Abstract
Description
[0001] A PORTABLE IMAGING SYSTEMS AND METHODS THEREOF
[0002] Field of the Invention
[0003] [1] The present invention relates to electromechanical imaging systems and methods for automated medical imaging, and in particular to portable imaging systems using automated ultrasound probes.
[0004] [2] The invention has been developed primarily for use with patients for imaging their bodies by employing a fully autonomous, clinical-grade robotic ultrasound imaging system designed for regulated medical device markets and will be described hereinafter with reference to this application. It will, however, be appreciated that the invention is not limited to this particular field of use.
[0005] Background of the Invention
[0006] [3] Ultrasound scans are widely used in the medical field, serving as a key imaging tool. They are commonly employed in diagnosing conditions affecting the kidneys and gallbladder, such as stones and other anomalies. It is assumed that if people have the facility of getting themselves checked over short periods of time, at low cost and convenience, it is possible to detect pathological conditions at earlier stages. This would allow for “treatment in time” to save the lives of a large number of people. However, access to skilled sonologists remains a significant challenge, particularly in remote and resource-limited regions. The availability of trained professionals is limited, leading to delays in diagnosis and treatment. Additionally, conventional ultrasound systems require manual operation, demanding both expertise and precision to ensure accurate imaging. The reliance on human operators introduces variability in scan quality and repeatability, posing concerns for consistent and reliable imaging. These limitations create a need for alternative solutions that can enhance accessibility, accuracy, and efficiency in ultrasound imaging.
[0007] [4] To address these challenges, robotic ultrasound systems have been developed. These systems can acquire ultrasound images with greater efficiency and consistency, potentially reducing patient wait times and enhancing the overall quality and repeatability of scans.
[0008] [5] Existing solutions to address this issue also include portable ultrasound devices, tele-robotic ultrasound systems, and semi-automated robotic imaging systems. Portable ultrasound devices have improved accessibility by enabling point-of-care imaging, allowing healthcare workers to conduct ultrasound scans outside traditional clinical settings.
[0009] [6] Tele-robotic ultrasound imaging enables remote specialists to operate the device. Semi-automated robotic systems integrate robotic arms and artificial intelligence to aid in probe positioning and scanning, reducing the dependency on human expertise.
[0010] [7] However, these approaches still require operator intervention or external guidance. Currently, prior art systems are either manual or tele-robotic systems that require human intervention during imaging operations.
[0011] [8] Despite advancements, these existing solutions exhibit several limitations. Normally, people do not get themselves diagnosed for diseases or abnormalities until advanced-stage symptoms become evident. This issue is exacerbated by the supplydemand gap, where the number of expert sonologists available to diagnose a population is limited, and they can only perform a finite number of scans within a given timeframe. As humans, their speed and efficiency are limited and variable. The availability and speed of imaging services are primary concerns, as large populations cannot be effectively scanned repeatedly over extended periods.
[0012] [9] Portable ultrasound devices often suffer from inconsistent imaging quality due to operator variability, leading to sub-optimal scans that may require repetition. Tele-robotic ultrasound systems depend on stable internet connectivity and real-time communication, which may not be feasible in remote or low-resource environments. Semi-automated robotic systems still require partial human involvement, necessitating trained personnel for setup, calibration, and intervention during scanning. Furthermore, the high costs associated with advanced robotic solutions make them impractical for widespread deployment, particularly in underserved regions. These shortcomings indicate the need for a more autonomous, reliable, and cost-effective solution.
[0013]
[0010] Furthermore, prior art autonomous robotic systems require instrument-level physical precision during site deployment; technicians must ensure the operating chassis and camera gantries are perfectly levelled using external tools. Any mechanical skew or uneven flooring completely degrades the spatial coordinate mapping of the robotic arms. Semi-automated systems currently present in the art suffer from inherent computational latency during sudden biological anomalies. They also fail to account for "catastrophic forgetting" during continuous neural networktraining, and frequently lack explicit medical-grade cybersecurity frameworks and algorithmic provenance, exposing them to enablement and regulatory rejections.
[0014]
[0011] The present invention seeks to provide an imaging system and a method for imaging, which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative.
[0015]
[0012] It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country.

