[0002] Technical Field The present disclosure relates to real-time AI for physical biopsy marker detection. [Background technology]

[0003] During a breast biopsy, a physical biopsy site marker may be placed in one or more of a patient's breasts.

[Diagram 2] 1 shows an overview of an exemplary image processing system implementing real-time AI for physical biopsy marker detection as described herein.

[0012] Non-limiting and non-exhaustive examples are described with reference to the accompanying drawings.

[0013] Medical imaging has become a widely used tool for identifying and diagnosing abnormalities inside the human body, such as cancer or other conditions. Medical imaging procedures such as mammography and tomosynthesis are particularly useful tools for imaging the breast to screen or diagnose cancer or other lesions within the breast. A tomosynthesis system is a mammography system that allows high-resolution breast imaging based on limited angle tomosynthesis. Tomosynthesis generally produces multiple x-ray images that are discrete layers or slices of the breast throughout its thickness. In contrast to conventional two-dimensional (2D) mammography systems, tomosynthesis systems acquire a series of x-ray projection images, each acquired at a different angular displacement as the x-ray source moves along an arc-like path on the breast. In contrast to conventional computed tomography (CT), tomosynthesis is typically based on projection images acquired at limited angular displacements of the x-ray source around the breast. Tomosynthesis reduces or eliminates problems caused by tissue overlap and structural noise present in 2D mammography imaging. Ultrasound imaging is another particularly useful tool for imaging the breast. In contrast to 2D mammography images, breast CT, and breast tomosynthesis, breast ultrasound imaging does not deliver harmful X-ray radiation doses to the patient. Ultrasound imaging also allows manual, freehand, or automated scanning to collect 2D and 3D images and generate primary or supplemental breast tissue and lesion information.

[0014] In some instances, if an abnormality is identified within the breast, a breast biopsy may be performed. During a breast biopsy, a medical professional (e.g., a technician, radiologist, doctor, medical practitioner, surgeon, etc.) may place a biopsy site marker into the breast. If the breast histopathology of the breast containing the marker is subsequently determined to be malignant, the patient is often referred for a surgical course. During a surgical course consultation, the medical professional may attempt to confirm a previous diagnosis / recommendation by a prior medical professional. Confirmation may include attempting to locate the marker using an imaging device, such as an ultrasound machine. Often, the medical professional is unable to locate the placed marker for one or more reasons. For example, the placed marker may provide insufficient ultrasound visibility. As another example, the medical professional's ultrasound machine may be of insufficient quality to adequately detect and / or display the marker. As yet another example, the medical professional may not be skilled in reading ultrasound images. If the placed marker cannot be located by the medical professional, additional imaging may need to be performed or additional markers may need to be placed on the patient's breast. In both cases, the patient's user experience is severely and detrimentally affected.

[0015] In another example, a patient who has previously had a biopsy performed and had a marker placed may return for subsequent imaging, including subsequent screening and imaging under ultrasound. During subsequent screening, a medical professional may attempt to verify that a biopsy was performed on the previous abnormality. Verification may include attempting to locate the marker with an imaging device, such as an ultrasound machine. For reasons similar to those discussed above, a medical professional may not be able to locate the marker once it has been placed. As a result, additional imaging may be required or the patient may be scheduled for unnecessary surgery.

[0016] To address such issues with placed but undetectable markers, the present disclosure describes systems and methods for implementing real-time artificial intelligence (AI) for physical biopsy marker detection. In some aspects, a first set of characteristics for one or more biopsy site markers may be collected from various data sources. Exemplary data sources may include web services, databases, flat files, and the like. The first set of marker characteristics may include, but are not limited to, shape and / or size, texture, type, manufacturer, surface reflectance, reference number, material or composition characteristics, frequency signature, brand or model (or other marker identifier), and density and / or robustness characteristics. The first set of marker characteristics may be provided as input to an AI model. As used herein, an AI model may refer to a predictive or statistical utility or program that may be used to determine a probability distribution over one or more character sequences, classes, objects, outcome sets, or events, and / or to predict a response value from one or more predictors. The AI ​​model may be based on or incorporate one or more rule sets, machine learning, neural networks, reinforcement learning, etc. The first set of marker characteristics may be used to train the AI ​​model to identify patterns and objects, such as biopsy site markers, in one or more medical imaging procedures.

