It will be understood that, although... Figure 1 The diagram shows that server 120 communicates with only one client device 110, but server 120 can provide background services to multiple client devices simultaneously.

[0020] System 100 may further include image acquisition device 140. In some embodiments, Figure 1 The image acquisition device 140 shown may be a medical scanning device, including but not limited to scanning or imaging devices used in positron emission tomography (PET), positron emission tomography with computerized tomography (PET / CT), single photon emission computed tomography with computerized tomography (SPECT / CT), computed tomography (CT), medical ultrasonography, nuclear magnetic resonance imaging (NMRI), magnetic resonance imaging (MRI), cardiovascular angiography (CA), digital radiography (DR), etc. For example, image acquisition device 140 may include digital subtraction angiography scanner, magnetic resonance angiography scanner, computed tomography angiography scanner, positron emission tomography scanner, positron emission tomography (PET) scanner, single photon emission computed tomography (SPT) scanner, computed tomography scanner, medical ultrasound examination equipment, magnetic resonance imaging (MRI) scanner, digital radiography scanner, etc. Image acquisition device 140 may be connected to a server (e.g., Figure 1 The system connects to server 120 (or a separate server of the imaging system, not shown in the figure) to process image data, including but not limited to converting scan data (e.g., converting it into a medical image sequence), compressing it, correcting pixels, and reconstructing it in three dimensions.

[0021] Image acquisition device 140 may be connected to client device 110, for example, via network 130, or otherwise directly connected to client device to communicate with client device.

[0022] Optionally, the system may also include an intelligent computing device or a computing card 150. The image acquisition device 140 may include or be connected (e.g., detachably connected) to such a computing card 150. As an example, the computing card 150 can perform image data processing, including but not limited to conversion, compression, pixel correction, reconstruction, etc. As another example, the computing card 150 can implement a method for ultrasound scanning according to embodiments of the present disclosure.

[0023] The system may also include other components not shown, such as a data storage unit. The data storage unit may be a database, data repository, or other form of device for data storage; it may be a conventional database, or it may include a cloud database, a distributed database, etc. For example, direct image data generated by the image acquisition device 140, or medical image sequences or three-dimensional image data obtained through image processing, may be stored in the data storage unit for subsequent retrieval by the server 120 and client device 110. Furthermore, the image acquisition device 140 may also directly provide direct image data or medical image sequences or three-dimensional image data obtained through image processing to the server 120 or client device 110, etc.

[0026] Figure 2 This is a flowchart illustrating a method 200 for ultrasound scanning according to an exemplary embodiment. Method 200 can be performed on a client device (e.g., Figure 1 The execution is performed at the client device 110 shown, that is, the execution entity of each step of method 200 can be... Figure 1 The client device 110 shown. In some embodiments, method 200 can be performed on a server (e.g., Figure 1 The method 200 is executed at server 120 (as shown in the figure). In some embodiments, the method 200 may be executed in combination by a client device (e.g., client device 110) and a server (e.g., server 120).

[0027] The steps of method 200 are described in detail below.

[0028] refer to Figure 2 In step 210, the ultrasonic transceiver unit of the ultrasonic probe is controlled to rotate relative to the housing of the ultrasonic probe.

[0029] At step 220, scan data is obtained, which is obtained by transmitting and receiving ultrasonic signals at at least two different rotation angle positions through the ultrasonic transceiver unit during the rotational motion process.

[0030] In step 230, the rotation angle information of the ultrasonic transceiver unit corresponding to the scan data is obtained.

[0031] In step 240, an ultrasound image of the target area is obtained based on the scan data and the rotation angle information.

[0032] The above method enables high-precision ultrasound scanning.

[0033] For example, by controlling the rotation of the ultrasonic transceiver unit inside the housing, a large-scale scan of the target area can be achieved while the probe remains externally stationary. This method obtains a uniform and repeatable scan path, thereby ensuring the regularity and integrity of the spatial distribution of the scan data and providing a precise data foundation for subsequent high-quality imaging.

[0034] According to some embodiments, the method may further include establishing a mapping relationship between the rotation angle information and the ultrasound signal. In such embodiments, the ultrasound image of the target region may be constructed based on the mapping relationship and the scan data. According to such embodiments, by establishing an accurate mapping relationship, one-dimensional time-series ultrasound signals can be accurately reconstructed into a two-dimensional or three-dimensional spatial coordinate system, thereby achieving precision and accuracy in ultrasound scan results.

