Technical University of Munich developed in conjunction with Zhejiang University and Johns Hopkins University a new vision-based robotic 3D ultrasound system powered by Cephasonics to create accurate 3D scans even if the target limb changes position after the scan begins.
While 2D ultrasound imaging can provide images in real time even if the target moves, 3D ultrasound imaging is much more sensitive to changes in movement. Repositioning limbs, for example, may be necessary to make different parts of a limb available to the ultrasound probe in order to image an entire artery. The angle of the 2D image changes from its original position, making it difficult to stitch the images together into a 3D representation.
Robotic ultrasound systems (RUSS) produce high quality images by precisely controlling the contact force and orientation of the ultrasound probe. Combining robot arms with depth cameras to determine optimal probe position increases the accuracy of the scan. This is still not effective for 3D imaging because this system also cannot account for movement of the scan target.
The new system developed by the researchers, as described in the paper titled “Motion-Aware Robotic 3D Ultrasound” (bit.ly/VSD-MTN3D), combines RUSS with depth cameras to make 3D imaging with ultrasound possible. The system uses a LBR iiwa 14 R820 robot arm from Kuka (Augsburg, Germany; www.kuka.com/en-us), a Cicada LX ultrasound machine from Cephasonics Ultrasound (Santa Clara, CA, USA; www.cephasonics.com), and an Azure Kinect 3D camera from Microsoft (Redmond, WA, USA; www.microsoft.com/en-us).
The process begins by drawing a red line on the patient’s skin to mark the path of the ultrasonic probe during the scan. The Kinect camera images the line, and the software registers the path to calculate a trajectory for the robot arm. Two marker spheres with retroreflective layers are placed on both ends of the drawn red line. The spheres help provide reliable position data for the Kinect camera and aid in extracting region of interest and trajectory data. This helps the system account for limb position adjustment during the scan.
Because the system can assign 3D coordinates to images during the scan, even if the limb moves, the system can compensate for the movement and stitch the images together as if the limb movement never took place. This allows for creating accurate 3D scan data. Testing demonstrated that the system compensates for up to 40° of target rotation.
The researchers proposed that a laser system could project a trajectory onto the surface of a limb and replace the drawn red line. Also, while the system test simulated vascular scans, the system could also perform bone visualization.

Santa Clara, CA March 15, 2020 — Cephasonics, a leader in advanced ultrasound technology and systems, today announced that the United States Patent and Trademark Office (USPTO) has issued a new patent (U.S. Patent No. 10,499,884 ) to Cephasonics Ultrasound for Ultrasound Systems and Methods for Searching for a First Object within a Second Object Using a Dynamic Hardware Scheduler Micro-controller. The invention relates to ultrasound scanning and particularly to ultrasound scanning using a plurality of beams. This expands Cephasonics patent portfolio to 8 for technology used in Cephasonics family of ultrasound development and OEM systems.
Today, most ultrasound systems have limited, fixed functionality and require sophisticated user control. Most ultrasound systems cannot provide multiple simultaneous functions. For example, an operator of a typical ultrasound system is required to be skilled in the operation of the machine and capable of directing beams to the desired bodily objects. As a result, the use of such systems is limited by available human resources. And, even in the case of a skilled person, it might prove a challenge to locate an object on or within another object.
This patent covers Cephasonics technology that enables development of ultrasound systems, which can automatically find and recognize an object such as a tumor or cyst within another object such as an organ in the body without requiring an operator to be skilled in the use of the ultrasound apparatus. This patent extends 3 other patents issued to Cephasonics: A System and Method for Automatically Adjusting Beams to Scan a Desired Object in a Body”, “A Method for Scheduling Events of an Array of Ultrasound Transmitters Using a Timing Wheel”, and “A Dynamic Hardware Schedule Controller.”
Cephasonics CEO, Richard Tobias commented that, “this patent advances our leadership in ultrasound AI-based applications that can locate, recognize and characterize objects within the body.” He also stated that “for our partners who are developing new ultrasound products, this also enhances our Cephasonics platform in helping them create and deliver unique value and dramatically expand where and how ultrasound can be used.”