[0017] In some aspects, the trained AI model may receive a second set of marker characteristics associated with biopsy site markers placed / implanted in the patient's breast. The second set of marker characteristics may include or be related to one or more of the characteristics in the first set of characteristics (e.g., shape and / or size, texture, type, manufacturer, surface reflectance, reference number, material or composition characteristics, etc.). The second set of marker characteristics may include information not present in the first set of characteristics, such as new or non-functioning markers, optimal image data visualization, etc. The second set of marker characteristics may be received or collected from a data source, such as a medical professional's report or notes, patient records, or other hospital information system (HIS) data. The trained AI model may evaluate the second set of characteristics to determine a similarity or correlation between the second set of characteristics and the first set of characteristics. The evaluation may include, for example, identifying a marker shape, identifying or retrieving 2D / 3D images of the identified marker model or identification information, constructing a 3D image / model of the marker using the 2D image of the marker, generating an image of the marker placed in the environment, estimating the reflective properties of the marker and / or the environment (e.g., acoustic impedance, marker echogenicity, tissue echogenicity, etc.), identifying an estimated frequency range for the marker, etc. Based on the evaluation, the trained AI model may generate an output including the information identified / generated during the evaluation. In some aspects, at least a portion of the output may be provided to a user. For example, the trained AI model may access information regarding the biopsy procedure (e.g., biopsy date, radiologist name, implantation location, etc.) and / or the marker (e.g., shape, marker identifier, material, etc.). At least a portion of the accessed information may not be included in the second set of marker characteristics. Based on the accessed information, the trained AI model may output (or cause to be output) a comprehensive report including the accessed information.

[0018] In some aspects, after evaluating the second set of marker characteristics, an imaging device associated with the AI ​​model may be used to image the marker placement site for a marker corresponding to the second set of marker characteristics. Imaging the marker placement site may generate one or more images or videos and / or data associated with the imaging (e.g., imaging device settings, patient data, etc.). The images and data collected by the imaging device may be evaluated in real-time (while the imaging is being performed) by the AI ​​model. The evaluation may include comparing the images and data collected by the imaging device against an output generated by the AI ​​model related to the second set of marker characteristics. If the imaging device data and the AI ​​model output are determined to match, the location of the placed marker may be identified. In at least one aspect, the AI ​​model may not receive or evaluate the second set of marker characteristics prior to imaging the marker placement site with the imaging device. In such aspects, the AI ​​model may evaluate the images and data collected by the imaging device in real-time based on the first set of marker characteristics.

[0019] In some aspects, if a match is determined, the AI ​​model may generate one or more images of the placed marker. The one or more images may include an indication that the marker has been identified. Examples of indications may include highlighting or changing the color of the identified marker in the displayed image, playing an audio clip or alternative sound signal, displaying an arrow pointing to the identified marker, encircling the identified marker, providing a match confidence value, providing haptic feedback, etc. The image may further include supplemental information associated with the placed marker, such as the size or shape of the marker, the type or manufacturer of the marker, a marker detection confidence rating, and / or patient or procedure data. The supplemental information may be presented in the image, for example, using image overlay or content mixing techniques.

[0020] The present disclosure thus provides multiple technical advantages including, but not limited to, improving biopsy marker detection, analyzing medical images using real-time AI systems, improving echogenic object visibility based on object shape, generating 3D models of markers and / or environments containing markers, generating real-time displays of identified markers, and reducing the need for additional imaging and marker placement, among others.

[0021] FIG. 1 shows an overview of an exemplary system implementing real-time AI for physical biopsy marker detection as described herein. The exemplary system 100 as presented is a combination of multiple interdependent components that interact to form an integrated system for automating clinical workflow decisions. The components of the system may be hardware components (e.g., used to execute / run an operating system (OS)) or software components (e.g., applications, application programming interfaces (APIs), modules, virtual machines, runtime libraries, etc.) that are implemented (and / or executed) on the hardware components of the system. In one embodiment, the exemplary system 100 provides an environment for the software components to execute and may utilize the resources or facilities of the system 100 according to constraints set for operation. For example, the software may execute on a processing device such as a personal computer (PC), a mobile device (e.g., smart device, mobile phone, tablet, laptop, personal digital assistant (PDA), etc.), and / or any other electronic device. As an example of a processing device operating environment, reference is made to the exemplary operating environment shown in FIG. 4. In other embodiments, the components of the system disclosed herein may be distributed across multiple devices. For example, input may be entered at a client device and the information may be processed or accessed using other devices in the network, such as one or more server devices.

