Venue, Venue Go, Venue Fit and Venue Sprint are general-purpose diagnostic ultrasound systems intended for use by qualified and trained healthcare professionals to evaluate the body by ultrasound imaging and fluid flow analysis.
The systems utilize a variety of linear, convex, and phased array transducers which provide high imaging capability, supporting all standard acquisition modes.
The systems have a small footprint that easily fits into tight spaces and positioned to accommodate the sometimes-awkward work settings of the point of care user.
The Venue is a mobile system, the Venue Go and Venue Fit are compact, portable systems that can be hand carried using an integrated handle, placed on a horizontal surface, attached to a mobile cart or mounted on the wall. Venue, Venue Go and Venue Fit have a high-resolution color LCD monitor, with a simple, multi-touch user interface that makes the systems intuitive.
The Venue Sprint is used together with the Vscan Air probes and provides the user interface for control of the probes and the needed software functionality for analysis of the ultrasound images and saving/storage of the related images and videos.
The Venue, Venue Go, Venue Fit and Venue Sprint systems can be powered through an electrical wall outlet for long term use or from an internal battery for a short time with full functionality and scanning. A barcode reader and RFID scanner are available as additional input devices. The systems meet DICOM requirements to support users image storage and archiving needs and allows for output to printing devices.
The Venue, Venue Go and Venue Fit systems are capable of displaying the patient's ECG trace synchronized to the scanned image. This allows the user to view an image from a specific time of the ECG signal which is used as an input for gating during scanning. The ECG signal can be input directly from the patient or as an output from an ECG monitoring device. ECG information is not intended for monitoring or diagnosis. Compatible biopsy kits can be used for needle-guidance procedures.
The provided document, a 510(k) Clearance Letter and Submission Summary, primarily focuses on the substantial equivalence of the GE Healthcare Venue series of diagnostic ultrasound systems to previously cleared predicate devices. It specifically details the "Auto Bladder Volume (ABV)" feature as an AI-powered component and provides a summary of its testing.
Here's a breakdown of the acceptance criteria and the study proving the device meets them, based only on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance (for Auto Bladder Volume - ABV)
| Acceptance Criteria | Reported Device Performance |
|---|---|
| At least 90% success rate in automatic caliper placement for bladder volume measurements when bladder wall is entirely visualized. | Automatic caliper placement success rate: 95.09% (with a 95% confidence level) |
| Performance demonstrated consistent across key subgroups including subjects with known BMI (healthy weight, obese, overweight). | Healthy weight (18.5-24.9): 95.64% |
| Obese (25-29.9): 95.59% | |
| Overweight (Over 30): 92.6% |
2. Sample Size Used for the Test Set and Data Provenance
- Test Set (Verification Dataset) Sample Size: 1874 images from 101 individuals.
- Data Provenance:
- Country of Origin: USA and Israel.
- Retrospective or Prospective: Not explicitly stated as either retrospective or prospective. However, the description of "data collected from several different Console variants" for training and verification suggests pre-existing data, which often leans towards a retrospective collection.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- Number of Experts: Not explicitly stated. The document refers to "annotators" who performed manual annotation.
- Qualifications of Experts: Not explicitly stated. The annotators are described as performing "manual annotation," implying they are skilled in this task, but specific qualifications (e.g., radiologists, sonographers, years of experience) are not provided.
4. Adjudication Method for the Test Set
- Adjudication Method: Not explicitly stated. The document mentions "annotators performed manual annotation," but does not detail if multiple annotators were used for each case or any specific adjudication process (e.g., 2+1, 3+1 consensus).
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- Was an MRMC study done? No. The document states: "The subjects of this premarket submission, Venue, Venue Go, Venue Fit and Venue Sprint, did not require clinical studies to support substantial equivalence." The testing described for ABV is a standalone algorithm performance validation against established ground truth, not a comparative human-AI study.
- Effect Size of Human Readers Improvement: Not applicable, as no MRMC study was performed.
6. Standalone (Algorithm Only) Performance Study
- Was a standalone study done? Yes. The "AI Summary of Testing" section describes a study for the Auto Bladder Volume (ABV) feature, which assesses the algorithm's "automatic caliper placement success rate" against manually established ground truth. This is a standalone performance evaluation of the algorithm.
7. Type of Ground Truth Used (for ABV Test Set)
- Ground Truth Type: Expert consensus/manual annotation. The document states: "Ground truth annotations of the verification dataset were obtained as follows: In all Training/Validation and Verification datasets, annotators performed manual annotation on images converted from DICOM files." They identified "landmarks, which represent the bladder edges," corresponding to standard measurement locations.
8. Sample Size for the Training Set (for ABV)
- Training Set Sample Size: Total dataset included 8,392 images from 496 individuals. Of these, 1,874 were used for the verification dataset, and "the rest" were used for training/validation. This implies the training/validation set would be 8392 - 1874 = 6518 images from the remaining individuals not included in the verification set.
9. How the Ground Truth for the Training Set Was Established (for ABV)
- Ground Truth Establishment: Similar to the verification dataset, "annotators performed manual annotation on images converted from DICOM files" for both Training/Validation and Verification datasets. They chose "4-6 images that represent different bladder volume status" for each individual and annotated "4 different landmarks" per view (transverse and longitudinal) representing bladder edges.
