Intended Use

Clarius AI is intended to semi-automatically place calipers for non-invasive measurements of musculoskeletal structures (e.g., Achilles' tendon, plantar fascia, patellar tendon) on ultrasound data acquired by the Clarius Ultrasound Scanner (i.e., L 7 and L15). The user shall be a healthcare professional trained and qualified in MSK (musculoskeletal) ultrasound. The user shall retain the ultimate responsibility of ascertaining the measurements based on standard practices and clinical iudgment.

Device Story

Clarius AI is a software application integrated into the Clarius Ultrasound Scanner system; it processes real-time ultrasound images of musculoskeletal structures (Achilles' tendon, plantar fascia, patellar tendon). The device uses an AI image segmentation algorithm to identify tendon boundaries; it displays a transparency overlay on the ultrasound image. When imaging is paused, the software calculates the greatest tendon thickness in pixels and automatically places measurement calipers; it outputs the thickness in millimeters. The clinician reviews the output and may manually adjust the calipers. The device is used in clinical settings (hospitals, clinics) by trained healthcare professionals. It assists in clinical management by providing quantitative measurements; the clinician retains ultimate responsibility for clinical decisions. The device benefits patients by providing standardized, semi-automated measurements of musculoskeletal structures.

Clinical Evidence

Bench testing and retrospective analysis only. Training dataset: 20,287 images. Validation study: 73 subjects, 2,503 images. Performance: 96% average Dice score, 94% mean IoU for tendon segmentation. Verification testing compared AI auto-measurements to expert manual measurements; results showed non-inferiority (p=9.0 x 10^-7) with an equivalence margin of 20%. Mean difference between differences was 0.03% (95% CI: -0.05 to -0.01).

Technological Characteristics

Ultrasound image processing software; utilizes non-adaptive machine learning (U-Net with MobileNetV2 backbone). Operates on Clarius Ultrasound App (iOS/Android) using L7 and L15 transducers. Connectivity: Clarius Cloud storage. Standards: IEC 62304 (software lifecycle), ISO 14971 (risk management), NEMA PS 3.1-3.20 (DICOM), IEC 62366-1 (usability).

Indications for Use

Indicated for adult patients; intended for use by trained healthcare professionals to semi-automatically place calipers for non-invasive measurements of musculoskeletal structures (Achilles' tendon, plantar fascia, patellar tendon) on ultrasound data acquired by Clarius L7 and L15 scanners.

Clarius Al (MSK model) is intended for use by trained healthcare practitioners for non-invasive measurements of ultrasound data from musculoskeletal (MSK) ultrasound imaging acquired by the Clarius Ultrasound Scanner system using an artificial intelligence (AI) image segmentation algorithm. Clarius AI (MSK model) is intended to semi-automatically place adjustable calipers and provide supplementary information to the user regarding tendon thickness measurements (i.e., foot/plantar fascia, ankle/Achilles' tendon, knee/patellar tendon). Clarius Al is intended to inform clinical management and is not intended to replace clinical decision-making. The clinician retains the ultimate responsibility of ascertaining the measurements based on standard practices and clinical judgment. Clarius Al is indicated for use in adult patients only. During the ultrasound imaging procedure, the anatomical site is selected through a preset software selection (e.g., foot, ankle, knee), in which the Clarius Al will engage to segment the correlating tendon. Clarius Al analyzes ultrasound images in real-time and outputs probabilities for each pixel within the image for determination of the particular tendon thickness. The combination of all the pixels meeting a programmed threshold will render an overlay being displayed on top of the ultrasound image with a pre-programmed transparency so that the ultrasound greyscale is still visible. Once the user has obtained the best view, imaging can be manually paused, in which the Clarius Al will further analyze the tendon segmentation to determine the greatest thickness, in number of {5}------------------------------------------------ Image /page/5/Picture/0 description: The image shows the Clarius logo.

The user can then manually alter the measurement calipers to make any necessary adjustments if desired. Clarius Al does not perform any functions that could not be accomplished manually by a trained and qualified user. Clarius AI (MSK model) is incorporated into the Clarius App software and is intended for use with the following Clarius Ultrasound Scanner system transducers (previously 510(k)-cleared in K180799, K192107, and K213436): | Clarius Ultrasound Transducers | L7 and L15 | |--------------------------------|---------------------------------------------------------------------------------------------------| | Clarius App Software | Clarius Ultrasound App (Clarius App) for iOS; Clarius Ultrasound App (Clarius App) for Android | ## Indications for Use for Clarius AI (MSK) Clarius AI is intended to semi-automatically place calipers for non-invasive measurements of musculoskeletal structures (e.g., Achilles' tendon, plantar fascia, patellar tendon) on ultrasound data acquired by the Clarius Ultrasound Scanner (i.e., L7 and L15).
