[0050] Referring now to Figure 1, this figure is a block diagram of a system 100 for guiding the positioning and orientation of an ultrasonic probe according to several embodiments of the present invention.
[0051] Referring also to Figure 2, this figure is a schematic diagram of a display 120 that presents data showing a set 210 of possible views 210a to 210n of body parts of an object scannable using an ultrasonic probe, according to several embodiments of the present invention.
[0052] Referring also to Figure 3, this figure is a schematic diagram of a display 120 that presents an image 300 including visual cues 310, 320 indicating the target position and orientation of an ultrasound probe to at least a portion of a subject, according to several embodiments of the present invention.

[0054] According to some embodiments of the present invention, the system 100 may include a computer processor 110, a display 120, an input device 130, and a memory 140 containing one or more sets of instructions 142. When executed, one or more sets of instructions 142 can cause the computer processor 110 to perform the functions described herein.
[0055] According to some embodiments, the computer processor 110 may generate an image 200 containing data showing a set 210 of possible views 210a, ..., 210n of body parts of an object scannable using an ultrasound probe (for example, as shown in Figure 2). The image 200 may include, for example, figures of views 210a, ..., 210n, lists of views 210a, ..., 210n, etc. The computer processor 110 may cause the image 200 to be displayed on the display 120. The set 210 may include at least some data collected during pulsed Doppler mode operation of the ultrasound probe.
[0056] According to some embodiments, the computer processor 110 may receive a selection of views 210 from a set of possible views 210a, ..., 210n of a body part. For example, the computer processor 110 may receive the selection using an input device 130.
[0057] According to some embodiments, the computer processor 110 can generate an image 300 (for example, as shown in Figure 3). The image 300 may include one or more visual cues indicating the target position and orientation of the ultrasound probe relative to at least a portion of the subject. The target position and orientation align the ultrasound probe and accurately obtain a selected view of the body portion.
[0058] In some embodiments, the image 300 may include a first visual cue 310 that includes a visual representation of at least a portion of the subject (for example, the torso of the subject schematically shown in Figure 3).
[0059] In some embodiments, image 300 may include a second visual cue 320, which includes a visual representation 322 of the ultrasound probe in its target position and orientation relative to the subject. In some embodiments, the visual representation 322 of the ultrasound probe may include a two-dimensional (2D) projection of a three-dimensional (3D) representation of the ultrasound probe in its target position and orientation (as shown, for example, in Figure 3).
[0060] In some embodiments, the ultrasound probe (e.g., a physical ultrasound probe) may include a physical marker on one of its sides. In some embodiments, the visual representation 322 of the ultrasound probe may include a visual marker 322a at a position corresponding to the position of the corresponding physical marker on the ultrasound probe.
[0061] In some embodiments, image 300 may include a text indicator 330 containing, for example, a written instruction (such as shown in Figure 3) or other written instructions describing the target position and orientation of the ultrasound probe relative to the subject.
[0062] According to some embodiments, the computer processor 110 may receive a dataset indicating the type of motion (e.g., sliding, rotating, tilting, oscillating), direction (e.g., upward, downward, rightward, leftward, clockwise, counterclockwise, etc.), and scale (e.g., inches, degrees, quaternions, coordinates, etc.) necessary to guide the ultrasonic probe from its current position and orientation to its target position and orientation.
[0063] According to some embodiments, the computer processor 110 can generate a dataset indicating the type, direction, and scale of motion required to guide the ultrasound probe from its current position and orientation to its target position and orientation. In some embodiments, the computer processor 110 can generate a dataset based on a selected view of a body part and at least one ultrasound image acquired by the ultrasound probe at its current position and orientation. The at least one ultrasound image can be received, for example, from an ultrasound device. In some embodiments, the computer processor 110 may determine the dataset using, for example, a trained neural network implemented on the computer processor 110. For example, the computer processor 110 can be supplied with at least one ultrasound image and a selected view of a body part as input to a neural network, which can output a dataset.
