Description

Technical Field

[0001] The present application relates to the field of medical imaging technology, and in particular to an ultrasonic scanning method and an ultrasonic system. Background Art

[0002] The scanning range of the whole breast scanning probe is relatively wide (about 15 cm in length). The probe travels about 15 cm under the traction of the mechanical device, and needs to scan a rectangular area of ​​15 cm*15 cm. Conventional scanning methods have a low frame rate, and generally require 1 minute to check a complete section, which takes a long time. Current high frame rate imaging technologies mainly include multi-line transmission (MLT) technology and plane wave technology.

[0003] The definition of MLT technology is that multiple transmitting apertures transmit ultrasound waves (generally focused waves) in different directions, and beam synthesis is performed based on echo data to obtain receiving scan lines in different directions. If two sets of ultrasound waves are transmitted at the same time, the frame rate will be increased by 1 times; plane wave imaging technology refers to the ultrasound transducer emitting unfocused ultrasound waves in a certain direction, and beam synthesis receiving scan lines within a wider range, thereby significantly improving the frame rate.

[0004] The existing MLT method has the following shortcomings: (1) the multiple groups of receiving beams generated by multiple transmitting beams interfere with each other, resulting in reduced image quality; (2) the transmitting scanning strategy is relatively limited and cannot meet flexible scanning requirements.

[0005] Existing plane wave method: The disadvantage is that if a complete plane wave is used, the number of channels is equal to the number of array elements, and the cost increases significantly; the plane wave technology implemented with smaller channels cannot avoid a large number of angle compounding. Compared with the complete plane wave, the frame rate is greatly reduced, and each angle requires a lot of beam synthesis operations, which is very computationally intensive, difficult to implement, and has no advantages.

Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0105] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0106] In one embodiment, the array includes array elements, a transmitting circuit and a receiving circuit, a processor and a display. The array elements are used to convert electrical signals into ultrasonic waves for transmission and to convert received ultrasonic echoes into electrical signals to obtain echo data. The array elements can be arranged in a linear array, such as Figure 2 , 3 As shown; it can also be arranged as a convex array, such as Figure 4 and Figure 5 shown.

[0107] The transmitting circuit is used to control the array element to transmit ultrasound to the subject. In an embodiment of the present invention, the transmitting circuit can control the first transmitting aperture and the second transmitting aperture on the array element to simultaneously transmit the first ultrasound and the second ultrasound to the first scanning area and the second scanning area in the subject.

[0108] The receiving circuit is used to control the array element to receive ultrasonic echoes and obtain echo data. In an embodiment of the present invention, the receiving circuit can control the first receiving aperture in the array element to receive ultrasonic echoes returned from the first scanning area to obtain first ultrasonic echo data, and control the second receiving aperture in the array element to receive ultrasonic echoes returned from the second scanning area to obtain second ultrasonic echo data. When receiving ultrasonic echoes, by controlling the time when the array element in the corresponding receiving aperture starts and stops receiving ultrasonic echoes, ultrasonic echoes from a predetermined area can be selectively received, thereby obtaining echo signals from the area. In this article, the area corresponding to the ultrasonic echo received by the aforementioned first receiving aperture is called the first scanning area, and the corresponding ultrasonic echo data is the first ultrasonic echo data; the area corresponding to the ultrasonic echo received by the aforementioned second receiving aperture is called the second scanning area, and the corresponding ultrasonic echo data is the second ultrasonic echo data.

[0109] The processor may obtain an ultrasound image based on the ultrasound echo data. For example, the processor may obtain a first ultrasound image of the subject based on the first ultrasound echo data, and obtain a second ultrasound image of the subject based on the second ultrasound echo data. The display may display the first ultrasound image and the second ultrasound image, respectively.

[0110] In one embodiment, the same transmitting circuit can control the first transmitting aperture and the second transmitting aperture to simultaneously transmit the first ultrasonic wave and the second ultrasonic wave to the first scanning area and the second scanning area in the body of the subject, or two different transmitting circuits can control the first transmitting aperture and the second transmitting aperture to simultaneously transmit the first ultrasonic wave and the second ultrasonic wave to the first scanning area and the second scanning area in the body of the subject. Similarly, the same receiving circuit can control the first receiving aperture and the second receiving aperture to respectively receive the echo of the first ultrasonic wave and the second ultrasonic wave, or two different receiving circuits can control the first receiving aperture and the second receiving aperture to respectively receive the echo of the first ultrasonic wave and the second ultrasonic wave. The first ultrasonic wave and the second ultrasonic wave are simultaneously transmitted and received independently of each other, and the first ultrasonic wave and the second ultrasonic wave can be transmitted non-parallel or in parallel.

