respectively to generate two units. image. In the case of starting the N interval start mode 322, the unit image module 41 receives and processes all the output signals output by the ultrasonic probe 802 by each unit sequence to generate (N+1) unit images.

Step (6) synthesize the unit images to produce a complete ultrasound image. The image synthesizing module 42 superimposes the unit images generated by the unit image module 41 to generate the complete ultrasonic image, and outputs the touch display 804 displayed on the host 801. Since there are many ways to superimpose and combine a plurality of images into a single image, and it is not an improvement focus of the present invention, it will not be described in detail.

Referring to Figures 1, 2, 4A, and 4B, when the ultrasonic wave unit 803 is activated and received by the conventional address-based sorting, the single ultrasonic unit 803 is connected to another adjacent address. The sound wave unit 803 interferes with the amplitude of the output signal generated by the ultrasonic signal (frequency: 1 MHz, peak-to-peak (PP) voltage 28.1 V). However, when the ultrasonic units 803 are activated by the parity start mode 321 at an address interval, the activated ultrasonic units 803 do not interfere with each other, so the output signal generated by the single ultrasonic unit 803 There is no drift (frequency: 1 MHz, peak-to-peak (PP) voltage value 32.8 V). Based on this, since the probe array image manipulation system and method of the present invention can indeed improve the signal interference problem caused by the driving method of the conventional ultrasonic probe 802, the image quality of the unit images generated in the present case is relatively improved, so it can be synthesized. Combine a better quality ultrasound image.

In summary, the ultrasound array probe 802 can control the ultrasonic probe 802 to sequentially start the design of the ultrasonic units 803 by means of at least one ultrasonic unit 803, which can improve the traditional sequential activation. The problem that the adjacent ultrasonic units 803 interfere with each other can greatly reduce the complexity of the back-end signal and image processing by directly improving the quality of the front-end output signal, and can effectively improve the imaging quality of the complete ultrasonic image. In addition, when the ultrasonic array unit 803 of the adjacent address is sequentially activated, the probe array controller 3 can stop the medical ultrasonic device 800 and issue an abnormal warning message to ensure the design. The entire medical ultrasound device 800 will no longer operate in the conventional ultrasound probe 802 start control mode. Therefore, the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