[0035] It is understood that the rotational motion can be a circular motion around the central axis of the probe, or a reciprocating oscillation within a specific angular range. It is understood that the rotation angle information can be obtained through feedback from the motor controller, an internal angle sensor, or an encoder, and this disclosure is not limited thereto.

[0036] It is understood, and further elaborated below in conjunction with other embodiments, that the ultrasonic probe to which the method of this disclosure can be applied may include a housing and a rotatable ultrasonic transceiver unit disposed within the housing. According to some additional embodiments, the ultrasonic probe may include a sound-conducting medium located between the contact surface of the ultrasonic transceiver unit and the housing.

[0037] According to some exemplary embodiments, controlling the rotational movement of the ultrasonic transceiver unit relative to the housing of the ultrasonic probe is achieved using a stepper motor.

[0038] According to this embodiment, precise digital control of the rotation angle can be achieved. For example, the rotation angle of each stepper motor can be fixed, thus the system can directly determine the current rotation position by calculating the number of pulses sent to the motor, without the need for an additional angle sensor. This simplifies the internal hardware structure of the probe, reducing cost and size.

[0039] According to some embodiments of this disclosure, it is possible to flexibly switch between a stepping mode, for example, for high-precision static acquisition, and a continuous rotation mode, for example, for rapid dynamic scanning, by controlling the pulse frequency. Exemplarily, the method may include driving the ultrasonic transceiver unit to perform at least one of stepping rotation or continuous rotation. It is understood that stepping rotation may refer to the motor rotating a fixed step angle, pausing data acquisition, and then rotating to the next step. It is understood that continuous rotation may refer to the motor rotating continuously at a smooth or relatively smooth speed, during which the ultrasonic unit acquires data. It is understood that the drive motor may be connected to the ultrasonic transceiver unit via gears, belts, or direct coupling, and this disclosure is not limited thereto.

[0040] Furthermore, it is understood that, as will be described below in conjunction with certain specific non-limiting embodiments, the speed of the rotational motion can be constant or dynamically varied according to scanning requirements. For example, the rotational speed can be reduced within certain specific angular ranges to increase sampling density, while the speed can be increased within other angular ranges to shorten scanning time.

[0041] Understandably, the process of constructing ultrasound images can be completed in the processor inside the ultrasound probe, or the data can be transmitted to an external computing device (such as a tablet or workstation) for processing.

[0042] According to some embodiments, obtaining an ultrasound image of a target region may include constructing a three-dimensional reconstructed image of the target region based on the spatial extent covered by the rotational motion.

[0043] Through such embodiments, cylindrical or sector-shaped volume data generated by rotational scanning can be used to achieve enhanced spatial depth and connectivity information, thereby more completely displaying the morphology, volume, and three-dimensional positional relationship of lesions with surrounding blood vessels or tissues, providing more intuitive and comprehensive spatial anatomical information for clinical diagnosis.

[0044] According to some embodiments, the method may further include adjusting the transmission frequency of the ultrasonic transceiver unit during its rotation. This enables richer and more precise ultrasonic scanning.

[0045] According to some embodiments, the scanning data may include ultrasonic echo data acquired at the same target location in the target region but using different transmission frequencies.

[0046] For example, the method may include controlling the ultrasound transceiver unit to acquire ultrasound echo data of the same target location at different transmission frequencies under different rotation cycles or different rotation angles. In such an embodiment, the response characteristics of a target location, such as a target tissue, at different ultrasound frequencies can be acquired. Since tissues of different depths and different types of lesions have different absorption, scattering, and reflection characteristics for ultrasound waves of different frequencies, by acquiring multi-band data, it is possible to combine the deep penetration advantage of low-frequency ultrasound with the high resolution advantage of high-frequency ultrasound, or to utilize frequency difference information to mine the acoustic fingerprint of tissues, thereby significantly enriching the amount of diagnostic information contained in the scan.

[0047] Those skilled in the art will understand that adjusting the transmission frequency can be achieved by changing the frequency of the electrical signal that excites the ultrasonic transducer. For example, the ultrasonic transducer can be a broadband transducer, supporting operation in a range of, for example, 1 MHz to 10 MHz or wider. Multi-frequency data for the same target location can mean that the same voxel or pixel in space has echo intensity values ​​corresponding to multiple dimensions such as frequency A and frequency B.

[0048] In some additional embodiments, frequency adjustment can be a continuous frequency sweep or discrete frequency transitions. For example, the system can first perform a coarse full-depth scan using a lower frequency, and then perform a fine scan of the shallow region using a higher frequency. Alternatively, pulses of different frequencies can be alternately emitted in a single scan sequence. It is understood that the above are merely examples, and this disclosure is not limited thereto.

