The client application 112 can be an application that needs to be downloaded and installed before running or a small program (liteapp) as a lightweight application. In the case where the client application 112 is an application that needs to be downloaded and installed before running, the client application 112 can be pre-installed on the client device 110 and activated. In the case where the client application 112 is a small program, the user 102 can directly run the client application 112 on the client device 110 by searching for the client application 112 in the host application (for example, by the name of the client application 112, etc.) or scanning the graphic code of the client application 112 (for example, a bar code, a QR code, etc.), without installing the client application 112.

In some embodiments, the client device 110 may alternatively be a stationary computer device, such as a desktop computer, a server computer or other types of stationary computer devices. In some optional embodiments, the client device 110 may also be or include a medical image printing device.

[0022] The server 120 is typically a server deployed by an Internet Service Provider (ISP) or an Internet Content Provider (ICP). The server 120 may represent a single server, a cluster of multiple servers, a distributed system, or a cloud server that provides basic cloud services (such as cloud databases, cloud computing, cloud storage, and cloud communications). It will be understood that although Figure 1 The server 120 is shown in FIG. 1 as communicating with only one client device 110 , but the server 120 may provide background services for multiple client devices simultaneously.

[0025] The image acquisition device 140 may be connected to the client device 110 , for example, via the network 130 , or directly connected to the client device in other ways to communicate with the client device.

[0026] Optionally, the system may further include an intelligent computing device or computing card 150.

[0030] Figure 2 2 is a flowchart illustrating a medical image processing method 200 according to an exemplary embodiment. The method 200 may be performed on a client device (eg, Figure 1 The execution of each step of the method 200 may be performed at the client device 110 shown in FIG. Figure 1 In some embodiments, the method 200 may be performed on a server (e.g., Figure 1 In some embodiments, method 200 may be performed by a client device (eg, client device 110) and a server (eg, server 120) in combination.

[0031] In the following, each step of the method 200 is described in detail.

[0032] refer to Figure 2 At step 210, first scanning data is obtained, where the first scanning data is medical image scanning data of a target human body through a scanning probe.

[0033] At step 220, second scanning data is obtained, where the second scanning data is scanning data for an acoustic positioning unit located between the target human body and the scanning probe, and the acoustic positioning unit has an acoustic positioning pattern composed of at least two acoustic positioning points.

[0034] At step 230 , the first scan data is processed based on the second scan data and the acoustic positioning pattern to obtain three-dimensional reconstruction data about the target human body.

[0035] Through the above method, three-dimensional reconstruction data can be obtained with the help of acoustic positioning patterns.

[0036] The method according to the exemplary embodiment of the present disclosure can be applied to various scanning probes and various types of medical scan images. In particular, the method according to the exemplary embodiment of the present disclosure is applicable to scenarios that meet one or more of the following conditions: the probe does not contain a positioning device or there are not enough positioning devices inside the probe, the probe is operated by a person rather than by a mechanical or intelligent probe drive device, and it is difficult to obtain the position and rotation posture of the probe, etc. Ultrasound scanning is an example of a scanning scenario that meets these conditions. In view of these characteristics of ultrasound scanning, how to obtain three-dimensional image reconstruction without major modifications to the ultrasound probe itself has always been a difficult problem in this field. .

[0037] Taking an ultrasound probe as an example, according to an exemplary embodiment of the present disclosure, an auxiliary position marker can be added by introducing an acoustic positioning unit without changing the existing ultrasound probe. Thus, the position of the skin surface can be obtained when the probe moves, which is equivalent to providing registration information on the skin surface.

[0038] According to some embodiments, the acoustic positioning unit is a membrane-like unit that can cover the surface of human skin. Figure 3A As shown, an exemplary probe 301, an acoustic positioning unit 302 and a human body surface 303 are shown. It is understandable that, although it is represented as a "membrane unit" here, the acoustic positioning unit is not required to be a film shape or material commonly understood, nor is it required to be light-transmissive or transparent. It only needs to be much smaller in the height direction from the probe to the human body than in the length and width of the surface in the vertical height direction (e.g., the surface contacted by the probe). For example, the membrane unit may also be referred to as a patch unit, and the present disclosure is not limited thereto.

[0039] In some embodiments, the acoustic positioning unit may be a soft membrane that can be deformed according to the deformation of the human skin surface. In such an embodiment, the soft membrane can fit the human skin surface, so that the probe will not be displaced from the human skin surface during movement, thereby achieving a better positioning effect.

[0040] In some embodiments, the acoustic positioning unit may be a rigid membrane. Exemplarily, the acoustic positioning unit may have a curvature matching with the scanning probe on a side facing the scanning probe.

[0041] Exemplarily, the acoustic positioning unit may be a curved hard membrane for cooperating with an ultrasound probe.