[0022] As an example, system 100 may include image processing system 102, one or more data sources 104, network 106, and image processing system 108. Those skilled in the art will recognize that a system such as system 100 may vary in size and may include more or fewer components than shown in FIG. 1. For example, in some embodiments, the functionality and components of image processing system 102 and one or more data sources 104 may be integrated into a single processing system. Alternatively, the functionality and components of image processing system 102 and / or image processing system 108 may be distributed across multiple systems and devices.

[0023] The image processing system 102 may be configured to provide imaging for one or more imaging modalities, such as ultrasound, CT, magnetic resonance imaging (MRI), x-ray, positron emission tomography (PET), etc. Examples of the image processing system 102 may include medical imaging systems / devices (e.g., x-ray devices, ultrasound devices, etc.), medical workstations (e.g., image capture workstations, image review workstations, etc.), etc. In some aspects, the image processing system 102 may receive or collect a first set of characteristics associated with one or more biopsy site markers from a first data source, such as one or more data sources 104. The first data source may represent one or more data sources and may be accessed over a network, such as the network 106. The first set of characteristics may include characteristics such as the shape, size, texture, type, manufacturer, reference number, material, composition, density, thickness, robustness, frequency signature, and reflectivity of the marker. In at least one embodiment, multiple sets of characteristics may be received or collected. In such an embodiment, each set of characteristics may correspond to a different portion or layer of the biopsy site marker. The one or more data sources 104 may include local and remote sources, such as web search utilities, web-based data repositories, local data repositories, flat files, and the like. In some embodiments, the data sources may further include data / knowledge provided manually by a user. For example, a user may manually input the biopsy site marker characteristics into the image processing system 102 by accessing a user interface. The image processing system 102 may provide the first set of characteristics to one or more AI models or algorithms (not shown) provided by (or accessible to) the image processing system 102. The first set of characteristics may be used to train the AI ​​model to detect the placed marker.

[0024] In some aspects, the image processing system 102 may receive or collect a second set of characteristics associated with the placed biopsy site marker. The biopsy site marker may be placed in the breast of a medical patient, for example, by a medical professional. The second set of characteristics may include, for example, one or more of the characteristics in the first set of characteristics and may be collected from a second data source. The second data source may represent one or more data sources and may be accessed over a network, such as the network 106. Examples of the second data source may include radiological reports, patient records, or other HIS data. The image processing system 102 may provide the second set of characteristics to a trained AI model. The trained AI model may evaluate the second set of characteristics to identify the shape, name, identifier, material, or composition of the biopsy site marker, or to construct one or more images of the biopsy site marker or the biopsy site marker environment from various angles and perspectives. Further, the trained AI model may estimate a resonant frequency value or a reflective characteristic of the biopsy site marker and / or the environment by evaluating the second set of characteristics. Based on the evaluation, the trained AI model may generate an output that includes the information identified / generated during the evaluation. For example, the output may be a data structure that includes a set of images representing various views of the biopsy site marker.

[0025] In some aspects, image processing system 102 may include hardware (not shown) for generating image data associated with one or more imaging modalities. The hardware may include an image analysis module configured to identify, collect, and / or analyze image data. For example, the hardware may be used to generate real-time patient image data associated with biopsy marker placement sites. In other aspects, image processing system 102 may be communicatively connected (or may be connectable) to an image analysis device / system, such as image processing system 108. The image analysis device / system may be internal or external to the image processing system 102 computing environment.

[0026] Image processing system 108 may be configured to provide imaging according to one or more imaging modalities as described with respect to image processing system 102. Image processing system 108 may comprise a trained AI model or may be configured to perform at least some of the functionality of a trained AI model. In some aspects, image processing system 108 may be internal or external to the computing environment of image processing system 102. For example, image processing system 102 and image processing system 108 may be co-located in the same healthcare environment (e.g., hospital, imaging center, surgery center, clinic, doctor's office). Alternatively, image processing system 102 and image processing system 108 may be provided in different computing environments. The different computing environments may or may not be located in separate geographic locations. When the different computing environments are in separate geographic locations, image processing system 102 and image processing system 108 may communicate via network 106. Examples of image processing system 108 may include at least the devices described with respect to image processing system 102. As an example, image processing system 108 may be a multimodal workstation connected to image processing system 102 and configured to generate real-time multimodal patient image data (e.g., ultrasound, CT, MRI, X-ray, PET). The multimodal workstation may be configured to perform real-time detection of placed biopsy site markers. Image data identified / collected by image processing system 102 may be transmitted or exported to image processing system 108 for analysis, presentation, or manipulation.