[0064] According to some embodiments, the computer processor 110 may generate one or more images 400 based on the dataset (for example, as shown in Figures 4A to 4I). Each of the one or more images 400 may include one or more visual cues indicating, for example, the type, direction, and / or scale of motion required to guide the ultrasound probe from its current position and orientation to its target position and orientation. The computer processor 110 may cause the presentation of one or more images 400 on the display 120.
[0065] In some embodiments, each of one or more images 400 may include a first visual cue 410 indicating the target position and orientation of the ultrasound probe. In some embodiments, the first visual cue 410 may include a cross diagram 412 having two bars 412a, 412b that are perpendicular to each other and intersect at intersection 412c. The cross diagram 412 may, for example, represent the proximal end of the ultrasound probe, the intersection 412c may represent the central longitudinal axis of the ultrasound probe in its target position and orientation, and the plane defined by the bars 412a, 412b of the cross diagram 412 may represent a plane perpendicular to the central longitudinal axis of the ultrasound probe in its target position and orientation. In some embodiments, the first visual cue 410 may include a visual marker 414 corresponding to the position of a corresponding physical marker on the ultrasound probe (for example, schematically shown by two arches in Figures 4A to 4I).
[0066] In some embodiments, each of one or more images 400 may include a second visual cue 420 indicating the current position and orientation of the ultrasound probe relative to the target position and orientation of the ultrasound probe. In some embodiments, the second visual cue 420 may include a 2D projection of a 3D representation of the ultrasound probe 422 in its current position and orientation. In some embodiments, the second visual cue 420 may include a cross diagram 424 having two bars 424a, 424b that are perpendicular to each other and intersect at intersection 424c. The cross diagram 424 may represent the proximal end of the ultrasound probe in its current position and orientation, the intersection 424c may represent the central longitudinal axis of the ultrasound probe in its current position and orientation, and the plane defined by the bars 424a, 424b of the cross diagram 424 may represent a plane perpendicular to the central longitudinal axis of the ultrasound probe in its current position and orientation. In some embodiments, the second visual cue 420 may include a visual marker 426 that corresponds to the position of a corresponding physical marker on the ultrasound probe (for example, schematically shown by two arches in Figures 4A to 4I).
[0067] The relative position and orientation between the second visual cue 420 and the first visual cue 410 may indicate the type, direction, and / or scale of movement required to guide the ultrasound probe from its current position and orientation to its target position and orientation.
[0068] For example, as schematically shown in Figure 4A, the relative position and orientation between the second visual cue 420 and the first visual cue 410 indicate that the ultrasonic probe should be slid to the right relative to its current position and orientation, or moved in other ways, in order to guide the ultrasonic probe to its target position and orientation.
[0069] In another example, as schematically shown in Figure 4B, the relative position and orientation between the second visual cue 420 and the first visual cue 410 indicate that the ultrasonic probe should be slid to the left relative to its current position and orientation, or otherwise moved, in order to guide the ultrasonic probe to its target position and orientation.
[0070] In another example, as schematically shown in Figure 4C, the relative position and orientation between the second visual cue 420 and the first visual cue 410 indicate that the ultrasonic probe should be slid downward relative to its current position and orientation, or otherwise moved, in order to guide the ultrasonic probe to its target position and orientation.
[0071] In another example, as schematically shown in Figure 4D, the relative position and orientation between the second visual cue 420 and the first visual cue 410 indicate that the ultrasonic probe should be rotated counterclockwise relative to its current position and orientation in order to guide the ultrasonic probe to its target position and orientation.
[0072] In another example, as schematically shown in Figure 4E, the relative position and orientation between the second visual cue 420 and the first visual cue 410 indicate that the ultrasonic probe should be tilted to the left relative to its current position and orientation in order to guide the ultrasonic probe to its target position and orientation.
[0073] In another example, as schematically shown in Figure 4F, the relative position and orientation between the second visual cue 420 and the first visual cue 410 indicate that the ultrasonic probe should be tilted to the right relative to its current position and orientation in order to guide the ultrasonic probe to its target position and orientation.
