Patent number: 11504095Abstract: The position and orientation of an ultrasound probe is tracked in three dimensions to provide highly-accurate three-dimensional bone surface images that can be used for anatomical assessment and/or procedure guidance. The position and orientation of a therapy applicator can be tracked in three dimensions to provide feedback to align the projected path of the therapy applicator with a desired path for the therapy applicator or to provide feedback to align the potential therapy field of a therapy applicator with a target anatomical site. The three-dimensional bone surface images can be fit to a three-dimensional model of the anatomical site to provide or display additional information to the user to improve the accuracy of the anatomical assessment and/or procedure guidance.Type: GrantFiled: January 8, 2019Date of Patent: November 22, 2022Assignee: Rivanna Medical, Inc.Inventors: Frank William Mauldin, Adam Dixon, Kevin Owen

Patent number: 11147536Abstract: Handheld ultrasound imaging devices for identification of target regions are generally described. Medical ultrasound is a popular medical imaging modality primarily used for diagnostic imaging of soft tissue but also for interventional procedures such as guidance of a needle or catheter placement. Examples include diagnostic imaging of organs, such cardiac or liver structures. Common interventional procedures that rely on ultrasound guidance are central line placement and guidance of nerve blocks, both of which are high volume procedures in certain hospital settings such as the intensive care unit (ICU). Handheld ultrasound imaging devices with integral display screens and improve portability are described, along with systems and methods for orienting displayed ultrasound images so as to improve their usefulness in guiding interventional procedures.Type: GrantFiled: January 10, 2018Date of Patent: October 19, 2021Assignee: Rivanna Medical LLCInventors: Frank William Mauldin, Jr., Kevin Owen, Adam Dixon

Publication number: 20210085291Abstract: A scan head is described which permits movement of a scanning element such as a transducer or transducer array within the head. A position sensor is employed such as an inductive position sensor. Various embodiments allow for low-volume low-cost scan heads that can be used in applications such as medical imaging, industrial applications or other uses, and may be employed with ultrasound imaging transducers, arrays or other types of elements integrated into said scan head. Movement of the transducers or other elements in the scan head permit a wider operational field including to sweep a larger imaging region and/or to extend the effective operation of the unit into greater dimensions along one or more degrees of freedom.Type: ApplicationFiled: September 25, 2020Publication date: March 25, 2021Applicant: Rivanna Medical LLCInventors: Adam Dixon, Frank William Mauldin, Kevin Owen

Publication number: 20190209119Abstract: An ultrasound imaging device includes an angle sensor to measure the angular orientation of the device. A first user input causes the device to store the first angular orientation in memory as a stored angular orientation. A second user input causes the device to determine a second angular orientation of the device or of a projected path of a probe through a probe guide. The device compares the second angular orientation with the first angular orientation and provides a visual indication of the direction(s) to rotate the device and/or probe holder and/or probe so that the second angular orientation is equal to or substantially equal to the stored angular orientation.Type: ApplicationFiled: January 8, 2018Publication date: July 11, 2019Inventors: Frank William Mauldin, JR., Adam Dixon, Kevin Owen