[0027] The hardware of image processing system 102 and / or image processing system 108 may be configured to communicate and / or interact with the trained AI model. For example, patient image data may be provided or made accessible to the trained AI model. Upon accessing the patient image data, the AI ​​system may evaluate the patient image data in real-time to facilitate detection of the placed marker. The evaluation may include using one or more matching algorithms and may provide visual, auditory, or tactile feedback. In some aspects, the described evaluation methods may enable medical personnel to quickly and accurately locate the placed marker while minimizing additional imaging of the placement site and placement of additional markers.

[0028] FIGURE 2 illustrates an overview of an exemplary image processing system 200 implementing real-time AI for physical biopsy marker detection as described herein. The biopsy marker detection techniques implemented by image processing system 200 may include at least some of the marker detection techniques and content described in FIGURE 1. In an alternative embodiment, a distributed system comprising multiple computing devices, each including components such as a processor and / or memory, may perform the techniques described in systems 100 and 200, respectively. With reference to FIGURE 2, image processing system 200 may include a user interface 202, an AI model 204, and imaging hardware 206.

[0029] The user interface 202 may be configured to receive and / or display data. In some aspects, the user interface 202 may receive data from one or more users or data sources. The data may be received as part of an automated process and / or as part of a manual process. For example, the user interface 202 may receive data from one or more data repositories in response to execution of a daily data transfer script, or an authorized user may manually input data into the user interface 202. The data may relate to one or more biopsy marker characteristics. Exemplary marker characteristics include identifier, shape, size, texture, type, manufacturer, reference number, material, composition, density, robustness, frequency signature, reflectivity, date of manufacture, quality rating, etc. The user interface 202 may provide functionality for viewing, manipulating, and / or storing the received data. For example, the user interface 202 may enable a user to group and sort the received data or compare the received data to previously received / past data. The user interface 202 may provide functionality for using the data to train an AI system or algorithm, such as the AI ​​model 204. The functionality may include load operations that process and / or provide the data as input to the AI ​​system or algorithm.

[0030] The AI ​​model 204 may be configured (or may be configurable) to detect the placed biopsy marker. In some aspects, the AI ​​model 204 may have access to data received by the user interface 202. Upon accessing the data, one or more training techniques may be used to apply the accessed data to the AI ​​model 204. Such training techniques are known to those skilled in the art. Applying the accessed data to the AI ​​model 204 may train the AI ​​model 204 to provide one or more outputs when one or more marker characteristics are provided as inputs. In some aspects, the trained AI model 204 may receive additional data via the user interface 22. The additional data may relate to characteristics of a particular biopsy marker. In some examples, the characteristics of a particular biopsy marker may be represented in the data used to train the AI ​​model 204. In such examples, the trained AI model 204 may generate one or more outputs using one or more characteristics of a particular biopsy marker. The output may include, for example, the shape of the particular biopsy marker, a 2D image of the particular biopsy marker, a 3D model of the particular biopsy marker, the reflectance properties of the particular biopsy marker, or the resonant frequency of the particular biopsy marker.

[0031] The imaging hardware 206 may be configured to collect image data of the patient. In some aspects, imaging hardware 206 may represent hardware for collecting one or more images and / or image data of a patient. Imaging hardware 206 may include an image analysis module configured to identify, collect, and / or analyze image data. Alternatively, imaging hardware 206 may be in communication with an image analyzer / system configured to identify, collect, and / or analyze image data. Imaging hardware 206 may transmit identified / collected image data to an image analyzer / system for analysis, presentation, and / or manipulation. Examples of imaging hardware 206 may include medical imaging probes, such as ultrasound probes, x-ray probes, and the like. Imaging hardware 206 may be used to determine the location of a biopsy marker placed on a patient. In some examples, imaging hardware 206 may generate real-time patient image data. The real-time patient image data may be provided to or made accessible to AI model 204. In some aspects, imaging hardware 206 may be further configured to provide an indication that a biopsy marker has been detected. For example, the imaging hardware 206 may include software that provides visual, audio, and / or tactile feedback to a user (e.g., a medical professional). When the AI ​​model 204 detects a biopsy marker during collection of image data by the imaging hardware 206, the AI ​​model 204 may send a command or set of instructions to the imaging hardware 206. The command / set of instructions may cause the hardware to provide visual, audio, and / or tactile feedback to the user. For example, a visual representation of the marker may be displayed to the user via an enhanced image. In the enhanced image, one or more aliasing techniques may be used to improve the visibility of the marker. For example, in the enhanced image, the marker may appear brighter or whiter, may appear a different color, or may appear to have its outline enhanced. Alternatively, the enhanced image may include a 2D or 3D symbol representing the marker. For example, a 3D representation of the marker may be displayed.The 3D representation may include the marker and / or the environment surrounding the marker. The 3D representation may be configured to be manipulated (e.g., rotated, tilted, zoomed in / out, etc.) by a user. In at least one embodiment, the visual display may include additional information associated with the marker, such as marker attributes (e.g., identifier, size, shape, manufacturer), marker detection confidence score or probability (e.g., indicating how closely the detected object matches a known marker), or patient data (e.g., patient identifier, marker implant date, surgery notes, etc.). The additional information may be presented in the augmented image, for example, using one or more image overlays or content mixing techniques.