[0111] The transmitted ultrasonic wave usually propagates in the whole field area. That is, the first ultrasonic wave may propagate to the second scanning area, and the second ultrasonic wave may propagate to the first scanning area. That is, the first ultrasonic echo signal from the first scanning area received through the first receiving aperture may contain an echo signal generated by the second ultrasonic wave being reflected by the tissue in the first scanning area in addition to the echo signal generated by the first ultrasonic wave being reflected by the tissue in the first scanning area. Similarly, the second ultrasonic echo signal from the second scanning area received through the second receiving aperture may contain an echo signal generated by the first ultrasonic wave being reflected by the tissue in the second scanning area in addition to the echo signal generated by the second ultrasonic wave being reflected by the tissue in the second scanning area. That is to say, the first ultrasonic wave and the second ultrasonic wave may affect each other's imaging. Therefore, in one embodiment of the present invention, the ratio of the echo signal strength of the first ultrasonic wave in the first scanning area to the echo signal strength of the second ultrasonic wave in the first scanning area is controlled to be not less than the first threshold value, and / or the ratio of the echo signal strength of the second ultrasonic wave in the second scanning area to the echo signal strength of the first ultrasonic wave in the second scanning area is controlled to be not less than the first threshold value. When this condition is met, it is considered that the first ultrasonic wave and the second ultrasonic wave have little influence on each other, and the imaging requirements of the first ultrasonic wave and the second ultrasonic wave are met.

[0112] For example, in one embodiment, before normal scanning imaging is performed, imaging parameters that meet the condition can be predetermined (e.g., the transmit aperture of the first ultrasonic wave and the second ultrasonic wave, the transmit aperture spacing of the first ultrasonic wave and the second ultrasonic wave, the frequency of the first ultrasonic wave and the second ultrasonic wave, the transmit power of the first ultrasonic wave and the second ultrasonic wave, the type of probe, etc.). For example, the first ultrasonic wave can be transmitted separately in advance to obtain the intensity of the echo signal of the first ultrasonic wave in the first scanning area, and then the transmission of the first ultrasonic wave is stopped and the second ultrasonic wave is transmitted separately to obtain the intensity of the echo signal of the second ultrasonic wave in the first scanning area, and then the ratio of the two is calculated, and the imaging parameters that make the ratio of the two meet the above requirements (e.g., not less than the first threshold) are confirmed as suitable imaging parameters; similarly, suitable imaging parameters corresponding to the second ultrasonic beam can be determined. Then, normal imaging scanning is performed with these confirmed suitable imaging parameters.

[0113] For example, Figure 1As shown, Tx1 and Tx2 are respectively the first transmitting circuit and the second transmitting circuit, Tx1 and Tx2 respectively control the transmission of the first ultrasonic wave and the second ultrasonic wave at the same time, Rx1 and Rx2 are respectively the first receiving circuit and the second receiving circuit, and Rx1 and Rx2 respectively control the reception of the first ultrasonic wave and the second ultrasonic wave. For the image point in the imaging area F1, the received signal strength from the first ultrasonic wave received by Rx1 is A11, and the received signal from the second ultrasonic wave received by Rx1 is A12. For the image point in the imaging area F1, when the ratio A11 / A12 of the echo signal strength of the first ultrasonic wave in the first scanning area to the echo signal strength of the second ultrasonic wave in the first scanning area is larger, it can be considered that the mutual influence between the first ultrasonic wave and the second ultrasonic wave is smaller. For example, in one embodiment, it can be considered that when the difference is not less than 100, the mutual influence between the first ultrasonic wave and the second ultrasonic wave is relatively small, and its influence on the imaging of the first ultrasonic wave and the second ultrasonic wave can be ignored or accepted. At this time, 100 is the first threshold. Similarly, for the image point in the imaging area 2, the received signal strength from the second ultrasonic wave received by Rx2 is A22, and the received signal strength from the first ultrasonic wave received by Rx2 is A21. The greater the ratio A22 / A21 of the echo signal strength of the second ultrasonic wave in the second scanning area to the echo signal strength of the first ultrasonic wave in the second scanning area, the smaller the mutual influence between the first ultrasonic wave and the second ultrasonic wave can be considered. For example, in one embodiment, it can be considered that when the difference is not less than 100, the mutual influence between the first ultrasonic wave and the second ultrasonic wave is relatively small, and its influence on the imaging of the first ultrasonic wave and the second ultrasonic wave can be ignored or acceptable. In one embodiment, the above two conditions can also be met at the same time, that is, A11 / A12 is not less than the first threshold and A22 / A21 is not less than the first threshold.

[0114] The specific value of the first threshold value can be determined according to the actual needs. For example, in one embodiment, the first threshold value can be a value not less than 30. If the requirement for the mutual influence of different ultrasonic waves is relatively low, the first threshold value can be 30. Similarly, if the requirement is relatively strict, the first threshold value can also be a value greater than 100, such as 316. The first threshold value can also be any value between 30 and 316, the first threshold value can also be a value greater than 316, and so on.

