SYSTEM AND METHOD FOR GENERATING ANATOMY-SPECIFIC INFORMATIONFIELD OF THE INVENTION
[0001] The present disclosure relates to the application of artificial intelligence (Al) in ultrasound imaging systems. Particularly, the present disclosure relates to a system and method for generating anatomy-specific information.BACKGROUND
[0002] The following description of related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art.
[0003] Accurate fetal assessment is crucial to ensure the healthy development of a fetus and detect any anomalies of the fetus. During each trimester, different anatomical structures are examined using ultrasound imaging, with standardized planes that provide detailed insights into fetal growth and potential anomalies. However, there are significant challenges in ensuring consistent and accurate diagnoses due to inter- and intra-operator variability. Sonologists rely heavily on their expertise to acquire the correct planes during ultrasound imaging.
[0004] Through years of practice, expert sonologists develop the ability to identify the presenting fetal anatomy, anticipate the next anatomical structure or plane, and determine the proper probe orientation to capture precise images. This process requires the sonologist to interpret complex factors, including the alignment of fetal and maternal anatomy, detailed knowledge of anatomical structures, and an understanding of fetal presentation and lie. A vast amount of information and experience is required to perform accurate scans, which, if not assimilated, can create inconsistencies in imaging quality, often leading to diagnostic errors. Furthermore, the shortage of skilled sonologists presents agrowing problem, leading to delayed access contributing to poor patient outcome.
[0005] Therefore, there is a need for a system and method which eliminates the variability caused by operator dependence, ensuring that every scan is performed with the same level of precision and thoroughness, regardless of skill level of the operator.SUMMARY

[0026] Figure 1 illustrates an environment 100 for establishing a system 102 for generating anatomy-specific information of an abdomen surface, in accordance with an embodiment of the present disclosure. The environment 100 may include an actuation unit 104, a stereo view vision unit 106, and an ultrasound transducer 108. In an embodiment, the stereo view vision unit 104 may include a dual lens camera unit configured to reconstruct a surface of a subject. The actuation unit 104 may be an electromechanical unit which includes a series of electrically actuated motors placed in a combination of series and parallel connections. The series of electrically actuated motors may be rotatory' or prismatic.
[0027] A beam-forming component of the ultrasound transducer 108 may be connected to tire actuation unit 104 as an end effector for obtaining a plurality of ultrasound image frames (herein thereafter referred to as ultrasound image frames). Tire actuation unit 104 may be an electronic head mount device, which guides a user holding the beam-forming component of the ultrasound transducer 108 in an augmented reality (AR) space for obtaining the ultrasound image frames. The user may include, but is not limited to, a sonographer, a nurse, a technician, a patient, and the like. The actuation unit 104 may be configured to use an adaptive hybrid force and position controller methodology7to compensate respiratory motion of the subject.
[0028] In an embodiment, the system 102 may be implemented within the actuation unit 104. In another embodiment, the system 102 may be externally connected to the actuation unit 104. Yet, in another embodiment, some part of the system 102 may be implemented within the actuation unit 104 and remaining part of the system 102 may be externally connected to the actuation unit 104. The system 102 may be a central server or hub for information extracted from a first global scout scan model, a second global scout scan model, and a third global scoutscan model. The first global scout scan model may include a neural network-based featureextraction model. The third global scout scan model may include a virtual anatomical model.
[0029] In an embodiment, the user may login to access the system 102 with a face identity’, or use credential information such as username or password. Once the face identity is recognized, the system 102 creates a unique identity registered with a face based on a user input. Once the face identity’ matches with the previous database or history’, the system 102 creates a new event or visit under the ID and assigns the ID to the user.
[0030] Further, the subject registration (Name, Date of Birth (DOB), and Last Menstrual Period (LMP)), which may be performed by the user either manually or by using an interactive voice command interface. Maternal history' of the subject may further be entered manually or through the interactive voice command. The maternal history of the subject may include, but is not limited to, age, weight, height, blood group, and the like. For a new visit, previous history' may be loaded, and latest reports may’ be fed into the system 102. Alternatively, the latest reports may be scanned through an electronic device and directly transferred to the system 102. The electronic device may include, but is not limited to, a mobile phone, a user device, a laptop, a tablet, and the like. Furthermore, the subj ect may be positioned under field of view of the stereo view vision unit 106. A user interface may’ be shown to cover the complete abdomen region of the subject.
