The provided text describes a 510(k) premarket notification for the Morpheus® RealTime Ultrasound, Pathway® RealTime Ultrasound, and QuickScan® Bladder Ultrasound systems. It asserts their substantial equivalence to a predicate device, the Interson USB Ultrasound Probe System (K070907). The document focuses on demonstrating this equivalence rather than presenting an independent study with new acceptance criteria and performance data for the device. Therefore, a direct table of acceptance criteria and reported device performance with specific values cannot be compiled from the provided text as the application relies on the predicate's established performance.

However, based on the provided text, we can infer the basis for acceptance and the type of study conducted to demonstrate this.

Here’s a breakdown of the requested information, derived from the document's content:

1. A table of acceptance criteria and the reported device performance

The provided document does not list specific, quantitative acceptance criteria for the subject devices, nor does it present new performance data for them. Instead, the acceptance criterion is substantial equivalence to an existing predicate device (Interson USB Ultrasound Probe System, K070907). The reported device performance is implicitly considered to be equivalent to that of the predicate device based on similar technological characteristics and a subset of clinical applications.

• Same technological characteristics (materials, measurements, principle of operation, transducer probe design, acoustic output limits).
• Same intended use (Diagnostic ultrasound imaging or fluid flow analysis of the human body for specified clinical applications).
• Similar safety and effectiveness features. | Morpheus® RealTime Ultrasound, Pathway® RealTime Ultrasound, QuickScan® Bladder Ultrasound:
• Materials: TPX brand Polymethyle Pentene (PMP) for lens; Ertalyte brand Polyetheylene Terephthalate (PET-P), Delrin for housing. (Identical to predicate)
• Measurements: Distance (mm), Circumference (mm), Area (mm²), Angle (degree). (Identical to predicate)
• Principle of Operation: Apply high voltage bursts to Piezoelectric material in the transducer and detect the reflected echo to construct 2D images for diagnostic purposes. (Identical to predicate)
• Transducer Probe Design: Mechanical sector ultrasound imaging probe that connects directly to host computer via USB. Host computer forms real-time ultrasonic images without additional electronics. (Identical to predicate)
• Acoustic Output Limits: SPTA.3 94 mW/cm² (Max), MI 1.9 (Max). (Identical to predicate)
• Clinical Applications: Subset of predicate's applications (Abdomen, OB/GYN, Urology). (Considered safe and effective as they are within the predicate's cleared range).
• Report:
  • Morpheus®/Pathway®: Multiple page report displaying up to 10 user selectable images, user notes, printed on standard 8 1/2" X 11" paper. (Enhanced functionality compared to predicate, but the underlying images and data are the same).
  • QuickScan®: Single page report displaying a single image, printed on 80mm thermal printer paper. (Condensed report compared to predicate, but underlying data is the same). |

2. Sample size used for the test set and the data provenance

No new test set or data provenance details are reported for the subject device. The submission relies on the existing clearance of the predicate device (Interson USB Ultrasound Probe System, K070907). The specific studies and data used for the predicate device's clearance are not detailed in this document.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. No new test set or ground truth establishment process is described for the subject device. The substantial equivalence argument relies on the predicate device's prior clearance.

4. Adjudication method for the test set

Not applicable. No new test set or adjudication method is described.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This device is an ultrasound imaging system, not an AI-assisted diagnostic tool to improve human reader performance. No MRMC study was conducted or referenced for the subject device.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. The device is a diagnostic ultrasound system intended for use by a human operator, not an autonomous algorithm. The document emphasizes that the device functions identically to the predicate in how it generates images.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The type of ground truth for verifying the performance of the predicate device (and therefore implicitly the subject device) for diagnostic ultrasound imaging would typically involve comparison to other established imaging modalities, clinical findings, or expert interpretation. However, the current document does not specify the ground truth used for the predicate's original clearance.

8. The sample size for the training set

Not applicable. This document describes an ultrasound imaging device, not an AI/machine learning system that requires a training set.

9. How the ground truth for the training set was established

Not applicable, as there is no training set for this type of device.
