Vscan Air is a battery-operated software-based general-purpose ultrasound imaging system for use by qualified and trained healthcare professionals or practitioners that are legally authorized or licensed by law in the country, state or other local municipality in which he or she practices. The users may or may not be working under supervision or authority of a physician. Users may also include medical students working under the supervision or authority of a physician during their education / training. The device is enabling visualization and measurement of anatomical structures and fluid including blood flow.
Vscan Air's pocket-sized portability and simplified user interface enables integration into training sessions and examinations in professional healthcare facilities (ex. Hospital, clinic, medical office), home environment, road/air ambulance and other environments as described in the user manual. The information can be used for basic/focused assessments and adjunctively with other medical data for clinical diagnosis purposes during routine, periodic follow-up, and triage.
Vscan Air supports black/white (B-mode), color flow (Color Doppler mode, M-mode, M-mode, combined (B + Color Doppler) and Harmonic Imaging modes with curved, linear and sector array transducers.
With the curved array transducer of the dual headed probe solution, the specific clinical applications and exam types include: abdominal, fetal/obstetrics, gynecological, urology, thoracic/lung, cardiac (adult and pediatio, 40 kg and above), vascular/peripheral vascular, musculoskeletal (conventional guidance (includes free hand needle/catheter placement, fluid drainage, nerve block and biopsy).
With the linear array transducer of the dual headed probe solution, the specific clinical applications and exam types include: vascular/peripheral vascular, musculoskeletal (conventional and superficial), small organs, thoraciclung, ophthalmic, pediatics, neonatal cephalic, interventional guidance (includes free hand needle/catheter placement, fluid drainage, nerve block, vascular access and biopsy).
With the sector array transducer of the dual headed probe solution, the specific clinical applications and exam types include: cardiac (adult and pediatic, 40 kg and above), abdominal, fetal/obstetnes, gynecological, urology, thoracic/ lung, pediatics, adult cephalic, interventional guidance (includes free hand needle/catheter placement, fluid drainage, nerve block and biopsy).
Vscan Air™ is a battery-operated general-purpose diagnostic ultrasound imaging system for use by qualified and trained healthcare professionals. It enables ultrasound imaging guidance, visualization and measurement of anatomical structures and fluid.
Vscan Air consists of an app which can be installed on Android™ or iOS devices, and 2 probes which use wireless technology for communication.
Its pocket-sized portability and simplified user interface enable integration into training sessions and examinations in professional healthcare facilities (ex. Hospital, clinic, medical office), home environment, road/air ambulance and in other environments. The information can be used for basic/focused assessments and adjunctively with other medical data for clinical diagnosis purposes during routine, periodic follow-up, and triage assessments for adult, pediatric and neonatal patients. Vscan Air can also be useful for interventional guidance.
The provided text is a 510(k) Summary for the GE Medical Systems Ultrasound and Primary Care Diagnostics Vscan Air, outlining its substantial equivalence to predicate devices. It does not contain information on specific acceptance criteria and the detailed study results that prove the device meets these criteria in terms of clinical performance (e.g., accuracy, sensitivity, specificity) for a particular AI function.
The document primarily focuses on:
- Regulatory information: Device name, regulation, product codes, predicate devices.
- Intended Use/Indications for Use: Describes the general applications of the ultrasound system.
- Technological comparison: Explains how the Vscan Air is similar to its predicate and reference devices in terms of technology, modes, transducers, and software features.
- Non-Clinical Tests: Mentions evaluation for acoustic output, biocompatibility, cleaning/disinfection, and electrical/electromagnetic/mechanical safety, and adherence to various safety standards.
- Absence of Clinical Studies: Explicitly states, "The subject of this premarket submission, Vscan Air, did not require clinical studies to support substantial equivalence."
Therefore, based on the provided input, I cannot fulfill the request for:
- A table of acceptance criteria and reported device performance (for clinical/AI performance).
- Sample size used for the test set and data provenance.
- Number of experts and their qualifications for ground truth.
- Adjudication method for the test set.
- MRMC study details or effect size.
- Standalone performance details.
- Type of ground truth used.
- Sample size for the training set.
- How ground truth for the training set was established.
The document confirms that this particular submission for Vscan Air did not require clinical studies, implying that the performance evaluation relied on non-clinical testing and comparison to predicate devices, rather than a prospective clinical trial with a defined test set and established ground truth for an AI algorithm.

Dear Lee Bush:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
