Description

Background Technology

[0001] Medical imaging practices have evolved to limit ionizing radiation to reduce its effects on patients. Consequently, the role of non-ionizing solutions, such as ultrasound, in medical imaging is increasing. One drawback of this increased use of ultrasound is the dramatic increase in workload for ultrasound technicians and ultrasound systems. Consequently, efforts are underway to prevent health problems resulting from excessive workload.

[0002] Musculoskeletal disorders are one of the leading types of work-related complaints among ultrasound technicians. Work-related musculoskeletal disorders (WRMSD) are a common cause of pain among ultrasound technicians; studies show that 80–90.5% of ultrasound technicians experience pain at least sometimes while performing ultrasound scans. WRMSD can also lead to illness, absences, surgery, and / or long-term disability. Common causes of WRMSD in ultrasound technicians include poor and / or static posture, postural changes due to variations in examination, repetitive postures and movements during multiple examinations, transducer grip pressure and exertion, psychosocial factors, and workload management issues. Common symptoms of WRMSD include aches and pains, joint stiffness, tingling, prickling, and / or burning sensations. Some ultrasound technicians may see evidence of injury, such as swelling and / or warmth in the area. Initially, the pain may be temporary and then improve when not scanning. If no action is taken, the injury may worsen, and the pain may become more frequent, eventually leading to chronic damage, which can cause persistent pain, as well as weakness, reduced mobility, and the inability to perform daily tasks.

[0003] Ergonomics is the study of human factors that affect workers, focusing on how people interact with their work environment and how to adapt the workplace based on the worker, their abilities, and limitations. For ultrasound inspectors, ergonomics involves evaluating work practices and positions taken during ultrasound scans and identifying methods to reduce the risk of injury for each operator and each type of examination.

[0004] To follow ergonomic principles, a relatively large number of sensors and, possibly, cameras will be used to sense the ultrasound technician's current setup and to allow for accurate acquisition of the technician's posture. Implementation using a relatively large number of sensors and cameras can be relatively expensive, complex to operate, and potentially impossible in some cases due to patient privacy regulations. Summary of the Invention

[0005] According to one aspect of this disclosure, a method for monitoring ultrasound technician fatigue includes: obtaining an estimated posture of the ultrasound technician at a first computer; obtaining an estimated level of repetitive movement of the ultrasound technician at the first computer based on data from sensors; obtaining an estimated level of pressure exerted by the ultrasound technician on a transducer at the first computer; and determining a level of cumulative physical injury of the ultrasound technician based on the estimated posture, the estimated level of repetitive movement, and the estimated level of pressure exerted by the ultrasound technician.

[0006] According to another aspect of this disclosure, a tangible, non-transient, computer-readable storage medium stores a computer program. When executed by a processor, the computer program causes the system to: obtain an estimated posture of an ultrasound examiner; obtain an estimated level of repetitive movement of the ultrasound examiner based on data from sensors; obtain an estimated level of pressure exerted by the ultrasound examiner on the transducer; and determine a level of cumulative bodily injury of the ultrasound examiner based on the estimated posture, the estimated level of repetitive movement, and the estimated level of pressure exerted by the ultrasound examiner.

[0007] According to another aspect of this disclosure, a system includes: a memory storing instructions; and a processor executing the instructions.

[0023] This disclosure, through its various aspects, embodiments, and / or specific features or sub-components, is intended to provide one or more of the advantages specifically stated below.

[0024] As described in this article, the variable characteristics of ultrasound systems and the activities of ultrasound technicians can be used to determine cumulative musculoskeletal damage in ultrasound technicians. The technician's posture may originate from each type of ultrasound examination performed. Repetitive movements of the technician can be obtained by sensing motion using sensors on the ultrasound line of the ultrasound system. Pressure applied to the ultrasound probe is derived based on elastography. Elastography is an ultrasound technique in which induced motion in tissue is detected by ultrasound reflection to obtain a measurement of tissue stiffness under the ultrasound probe. Various types of data can be used to estimate and monitor cumulative musculoskeletal damage. Based on recommendations in the guidelines for each category, when excessive cumulative musculoskeletal damage is predicted, changes in posture, rest, or other types of feasible remedies may be recommended. Therefore, ultrasound examination procedures can be monitored to detect signs of injury and fatigue, such as prolonged duration, repetition, and errors, and feasible remedies can be recommended when appropriate. Thus, the overall risk of musculoskeletal damage may be reduced.