[0049] In some embodiments, the constructed ultrasound image may include ultrasound spectrum information for at least one pixel based on ultrasound echo data acquired using different transmission frequencies.

[0050] According to this embodiment, traditional anatomical imaging can be upgraded to functional spectral imaging. By analyzing the energy distribution or attenuation characteristics of specific pixels in the frequency domain (i.e., spectral information), microscopic structural features of tissues that are difficult to distinguish with the naked eye can be revealed. This spectral information can serve as a novel quantitative biomarker to help identify pathological states of tissues, such as distinguishing between benign and malignant tumors, or identifying the degree of fibrosis in tissues.

[0051] Understandably, ultrasound spectral information can be represented as a normalized power spectrum, a curve showing the backscattering coefficient as a function of frequency, or a spectral parameter plot (such as spectral slope and spectral intercept). In an image, this can be presented as a "spectral parameter plot" or "pseudo-color image" superimposed on an anatomical diagram, where different colors represent different spectral characteristic values.

[0052] Additionally and / or alternatively, the system may allow the user to select a point of interest on an image and display a detailed frequency response curve for that point in a sidebar. In some other embodiments, this spectral information may be input into subsequent classification algorithms to assist in the automated qualitative analysis of tissues. It is understood that the above are merely examples and this disclosure is not limited thereto.

[0053] In some embodiments, adjusting the transmission frequency of the ultrasonic transceiver unit may include controlling the ultrasonic transceiver unit to switch the transmission frequency once after each rotation cycle during the scanning process targeting the same target location.

[0054] This embodiment ensures that each complete set of 3D or 2D image data is acquired under a single, stable frequency condition, thereby guaranteeing data consistency within a single scan cycle. This time-division multiplexing frequency scanning strategy allows the system to sequentially acquire multiple complete volumetric data points from different frequency perspectives, facilitating subsequent hierarchical multi-frequency image fusion processing. It also simplifies the scanning control logic and avoids transient interference caused by frequent frequency switching. For example, the probe can first complete a 360-degree rotation scan at 5MHz to establish the first layer of data; then adjust to 7.5MHz and perform another 360-degree rotation scan to establish the second layer of data. In this way, for each location in space, layered data corresponding to different frequencies are ultimately accumulated.

[0055] In some additional embodiments, if the probe comprises multiple array elements, frequency A may be used for some elements and frequency B may be used for others during a single rotation. Alternatively, frequency A may be used for the first half of a rotation and frequency B for the second half. It is understood that the above are merely examples and this disclosure is not limited thereto.

[0056] In some embodiments, adjusting the transmission frequency of the ultrasonic transceiver unit may include controlling the ultrasonic transceiver unit to rotate a predetermined number of times at different transmission frequencies within a predetermined time period, so that ultrasonic signals of multiple different frequency bands for a target area can be obtained within the predetermined time period.

[0057] According to this embodiment, it is possible to rapidly acquire wide-frequency domain tissue information within a short time window. Through high-frequency rotation and rapid frequency switching, the system can capture the dynamic changes in tissues or complete multi-dimensional spectral data acquisition in a very short time, making it particularly suitable for scenarios requiring rapid screening or real-time dynamic monitoring.

[0058] Understandably, the "predetermined time period" can be one second or several seconds. For example, the ultrasonic transceiver unit can be controlled to rotate at a frequency of tens of times per second, acquiring multiple ultrasonic signals of different frequency bands within each second to obtain a wide-range frequency response curve. Another example is controlling a stepper motor to run at 10 revolutions per second, with the first three revolutions using 3MHz, the middle three using 5MHz, and the last four using 8MHz within the first second. This completes multi-band coverage of the target area within one second. This method fully utilizes the high frame rate characteristics of rotating scanning.

[0059] According to some embodiments, the method may further include: in response to determining that a region of interest exists in the target region, adjusting the operating mode or scanning parameters of the ultrasound transceiver unit to perform a targeted scan of the region of interest.

[0060] This embodiment enables intelligent and adaptive control of the scanning process. Instead of blindly performing uniform scanning, the system proactively changes its strategy based on initially detected anomalies (regions of interest), concentrating resources to probe key areas. This mechanism not only improves the detection rate and diagnostic accuracy of lesions but also optimizes performance by reducing detailed scanning of irrelevant areas, thereby lowering system power consumption and data processing load.