[0032] Having described various systems that may be used in accordance with the disclosed aspects, the disclosure now describes one or more methods that may be performed in accordance with the various aspects of the disclosure. In some aspects, the method 300 may be performed by an exemplary system, such as the system 100 of FIG. 1 or the image processing system 200 of FIG. 2. In some embodiments, the method 300 may be performed in an apparatus that includes at least one processor configured to store and execute operations, programs, or instructions. However, the method 300 is not limited to such embodiments. In other embodiments, the method 300 may be performed in an application or service for implementing real-time AI for physical biopsy marker detection. In at least one embodiment, the method 300 may be performed (e.g., as a computer-implemented operation) by one or more components of a distributed network, such as a web service / distributed network service (e.g., a cloud service).

[0033] FIG. 3 illustrates an exemplary method 300 of implementing real-time AI for physical biopsy marker detection as described herein. The exemplary method 300 begins at operation 302, where a first data set including characteristics associated with one or more biopsy site markers is received. In some aspects, data associated with one or more biopsy site markers may be collected from one or more data sources, such as data source 104. The data may include marker identification information (e.g., product name, product identifier, or serial number, etc.), marker characteristic information (e.g., shape, size, material, texture, type, manufacturer, reflectance, reference number, composition, frequency signature, etc.), marker image data (e.g., one or more images of the marker), and supplemental marker information (e.g., manufacturing date, recalls or advisories, best or compatible imaging devices, etc.). For example, data associated with several biopsy site markers may be collected from various companies that manufacture and / or deploy the markers. The data may be aggregated and / or organized into a single data set. In some aspects, data may be collected automatically, manually, or some combination thereof. For example, a medical practitioner (e.g., a radiologist, surgeon or other physician, technician, medical practitioner, or anyone working under their direction) may access a marker application or service that has access to the marker data. The medical practitioner may manually identify and / or request a data set that includes marker data for a select group of marker providers. Alternatively, the marker application or service may automatically transmit the marker data to the medical practitioner (or its associated system / device) as part of a predefined schedule (e.g., following a nightly or weekly script).

[0034] In operation 304, the first data set is used to train an AI model. In some embodiments, the first data set collected from a data source may be provided to a data processing system, such as image processing system 200. The data processing system may include or have access to one or more machine learning models, such as AI model 204. The data processing system may provide the first data set to one of the machine learning models. Using the first data set, the machine learning model may be trained to correlate corresponding marker characteristic information to the marker identification information (and / or supplemental marker information, as described above). For example, the machine learning model may be trained to identify the shape of a marker based on the name of the marker, the identifier of the marker, or the label / indication of the shape of the marker (e.g., a "Q" marker may refer to a marker shaped similar to a "q"). In some embodiments, training the machine learning model may include retrieving or constructing one or more 2D images or 3D models of the marker. For example, the first data set may include a 2D image of the marker. Based on the 2D images, the machine learning model may construct additional 2D images of the marker from various viewpoints / angles using image construction techniques. The constructed 2D images may be used to construct a 3D model of the marker and / or a 3D model of the environment around the marker. The constructed image and model data may be stored by the machine learning model and / or the data processing system. In at least one embodiment, storing the image / model data may include adding the marker image / model data and corresponding marker identifiers to a data store (such as a database).

[0035] In operation 306, a second data set is received that includes characteristics associated with the biopsy site marker. In some aspects, data associated with a particular biopsy site marker may be collected from one or more data sources, such as a radiological report, a patient record, or personal knowledge of a medical professional. The particular biopsy site marker may be located at a biopsy site (or any other site) of a patient, such as the patient's breast. In some aspects, the marker data may include data contained in (or associated with) the first data set (e.g., marker identification information, marker characteristic information, marker image data, etc.). For example, the marker data in the second data set may be a shape identifier "corkscrew." As another example, the marker data in the second data set may be a product code (e.g., 351220). As yet another example, the marker data in the second data set may be a frequency signature associated with a material or composition of the biopsy site marker.