[0025] Figure 1A The illustration shows a system 100A for remedying musculoskeletal injuries in ultrasound examiners according to a representative embodiment.

[0026] Figure 1ASystem 100A is a system for remedying musculoskeletal injuries in ultrasound examiners and includes components that can be provided together or separately. System 100A includes an ultrasound probe 110, an ultrasound base 120, a cable 130, and a display 180. The ultrasound probe 110 includes a processing system 115. The ultrasound base 120 includes a controller 150. The controller 150 includes at least a memory 151 for storing instructions and a processor 152 for executing instructions. Figure 8 The image depicts a computer that can be used to implement the ultrasonic base 120, but the ultrasonic base 120 may include more than Figure 8 More or fewer elements as shown.

[0027] although Figure 1A Not shown, but one or more independent analysis systems can be provided using the ultrasound system 101A and / or remotely. For example, the ultrasound system 101A can be used to provide a first independent analysis system to perform the elastography described herein, and a second independent analysis system can be provided as a cloud-based system to determine the cumulative musculoskeletal damage described herein. The first independent analysis system can perform elastography using ultrasound images obtained by the ultrasound probe 110. The second independent analysis system can obtain an estimated posture of the ultrasound examiner, an estimated level of repetitive movements of the ultrasound examiner, and an estimated level of pressure applied by the ultrasound examiner to the ultrasound probe 110. The second independent analysis system can determine the cumulative damage level of the ultrasound examiner based on the obtained information, and can provide such determinations multiple times within a workday for a single ultrasound examiner or multiple workdays for multiple ultrasound examiners. In some embodiments, the first and second independent analysis systems can be combined locally or remotely into a single independent analysis system.

[0028] An ultrasound probe 110 is connected to an ultrasound base 120 via a wire 130. A processing system 115 may include a transducer array and processing circuitry. The transducer array converts electrical energy into sound waves (which bounce off body tissue) and receives the echoes of the sound waves, converting the echoes back into electrical energy. The transducer array may include dozens, hundreds, or thousands of individual transducer elements. The ultrasound probe 110 can emit a beam to generate an image and can detect echoes. The processing system 115 can process the ultrasound images captured by the ultrasound probe 110.

[0029] An ultrasound base 120 is connected to an ultrasound probe 110 via a cable 130. The ultrasound base 120 may be an ultrasound cart or include an ultrasound cart. In addition to the controller 150, the ultrasound base 120 may also include buttons as a user interface. The main user interface of the ultrasound base 120 may be buttons or include buttons. These buttons may correspond to different functions of the ultrasound base 120, and the ultrasound technician can readily identify which buttons to press to control the different functions of the ultrasound base 120 and the ultrasound probe 110. To some extent, any action performed for an ultrasound session can be prepared, selected, and optimized by pressing a certain sequence of buttons. The ultrasound technician's ultrasound procedures may depend on the characteristics of the ultrasound base 120, including the ultrasound probe 110's dependence on the ultrasound base 120, and the workflow centered on the ultrasound base 120. Some or all of the ultrasound examination-related activities performed by the ultrasound technician may be reflected through certain operations on the ultrasound base 120. Certain specific button sequences on the ultrasound base 120 can be used to prepare, select, and optimize relevant ultrasound examination operations. The sequence of button presses on the ultrasound base 120 can be collected and stored in a log file maintained by the ultrasound base 120.