[0265]
[0277] Figure 5 illustrates a hybrid active-passive compliant end-effector assembly 300 configured to serve as a probe shock absorber and force-regulated interface between a robotic manipulation assembly and a biological target.
[0266]
[0278] The assembly 300 comprises a protective shroud 301 , configured to enclose internal sensing components and shield them from environmental contamination and mechanical damage during operation. A plurality of Time-of-Flight (ToF) infrared sensor ports 302 are provided within the shroud 301 , configured to house proximity sensing elements that detect the distance between the end-effector and a biological surface.

A plurality of bolt holes 304 are provided in the coupling plate 303, enabling secure attachment to the robotic arm and ensuring structural rigidity under dynamic loading conditions.
[0267]
[0279] A cable exit 305 is provided to route electrical wiring associated with sensors and the ultrasound probe, enabling communication with the localised edge-processing module.
[0268]
[0280] The compliant assembly 306 comprises a rigid upper housing coupled to a floating lower carriage via a plurality of compression springs 310, configured to provide passive compliance along a primary axis of motion.
[0269]
[0281] The springs 310 are arranged symmetrically and are pre-compressed to establish a predefined breakaway force threshold, mathematically defined as:
[0270]
[0271]
[0282] Each compression spring 310 is geometrically constrained such that its free length divided by its mean diameter satisfies a slenderness ratio of:
[0272]
[0273] thereby rendering the springs inherently resistant to lateral buckling independent of internal guide structures.
[0274]
[0283] The floating carriage is constrained to linear motion via a pair of rigid guide structures comprising roller bearings and pins 309, which are inserted into corresponding vertical guide cavities defined by vertical holes 312.
[0275]
[0284] The roller bearing and pin assemblies 309 ensure that the carriage translates along a controlled axis, thereby preventing rotational or lateral displacement during compression.
[0276]
[0285] A cable hole 311 is provided within the assembly to route internal wiring through the moving carriage without mechanical interference.
[0277]
[0286] The assembly 300 further comprises a probe holder 307, configured to securely retain an ultrasonic transducer probe 308.
[0287] The probe 308 is positioned such that it maintains consistent contact with a biological surface during operation, with the compliant mechanism absorbing dynamic forces and maintaining stable acoustic coupling. A 6-axis force-torque sensor 313 is mounted proximally to the coupling plate 303, configured to measure multi-axis force and torque vectors generated during probe contact. The force-torque sensor 313 operates in conjunction with the compliant mechanism 306, providing real-time feedback to the localised edge-processing module to regulate applied forces and maintain safe interaction with the patient.
[0278]
[0288] As shown in Figure 5, the ToF sensors located within ports 302 detect the proximity of a biological surface, enabling controlled approach of the end-effector prior to contact. Upon contact, the compliant mechanism 306 allows controlled compression of the springs 310, thereby absorbing impact forces and maintaining a consistent contact pressure. The roller-guided carriage defined by components 309 and 312 ensures linear displacement, preserving probe alignment and preventing off-axis loading. The force-torque sensor 313 continuously monitors applied forces, enabling the control system to adjust robotic motion via inverse kinematics and reinforcement learning-based trajectory optimisation. Advantageously, the hybrid active-passive compliant end-effector assembly 300 illustrated in Figure 5 provides a mechanically robust and mathematically predictable force-regulation interface that combines passive compliance with active sensing. This configuration enables precise control of probe contact forces, reduces the risk of patient discomfort or injury, and ensures consistent acoustic coupling, thereby enhancing imaging accuracy and system reliability.
[0279]
[0289] Figure 6 illustrates a passive dynamic end-effector exchange coupling 400 configured to enable automatic tool attachment and detachment at distal extremities of the robotic system without the use of active pneumatic, hydraulic, or electromagnetic actuation. The coupling comprises an ATC master plate 401, configured to be rigidly mounted to a terminal joint of a robotic arm. A plurality of bolt holes 402 are provided to facilitate secure mechanical fastening of the master plate 401 to the robotic structure, ensuring transmission of torque and axial loads during operation. A latch lock cavity 403 is formed within the master plate 401 , configured to receive and mechanically engage a corresponding latch element of a mating slave plate.

