However, the existing ultrasonic endoscopes are all single-frame imaging when displaying ultrasonic images, so that ultrasonic endoscopes supporting different frequencies cannot simultaneously display synchronously acquired ultrasonic images with different frequencies on the same display interface, and therefore the ultrasonic images with different frequencies cannot be compared at the same time. In addition, when the ultrasonic images acquired by the ultrasonic endoscope are replayed, the ultrasonic endoscope images in a once scanning state can be seen, and a plurality of images cannot be compared at the same time. It can be understood that in actual clinical practice, since the existing ultrasonic endoscopes are all single-frame imaging, at most, only the mode of film playback can be used, the ultrasonic endoscope images in the once scanning state can be seen back, and the comparison of a plurality of images can not be performed simultaneously. The clinical staff can only review the last scanned image and cannot review the previous scanned image at the same time, so that correlation analysis is difficult to perform, and inconvenience is brought to the use of users.
In order to solve the above-mentioned problem, in the embodiment of the present application, a storage area and a display area are allocated for each acquisition frequency of the dual-frequency ultrasonic endoscope; when the acquisition mode of the double-frequency ultrasonic endoscope is double-frequency acquisition, storing ultrasonic data corresponding to each acquisition frequency in a corresponding storage area, and displaying an ultrasonic image generated based on each ultrasonic data in a corresponding display area; when the acquisition mode of the double-frequency ultrasonic endoscope is single-frequency acquisition, acquiring target acquisition frequency corresponding to the single-frequency acquisition, storing ultrasonic data corresponding to the target acquisition frequency in a corresponding storage area, and displaying an ultrasonic image generated based on the ultrasonic data corresponding to the target acquisition frequency on a display area.

The application will be further described by the description of embodiments with reference to the accompanying drawings.
The embodiment provides an ultrasonic image acquisition method based on a double-frequency ultrasonic endoscope, which is based on the double-frequency ultrasonic endoscope, wherein the double-frequency ultrasonic endoscope comprises an ultrasonic probe and a driver, the ultrasonic probe is used for carrying out ultrasonic scanning on biological tissues, the ultrasonic probe emits ultrasonic waves through an ultrasonic transducer to detect the biological tissues, and reflected signals of the biological tissues are received and converted into electric signals; the driver is used for driving the ultrasonic probe to move so as to realize 360-degree circular scanning. The ultrasonic probe comprises two groups of ultrasonic transducers, the working frequencies of the two groups of ultrasonic transducers can be different, for example, the working frequency of one group of ultrasonic transducers is 12MHz, and the working frequency of the other group of ultrasonic transducers is 20MHz.
As shown in fig. 1, the method for acquiring an ultrasound image based on a dual-frequency ultrasound endoscope provided in this embodiment specifically includes:
s10, distributing a storage area and a display area for each acquisition frequency of the double-frequency ultrasonic endoscope.
Specifically, the dual-frequency ultrasonic endoscope is configured with two acquisition frequencies, which are respectively marked as a first acquisition frequency and a second acquisition frequency, and is configured with two storage areas and two display areas, which are respectively marked as a display area 1, a display area 2, a storage area 1 and a storage area 2, wherein the storage area 1 and the storage area 2 respectively correspond to the two acquisition frequencies, and the display area 1 and the display area 2 are both used for displaying ultrasonic images. As shown in fig. 2, the dual-frequency ultrasound configures a storage area 1 for a first acquisition frequency and a storage area 2 for a second acquisition frequency, wherein the two storage areas are independent of each other, and the two display areas are independent of each other and are located on the same display interface. It can be understood that two display areas are allocated to the dual-frequency ultrasonic endoscope on the same display interface, and the two display areas are used for displaying ultrasonic images, wherein the two display areas can synchronously display ultrasonic images corresponding to the two acquisition frequencies respectively, one display area can display ultrasonic images acquired in real time at one acquisition frequency, the other display area can display ultrasonic images acquired in real time at the last acquisition frequency, one display area can display ultrasonic images acquired in real time at one acquisition frequency, and the other display area can display ultrasonic images acquired in last ultrasonic scan at the other acquisition frequency. In addition, corresponding acquisition parameters can be configured for each acquisition frequency in advance, the respective acquisition parameters can be stored in the storage area corresponding to each acquisition frequency, and when the respective ultrasonic image corresponding to each acquisition frequency is acquired, the respective acquisition parameters can be directly called from the storage area corresponding to each acquisition frequency to configure each acquisition frequency, wherein the acquisition parameters can comprise control frequency and imaging algorithm
In one implementation, each display region may be configured with a display parameter, where the display parameter is used to reflect an operational state of the display region. The display parameters include a frozen state and a thawed state, wherein the frozen state reflects that the display area is in a selected display of the ultrasound image, i.e., an image selected by a frame of the ultrasound image is displayed, and the thawed state reflects that the display area is in a real-time display of the ultrasound image. Thus, the display state of each display area can be set by setting the display parameters of the display area, wherein the display parameters of the display area are set to be in a defrosting state, the display area is used for displaying the ultrasound image acquired in real time, and when the display parameters of the display area are set to be in a freezing state, the display area is used for displaying the ultrasound image acquired last time or the ultrasound image which needs to be frozen. For example, as shown in fig. 3, the display parameter of the display area 1 is in a defrosted state, and the display parameter of the display area 2 is in a frozen state.