[0030] The controller 150 includes at least a memory 151 and a processor 152. The controller 150 may also include other types of interfaces, such as ports, disk drives, wireless antennas, or other types of receiver circuitry that connect the controller 150 to other electronic components. The memory 151 may store instructions executed by the processor 152. The memory 151 may also store a log file created by the ultrasound base 120. The log file may store records of ultrasound procedure types performed by the ultrasound examiner and records of the sequence of button presses performed during each procedure. Examples of log files include ordered data of events and input markers provided via a user interface. The ordered arrangement of data may include timestamps, input types, workflows such as data types, and the sequence of buttons pressed during the workflow. The sequence of button presses may also be provided as statistical data, such as counts and percentages of specific operations, such as freeze, acquisition, depth change, zoom, scan, erase, update, and other types of operations performed when a specific button on the ultrasound base 120 is pressed.

[0031] Display 180 may be located locally on the ultrasound base 120. Display 180 can be connected to the ultrasound base 120 via a local wired interface (e.g., Ethernet cable) or a local wireless interface (e.g., Wi-Fi connection). Display 180 can be connected to other user input devices through which the user can input commands, including a mouse, keyboard, finger wheel, etc. Display 180 may be a monitor, such as a computer monitor, a display on a mobile device, an augmented reality display, a television, an electronic whiteboard, or another screen configured to display electronic images. Display 180 may also include one or more input interfaces (e.g., the input interfaces mentioned above that can be connected to other components or parts), and an interactive touchscreen configured to display prompts to the user and collect touch input from the user.

[0032] Processing system 115 and / or controller 150 can directly perform some of the operations described herein and can indirectly implement other operations described herein. For example, processing system 115 can directly implement the operation of ultrasound probe 110. Controller 150 can directly control operations, such as logical operations performed by processor 152 executing instructions from memory 151 based on input received via an interface from electronic components and / or the user. The processes implemented by controller 150 may also include steps not directly performed by controller 150. For example, controller 150 can indirectly control operations, such as by generating and transmitting content to be displayed on display 180. Of course, the specific arrangement and relative functions of controller 150 and processing system 115 can vary within the scope of this embodiment.

[0033] Among the technical features performed by the ultrasound system 101A, the controller 150 can execute software to perform the various functions described herein. For example, the controller 150 can execute instructions to acquire and process log files stored in memory 151 to extract relevant data. Relevant data may include, for example, button presses, timestamps, increment times, acquisition settings, examination type, and whether an ultrasound image was acquired. The controller 150 can also execute instructions to estimate the current ultrasound equipment settings, such as estimating whether the ultrasound examiner is sitting or standing based on the type of ultrasound procedure, the configuration of the ultrasound stand 120, and / or the demographic characteristics of the ultrasound examiner. Patient demographics may also be considered when data reflects that the patient's demographics could lead to musculoskeletal injury for the ultrasound examiner. For example, patient data that may be considered might include height or weight. The controller 150 can also execute instructions to estimate the current ultrasound examiner posture, such as based on the type of ultrasound procedure being performed and the buttons pressed by the ultrasound examiner during the ultrasound procedure. Posture can be determined based on log file data reflecting which buttons were pressed and / or based on input received directly from the ultrasound examiner indicating the type of procedure being performed.

[0034] The controller 150 can also determine the level of repetitive movements performed by the ultrasound technician. A sensor can be provided on line 130. This sensor can be a hardware sensor used to measure distance and motion to determine the repetition of the ultrasound technician's movements. This sensor can be used to determine repeatability without requiring visual information such as from a camera. The sensor can be accurate to the sub-millimeter level and provides detailed definitions and historical data about the ultrasound technician's repetitive movements. The controller 150 can use data from the sensor on line 130 to estimate the current level of movement repetition. The sensor on line 130 can be novel hardware in the context of the ultrasound system 101A and can include a telescopic pull-wire displacement sensor integrated in line 130 using micro-deflection pulleys. The telescopic pull-wire displacement sensor can be used to determine the sensor's displacement, and the estimated level of the ultrasound technician's repetitive movements can be estimated based on the determined sensor displacement.

[0035] Additionally, the controller 150 or the first independent analysis system local to the ultrasound system 101A can perform elastography and then send the elastography results to the second independent analysis system.