[0061] For example, the method may include identifying whether a region of interest exists within the target region based on currently acquired scan data. For example, the method may determine the existence of a region of interest based on user instructions. Those skilled in the art will understand that a region of interest (ROI) can be an area in an image exhibiting abnormal echoes (such as hyperechoic nodules or hypoechoic areas) or an area conforming to specific anatomical features (such as vascular cross-sections). The identification process can be automatically completed by built-in computer-aided detection (CAD) algorithms or artificial intelligence (AI) models, or it can be responsive to a doctor's identification, such as a selection operation on a touchscreen or other actions.

[0062] According to some embodiments, adjusting the operating mode or scanning parameters of the ultrasonic transceiver unit includes adjusting the rotation speed of the ultrasonic transceiver unit.

[0063] According to some embodiments, adjusting the operating mode or scanning parameters of the ultrasound transceiver unit includes adjusting the frequency range by limiting the ultrasound transmission frequency to a corresponding frequency band for scanning based on the tissue characteristics of the region of interest.

[0064] For example, the ultrasound emission frequency can be limited to a specific sensitive frequency band for scanning based on the tissue characteristics of the region of interest. According to such an embodiment, image contrast and detail representation of the region of interest can be maximized. Different lesions (such as cysts, calcifications, and fibromas) often exhibit optimal imaging results at specific frequency bands. By focusing on this sensitive frequency band for targeted scanning, interference from irrelevant frequency bands can be avoided, highlighting the characteristic information of the lesion and thus assisting doctors in making more accurate qualitative judgments.

[0065] According to some embodiments, adjusting the operating mode or scanning parameters of the ultrasonic transceiver unit includes adjusting the emission intensity to enhance the ultrasonic emission intensity for the region of interest.

[0066] According to this embodiment, the signal-to-noise ratio of key areas can be locally improved while ensuring that the overall acoustic energy output meets safety standards. By directionally enhancing the emission intensity of the region of interest, the echo signal in that region can be made clearer. Especially for small lesions with weak echoes or located deep within the body, this enhancement can significantly improve their visibility and increase the usability and accuracy of ultrasound scan results.

[0067] According to some embodiments, adjusting the operating mode or scanning parameters of the ultrasound transceiver unit includes adjusting the imaging mode by at least one of the following: switching to an elastography mode, or adjusting the waveform mode to avoid interference from specific tissue boundaries.

[0068] This embodiment provides a multimodal diagnostic perspective and anti-interference capability. Switching to elastography mode can reveal tissue stiffness information, which is of great value in differentiating between benign and malignant tumors; while adjusting the waveform mode (such as changing the beam shape or pulse phase) can effectively deal with reflection artifacts or occlusions caused by complex acoustic interfaces (such as blood vessel walls and bone surfaces), thus obtaining clear and accurate lesion features even in complex environments.

[0069] According to some embodiments, adjusting the operating mode or scanning parameters of the ultrasound transceiver unit also includes achieving spatial differential scanning by: controlling the ultrasound transceiver unit to generate a preset sampling position offset relative to the position of the previous scan in subsequent rotational scans targeting the region of interest; and using the data difference generated by the sampling position offset to improve the imaging resolution of the region of interest.

[0070] According to this embodiment, super-resolution imaging can be achieved using sub-pixel-level micro-displacements. By artificially introducing minute positional shifts or offsets between multiple scans, and using these subtly different data for differential operations or reconstruction, the inherent physical resolution limitations of the hardware can be overcome, revealing finer tissue textures and edge information. This offers significant technical advantages for observing minute calcifications or early microlesions.

[0071] For example, the sampling position offset can be achieved by controlling the stepper motor to take microsteps, such as sampling at 0°, 1°, and 2° in the first scan, and sampling at 0.5°, 1.5°, and 2.5° in the second scan. For example, data differential processing can be performed using a super-resolution reconstruction algorithm, such as fusing subpixel displacement information between multiple low-resolution images to create a single high-resolution image.

[0072] In some embodiments, the ultrasound probe can be fixed to the surface of the subject's body via a wearable structure. In such embodiments, the method may include automatically switching from a static scanning mode to a rotational scanning mode during monitoring.

[0073] This embodiment combines the convenience of long-term monitoring with the professionalism of accurate diagnosis. In static scanning mode, the system can maintain basic monitoring functions with low power consumption; once an anomaly is detected or a predetermined trigger condition is met, it automatically switches to a high-precision rotating scanning mode to obtain detailed three-dimensional data. This mechanism not only significantly reduces the average power consumption of the device and extends the usage time of the wearable device, but also enables intelligent capture and diagnosis in unattended situations.