[0031] In an embodiment, the system 102 may be configured to receive a first abdomen surface image of the subject from the stereo view vision unit 106. The stereo view vision unit 106 may include an image sensor, a Light Detection and Ranging (LIDAR) sensor, and an Infrared (IR) sensor. The first abdomen surface image may include, but is not limited to, an abdomen surface image of the subject, a reconstructed abdomen surface image of the subject, and the like. Further, the system 102 may be configured to determine a movement of the subject based on the received first abdomen surface image. For example, the stereo view vision unit 106 is configured to continuously monitor movement of the subject using a plurality of visual clues and automatically adjust if considerable movement is detected. If the movement of the subject is not observed, then the stereo view vision unit 106 transmits the first abdomen surface image to the system 102. If the movement of the subject is observed, then the stereo view vision unit 106 adjusts the first abdomen surface image. In an embodiment, the adjusted abdomen surface image may be represented as a reconstructed abdomen surface image. Further, the system 102 may be configured to identify that the subject has fully moved out of the field of view. Upon identifying the subject fully moving out of the field of view, the system 102 may be configuredto receive a second abdomen surface image from the stereo view vision unit 106 . For example, the stereo view vision unit 106 initiates a digital surface reconstruction step if the subject has fully moved out of the field of view of the stereo view vision unit 106, followed by an update to a matrix ‘M’. If the movement of the subject is not observed, the actuation unit 104 may be enabled.
[0032] The system 102 may be configured to represent the first abdomen surface image and the second abdomen surface image in coordinates using an inherent coordinate transformation. The inherent coordinate transformation may be represented by the matrix ‘M’ with a dimension of 4x4. The system 102 may include a feature extractor and detection network, a spatial image stacking network, and a feedback-based reinforcement learning decision-making system.
[0033] The system 102 may include a computational logic configured to determine landmarks (3D positions and orientations), which are overlaid on the first abdomen surface image or the second abdomen surface image. The landmarks may be sequenced and spread over the first abdomen surface image or the second abdomen surface image. Further, the landmarks may be transformed to self-actuation coordinates using the matrix ‘M’. In an embodiment, the system 102 may be configured to segment an abdomen region of the subject using contour and image based methods. The contour and image based methods may include structure from motion and simultaneous location and mapping methods. The abdomen region of the subject may be a region of the interest and generate the segmented region of the interest as point cloud data and continuous smooth surface as mesh. Hie 3D digital coordinates may be transferred to the actuation unit 104 from the stereo view vision unit 106.
[0034] Further, the system 102 may be configured to determine a spatial pose of the ultrasound transducer 108 associated with the actuation unit 104 relative to at least a portion of an abdomen surface to obtain the ultrasound image frames based on the received first abdomen surface image or the second abdomen surface. The spatial pose may refer to a three-dimensional position and orientation of the ultrasound transducer 108. In an embodiment, the system 102 may be configured to determine anatomy-specific landmarks of the first abdomen surface image or the second abdomen surface image for the actuation unit 104. Further, the system 102 may be configured to determine the spatial pose of the ultrasound transducer 108 based on the determined anatomy-specific landmarks.
[0035] Furthermore, the system 102 may be configured to determine one or more fetus-specific hotspot regions using the virtual anatomical model based on the obtained plurality of ultrasound image frames. The one or more fetus-specific hotspot regions may include, but are not limitedto, one or more fetal head regions, one or more fetal hand regions, one or more fetal thorax regions, one or more fetal abdomen regions, one or more fetal leg regions, and the like. The system 102 may be configured to extract a sequence of multi -model information and estimate the one or more fetus-specific hotspot regions of fetal anatomies across digitally reconstructed abdominal surface. Based on aforementioned analysis, the system 102 may be configured to determine where specific anatomical structures such as the fetal head, hands, or abdomen are likely located within a global coordinate frame derived from the first abdomen surface image or second abdomen surface image. The system 102 may be configured to combine extracted visual features, spatially arranged ultrasound image frames, and the virtual anatomical model. For example, the system 102 interprets the positioning of the fetus. Using the positioning of the fetus, the sy stem 102 predicts the approximate anatomical regions of interest and uses that information to guide subsequent scanning actions carried out by the actuation unit 104.
[0036] The virtual anatomical model may be a computational 3D avatar of a fetus. The virtual anatomical model may serve as a central geometric and visual reference that links the ultrasound image frames. In addition, the system 102 may be configured to generate the anatomy-specific information based on the determined one or more fetus-specific hotspot regions. The system 102 has been further detailed with reference to Figure 2 to Figure 8.

For example, the stereo view vision unit 106 continuously monitors the movement of the subject using the plurality of visual clues, and automatically adjust if considerable movement is detected. The system 102 may initiate the digital surface reconstruction step if the subject has fully moved out of the field of view of the stereo view vision unit 106, followed by an update to matrix ‘M’ throughout a workflow. If the movement of the subject is not observed, the actuation unit 104 may be enabled.
[0050] In an embodiment, the fetus-specific hotspot region determining module 306 may be configured to generate a spatial arrangement of the ultrasound image frames by stacking the ultrasound image frames together based on the received ultrasound image frames.