[0036] Figure 1A The configuration of the ultrasound system 101A does not specifically require a camera to monitor the ultrasound technician. While a camera could be used to monitor the ultrasound technician to provide input for the analysis described herein, such a camera is not particularly necessary for the ultrasound system 101A. Instead, log file data from the ultrasound base 120, other information input by the ultrasound technician, and repetitive data from sensors on line 130 can serve as input for the analysis described herein, even if other types of information can be used as enhancements in some embodiments.

[0037] Figure 1B The illustration shows another system for remedying musculoskeletal injuries in ultrasound examiners, according to a representative embodiment.

[0038] exist Figure 1B The system includes an ultrasound system 101B. Besides... Figure 1AIn addition to the components of system 100A, ultrasound system 100B also includes a first independent analysis system 140. The first independent analysis system 140 includes a memory 141 and a processor 142. The first independent analysis system 140 is located locally on ultrasound base 120 and can be configured to perform elastography as described herein. That is, instructions stored in memory 141 can be executed by processor 142 to process ultrasound images received from ultrasound base 120. Memory 141 may also include one or more anatomical structural models for use in performing elastography. Elastography can be performed to determine the pressure applied to ultrasound probe 110 based on analysis of ultrasound images captured by ultrasound probe 110. Elastography can also rely on characteristics of each ultrasound examination, such as using a structural model corresponding to the type of each ultrasound examination. The structural model used in elastography can be determined based on log file data stored in memory 151 of controller 150.

[0039] Figure 1C The illustration shows another system for remedying musculoskeletal injuries in ultrasound examiners, according to a representative embodiment.

[0040] exist Figure 1C In the middle, system 100C includes Figure 1B The ultrasound system 101B in the middle. Besides... Figure 1B In addition to the components of the ultrasound system 101B, system 100C also includes a network 199 and a second independent analysis system 190. Network 199 may include a wide area network such as the Internet. The second independent analysis system 190 may include a remote system located away from the ultrasound system 101B. For example, the second independent analysis system 190 may include a cloud-based system implemented using one or more data centers, each configured with a combination of servers and large storage paired with the servers. The second independent analysis system 190 can perform the determination of cumulative physical damage for one or more ultrasound examiners in one or more facilities. The second independent analysis system 190 can perform such determinations 24 hours a day, 7 days a week, and 365 days a year, for example, as a service for geographically distributed ultrasound examiners.

[0041] The second independent analysis system 190 can be a cloud-based system and can assess the stress exerted by the ultrasound technician on the transducer of the ultrasound probe 110. Current physical damage to the ultrasound technician can be cumulatively determined by monitoring various data collected from ultrasound session data (including ultrasound images). The current physical stress of the ultrasound technician can be compared to thresholds to assess whether an alternative standard modality should be recommended for the selected type of ultrasound acquisition, or whether the ultrasound technician should rest or perform rehabilitation exercises. As mentioned above, various demographic data of the ultrasound technician can be considered when assessing cumulative damage.

[0042] Figure 2 The illustration depicts a method for remedying musculoskeletal injuries in ultrasound examiners according to a representative embodiment.

[0043] This article provides guidance on solutions for minimizing or preventing musculoskeletal and ergonomic injuries to ultrasound technicians during routine ultrasound procedures. These guidelines help alleviate musculoskeletal disorders, which are a common cause of pain and illness-related absences for ultrasound technicians.

[0044] Figure 2 The method begins at S261, obtaining an estimated level of repetitive movement by the ultrasound examiner. Repetitive movement is a common cause of musculoskeletal disorders and the level of repetitive movement can be determined by the displacement detected by a sensor on monitoring line 130.

[0045] At S262, the estimated posture or position is obtained. Data used to assess posture may include whether the ultrasound technician is sitting or standing, and whether the technician is likely to bend over or exert force. Posture can be estimated based on the type of ultrasound examination performed and known physical characteristics of the ultrasound base 120 and / or demographic characteristics of the ultrasound technician and / or patient. Posture can be estimated based on log file data of the ultrasound base 120, such as the sequence of buttons pressed by the ultrasound technician on the ultrasound base 120 and the relative position of each button. Posture can be determined based on input directly from the ultrasound technician or based on determinations derived directly from the ultrasound technician's input. The estimation at S262 can be performed without requiring any camera input to monitor the ultrasound technician's ergonomic information.