And S20, when the acquisition mode of the double-frequency ultrasonic endoscope is double-frequency acquisition, storing ultrasonic data corresponding to each acquisition frequency in a corresponding storage area, and displaying an ultrasonic image generated based on each ultrasonic data in a corresponding display area.
Specifically, the dual-frequency acquisition refers to synchronous real-time display of two ultrasonic images with different frequencies acquired by a dual-frequency ultrasonic endoscope, that is, two ultrasonic images with different ultrasonic frequencies acquired by the same acquisition time of the dual-frequency ultrasonic endoscope are synchronously displayed in various corresponding display areas. Thus, in the case of dual-frequency acquisition, after the ultrasound data corresponding to each acquisition frequency is stored in the respective storage region, an ultrasound image is generated based on each ultrasound data, and the generated ultrasound image is displayed in the respective display region. In practical application, the ultrasonic images corresponding to each acquisition frequency can be processed through different threads, so that the imaging processes of the two ultrasonic images are parallel, on one hand, the generation speed of the ultrasonic images can be improved, on the other hand, the synchronism of the ultrasonic images can be ensured, the ultrasonic images with different ultrasonic frequencies can be synchronously displayed on the same display interface at the same acquisition time, and a user can simultaneously know the ultrasonic images with two different ultrasonic frequencies.
For example, as shown in fig. 4, the dual-frequency ultrasonic endoscope is configured with a 12MHz ultrasonic transducer and a 20MHz ultrasonic transducer, then after ultrasonic data is acquired by the 12MHz ultrasonic transducer and the 20MHz ultrasonic transducer, ultrasonic data a of the 12MHz ultrasonic transducer is stored in its corresponding storage area 1 and ultrasonic data B of the 20MHz ultrasonic transducer is stored in its corresponding storage area 2, then ultrasonic images C are generated based on the ultrasonic data a, ultrasonic images D are generated based on the ultrasonic data B, the ultrasonic images C are displayed in a display area 1 corresponding to the 12MHz ultrasonic transducer, and the ultrasonic images D are displayed in a display area 2 corresponding to the 20MHz ultrasonic transducer, respectively.
In one implementation, when the acquisition mode is a dual-frequency mode, the two display areas are required to display the ultrasound image simultaneously, so that the display parameters of the two display areas need to be set to a thawing state. Thus, when the acquisition mode is dual-frequency acquisition, the method further includes, before storing the ultrasound data corresponding to each acquisition frequency in the respective corresponding storage region:
the display parameters of the respective display areas are set to a thawing state.
Specifically, when the acquisition mode is determined to be dual-frequency acquisition, parameters of each display area are acquired, and the display parameters in the display areas are modified to be in a frozen state and are modified to be in a unfreezing state. It can be appreciated that in the working process of the dual-frequency ultrasonic endoscope, the acquisition mode of the dual-frequency ultrasonic endoscope can be switched, i.e. the single-frequency acquisition mode can be switched to the dual-frequency acquisition mode. And when the single-frequency acquisition mode is switched to the double-frequency acquisition mode, modifying the display parameters in the display area into a frozen state into a unfreezing state. Of course, in practical application, when both display areas are in a frozen state, it is necessary to set the display parameters of both display areas to a defrosted state.
In one implementation, due to the different positions of the two groups of ultrasonic transducers in the dual-frequency ultrasonic endoscope, time deviation exists in data swept out in a 360-degree loop, so that angle deviation exists between ultrasonic images formed based on ultrasonic data acquired by the two groups of ultrasonic transducers. Based on this, the displaying the ultrasound image generated based on each ultrasound data on the respective corresponding display region specifically includes:
generating ultrasonic images based on the ultrasonic data, and performing angle registration on the generated ultrasonic images to obtain ultrasonic images after the angle registration;
and displaying the ultrasonic images after the angle registration in the display areas corresponding to the ultrasonic images.
In particular, the angular registration is used to adjust the orientation of the image content in each ultrasound image so that the orientation of the image content in the two images matches. The angular registration may be performed by a feature point matching manner, that is, when configuring the ultrasound images, a plurality of image feature points corresponding to each ultrasound image may be obtained, where each ultrasound image is respectively denoted as a first ultrasound image and a second ultrasound image for convenience of explanation. Accordingly, the process of angular registration may be:
respectively acquiring a plurality of image feature points of a first ultrasonic image and a second ultrasonic image;
and performing angle registration on the first ultrasonic image and the second ultrasonic image based on the acquired image feature points to obtain each ultrasonic image after the angle registration.
