No
The description focuses on the hardware components and signal conversion process of the detector, with no mention of AI/ML algorithms for image processing or analysis.
No
The device is described as a detector used for screening and diagnostic mammography, which involves imaging for diagnosis rather than directly treating a condition.
Yes
The "Intended Use / Indications for Use" section explicitly states that "The RSM 2430C is a detector indicated for use in screening and diagnostic mammography." The term "diagnostic mammography" clearly indicates a diagnostic purpose.
No
The device description clearly outlines hardware components like a detector panel, scintillator layer, PIN diode, and thin film transistor, indicating it is a physical device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "screening and diagnostic mammography." This involves imaging the breast using X-rays to detect abnormalities. This is an in vivo (within the living body) diagnostic procedure, not an in vitro (outside the living body) test.
- Device Description: The device is described as an X-ray detector that converts X-ray photons into an electrical signal to create an image. This is consistent with an imaging device used directly on a patient.
- Input Imaging Modality: The input is X-ray, which is an imaging modality used on living subjects.
- Anatomical Site: The anatomical site is the breast, which is part of the living body.
IVD devices are typically used to examine specimens (like blood, urine, tissue) taken from the body to diagnose diseases or conditions. This device is used to directly image the body itself.

Device Description
The RSM 2430C detector panel is an indirect conversion device in the form of a square plate in which the input x-ray photons are absorbed in an x-ray sensitive scintillator layer. The energy of the incoming photons generates light distribution in the scintillator layer. Light is converted to a modulated electrical signal through PIN diode within the pixel of the thin film transistor. The amplified signal is converted to a voltage signal and is then converted from an analog to digital signal which can be transmitted to a viewed image print out, transmitted to remote viewing or stored as an electronic data file for later viewing.

12. Conclusion [21 CFR 807.92(b)(3)]
The RSM 2430C is substantially equivalent to the currently marketed and predicate device (RSM 1824C(K162670) in terms of design features, fundamental scientific technology, indications for use, and safety and effectiveness.
Additionally, substantial equivalence was demonstrated through the non-clinical performance in compliance with the requirements specified in the international and FDA recognized consensus standards, AAMI ANSI ES60601-1, IEC 60601-1-2, ISO 14971, IEC 62220-1 and NEMA PS 3.1 -3.20. Also, substantial equivalence was demonstrated through a clinical test, which was conducted in compliance with the requirements specified in the "CDRH's Guidance for Industry and FDA Staff -Class II Special Controls Guidance Document: Full Field Digital Mammography System".
The results of these tests demonstrate that the subject device (RMS 2430C) meets the acceptance criteria, and the device is adequate for its intended use. The comparison of technological characteristics, non-clinical performance data, safety testing, and clinical image concurrence data demonstrate that the device is as safe and effectiveness.
