Accuro XV Ultrasound Imaging System for BoneEnhance and Fracture Detection Algorithms

October 13, 2026 updated by: Rivanna Medical, Inc.

MSK Injury Assessment Imaging System: Feasibility and Data Acquisition for Algorithm Development and Testing

The Accuro XV is a cart-based, bedside ultrasound instrument that incorporates new signal processing-based technologies for enhanced bone and soft-tissue imaging.

Patients presenting to the Study Setting (e.g., Emergency Departments, urgent care centers, orthopedic clinics, radiology departments, and other clinical environments with access to standard-of-care (SOC) imaging with a suspected distal extremity injury (wrist, forearm, ankle, or lower leg) who have undergone SOC imaging during their clinical evaluation, will be enrolled for additional extremity imaging with the Accuro XV.

In this feasibility study, investigators will assess the safety of Accuro XV by review of any adverse events (AEs) and by comparing the comfort level of patients during Accuro XV image capture and standard-of-care imaging. Investigators will retrospectively assess image quality by reviewing all images captured to ensure the image is clear of artifact and other visual imperfections. The de-identified imaging data will then be used for algorithm development and testing. This data will help to verify plans for future study protocols and help to ensure the device is optimized for its clinical use prior to further clinical studies. The results will also be used as an input to RIVANNA's usability and human factors engineering process per IEC 60601-1-6 as recognized by FDA.

The Accuro XV is investigational in this study and is not intended to guide clinical decision-making.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Experimental: Accuro XV Imaging

Participants with a distal extremity injury who have undergone standard-of-care imaging will receive additional imaging with the Accuro XV ultrasound imaging system. Accuro XV imaging will be performed after completion of standard-of-care clinical imaging and will not be used for clinical decision-making or patient management. Imaging data collected during the study will be used to evaluate device feasibility, safety, image quality, and to support the development and testing of future algorithms.
Device: Accuro XV Ultrasound Imaging System

The Accuro XV Ultrasound Imaging System is a cart-based ultrasound imaging device designed to acquire volumetric images of bone and soft tissue anatomy of the distal extremities. In this study, participants will undergo additional Accuro XV imaging following standard-of-care imaging for a distal extremity injury. The imaging procedure includes acquisition of multiple views of the injured anatomy using ultrasound technology and advanced image-processing methods to generate three-dimensional representations of bone and soft tissue structures. Images collected during the study will be used to evaluate device feasibility, safety, image quality, and to support the development and testing of future algorithms. Accuro XV imaging results will not be used for clinical decision-making.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Accuro XV Image Quality Assessment
Time Frame: From Accuro XV image acquisition through completion of retrospective image-quality assessment, up to 48 months.

Retrospective assessment of acquired Accuro XV images for artifacts and other visual imperfections to evaluate image quality and suitability for subsequent analysis and algorithm development.
From Accuro XV image acquisition through completion of retrospective image-quality assessment, up to 48 months.
Feasibility of Accuro XV Imaging Acquisition
Time Frame: During and immediately after Accuro XV imaging on the day of enrollment.

Successful acquisition of Accuro XV images of the target distal extremity anatomy according to study procedures; site PIs, AIs, and other Accuro XV users will be queried on how Accuro XV fits into their clinical workflow in terms of usability, maneuverablity, reliability and more. Surveys to be developed.
During and immediately after Accuro XV imaging on the day of enrollment.
Participant Comfort During Imaging
Time Frame: Immediately after Accuro XV imaging on the day of enrollment.

Participant-reported comfort and pain scores associated with Accuro XV imaging collected through the participant questionnaire. Participants completed a questionnaire assessing pain associated with both standard-of-care imaging and Accuro XV scanning. Specifically, participants were asked to rate their pain (1) before standard-of-care imaging, (2) during standard-of-care imaging, (3) before Accuro XV scans, and (4) during Accuro XV scans. Pain was measured using an 11-point Likert-type scale ranging from 0 ("none") to 10 ("severe"), with higher scores indicating greater pain.
Immediately after Accuro XV imaging on the day of enrollment.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Likert-Type Scale Participant-reported Imaging Modality Preference
Time Frame: Immediately after Accuro XV imaging on the day of enrollment.

Participant-reported preference between Accuro XV imaging and standard-of-care imaging modalities. Participants completed a questionnaire assessing satisfaction with both standard-of-care imaging and Accuro XV scanning. Participants were asked to rate their satisfaction with each imaging modality on an 11-point Likert-type scale ranging from 0 ("not satisfied at all") to 10 ("very satisfied"), with higher scores indicating greater satisfaction. In addition, participants were asked to indicate their preferred imaging modality by selecting either Accuro XV, standard-of-care imaging, or no preference.
Immediately after Accuro XV imaging on the day of enrollment.