Specifically, the image feature points of the first ultrasonic image and the second ultrasonic image may be obtained by a feature point extraction model trained in advance, or may be extracted by a conventional feature point extraction method, or the like.
After the image feature points are obtained, a plurality of image feature points in the first ultrasonic image and a plurality of image feature points in the second ultrasonic image can be matched to obtain matching feature point pairs, so that error feature points can be removed by matching the image feature points, and the accuracy of angle registration of candidates based on the image feature images is improved. After the feature point pair is obtained, the first ultrasonic image reference image is used for carrying out geometric transformation on the second ultrasonic image based on the position information of the feature point in the feature point pair, so that the position error of the feature point in the feature point pair is smaller than a preset threshold value, and the first ultrasonic image and the second ultrasonic image after the angle registration are obtained. Of course, in practical application, the second ultrasound image may be used as a reference image, and the geometric transformation may be performed on the first ultrasound image.
S30, when the acquisition mode of the double-frequency ultrasonic endoscope is single-frequency acquisition, acquiring target acquisition frequency corresponding to the single-frequency acquisition, storing ultrasonic data corresponding to the target acquisition frequency in a corresponding storage area, and displaying an ultrasonic image generated based on the ultrasonic data corresponding to the target acquisition frequency on a display area.
Specifically, the single-frequency acquisition refers to that one display area displays an ultrasonic image acquired in real time in the current ultrasonic scanning in two display areas of the display interface, and the other display area displays an ultrasonic image determined in the previous or previous scanning or is in an idle state. Thus, as shown in fig. 5, in the single-frequency acquisition mode, the target acquisition frequency adopted in the single-frequency acquisition mode needs to be acquired, then an ultrasonic image corresponding to the target acquisition frequency is displayed in one display area, and the other display area displays an ultrasonic image determined by one or any previous scanning, or is in an idle state, or displays other ultrasonic images needing to be frozen. In the single-frequency acquisition, the ultrasonic transduction group corresponding to the other acquisition frequency except the target acquisition frequency can be in a dormant state, i.e. the ultrasonic transduction group does not acquire ultrasonic data.
In addition, in practical application, in order to facilitate review of the ultrasound image acquired by each acquisition frequency, when the dual-frequency ultrasound endoscope performs single-frequency acquisition, the ultrasound transducer group corresponding to another acquisition frequency except the target acquisition frequency may also perform ultrasound data acquisition, that is, when ultrasound data is acquired by synchronization of the two acquisition frequencies, the ultrasound data of each acquisition frequency is stored in a storage area corresponding to each acquisition frequency, and an ultrasound image is generated only based on the ultrasound data corresponding to the target acquisition frequency. Therefore, the display of the ultrasonic image corresponding to the target acquisition frequency is ensured, the ultrasonic image corresponding to the other acquisition frequency can be played back, the ultrasonic data can be acquired through single-frequency acquisition, double-frequency playback can be performed, and convenience is brought to users.
In one implementation manner, when the acquisition mode of the dual-frequency ultrasonic endoscope is single-frequency acquisition, the display parameter of one display area is in a thawing state, and the display parameter of the other display area is in a freezing state 。
Specifically, when the acquisition mode is single-frequency acquisition, the display area in the defrosting state is a display area for displaying the acquired ultrasonic image, and in the ultrasonic scanning process, the display area is in the defrosting state for displaying the ultrasonic image in real time, and the other display area is in the freezing state for displaying the ultrasonic image selected by a certain frame. It is understood that the display parameter of the display area displaying the acquired ultrasound image is set to the thawing state and the display parameter of the other display area is set to the freezing state. In addition, when the acquisition mode is single-frequency acquisition, when the display parameter of one display area is in a defrosting state, the display parameter of the other display area can be automatically set in a freezing state, so that the setting of the two display areas can be completed through one operation, and the setting steps of the display parameters are reduced. For example, the display area 1 displays an ultrasound image acquired at the current time corresponding to 12MHz, and the display area 2 displays an ultrasound image acquired at one time in one scanning process of 20 MHz; or, the display area 1 displays an ultrasonic image acquired at the current moment corresponding to 12MHz, the display area 2 displays an ultrasonic image acquired at one moment in a scanning process of 12MHz, or the display area 1 displays an ultrasonic image acquired at the current moment corresponding to 20MHz, and the display area 2 is in an idle state or the like.
