The device generates ultrasound images for evaluation of various anatomical sites, which is a key function of diagnostic imaging.
No
The device description explicitly states that the K3900 Ultrasound Imaging System consists of an ultrasound transducer, a processing unit, and a tablet, indicating it is a hardware system with integrated software, not a software-only device.
Based on the provided information, the K3900 Ultrasound Imaging System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
- K3900 Function: The K3900 is an ultrasound imaging system. It uses ultrasonic waves to create images of internal body structures. It does not perform tests on samples taken from the body.
- Intended Use: The intended use clearly states it's for "ultrasound evaluation" of various anatomical sites. This is an imaging modality, not an in vitro diagnostic test.
- Device Description: The description details how the device generates and processes ultrasound data to produce images. There is no mention of analyzing biological samples.
Therefore, the K3900 falls under the category of medical imaging devices, not In Vitro Diagnostics.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Nonclinical Testing Summary: MAUI Imaging has conducted bench performance testing of the K3900 subject device to verify and validate that the device requirements and specifications and to demonstrate that any differences between the subject and predicate device do not raise different questions of safety or effectiveness. Additional testing to support the substantial equivalence between the subject and predicate device includes:
- Evaluation of biocompatibility per ISO 10993-1,
- Electrical safety testing per IEC 60601-1,
- Electromagnetic compatibility per IEC 60601-1-2,
- Performance of the ultrasound safety, controls, and display in accordance with IEC60601-2-37:2015 and IEC 62359: 2017 to demonstrate that the device is within safety limits as well as requirements for a Track 3 ultrasound imaging device per FDA Guidance, "Marketing Clearance of Diagnostic Ultrasound Systems and Transducers", dated February 2023, and
- Human factors usability testing
Clinical Testing Summary: Clinical performance testing was conducted to validate that a healthcare professional would get equivalent imaging from the K3900 subject device as compared to the GE LOGIO E9 predicate device. MAUI collected comparative ultrasound imaging data under an IRB approved study protocol at a radiology clinic where volunteers were recruited. After obtaining informed consent, a radiologist captured ultrasound images from both devices. Side-by-side comparisons of the still images of numerous anatomical structures showed that the imaging from the subject device was substantially equivalent to the predicate.

Device Description [807.92(a)(4)]
The K3900 Ultrasound Imaging System ("K3900") is a Track 3 general purpose ultrasound imaging system. The device generates and collects ultrasonic pulsed echo data via a transducer that is then digitized for further processing. The processing includes beamforming, image processing, and image optimization that then outputs an ultrasound image. This image may be displayed on a tablet or common displays through HDMI for general purpose radiological evaluation. The K3900 consists of an ultrasound transducer, a processing unit that manages the transducer and all data processing, and a tablet that provides the user interface to operate the device, view and analyze the ultrasound dataset, and manage patient study sessions.

510(k) Summary for K230511 MAUI Imaging, K3900 Ultrasound Imaging System
The K3900 utilizes "ping" technology. In contrast to phased array transmission that transmit along predetermined scan lines using a large number of transducer elements with multiple focal regions, a ping is an unfocussed pulse transmitted by a limited set of transducer elements. Since the transmitted pulses are unfocussed, no beamforming or focusing is performed on the transmit side. Beamforming to create the ultrasound image is entirely done on the receive side. i.e., the process of combining the echo information is done by utilizing all of the receiver element data. In the predicate device, the beamforming process is split between the transmit side and the receive side, i.e., part of the beamforming is done by transmitting a focused pulse of ultrasound waves, and additional signal processing is conducted on the received echo data. This is a minor difference in signal processing and both the subject and predicate devices achieve the same imaging results. The differences in beamforming methods, which have been verified and validated through performance testing do not raise different questions of safety or effectiveness and demonstrate substantial equivalence to the predicate device.
Indications for use [807.92(a)(5)]
The K3900 Ultrasound Imaging System is intended for use by a qualified healthcare personnel in environments where healthcare is provided for ultrasound evaluation of Fetal; Abdominal; Pediatric; Small Organ (breast, testes, thyroid); Neonatal Cephalic; Cardiac (adult and pediatric); Peripheral Vascular: Musculo-skeletal Conventional and Superficial; Urology (including prostate); and Intraoperative (abdominal, thoracic and vascular).

- Electromagnetic compatibility per IEC 60601-1-2, ●
- . Performance of the ultrasound safety, controls, and display in accordance with IEC60601-2-37:2015 and IEC 62359: 2017 to demonstrate that the device is within safety limits as well as requirements for a Track 3 ultrasound imaging device per FDA Guidance, "Marketing Clearance of Diagnostic Ultrasound Systems and Transducers", dated February 2023, and
- . Human factors usability testing
Clinical Testing Summary [807.92(b)(2)]
Clinical performance testing was conducted to validate that a healthcare professional would get equivalent imaging from the K3900 subject device as compared to the GE LOGIO E9 predicate device. MAUI collected comparative ultrasound imaging data under an IRB approved study protocol at a radiology clinic where volunteers were recruited. After obtaining informed consent, a radiologist captured ultrasound images from both devices. Side-by-side comparisons of the still images of numerous anatomical structures showed that the imaging from the subject device was substantially equivalent to the predicate.
Conclusions [807.92(b)(3)]
The K3900 has the same intended use, indications for use and similar technological characteristics as the predicate. The minor differences in technological characteristics have been analyzed and addressed through software verification and validation testing. The testing results demonstrate that differences between the subject and predicate device do not raise different questions of safety or effectiveness. Therefore, the K3900 is substantially equivalent to the predicate device