[0046] At S263, the estimated pressure level is obtained. Excessive pressure on the ultrasound probe and poor grip on the ultrasound probe are common sources of musculoskeletal disorders. Elastography can be used to assess the pressure level at S263. Elastography is used to derive the pressure level on the ultrasound probe 110 using ultrasound images because pressure applied to the ultrasound probe 110 results in horizontal rather than vertical shear waves. The amount of pressure applied to the ultrasound probe 110 can be inferred from the motion derived from the acquired ultrasound images. The type of examination in progress can also be used, as long as this type of information reflects the location that the ultrasound probe 110 will reach. Using information from the ultrasound images, the type of examination, and characteristics of the patient's body, the estimated pressure level on the ultrasound probe 110 can be estimated. In some embodiments, the sequence of button presses reflected in the log file data can be used to determine the tissue mechanical model of the examination area, and the determined mechanical model can be used to perform elastography to derive the pressure level. In some embodiments, S263 can be... Figure 1B and Figure 1CThe first independent analysis system 140 in the process executes the analysis. In other embodiments, S263 may be performed by... Figure 1C The second independent analysis system 190 in the process is executed, such as when ultrasound images are sent to a remote cloud service that performs elastography.

[0047] In S272, the level of cumulative damage is determined. The level of cumulative damage can be determined based on estimates at S261, S262, and S263. For example, cumulative damage may reflect damage from a single ultrasound session, or damage from multiple ultrasound sessions involving the same sonographer in a continuous sequence or over a period of time (such as a workday). S272 can be determined by... Figure 1C The second independent analysis system 190 is executed and can be performed for multiple ultrasound examiners and multiple ultrasound systems.

[0048] In S281, it is determined whether the level of cumulative damage exceeds a threshold. S281 can be determined by… Figure 1C The second independent analysis system 190 is executed and can be performed for multiple ultrasound examiners and multiple ultrasound systems.

[0049] If the cumulative damage level exceeds the threshold (S281 = Yes), then at S292, potential alternative remedies are assessed and presented to the ultrasound examiner. The assessment at S292 can be conducted by… Figure 1C The second independent analysis system 190 is executed, and the presentation at S292 can be performed using the display 180. Figure 2 The estimation and determination of musculoskeletal damage in ultrasound technicians may be an automated assessment and can be performed throughout the technician's workday. By passively monitoring ultrasound technicians, alternative and feasible remedies can be provided when appropriate. Alternative remedies may include preventative measures such as alternative procedural standard patterns, rest, or rehabilitative exercises.

[0050] If the cumulative damage level does not exceed the threshold (S281 = No), then Figure 2 The method returns to S261.

[0051] Figure 2 Other types of factors can also be considered in this approach. For example, stress or workload caused by workload management issues can be considered. Examples of stress or workload factors might be the length of the workday, such as extending the workday from 8 hours to 12 hours. Another example of stress or workload factors might be the number of consecutive working days, such as an ultrasound technician performing ultrasound examinations for 4 hours or more per day for 6 consecutive days or longer. Furthermore, stress or workload might be caused by psychosocial factors, such as limited support for ultrasound technicians.

[0052] Figure 3The illustration shows another method for remedying musculoskeletal injuries in ultrasound examiners, according to a representative embodiment.

[0053] Figure 3 The method can be executed, mostly or entirely, using software modules executed by controller 150, first independent analysis system 140 and / or second independent analysis system 190.

[0054] Figure 3 The method begins with S301. Figure 3 The method mainly includes the steps shown in the left, right, and middle columns. The left column includes steps directly related to the use of displacement sensors (such as sensors attached to line 130). The middle column includes steps directly related to the use of ultrasonic equipment, such as ultrasonic base 120 and ultrasonic probe 110. The right column includes steps directly related to the use of analysis systems for analyzing ultrasonic images, such as a first independent analysis system 140 or a second independent analysis system 190.