[0074] In another example, as schematically shown in Figure 4G, the relative position and orientation between the second visual cue 420 and the first visual cue 410 indicate that the ultrasonic probe should be tilted upward relative to its current position and orientation in order to guide the ultrasonic probe to its target position and orientation.
[0075] In another example, as schematically shown in Figure 4H, the relative position and orientation between the second visual cue 420 and the first visual cue 410 indicate that the ultrasonic probe should be tilted downward relative to its current position and orientation in order to guide the ultrasonic probe to its target position and orientation.
[0076] In another example, as schematically shown in Figure 4I, the relative position and orientation between the second visual cue 420 and the first visual cue 410 indicates that the ultrasound probe is in its target position and orientation. In some embodiments, the second visual cue 420 may include an indicator 427 (e.g., a text indicator 427 as schematically shown in Figure 4I) that commands the ultrasound probe to maintain its position and orientation. In some embodiments, the image 400 may include a progress bar (not shown) or other visual progress indicators (e.g., a percentage, an hourglass, etc.) that show the progress of the ultrasound scan.
[0077] In some embodiments, the distance between a designated point on a second visual cue 420 and a corresponding point on a first visual cue 410 may indicate the scale of motion (e.g., inches, degrees, quaternions, coordinates, etc.) required to guide the ultrasound probe from its current position and orientation to its target position and orientation. For example, the distance between (i) the intersection 424c of the cross diagram 424 of the second visual cue 420 and (ii) the intersection 414c of the cross diagram 412 of the first visual cue 410 may indicate the scale of motion required to guide the ultrasound probe from its current position and orientation to its target position and orientation. In some embodiments, the second visual cue 420 may include a text indicator 428 with a numerical value for quantifying the scale of motion required to guide the ultrasound probe from its current position and orientation to its target position and orientation. For example, as schematically shown in Figure 4D, the text indicator 428 indicates that the ultrasound probe should be rotated 45° counterclockwise relative to its current position and orientation in order to guide it to its target position and orientation. Please note that the text indicator 428 is shown only in Figure 4D and is not shown in Figures 4A-4C and 4E-4I for clarity.
[0078] In some embodiments, the second visual cue 420 may include an arrow 429, the shape of which may indicate the type of motion required to guide the ultrasound probe from its current position and orientation to its target position and orientation, the direction of which may indicate the direction of motion, and / or the size of which may indicate the scale of motion. For example, as schematically shown in Figure 4D, the arrow 429 indicates that the ultrasound probe should be rotated counterclockwise relative to its current position and orientation in order to guide it to its target position and orientation. Note that the arrow 429 is shown only in Figure 4D and, for clarity, is not shown in Figures 4A-4C and 4E-4I. Also note that different combinations of visual cues described herein with respect to Figures 4A-4I are possible.
[0079] According to some embodiments, the computer processor 110 can generate one or more sound cues based on a dataset that indicate the type, direction, and / or scale of movement required to guide the ultrasound probe from its current position and orientation to its target position and orientation. For example, one or more sound cues may include one or more voice or audio commands such as, for example, “rotate the ultrasound probe to the left,” “move the ultrasound probe 4 inches to the right,” and “hold the position of the ultrasound probe.” In another example, one or more sound cues may include a first sound indicating that the ultrasound probe is at its target position and orientation and that the ultrasound probe is acquiring an ultrasound image. In yet another example, one or more sound cues may include a second sound indicating that the ultrasound probe has completed acquiring an ultrasound image.
[0080] Referring now to Figure 5, this figure is a flowchart of a method for guiding the positioning and orientation of an ultrasonic probe according to several embodiments of the present invention.
[0081] In some embodiments, the method may include step 502 in which a computer processor receives or determines a dataset indicating at least one of the type, direction, and scale of motion required to guide the ultrasound probe from its current position and orientation to its target position and orientation, the target position and orientation being used to align the ultrasound probe and accurately obtain a selected view of the body part. For example, the computer processor 110 and dataset described above with respect to Figure 1.
