The document describes a standard stationary X-ray system and image acquisition software. There is no mention of AI, ML, or any advanced image processing beyond basic acquisition, storage, communication, display, and processing. The performance studies focus on the hardware components and image quality, not on algorithmic performance metrics typically associated with AI/ML.
No.
The device is described as a diagnostic x-ray system intended for acquiring, storing, communicating, displaying, and processing medical X-ray images, which are used for diagnostic purposes, not therapeutic intervention.
No
The device is an imaging system that acquires, stores, communicates, displays and processes medical X-ray images. It is used by physicians for taking diagnostic x-rays, and the device description explicitly states it is a "diagnostic system intended to generate and control x-rays for examination of various anatomical regions." However, the device itself is not performing a diagnosis; it is providing images that a human expert (qualified/trained physician) then uses for diagnosis. Therefore, it is a diagnostic imaging tool, but not a diagnostic device in the sense of making a diagnosis itself.
No
The device description explicitly states that AcuityUDR "combines components into a complete stationary x-ray system, including tube stand, tube head, collimator, generator, a digital radiography panel, and image acquisition software." This indicates it is a hardware system with integrated software, not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- Device Function: The AcuityUDR is a stationary X-ray system. Its purpose is to acquire, store, communicate, display, and process medical X-ray images of the human body. It does not analyze specimens taken from the body.
- Intended Use: The intended use clearly states it's for taking diagnostic X-rays of adult and pediatric subjects for various anatomical regions. This is an in vivo (within the living body) diagnostic process, not in vitro.
Therefore, the AcuityUDR falls under the category of diagnostic imaging devices, specifically X-ray systems, and not In Vitro Diagnostics.

Device Description
RadmediX AcuityUDR combines components into a complete stationary x-ray system, including tube stand, tube head, collimator, generator, a digital radiography panel, and image acquisition software. 21CFR §892.1680 Identification. A stationary x-ray system is a permanently installed diagnostic system intended to generate and control x-rays for examination of various anatomical regions. This generic type of device may include signal analysis and display equipment supports, comports, component parts, and accessories.
The major component combining these into a complete solution is the tube stand is UL Listed, file number E309191. The tube stands are made to carry the weight of the tube head, collimator, and digital X-ray panels. These tube stands may also have supporting devices such as wall stands, tables, stitching stands, step stools, and chairs. These supporting devices allow for imaging in standing, sitting, and laying positions. The Radmedix Acuity tube stands with supporting devices make a stationary x-ray system allowing for ease of use for the technologist and provides rapid patient care. Similar to the predicate our stationary x-ray system employs a tube stand that is a generic type of device and can use various brands of tube heads, collimators, generators, and digital radiography panels all meeting the cited performance standard.
Radmedix provides a previously cleared digital x-ray detector. The panel enclosure can support other similarly sized detectors.
The previously cleared software supplied with the system is AccuVue (K210919). This medical software communicates with the digital x-ray detector and allows acquisition and processing of x-ray images. This software complies with DICOM standards and can transmit and receive data with a PACS system. The software is configurable to acquire images from various digital radiography panels.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non clinical testing was performed successfully according to IEC 60601-1:2005 + A1:2012 + A2:2020 and 60601-1-2:2014 standards for the changed component (the tube stand). All components subject to the CDRH performance standard are certified to comply. All X-ray components carry an NRTL certification label. The software employed was used unmodified from clearances. Cybersecurity precautions were added to the software users' manuals. Generator User Manuals were updated for Pediatric Considerations.
A complete system was constructed and field tested, acquiring DICOM images from all major body structures, including abdomen, ankle, calcaneus, c-spine ap and c-spine lateral, elbow, foot, knee, hand, lspine ap and l-spine lateral, shoulder, chest, and skull. All images were of high quality and contrast and clinically acceptable. This testing was performed on an AcuityUDR system equipped with a SYFM stand, a Canon E7242FXX tube head, a Collimaire CML-125, a Summit L550-31 generator, and an iRay Technology Taicang Ltd. digital receptor panel. Each new configuration undergoes a digital image integration protocol and a total system validation protocol prior to shipment.
Clinical testing was not required for a determination of substantial equivalence.

All of the components subject to the CDRH performance standard are certified to comply with the standard by their respective manufacturers. We do not supply any non-certified components. All X-ray components (generators, tubes, collimators, and applicable accessories) carry an NRTL certification label (UL, ETL, etc.). The software employed was used unmodified from clearances obtained from FDA. In recognition of possible cybersecurity threats to the software, we consulted this guidance: Content of Premarket Submissions for Management of Cybersecurity in Medical Devices Guidance for Industry and Food and Drug Administration Staff October 2014. As a result, we updated our own internal standard operating procedures and added cybersecurity precautions to the software users' manuals. Generator User Manuals were previously updated to add Pediatric Considerations.
We also constructed and field tested a complete system and acquired DICOM images from all major body structures, including abdomen, ankle, calcaneus, c-spine ap and c-spine lateral, elbow, foot, knee, hand, lspine ap and I-spine lateral, shoulder, chest, and skull. All images were of high quality and contrast and clinically acceptable. This testing was performed on an AcuityUDR system equipped with the following components: Stand, (SYFM), a Canon E7242FXX tube head, a Collimaire CML-125, a Summit L550-31 generator, and an iRay Technology Taicang Ltd. digital receptor panel. Each new configuration undergoes a digital image integration protocol and a total system validation protocol prior to shipment to make sure that the configuration works as intended.
6. Clinical testing
Not required for a determination of substantial equivalence.
7. Substantial Equivalence Discussion.
The RadmediX AcuityUDR performs the same functions using the same technological methods to produce diagnostic x-ray images as the predicate. In all material aspects, the two RadmediX systems are substantially equivalent to each other. The flat-panel detectors used with the x-ray system Acuity present comparable or better performance than the predicate detectors.