[0074] Those skilled in the art will understand that the wearable structure can be an elastic strap, an adhesive patch, or a flexible buckle device. A static scanning mode can refer to the ultrasound unit remaining stationary, performing only low-frequency detection along a single line or plane; while a rotational scanning mode can include activating a motor to perform a full-range volumetric scan. The trigger condition for automatic switching can be AI identifying suspicious echo changes, or it can be a timed trigger, and this disclosure is not limited to these.

[0075] According to some additional and / or alternative embodiments of this disclosure, the method may include acquiring image data from an ultrasound unit of an ultrasound probe; driving an ultrasound unit located inside the ultrasound probe to rotate relative to a contact surface of the ultrasound probe; acquiring a plurality of scan data frames from the ultrasound unit during the rotation; acquiring angular position information of the ultrasound unit when acquiring the scan data frames; and obtaining a three-dimensional reconstruction result of a target region based on the scan data frames and the angular position information.

[0076] According to some additional and / or alternative embodiments of this disclosure, the method may include controlling an ultrasonic unit within an ultrasonic probe to perform a rotational scan along a preset motion trajectory, wherein the ultrasonic unit is immersed in a sound-conducting liquid; during the rotational scan, adjusting the emission frequency of the ultrasonic unit so that it detects at different center frequencies within different rotation cycles; acquiring the echo signals of the ultrasonic unit at different rotation angles and different center frequencies, establishing a mapping relationship between each spatial sampling point and the ultrasonic frequency response, and generating ultrasonic spectrum data of the target area.

[0077] It is understood that the steps and features of these additional / alternative embodiments according to this disclosure can be applied to suitable methods according to other embodiments of this disclosure, such as those referenced. Figure 2 The method described herein, or its variations thereof, will not be elaborated upon here.

[0078] The following is combined with Figure 3 Some non-limiting embodiments according to this disclosure are described. For example... Figure 3 As shown, the provided ultrasonic probe may include a housing (not shown), a controllable rotation ultrasonic unit (i.e., ultrasonic transceiver unit) disposed within the housing, and a sound-conducting medium located outside the ultrasonic unit (shown in the figure as "acoustic coupling fluid", which may also be referred to as a coating fluid or coupling fluid).

[0079] Specifically, the bottom of the ultrasound probe may have a contact surface (not shown) that conforms to the skin surface of the object being tested (e.g., human body). Figure 3 The image also shows a matching layer located at the contact surface for matching. The controllable rotation ultrasound unit can be immersed in the sound-conducting medium or acoustically coupled to the contact surface through the sound-conducting medium. Thus, when the ultrasound unit rotates, the contact surface of the probe can remain stationary and in close contact with the skin surface, while also facilitating the implementation of a fixed structure for long-term wear, such as a strap or patch.

[0080] For example, the probe may also include a drive mechanism, such as a stepper motor (not shown) as described above. The stepper motor may be mechanically connected (e.g., bundled together) to the controllable rotation ultrasound unit to drive the ultrasound unit to rotate relative to the probe housing. Because the stepper motor has precise step angle control capabilities, the system can accurately know how many revolutions the stepper motor has made and its current angular position, thereby establishing a precise mapping relationship between the physical rotation angle and the ultrasound image data.

[0081] According to another embodiment of this disclosure, a scanning method based on the aforementioned probe is provided. In addition to conventional ultrasonic sector scanning, embodiments of this disclosure support rotational scanning to obtain three-dimensional structural information of a target region (as shown in the figure, the subcutaneous lesion region). The method may include driving an ultrasound unit to rotate 360 ​​degrees or within a specific angular range. During rotation, the ultrasound unit emits ultrasound waves at a predetermined frequency and receives echoes. The system determines the rotation angle information of the ultrasound unit based on feedback from a stepper motor, and combines this angle information with acquired A-mode or B-mode ultrasound data to construct a three-dimensional image of the subcutaneous tissue using a three-dimensional reconstruction algorithm (such as cylindrical coordinate system reconstruction).