[0082] The method may include step 504, in which a computer processor generates one or more images based on a dataset, each of which includes one or more visual cues indicating the type, direction, and / or scale of motion required to guide the ultrasound probe from its current position and orientation to its target position and orientation. For example, the visual cues 410, 420 described above with respect to Figures 4A to 4I.
[0083] The method may include step 506, in which a computer processor causes the display of one or more images generated on a display. For example, the display 120 described above with respect to Figure 1.
[0084] Referring here to Figures 6, 7, and 8, embodiments of the present invention may use data acquired in pulsed Doppler mode operation of an ultrasound probe to identify the position and orientation of the ultrasound probe and potentially assist the user in correcting or adjusting the probe's position and orientation to accurately obtain a selected / desired view of a body part. An ultrasound probe operating in pulsed Doppler mode uses the principle that moving objects affect the properties of sound waves. By transmitting short, rapid pulses of sound, an ultrasound machine (e.g., probe software) can measure the speed of movement within the body, for example, the speed of movement of fluids (e.g., blood), the movement of lungs during respiration, and the speed of movement along the digestive system, all in real time at specific locations within the body. Since blood flows according to a periodic cardiac cycle (e.g., the processes of contraction and relaxation involved in a single heartbeat), the data and / or images obtained by a probe operating in pulsed Doppler mode can be analyzed to explain variations in how the ultrasound image may appear. For example, a computer vision system may inaccurately determine the position and orientation of an ultrasound probe due to how the images obtained at that position and orientation may change as a result of specific timings in the cardiac cycle: in some images the heart may appear larger, and in others it may appear smaller (the morphology of the heart changes dramatically at different times along the cardiac cycle, and the volume of the left ventricle changes by more than 50-70% along the cycle, for example, in a healthy heart). These variations / distortions due to the temporal degrees of freedom of the ultrasound images can deceive the computer vision system into determining an inaccurate position and orientation of the ultrasound probe. In embodiments of the present invention, by using implicit or explicit information on blood flow, artificial intelligence can be helped to account for changes caused by specific timings along the cycle.
[0085] Figure 6 is a flowchart of method 600 for positioning and oriented an ultrasonic probe. Method 600 may include a step (602) of receiving a dataset derived from the ultrasonic probe. The dataset derived from the ultrasonic probe may be a dataset obtained directly from the ultrasonic probe or a dataset obtained indirectly. For example, a dataset obtained directly from the ultrasonic probe may be a time series of transducer signal data, e.g., a time series of reflection frequency measurements. A dataset obtained indirectly from the ultrasonic probe may include one (or more) images derived from measurements obtained by the ultrasonic probe. Such images may be derived by processing software / hardware and may be displayed on a computer display communicating (e.g., via wired communication) with the ultrasonic probe. Embodiments of the present invention may monitor such a display (e.g., using computer vision techniques) to receive the dataset / images.
[0086] According to a preferred embodiment, the received dataset includes at least one dataset acquired during the pulsed Doppler mode operation of the probe. The dataset acquired during the pulsed Doppler mode operation of the probe may include Doppler information / data and may include an image containing Doppler information or an image enhanced with Doppler information. The Doppler-enhanced image may be a type of image obtained during the B-mode operation of the ultrasound probe, superimposed (e.g., edited and shown by software) with colored regions (e.g., Doppler information) indicating fluid flow. For example, the Doppler-enhanced image / dataset may indicate, for example, blue, regions (e.g., pixels or data points) where fluid is flowing out of the probe by associating a first color with those regions (or "tagging" the associated data with a string, for example). Thus, in an image obtained from the probe, the blue regions can indicate that, at the time the probe was operating, those regions contained fluid (e.g., blood) that was moving away from the probe. Similarly, regions where fluid is flowing towards the probe may be associated with a second color, such as red. The fluid velocity may also be indicated by assigning color shading on a stepped scale corresponding to the velocity. For example, a rapidly flowing fluid moving toward the probe (e.g., 19 cm / sec) may be represented by dark red, while a slowly flowing fluid moving toward the probe (e.g., 4.9 cm / sec) may be represented by light red. Similarly, the velocity of a fluid moving away from the probe may be assigned to take the blue spectrum, with shading distributed according to a range of velocities from low to high (e.g., 1.5–7.1 cm / sec).