[0036] In other aspects, the marker data may include data not included in the first data set or may include data not used to train the AI ​​model. For example, the marker data may correspond to a newly released or non-functioning marker, or to a marker manufactured by a marker manufacturer not provided in the first data set. Furthermore, the marker data may simply be incorrect (e.g., mistyped or misapplied to a marker). As another example, the marker data may include a representation of an optimal or enhanced visualization of the image data. For example, a visual, audio, or tactile annotation or indicator may be applied to the image data to indicate an optimal visualization for viewing the placed marker. The optimal visualization may provide a consistent optical density / signal-to-noise ratio and a recommended scan plane or angle for viewing the placed marker. The representation of the optimal visualization may assist a medical professional in locating and viewing the placed marker while reading imaging data such as an ultrasound image, an x-ray image, and the like.

[0037] At operation 308, the second data set is provided as input to the AI ​​model. In some aspects, the second data set of marker data may be provided to a data processing system. The data processing system may provide the second data set to a trained machine learning model, such as the machine learning model described at operation 304. The trained machine learning model may evaluate the marker data of the second data set to identify information corresponding to the markers indicated by the marker data. For example, the marker data in the second data set may be a shape identifier "corkscrew". Based on the marker data, the trained machine learning model may determine one or more images corresponding to the "corkscrew" marker. Determining the images may include performing a match for the term "corkscrew" and receiving the corresponding images, e.g., in a local data store. Alternatively, determining the images may include generating one or more expected images of the "corkscrew" marker. For example, based on the images of the "corkscrew" marker, the trained machine learning model may construct an estimated image of the shape and location of the marker. As another example, the marker data in the second data set may be a frequency signature of a marker made of Nitinol. Based on the marker data, the trained machine learning model may determine the frequency range that is expected to be identified when a Nitinol object is detected using a particular imaging technique (e.g., ultrasound, x-ray, CT, etc.).

[0038] In some aspects, the marker data may include data on which the trained machine learning model is not trained. For example, the trained machine learning model may not correlate the shape identifier "corkscrew" with any data known to the trained machine learning model. In such an embodiment, the trained machine learning model may cooperate with one or more search utilities, web-based search engines, or remote services to search data sources (internal or external to the data processing system) using terms such as "corkscrew," "marker," and / or "image." Upon identifying one or more images associated with a "corkscrew" marker, the trained machine learning model may use the one or more images as inputs to further train the trained machine learning model.

[0039] In operation 310, a placed biopsy site marker may be identified based on the second data set. In some aspects, the data processing system may include or have access to an imaging device, such as imaging hardware 206. The imaging device may be used to collect image data and / or video data related to the placement of the biopsy site marker. For example, the data processing system may include an ultrasound transducer (probe) and corresponding ultrasound image acquisition and processing software. Sonogram images are collected in real time by the ultrasound software as the ultrasound transducer is swept over the patient's breast (e.g., the placement of the biopsy site marker). In some aspects, at least a portion of the collected image data and / or video data may be provided to a trained machine learning model. The trained machine learning model may evaluate the image / video data against the second data set. For example, continuing from the above example, sonogram images may be provided to the trained machine learning model as the images are collected. Alternatively, the trained machine learning model may be integrated into the data processing system such that the sonogram images are accessible to the trained machine learning model as they are being collected. The trained machine learning model may use an image comparison algorithm to compare one or more of the sonogram images in real time against images corresponding to data in the second data set (e.g., images of the "corkscrew" markers as identified by the trained machine learning model in act 308).

[0040] In some aspects, the trained machine learning model may identify a match between the collected image data and / or video data and the second data set. Based on the match, an indication of the match may be provided. For example, upon determining a match between at least one of the images according to the second data set and the sonogram image data, the trained machine learning model or the data processing system may provide an indication of the match. The indication of the match may inform a user of the imaging device that a placed biopsy marker has been identified. Examples of indications may include, but are not limited to, highlighting or changing the color of the identified marker in the sonogram image data, playing an audio clip or alternative sound signal, displaying an arrow indicating the identified marker in the sonogram image data, encircling the identified marker in the sonogram image data, providing a match confidence value indicative of the degree of similarity between the stored images according to the second data set and the sonogram image data, providing tactile feedback via the imaging device, etc.