[0055] First, the intermediate steps directly related to the use of the ultrasound machine are described. At S312, the ultrasound procedure standard is obtained. S312 relates to the characteristics of the direct execution of the ultrasound machine (such as the ultrasound base 120). The ultrasound procedure standard obtained at S312 can be selected from a set of multiple local standard procedures for all types of ultrasound examinations that an ultrasound examiner can perform. Such ultrasound procedure standards are detailed guidelines that include precise specifications of the position and type of movement that the ultrasound probe 110 must follow to perform a correct examination. Standard practice is to draw upon guidelines from other countries and adapt them to the local context if no explicit national guidelines are available for the object. Detected variations can be analyzed based on log files and repetition of actions to adjust the assessment.

[0056] In S322, an ultrasound machine is set up. The ultrasound machine set up in S332 may include an ultrasound probe 110 and an ultrasound base 120.

[0057] At S332, the ultrasound machine settings are acquired. The ultrasound machine settings acquired at S332 can be acquired by the second independent analysis system 190.

[0058] At S342, the ultrasound machine log file is acquired. The log file contains log file data that can be used to estimate the ultrasound technician's posture and to determine the mechanical model for elastography. The log file data may include a sequence of one or more buttons pressed by the ultrasound technician on the ultrasound base 120.

[0059] At S352, the ultrasound machine log file data is parsed. The software module can parse the log file data written in real time during each ultrasound examination. The software module can extract pressed buttons, the timestamps associated with each button press, and any other specific information that can be used to estimate the ultrasound technician's posture.

[0060] At S362, the current ultrasound technician posture is estimated. All the aforementioned data collected in S312, S332, and S342 can be used to form the input for estimating the current ultrasound technician posture. The associated posture can be determined from the standard sequence of events described in the guide obtained in S312. The timestamps between button presses obtained from the log file data at S342 can be used to estimate the length of the posture and even the deviation from the guide.

[0061] The following describes the steps directly related to the analysis system. In S313, data is acquired from the ultrasound image. Data can be acquired by analyzing the ultrasound image obtained from the ultrasound base 120. For most embodiments herein, the data from the ultrasound image is acquired from a real-time feed from the ultrasound probe 110.

[0062] At S323, data is obtained from the mechanical model of the tissue. Data can be acquired from memory 141 at S323. Data from the ultrasound images acquired at S313 is combined with a standard mechanical model of the tissue surrounding the examination area obtained at S323. The standard mechanical model of the tissue to be used can be determined based on the log file data acquired at S342 and the ultrasound image data obtained at S313.

[0063] At S363, elastography can be performed to estimate the applied pressure. Elastography is used to determine the body stress (or force or pressure) applied to the ultrasound probe 110 during an ultrasound examination. The data obtained at S313 and S332 can form the input to a trained artificial intelligence model, combined with the physical / mechanical model obtained at S323, and trained to estimate the applied probe pressure based on the deformations shown in the ultrasound images. Deformations include vertical / displacement and longitudinal / shear, as shown in the ultrasound images.

[0064] Next, the left-hand column of steps directly related to the ultrasonic base 120 is described. In S351, data is obtained from the displacement sensor on line 130. The data obtained at S351 is collected over time based on the movement of the displacement sensor on line 130.

[0065] In S361, repeatability is estimated based on data of the determined displacement obtained from the displacement sensor. The data collected in S351 is used in S361.

[0066] Based on the steps in the left and middle columns, a clear picture of the ultrasound technician's posture and movements can be seen between button presses. Based on the steps in the right column, additional inputs obtained from elastography can be identified. The collected data can be provided to a second independent analysis system 190 during or after each ultrasound examination performed by the ultrasound technician.

[0067] At S371, inputs from S361, S362, and S363 are obtained to estimate the current musculoskeletal injury of the ultrasound examiner. The inputs can be summed or otherwise combined to reflect one or more values ​​that can be compared with a threshold at S381. The current cumulative musculoskeletal injury of the ultrasound examiner is estimated at S372. At S372, the current musculoskeletal injury of the ultrasound examiner is estimated based on the repetition estimated at S361, the current ultrasound examiner posture estimated at S362, and the inputs from the elastography performed at S363. Additionally, one or more previous values ​​obtained by the ultrasound examiner from previous ultrasound examinations are also considered.