[0087] Method 600 may include a step of analyzing a dataset to identify the current position and orientation of the probe relative to a target position and orientation. The target position and orientation may be such that they represent the required position and orientation that will align the probe to accurately obtain a selected view of a body part, for example, a four-chamber view of the heart. The user of the probe (or, for example, a machine guidance process such as computer numerical control (CNC)) may change, adjust, or move the probe in a different way to match its position and orientation to the target position and orientation, and thus align the probe to obtain the desired view. According to some embodiments, the step of analyzing a dataset may include using an artificial intelligence (AI) process, for example, a neural network trained on a set of training images (e.g., a training corpus or a large collection of images). The AI process may have been previously trained in a supervised or unsupervised manner. The AI process may have been trained using labeled training data, for example, (e.g., labeled) ultrasound datasets (or images derived from such datasets) correlated with specific positions and / or orientations and / or views acquired by the probe. Training an AI process according to embodiments of the present invention may enable the AI process to output a representation of the position and orientation of the ultrasound probe, separated from the temporal degrees of freedom within the ultrasound image. For example, images of the heart taken at the same probe position at different times may appear different and may be misinterpreted by the AI algorithm as being taken from different probe positions. Since the velocity and direction of blood flow are driven by the periodic cardiac cycle, guidance in pulsed Doppler mode retains significantly more information about the timing of each frame along the cardiac cycle than B-mode ultrasound images. Furthermore, because the body is rich in blood vessels, pulsed Doppler mode images retain such information even when the heart is not in the image.
[0088] The artificial intelligence process may be a neural network (NN). The neural network may include neurons or nodes organized into layers, and links between neurons transmit outputs between them. The NN may be weighted; for example, links may have weights, and training may include adjusting the weights. Positive weights may indicate excitatory connections, and negative weights may indicate inhibitory connections. The NN is executed such that neurons, nodes, or links are "virtual" and represented by software and equations, and may be represented as equations or relationships between nodes or neurons, and the training or execution of the NN is performed, for example, by a conventional computer or a GPU (device 100 in Figure 1, etc.).
[0089] According to some embodiments, an artificial intelligence process can analyze motion within a received dataset, for example, within a body part imaged by a probe. The motion may be analyzed based on pulsed Doppler mode information received as part of the dataset. For example, the artificial intelligence process may receive Doppler-enhanced / augmented images obtained by monitoring a display communicating with an ultrasound probe. The motion can then be inferred, for example, by identifying colored regions in the monitoring image that correspond to the velocity of motion toward / away from the probe. The motion may be due to the motion of a fluid flowing through a body part at some velocity, for example, the flow of blood through a body part.
[0090] According to some embodiments, Method 600 may include the step of outputting, by an AI process, at least one of the current position and orientation of the ultrasound probe relative to a selected view, and an indication of the quality of the image produced by the ultrasound probe at its current position and orientation, wherein the image quality corresponds to whether the selected view has been achieved. The current position and orientation relative to the selected view may be communicated to the user in a manner discussed herein. The current position and orientation relative to the selected view may be the current position and orientation of the ultrasound probe compared to the position and orientation required to achieve a selected / target view of a body part. The indication of image quality may refer to the "accuracy" of the alignment of the ultrasound probe with respect to the target position and orientation required to obtain a selected view of a body part, and whether this selected view has been achieved. In other words, the AI process outputs an indication of the quality of the image produced by the ultrasound probe at its current position and orientation compared to a selected view. For example, a high-quality image may be obtained when the ultrasound probe is at the strictly precise position and orientation required to obtain a selected view of a body part, such as a parasternal long-axis view (PLAX) of the heart or an apical 4C (four-chamber) view of the heart. Low-quality images may be those obtained when the ultrasound probe is positioned and oriented far from the required / target position and orientation. As used herein, image quality does not necessarily refer to image aberrations, e.g., pixelation of the ultrasound image, but rather, as described, is a measure of how accurately the position and orientation of the ultrasound probe producing the image in question corresponds to the target position and orientation required to obtain a target / selected view of the body part. In identifying spatial and temporal degrees of freedom, embodiments of the present invention can improve ultrasound probe positioning compared to existing methods by providing guidance that takes this spatial and temporal relationship into account. According to some embodiments, Method 600 includes the step of identifying the current position and orientation of the probe relative to a target position and orientation based on at least one of the spatial and temporal degrees of freedom.