[0042] like Figure 3B As shown, an exemplary probe 311, an acoustic positioning unit 312 and a human body surface 313 are shown, wherein the acoustic positioning unit has an arc shape. The arc shape of the acoustic positioning unit can be designed to make the skin surface deform as a whole when a force is applied, thereby reducing wrinkles on the skin surface. For example, the arc shape of the acoustic positioning unit can be designed to make the deformation of the skin surface as consistent as possible, for example, having an equal radius of curvature everywhere. This is very practical for scanning certain specific parts of the human body and tissues. For example, when detecting the breast, the use of an arc-shaped dura mater can reduce local deformation, so that the deformation of the skin surface is consistent when the probe is at different angles, thereby facilitating the reference of the position of the tissue, organ or lesion below the skin surface, and obtaining a more accurate three-dimensional reconstruction result.

[0043] According to one or more embodiments of the present disclosure, various coating liquids such as acoustic guiding liquid may be applied between two or three of the scanning probe, the acoustic positioning unit and the human body, thereby reducing gaps and obtaining better scanning effects.

[0044] The acoustic positioning unit may be mainly made of a material that has no or little influence on the acoustic reflection characteristics of the scanning probe, and has a plurality of acoustic positioning points that influence the acoustic characteristics distributed therein, so that positioning can be performed based on the acoustic positioning points.

[0045] For example, the acoustic positioning points can be arranged by filling with a material different from the main body of the acoustic positioning unit, hollowing out, or changing the density at the relative position. The acoustic positioning points can be designed into a specific position, shape or pattern. The pattern formed by the acoustic positioning points can be input into the algorithm to assist the algorithm in parsing the image, so as to realize the analysis of the probe position, posture, etc. through these points.

[0046] In some embodiments, the acoustic localization pattern may be distributed along a single layer of the membrane-like unit. Figure 3C As shown, an exemplary probe 321 and an acoustic positioning unit 322 are shown, and a plurality of acoustic positioning points are distributed in the acoustic positioning unit 322. In addition, a human body is shown below, such as tissue 323 or lesion 324 therein, and its morphology is only an example. During the scanning process, the scanning data corresponding to the tissue 323 or lesion 324 can be obtained as the first scanning data, and the corresponding scanning data of the acoustic positioning points distributed in the acoustic positioning unit 322 can be obtained as the second scanning data, so that the corresponding probe posture is obtained with the second scanning data as a reference, so as to obtain the acquisition posture, displacement, rotation angle, etc. corresponding to each corresponding first scanning data, and then obtain the three-dimensional reconstruction data.

[0047] In some other optional embodiments, the acoustic positioning pattern may be multi-layered. The multi-layered acoustic positioning pattern can provide more information for the reverse calculation of the rotation angle of the probe during the three-dimensional reconstruction process.

[0048] According to one or more embodiments of the present disclosure, for existing stock probes, without the need to improve the scanning probe, an acoustic positioning unit can be used as an accessory to obtain three-dimensional image reconstruction data based on existing probes for acquiring two-dimensional images.

[0049] In some embodiments, the acoustic positioning unit includes a plurality of regions, and each region is encoded by a pattern formed by acoustic positioning points in the region.

[0050] In some embodiments, encoding each region by a pattern formed by acoustic positioning points in the region includes encoding by at least one of the following items in the corresponding region: size, shape, position, and distribution of the acoustic positioning points.

[0051] Although the various operations are depicted in the drawings as being in a particular order, this should not be understood as requiring that these operations must be performed in the particular order shown or in a sequential order, nor should it be understood as requiring that all the operations shown must be performed to obtain the desired results. For example, two steps described in order herein may be performed in reverse order, or may be performed concurrently. For another example, one or more steps in the various embodiments of the present disclosure may be omitted.

[0052] In addition, it is understood that the method for predicting or determining data involved in one or more embodiments of the present disclosure is not a method for a doctor to directly determine the diagnosis result, but involves data processing or information processing in the medical process, and the data processing result can be used for reference by the doctor, thereby assisting the doctor's medical operation. It is understood that the information processing method, data prediction method, determination method, decision-making method, etc. involved in one or more embodiments of the present disclosure are executed by a computer or a device including a computer.

[0053] It is to be understood that throughout the present disclosure, an image or an image sequence may be or may include two-dimensional image data, or may be or include three-dimensional image data. An image or an image sequence may be image data that is directly acquired and stored or otherwise sent to a terminal device for use by a user. An image or an image sequence may also be processed image data after various image processing. An image or an image sequence may undergo other analysis processes (e.g., an analysis process for whether there are pathological features or lesions) and include analysis results (e.g., circling of an area of ​​interest, segmentation results of a tissue, etc.). It is to be understood that the present disclosure is not limited thereto.