[0068] S372 based on Figure 3 The steps performed in the left, middle, and right columns of the diagram collect and estimate all the information. The estimation at S372 can be performed using an artificial intelligence model that integrates three main injury variables: posture, repetition of motion, and probe pressure. The artificial intelligence model can be implemented in a cloud-based system and can take into account significant deviations in workflow analysis recorded in the log file from ultrasound base 120 to adjust the estimation of the standard procedure. The artificial intelligence model can also take the amount of time spent by the ultrasound examiner at each stage, the number of repetitions, and other types of relevant inputs as inputs. The artificial intelligence model can evaluate various input data to filter out situations where the ultrasound examiner talks to the patient or pauses, such as when the hardware sensors on cable 130 do not detect any motion, and when no ultrasound images are acquired.

[0069] In S381, it is determined whether the sum of accumulated damage exceeds a threshold. Once the estimation at S371 is completed, the determination at S381 is performed to determine whether the current damage level exceeds a specified given amount (such as a threshold).

[0070] If the sum does not exceed the threshold (S381 = No), the process returns to S301.

[0071] If the sum is higher than the threshold (S381 = Yes), then the next step is to determine whether the check is complete at S391. If the check is complete (S391 = Yes), then... Figure 3 The method ends in S399.

[0072] If the examination is not completed (S391 = No), but the total exceeds the threshold (S381 = Yes), then in S392, potential alternative remedies are assessed and presented to the sonographer, and the process then returns to S301. Alternative feasible remedies can be provided via audio messages or displays, aiming to suggest alternatives, such as alternative movements for performing the examination and / or advising the sonographer to take a break. Alternative feasible remedies may also include recommendations for some rehabilitative exercises targeting the most severely affected areas (such as the hand, shoulder, or neck) as defined by the damage analysis.

[0073] The algorithm, which runs locally in the ultrasound base 120, can run until the end of each ultrasound examination and provide data and / or ultrasound images to the first independent analysis system 140 and / or the second independent analysis system 190.

[0074] although Figure 3 The procedure is shown to end at S399 when the current ultrasound examination is completed, but remedial measures can still be suggested to the ultrasound technician before the procedure ends. For example, if the accumulated damage to the ultrasound technician exceeds a predetermined threshold, the ultrasound technician can be warned to take a break before the next ultrasound examination. In some embodiments, when the accumulated damage to the ultrasound technician exceeds the predetermined threshold, the second independent analysis system 190 can notify the administrator so that the administrator can intervene as appropriate.

[0075] Figure 4 The illustration shows another system for remedying musculoskeletal injuries in ultrasound examiners, according to a representative embodiment.

[0076] Figure 4 An example of a telescopic wire displacement sensor using a deflecting pulley is shown. Figure 4The system shown includes a first pulley 431, a second pulley 432, a wire 433, and a sensor 435. The wire 433 may include a portion of the sensor 435 and is designated by a circular feature indicating the distal end of the wire. The sensor 435 is a displacement sensor and may include another pulley with a wire wound around it, such that one end of the wire is attached to the pulley. The distal end of the wire 433 is located away from the housing of the sensor body of the sensor 435, which includes a pulley around which the proximal end of the wire 433 is wound. The pulley of the sensor 435 may be secured to an ultrasound base 120. The first pulley 431 includes an outer protective surface 431A and a spool 431B, and the portion of the wire 433 of the sensor 435 is wound around the spool 431B. The second pulley 432 may include a similar configuration to the first pulley 431. The housing of the sensor body of the sensor 435 may be attached directly or indirectly to the ultrasound base 120. For example, the sensor 435 may be attached to the ultrasound base 120 near the probe cable connection, but this is not particularly required. The distal end of sensor 435, defined by the circular feature of wire 433, can be directly attached to ultrasonic probe 110 or a probe cable near ultrasonic probe 110. Sensor 435 measures the number of times the wire is wound or unwound around its pulley, including partial winding or unwinding. Therefore, the housing of sensor 435 is fixed to ultrasonic base 120 and senses the internal movement of the wire generated by winding or unwinding.