[0115] In the aforementioned embodiment, the first ultrasonic wave and the second ultrasonic wave are independently transmitted and received simultaneously, which greatly improves the scanning time and the frame rate. Moreover, the first ultrasonic wave and the second ultrasonic wave are independently received, and the beamforming calculation cost is also greatly reduced.

[0116] In one embodiment, the mutual influence of the first ultrasonic wave and the second ultrasonic wave during imaging can also be controlled by controlling the distance between the first transmitting aperture and the second transmitting aperture. For example, when the distance between the first transmitting aperture and the second transmitting aperture is large enough, it can be considered that the mutual influence of the first ultrasonic wave and the second ultrasonic wave is small enough or acceptable. Therefore, in this embodiment, the distance between the first transmitting aperture and the second transmitting aperture can be controlled to be not less than the second threshold. Here, the distance between the first transmitting aperture and the second transmitting aperture can be the distance between the midpoints of the two transmitting apertures, the distance between the array elements at the starting point of the two transmitting apertures, the distance between the array elements at the end point of the two transmitting apertures, or can be defined in other ways.

[0117] The specific value of the second threshold value can be determined according to the actual needs, as long as it can make the mutual influence between the first ultrasonic wave and the second ultrasonic wave on the imaging relatively small or acceptable. When the distance between the first transmitting aperture and the second transmitting aperture is greater than the second threshold value, the mutual influence between the transmission and reception of the first ultrasonic wave and the second ultrasonic wave will be smaller. The second threshold value may be related to the probe transmission waveform and the transmission angle. For example, in one embodiment, Figure 6 As shown, the first transmitting circuit Tx1 and the second transmitting circuit Tx2 in the breast probe simultaneously transmit the first ultrasonic wave and the second ultrasonic wave respectively, and both the first ultrasonic wave and the second ultrasonic wave are transmitted vertically (the sound beams are parallel to each other). If both Tx1 and Tx2 are grayscale imaging, and the transmitting waveforms are the same. At this time, after calculation (or measurement), it can be considered that when the transmission aperture spacing d between Tx1 and Tx2 is 5cm, the mutual influence between the two is acceptable.

[0118] In one embodiment, Tx1 is changed to contrast emission (waveform), and Tx2 is still grayscale image emission (waveform). Contrast is low-voltage emission, and the emission voltage of Tx1 may be 1 / 10 of that of Tx2. The emission waveforms of Tx1 and Tx2 are different. Therefore, the influence of Tx2 on Tx1 cannot be ignored. Therefore, under this condition, the spacing d of the emission aperture needs to continue to increase until the influence of Tx2 on Tx1 is relatively small or acceptable.

[0119] In one embodiment, the emission angle of the first ultrasonic wave and the second ultrasonic wave is between -180 degrees and 180 degrees, wherein when the angle is -180 degrees, the first ultrasonic wave and the second ultrasonic wave are emitted in a straight line towards each other, and when the angle is 180 degrees, the first ultrasonic wave and the second ultrasonic wave are emitted in a straight line towards each other. The angle may also be any angle between -180 degrees and 180 degrees.

[0120] In one embodiment, the emission angle between the first ultrasonic wave and the second ultrasonic wave is between -45 degrees and 45 degrees.

[0121] In one embodiment, the first ultrasonic wave and the second ultrasonic wave are emitted in parallel with each other, and the emission angle between the first ultrasonic wave and the second ultrasonic wave is 0 degrees. Figure 2 shown.

[0122] In one embodiment, the first ultrasonic wave and the second ultrasonic wave are simultaneously transmitted and received independently of each other, and the transmission parameters of the first ultrasonic wave and the second ultrasonic wave may be the same or different, wherein the transmission parameters include the frequency of the transmission waveform and / or the pulse repetition frequency and / or the transmission aperture and / or the transmission focus depth and / or the transmission power and / or the transmission mode. Figure 7 As shown, the first transmitting circuit Tx1 transmits a first ultrasonic wave, and the second transmitting circuit Tx2 transmits a second ultrasonic wave at the same time. The first ultrasonic wave and the second ultrasonic wave are transmitted and received independently of each other, and the first ultrasonic wave and the second ultrasonic wave detect different depths.

[0123] In one embodiment, the first ultrasonic wave and the second ultrasonic wave are simultaneously transmitted and received independently of each other, and the imaging modes used may be the same or different, wherein the imaging modes include B image imaging mode, Doppler image imaging mode, blood flow imaging mode or elastic imaging mode, for example, the first ultrasonic image and the second ultrasonic image may both be B images, or the first ultrasonic image may be a B image and the second ultrasonic image may be a C image. Figure 8 As shown, the first transmitting circuit Tx1 transmits a first ultrasonic wave, and the second transmitting circuit Tx2 transmits a second ultrasonic wave simultaneously, and the first ultrasonic wave and the second ultrasonic wave have different imaging modes.