After the ultrasonic image generated based on the ultrasonic data corresponding to the target acquisition frequency is displayed on a display area, whether the current scanning process is finished is detected, when the scanning process is not finished, the display area used for displaying the ultrasonic image generated by the ultrasonic data corresponding to the target acquisition frequency is kept in a thawing state, and the other display area is kept in a freezing state, so that an operator can display the ultrasonic image obtained by one scanning on the same display area, and the ultrasonic image acquired by one ultrasonic scanning is displayed in a consistent manner on a display interface, thereby bringing convenience to a user. For example, the display area 1 displays each ultrasound image acquired by the first scan, and the display area 2 is in an idle state. In addition, after the scanning process is finished, the display parameters of the display areas can be kept unchanged, the display parameters of the display areas in the unfreezing state can be set to be in the frozen state, and the display parameters of the display areas in the frozen state can be set to be in the unfreezing state, so that the two display areas alternately display the ultrasonic images scanned by the scanning processes.
Further, in the single-frequency acquisition mode, the single-frequency acquisition mode can be switched to the double-frequency acquisition mode, and at the moment, the display parameters of the two display areas are directly set to be in a defrosting state. Therefore, the display parameters of the display areas can be switched between a defrosting state and a freezing state according to the acquisition mode of the dual-frequency ultrasonic endoscope, in other words, the acquisition mode of the dual-frequency ultrasonic endoscope can be switched in the scanning process, and the display parameters of the display areas are switched on the basis of the switched acquisition mode, so that the display parameter configuration of the display areas is matched with the acquisition mode of the dual-frequency ultrasonic endoscope. In the process of using the double-frequency ultrasonic endoscope, an operator can freely switch the acquisition mode of the double-frequency ultrasonic endoscope according to actual needs so as to realize different display states, for example, the real-time display of the ultrasonic image with only one acquisition frequency, or the synchronous real-time display of the ultrasonic images with two acquisition frequencies, and the like.
In this embodiment, the ultrasound data corresponding to the two acquisition frequencies are stored in the respective corresponding storage spaces, so that after the ultrasound scanning is performed, the ultrasound image can be played back based on the ultrasound data stored in the respective storage spaces. Thus, in one implementation, as shown in fig. 7 and 8, the method further comprises:
when a playback instruction is acquired, acquiring a playback mode corresponding to the playback instruction;
when the playback mode is double-frequency playback, extracting ultrasonic data from each storage area, and displaying an ultrasonic image generated based on the extracted ultrasonic data on each display area;
and when the playback mode is single-frequency playback, acquiring playback acquisition frequency corresponding to the single-frequency playback, extracting ultrasonic data from a storage area corresponding to the playback acquisition frequency, and displaying an ultrasonic image generated based on the extracted ultrasonic data on a display area.
Specifically, the playback mode includes dual-frequency playback and single-frequency playback, wherein dual-frequency playback refers to synchronous playback of ultrasonic images of two acquisition frequencies, single-frequency playback may be real-time playback of an ultrasonic image of one acquisition frequency, or alternatively playback of corresponding ultrasonic images of two acquisition frequencies, wherein when an ultrasonic image of one acquisition frequency is played back in real time, two display areas alternately display a real-time playback image corresponding to the acquisition frequency, while a previous playback image is frozen, the corresponding ultrasonic image of the two acquisition frequencies is played back in real time for one of the two display areas, the other display area displays a previous playback image of the other acquisition frequency, and the ultrasonic images corresponding to the two acquisition frequencies are alternately in a real-time playback state. Therefore, during dual-frequency playback, ultrasonic data are synchronously extracted from each storage area, the ultrasonic data which are synchronously extracted are processed to generate ultrasonic images, and the ultrasonic images are displayed in the corresponding display areas, wherein when the ultrasonic data are synchronously extracted from the storage areas, time stamps can be used as extraction basis, and the time stamps corresponding to the ultrasonic data extracted from each storage area are the same each time, so that the ultrasonic images which are acquired at the same acquisition frequency and the same acquisition time can be synchronously played back in the corresponding display areas, and the playback comparison of the ultrasonic images at the same acquisition time is convenient.
Further, during single-frequency playback, the playback acquisition frequency corresponding to the single-frequency playback is acquired, ultrasonic data is extracted from the storage area corresponding to the playback acquisition frequency, an ultrasonic image generated based on the extracted ultrasonic data is displayed on one display area, the other display area is in a frozen state, the playback image corresponding to the previous playback time is displayed, so that the two display areas display the ultrasonic images at different acquisition times, and an operator can conveniently compare the ultrasonic images at different acquisition times.
In addition, it should be noted that the playback mode may be freely switched during the playback process, for example, the dual-frequency playback mode is switched to the single-frequency playback mode, the playback acquisition frequency corresponding to the single-frequency playback mode is switched, the single-frequency playback mode is switched to the dual-frequency playback mode, and the like. The processing procedure of the playback mode switching is the same as the processing procedure of the mode switching in the acquisition process, and will not be described herein, specifically, reference may be made to the above description.