[0082] According to another embodiment of this disclosure, a multi-frequency scanning-based "ultrasound spectrum" imaging technique is provided. Because different human tissues (such as fat, muscle, and diseased tissue) exhibit different frequency response characteristics (frequency response curves) to ultrasound waves of different frequencies, a single-frequency scan may miss important information. In such an example, the emission frequency of the ultrasound unit can be configured to be adjustable within a certain range (e.g., between 1 MHz and 10 MHz). During rotational scanning, the system controls the ultrasound unit to perform multiple scans on the same spatial location (or the same pixel / voxel), with each scan using a different center frequency. For example, the ultrasound unit switches emission frequencies every time it rotates; or the frequency is switched rapidly during rotation. Assuming the system rotates or emits at a frequency of tens of times per second, dozens of echo data from different frequency bands can be acquired per second. By integrating this data, the system can generate a corresponding "ultrasound spectrum" for each pixel in the image. This greatly increases the amount of information detected, allowing doctors or AI algorithms not only to see the morphology of tissues but also to analyze their acoustic response characteristics to different frequencies, thereby more accurately diagnosing lesions.

[0083] According to another embodiment of this disclosure, an adaptive scanning mode based on a region of interest (ROI) is provided. In such an embodiment, the scanning mode is not static but adaptively adjusted based on the discovered content. This process can be manually triggered by a physician or automatically triggered by a built-in artificial intelligence (AI) module of the system.

[0084] For example, the process may include an initial / global scan, such as first performing a wide-area scan in a default mode (e.g., standard frequency, standard rotation speed). Next, the process may include identifying regions of interest (ROIs), for example, through AI image recognition algorithms or by a physician identifying suspected lesion areas in the scanned images (e.g., "subcutaneous lesion area" in the figure). Afterward, parameter optimization and targeted scanning may be included, for example, adjusting the operating parameters of the ultrasound unit after determining the ROI to optimize imaging of that area.

[0085] As previously described, the adjustment methods include, but are not limited to, frequency optimization, spatial differential and super-resolution, and energy and mode adjustment.

[0086] Frequency optimization can also be called spectral focusing. As a specific, non-limiting example, assuming the initial scan range is 1MHz-10MHz, if the lesion is found to have the most obvious echo characteristics or the highest contrast in the 5MHz-8MHz frequency band, the system can limit the subsequent scanning frequency to this range and perform finer-grained frequency step scans to obtain more refined spectral characteristics.

[0087] Spatial difference and super-resolution refer to the process of controlling a stepper motor to create minute positional shifts during consecutive rotation cycles in order to visualize minute lesions or improve accuracy and precision. For example, the first scan angle might be 0°, 1°, 2°..., and the second scan angle might be adjusted to 0.5°, 1.5°, 2.5°... By differentially processing or fusing these two sets of slightly different data, the spatial resolution of the image can be significantly improved.

[0088] Energy and mode adjustments can be used to increase the emission intensity for specific lesions (such as blood vessel walls or deep nodules) or switch to elastography mode to avoid interference from surrounding tissues or obtain information on tissue stiffness.

[0089] According to another embodiment of this disclosure, a wearable monitoring application is provided. In such an embodiment, the ultrasound probe can be designed as a wearable device (e.g., integrated into a strap or patch). During routine monitoring, the device operates in a low-power or static scanning mode. When the AI ​​algorithm detects an abnormality through preliminary waveform analysis (e.g., subcutaneous bleeding, foreign body growth, or specific hemodynamic changes), or when a user / doctor issues a command, the stepper motor can be activated to switch from static mode to rotational scanning mode. In rotational mode, if dynamic information (such as blood flow velocity) is required, the stepper motor speed can be increased; if high-precision static anatomical structures are required, the system can reduce the speed and increase the sampling density. This provides medical-grade on-demand diagnostic capabilities while ensuring long battery life.

[0090] Although the various operations are depicted in the accompanying drawings in a specific order, this should not be construed as requiring that these operations must be performed in the specific order shown or in chronological order, nor should it be construed as requiring that all the operations shown must be performed to obtain the desired result. For example, two steps described in order herein may be performed in reverse order or may be performed concurrently. As another example, one or more steps in the various embodiments of this disclosure may be omitted.

[0091] Furthermore, it is understood that the methods for predicting or determining data according to one or more embodiments of this disclosure are not methods for doctors to directly determine diagnostic results, but rather involve data processing or information processing processes during the medical process. The data processing results can be used for doctors' reference, thereby assisting doctors in their medical operations. It is understood that the information processing methods, data prediction methods, determination methods, decision-making methods, etc., according to one or more embodiments of this disclosure are executed by a computer or a device containing a computer.

Images or image sequences may undergo other analysis processes (e.g., analysis of the presence of lesion features or lesions) and include analysis results (e.g., delineation of regions of interest, tissue segmentation results, etc.). It is understood that this disclosure is not limited thereto.