[0124] In one embodiment, based on the above embodiment, the transmitting circuit can control the movement of the first transmitting aperture and the second transmitting aperture to scan the subject using the first ultrasonic wave and the second ultrasonic wave (for example, scanning from left to right or from right to left), and when the first transmitting aperture moves to the edge of the array element, the first ultrasonic wave is stopped from being transmitted through the first transmitting aperture, or when the second transmitting aperture moves to the edge of the array element, the second ultrasonic wave is stopped from being transmitted through the second transmitting aperture, such as Fig. 9 At the next moment, the second transmit aperture controlled by the second transmit circuit Tx2 is out of the probe range, and temporarily only the first transmit aperture controlled by the first transmit circuit Tx1 is transmitting. When the second transmit aperture starts from the left side of the array element and the distance from the first transmit aperture meets the independent transmission condition, the second transmit aperture starts transmitting from the left side of the probe.

[0125] In one embodiment, during normal imaging, the processor may also detect (for example, once at predetermined intervals) whether the ratio of the echo signal strength of the first ultrasonic wave in the first scanning area to the echo signal strength of the second ultrasonic wave in the first scanning area is not less than a first threshold, and stop transmitting the first ultrasonic wave through the first transmitting aperture or stop transmitting the second ultrasonic wave through the second transmitting aperture when the ratio of the echo signal strength of the first ultrasonic wave in the first scanning area to the echo signal strength of the second ultrasonic wave in the first scanning area is less than the first threshold; and / or the processor may detect whether the ratio of the echo signal strength of the second ultrasonic wave in the second scanning area to the echo signal strength of the first ultrasonic wave in the second scanning area is not less than the first threshold. For example, during a normal imaging scan, the processor may control the normal scan to be paused at regular intervals, and then transmit the first ultrasonic wave alone to obtain the intensity of the echo signal of the first ultrasonic wave in the first scanning area, and then stop transmitting the first ultrasonic wave and transmit the second ultrasonic wave alone to obtain the intensity of the echo signal of the second ultrasonic wave in the first scanning area, and then calculate the ratio of the two, and judge whether the ratio of the two is not less than the first threshold value; similarly, the processor may detect whether the ratio of the echo signal intensity of the second ultrasonic wave in the second scanning area to the echo signal intensity of the first ultrasonic wave in the second scanning area is not less than the first threshold value.

[0126] When the ratio of the echo signal strength of the second ultrasonic wave in the second scanning area to the echo signal strength of the first ultrasonic wave in the second scanning area is less than the first threshold, the processor can stop transmitting the first ultrasonic wave through the first transmitting aperture or stop transmitting the second ultrasonic wave through the second transmitting aperture. In this way, the processor can monitor the mutual influence between the first ultrasonic wave and the second ultrasonic wave, and automatically turn off one of the first ultrasonic wave and the second ultrasonic wave when the mutual influence between the two is too large, so as to avoid obtaining an ultrasonic image whose quality does not meet the requirements.

[0127] The processor may detect the first ultrasonic wave and the echo signal strength of the first ultrasonic wave in a suitable manner, for example, by turning off one and measuring the other, or may obtain the two signal strengths through simulation calculation.

[0128] In one embodiment, based on the above embodiment, the processor may also detect whether the distance between the first transmitting aperture and the second transmitting aperture is less than a second threshold, and when the distance between the first transmitting aperture and the second transmitting aperture is less than the second threshold, stop transmitting the first ultrasonic wave through the first transmitting aperture and / or stop transmitting the second ultrasonic wave through the second transmitting aperture. In this way, the processor can monitor the distance between the transmitting apertures of the first ultrasonic wave and the second ultrasonic wave, and automatically turn off one of the first ultrasonic wave and the second ultrasonic wave when the distance is too small, so as to avoid obtaining an ultrasonic image whose quality does not meet the requirements.

[0129] In the aforementioned embodiment, the processor obtains the first ultrasonic image and the second ultrasonic image according to the first ultrasonic echo signal and the second ultrasonic echo signal, respectively. In another embodiment, after obtaining the first ultrasonic echo signal and the second ultrasonic echo signal, the processor may also obtain an ultrasonic image of the subject according to both the first ultrasonic echo signal and the second ultrasonic echo signal. For example, the first ultrasonic wave can be used to scan a part of the subject, and the second ultrasonic wave can be used to scan another part of the subject, and the processor obtains an overall image of the subject including the part and the other part based on the echo signals of the two. In this way, by scanning a part of the subject with the first ultrasonic wave and the second ultrasonic wave respectively and combining the ultrasonic echo signals of the two to form an overall image, the frame rate of the final imaging of the subject can be greatly improved.