The coupling 400 further comprises an ATC slave plate 408, configured to be rigidly integrated with an interchangeable endeffector, including but not limited to an ultrasound probe, gel dispenser, or cleaning tool. A hole for cable pass-through 409 is provided in the slave plate 408 to route internal wiring from the end-effector to the connector interface. A plurality of pogo pins 410 are arranged on the slave plate 408, configured to establish spring-loaded electrical contact with the electrical connector port 407 of the master plate during coupling. The slave plate 408 further comprises one or more latch elements 411 , configured to mechanically engage with the latch lock cavity 403 of the master plate. A plurality of bolt holes 412 are provided to secure the slave plate 408 to the endeffector structure. The latch elements 411 are configured to engage the latch lock cavity 403 through purely mechanical interaction, thereby securing the slave plate 408 to the master plate 401 without requiring active actuation. A plurality of latch release buttons 413 are positioned on the slave plate 408, configured to mechanically disengage the latch elements 411 when simultaneously actuated. The latch mechanism is configured such that engagement occurs automatically upon insertion and alignment of the plates, while disengagement requires coordinated mechanical actuation, thereby preventing accidental decoupling. A plurality of alignment pin holes 414 are provided on the slave plate 408, configured to receive the alignment pins 406 of the master plate. The engagement between alignment pins 406 and alignment pin holes 414 ensures precise radial and axial alignment of the coupling interface. The pin-hole interface further provides anti-rotation constraint, preventing torsional misalignment and ensuring consistent orientation of the end-effector during operation.
[0280]
[0290] Upon coupling, the pogo pins 410 engage the electrical connector port 407, thereby establishing electrical communication between the robotic arm and the attached end-effector. The spring-loaded nature of the pogo pins 410 compensates for minor mechanical tolerances and ensures reliable electrical contact under dynamic loading conditions.
[0291] As shown in Figure 6, the robotic arm positions the master plate 401 in alignment with the slave plate 408 located at a docking station positioned at the distal extremity of a horizontal translational axis. As the plates are brought into contact, the alignment pins 406 enter the alignment pin holes 414, guiding the coupling interface into precise alignment. Continued insertion causes the latch elements 411 to engage the latch lock cavity 403, thereby mechanically securing the slave plate 408 to the master plate 401. Simultaneously, the pogo pins 410 establish electrical contact with the connector port 407, enabling data and power transmission. Detachment is achieved by actuating the latch release buttons 413, thereby disengaging the latch elements 411 and allowing separation of the plates. The coupling mechanism operates entirely via passive mechanical interaction, with no reliance on active pneumatic, electromagnetic, or motorised actuation. Engagement and disengagement are achieved through controlled robotic positioning and mechanical interaction, including a predefined rotational or translational motion executed by the robotic arm. This passive configuration enhances system reliability, reduces maintenance complexity, and eliminates failure modes associated with active coupling systems.
[0281]
[0292] Advantageously, the passive dynamic end-effector exchange coupling 400 illustrated in Figure 6 provides a mechanically robust, self-aligning, and electrically integrated interface that enables rapid and reliable tool exchange without active actuation. The use of precision alignment pins, inverse-profile latch engagement, and spring-loaded electrical contacts ensures repeatable coupling accuracy, minimizes mechanical wear, and supports continuous autonomous operation in clinical environments.

During post-scan hygiene, a robotic arm retrieves a cleaner endeffector, actuates the towel bin cover 517, and acquires a disposable towel 515 via electromagnetic pickup. The robotic arm then performs cleaning of the biologicalsurface and deposits the used towel into the waste bin 509 via the chute 519, triggering the auto-cover 518. The ultrasound probe end-effector 501 is subsequently docked into the sanitisation tub 504, where automated cleaning is performed using fluid supplied from the storage tank 508 via plumbing 505. The subsystem 500 operates in coordination with the localised edge-processing module and robotic manipulation assembly, forming an integrated hygiene loop. Advantageously, the automated hygiene and consumable replenishment subsystem 500 illustrated in Figure 7 provides a fully integrated, closed-loop hygiene architecture that enables autonomous management of cleaning, waste disposal, and consumable replenishment without human intervention. This configuration ensures consistent clinical hygiene standards, reduces operator workload, and enables deployment of the system 100 in remote or resource-limited environments where trained personnel may not be available.