[0091] Method 600 may include a step (606) of communicating the current position and orientation of the probe relative to a target position and orientation to, for example, the user of the probe. For example, according to some embodiments, the communication step may include generating one or more images, each containing one or more visual cues indicating the current position and orientation of the probe (and, in some embodiments, the target position and orientation), based on at least a portion of the dataset, and causing the presentation of one or more images on a display. The visual cues may be, for example, cues as depicted in Figures 4A to 4I. The communication step may also include showing a graphic representation of the probe's position and orientation (P&O) and / or a graphic representation of the target position and orientation. The user can then manipulate the probe to guide it from its current P&O to the target P&O.
[0092] Alternatively, or complementary, the communication step may include presenting an image quality display scale (e.g., scale 750 in Figure 7) on the display. As described above, the image quality display may refer to a measure of the fit / alignment of the probe P&O with the target P&O required to produce a selected view of the body part. The probe P&O and the resulting image quality may also be related to motion within the body; for example, the probe may have accurate P&O to obtain a PLAX view of the heart, but the movement of the lungs during respiration obscures the heart, and therefore the image quality is lower compared to the selected PLAX view. Thus, the probe's P&O is usually accurate, but the image quality is low because the view captured by the probe at that point is not the selected / desired view. The quality display scale may be a continuous scale and may include a graphic element such as a circle (e.g., 755 in Figure 7) that can "slide" on the scale (e.g., up and down) as the determined image quality changes. Therefore, the user can fine-tune the probe's P&O (point and output) by manipulating the slider on the scale to obtain an acceptable image quality.
[0093] The communication step may also include providing one or more visual cues relating to at least one of the indications of the type, direction, and scale of motion required to move the probe from its current P&O to its target P&O, for example, by indicating arrows that show the direction of translational and / or rotational motion that the user of the probe should follow in order to accurately align the probe.
[0094] According to some embodiments, a method is provided for correcting the position and orientation of an ultrasonic probe. This method may include the step of receiving an image derived from the ultrasonic probe, for example, an image superimposed with fluid flow information acquired during pulsed Doppler mode operation of the probe. As described above, the image superimposed with fluid flow information acquired during pulsed Doppler mode operation of the probe may include colored regions indicating flow toward and / or away from the probe, and may provide an indication of fluid velocity.
[0095] The method may further include the step of analyzing an image and determining the current position and orientation of the probe relative to a target position and orientation, such that the target position and orientation align the probe to accurately obtain a selected view of the body part.
[0096] The determination step may be performed, for example, by an AI process, taking into account the probe's position and orientation based on the relationship between the temporal degrees of freedom and at least one spatial degree of freedom at the captured point in time within the periodic cycle of the fluid flow. For example, the estimated point in the periodic fluid cycle (e.g., estimated from Doppler information) may be incorporated when outputting the position and orientation and / or image quality display.
[0097] The method may also include, for example, a step of communicating to the probe user the current position and orientation of the probe relative to the target position and orientation, and an indication of the image quality as a selected view. For example, the quality indication may be high if the image is a selected view (e.g., corresponding to a selected view), and low if the image is not a selected view (e.g., not showing a selected view or not related to a selected view).