[0077] Since the line of sensor 435 is displaced based on the movement of line 433, the movement of the line of sensor 435 can be sensed and recorded as data.

[0078] Figure 5 The illustration depicts a user interface for remedying musculoskeletal injuries in ultrasound examiners, according to a representative embodiment.

[0079] A software module executed by controller 150 can detect the settings of the ultrasound system, including ultrasound base 120. Detection may include determining whether the ultrasound technician is standing or sitting. This setting can be read from a log file stored in memory 151, inferred by applying artificial intelligence to data from ultrasound base 120, or even obtained directly from the ultrasound technician via input to ultrasound base 120. Alternatively, sensors placed in the ultrasound system display and keyboard position adjustment arm can provide data to controller 150 indicating the estimated posture of the ultrasound technician.

[0080] Figure 6 The illustration shows another system for remedying musculoskeletal injuries in ultrasound examiners, according to a representative embodiment.

[0081] Figure 6The system includes a first pulley 631, a second pulley 632, and a line 633. As shown, the pulleys are fixed deflection pulleys along the line 633 from the ultrasound probe to the ultrasound base, and are used to track the repetition of ultrasound probe movement through a bidirectional correlation with the displacement measured by a pull-wire sensor. That is, the amount of elongation of the line 633 is sensed by the pull-wire sensor, and this is used to determine the level of repetition performed by the ultrasound technician. An alternative embodiment of the device (not shown) integrates the pulleys and line into the probe cable itself. The pulleys and line are mounted in place along the probe cable for compactness and ease of use. The level of repetition is used to better indicate damage between button presses.

[0082] Figure 7 An ultrasound probe is shown according to a representative embodiment in a system for remedying musculoskeletal injuries in ultrasound examiners.

[0083] Figure 7 The principle of ultrasonic elastography using pressure waves and shear waves induced by an ultrasonic probe is illustrated. Figure 7 One or more shear waves S are marked in the middle. Figure 7 The ultrasonic probe 710 shown can correspond to Figure 1A The ultrasound probe 710 is used in the ultrasound system. Elastography is used to estimate the pressure applied to the ultrasound probe 710 by the ultrasound examiner without any additional sensors (such as a monitoring camera). Elastography can be performed using software modules executed by the controller 150 or by the first independent analysis system 140 or the second independent analysis system 190.

In embodiments, computer system 800 can be implemented using electronic devices that provide voice, video, or data communication. Furthermore, while computer system 800 is shown as a monolith, the term "system" should also be considered as a collection of any systems or subsystems that individually or jointly execute one or more sets of software instructions to perform one or more computer functions.

[0087] like Figure 8 As shown, computer system 800 includes processor 810. Processor 810 can be considered a representative example of a processor of a controller and executes instructions to implement some or all aspects of the methods and processes described herein. Processor 810 is tangible and non-transient. As used herein, the term "non-transient" should not be construed as a permanent characteristic of a state, but rather as a characteristic of a state that will persist for a period of time.

[0095] Therefore, the variable characteristics of ultrasound and ultrasound technician activity can be used to determine cumulative musculoskeletal damage. Ultrasound machine log file data can be used to identify procedures and how these procedures evolve over time. Other types of information, such as patient biometric data, can also be used to predict ultrasound technician fatigue. Various types of data can be used to estimate and monitor ultrasound technician posture against standard positioning for each ultrasound examination and assess cumulative musculoskeletal damage. Based on recommendations in the guidelines for each category, when excessive cumulative damage is predicted, changes in posture, rest, or other types of feasible remedies may be recommended. Therefore, ultrasound examination procedures can be monitored to detect signs of damage and fatigue, such as prolonged duration, repetition, and errors, recommending remedies when appropriate and reducing the overall risk of musculoskeletal damage.