[0098] Figure 7 shows a schematic diagram of an exemplary display view 700 that may be communicated to the user of the ultrasound probe. The display view 700 may be displayed on a computer display, for example, on a display that communicates with the ultrasound probe (e.g., via a wired or wireless connection). The display view 700 may include an image 710 derived from signals acquired by the ultrasound probe (e.g., ultrasound measurements). The display view 700 may, for example, show a parasternal long axis (PLAX) view of the heart. The display 700 may also include a graphic representation of the probe's current position and orientation 725 relative to the object being observed 720 (e.g., the human body).
[0099] The display view 700 may include a tutorial (not shown), for example, text or graphical instructions on how to move the probe from its current position and orientation to a target position and orientation.
[0100] The display view 700 may also include an image quality indicator, such as an image quality scale 750. The image quality scale 750 may include graphical elements such as a slider 755 to indicate to the user the quality of the image 710, as currently obtained with the probe's P&O 725. For example, if the desired view is an apical four-ventricular view of the heart, but the captured image does not currently show a clear view of all ventricular areas, the image quality scale may indicate that the image quality is poor. Poor image quality can be corrected by moving the ultrasound probe to the target position and orientation, and the slider 755 can be moved accordingly so that the user can make final adjustments to obtain a selected view of the body part.
[0101] Region 711 of image 710 may be augmented (e.g., superimposed) with Doppler information. The augmentation may be performed by at least one processor communicating with the probe and the display. The display view 700 may show image 710 as having regions that represent motion, such as fluid motion. The display view 700 may indicate regions 712 moving toward the probe by displaying such regions in a first color, e.g., red (in the drawing, hatching and stippling are used instead of color). A scale on the display may indicate the velocity of motion, such as a shaded color scale with shading 716 representing positive velocities in the direction toward the probe, e.g., in the range of approximately 0 to 59.8 cm / sec. The display view 700 may indicate regions 714 moving away from the probe by displaying such regions in a second color, e.g., blue. The scale on the display may indicate the velocity of motion, such as a color scale of shades with shades 718 representing negative velocities in the direction away from the probe, for example, in the range of approximately 0 to -59.8 cm / second. The motion may be that of a fluid, such as blood. Embodiments of the present invention can monitor a display (e.g., a display including Doppler information) as shown in Figure 7, and computer vision techniques, screen grabs of the displayed image, and / or screen captures can be used as input to an analysis process, such as an artificial intelligence process, such as a neural network. The AI process can then analyze the image and Doppler information to output an image quality display on the probe's current position 725 and / or image quality scale 750.
[0102] According to several embodiments, a system is provided that can perform one or more steps of the methods described herein. For example, according to one embodiment, a system for positioning and aligning an ultrasound probe includes a computer processor and a memory containing one or more sets of instructions, the one or more sets of instructions, when executed, cause the computer processor to receive a dataset derived from an ultrasound probe, the dataset containing at least one dataset acquired during pulsed Doppler mode operation of the probe; analyze the dataset to identify the current position and orientation of the probe relative to a target position and orientation, the target position and orientation, align the probe to accurately obtain a selected view of a body part; and communicate the current position and orientation of the probe relative to the target position and orientation to the user of the probe.
[0103] The system may be as described in Figure 1, and may operate in conjunction with a display that communicates with an ultrasonic probe, for example, by direct monitoring of the display or by interfacing with a communication feed for the display. The system's processor may perform artificial intelligence processes to analyze the dataset, as described above.

[0106] The application backend 804 may receive multiple ultrasound images 808 and store these images for input 811 to the neural network 818. The neural network 818 may also receive metadata 814, which may include a timestamp, Doppler data, ultrasound signal data (e.g., frequency, reflectance), and data such as the patient's weight, height, age, sex, and known medical conditions. The neural network 818 may also receive a target view 816 (e.g., a desired view selected by user input) and additional parameters such as the required image quality.
[0107] The neural network 818 may analyze these inputs to determine, for example, the current position and orientation of the probe relative to the target position and orientation that will achieve the target field of view, as well as to determine the image quality display.
[0108] Post-processing operation 820 may be performed to communicate guidance to the user via the front-end graphical user interface and image quality indicators. The post-processing operation may include any logic performed to communicate navigation output and quality to the user. Input to this logic may include the output of a neural network.
