The document describes a standard digital mammography system and its components, focusing on image acquisition and basic processing. There is no mention of AI, ML, or related concepts like deep learning, nor are there descriptions of algorithms that would typically employ these technologies for image analysis or interpretation. The performance studies focus on image quality evaluation by radiologists, not on the performance of an AI/ML algorithm.
No
The device is described as an imaging system for screening and diagnosis of breast cancer, which are diagnostic purposes, not therapeutic.
Yes
The device "is indicated for generating mammographic images that can be used for screening and diagnosis of breast cancer."
No
The device description explicitly lists multiple hardware components such as the Operation Panel/Console, X-ray tube, Column and Gantry, and Flat Panel Detector, indicating it is a physical system, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Digimamo D is a medical imaging system that produces X-ray images of the breast. It does not analyze samples taken from the body.
- Intended Use: The intended use is to generate images for screening and diagnosis of breast cancer, which is a function of medical imaging, not in vitro testing.
The device description, input imaging modality (planar digital x-ray images), and anatomical site (entire breast) all confirm that this is an imaging device, not an IVD.

Device Description
This is a mammography system available in only a digital version. The main characteristics are:
Operation Panel/Console: Natively, the Digimamo D Generator operation panel is integrated into the imaging system so that all indications and technical selections for radiographic exposure will be shown on the monitor, in conjunction with the image acquired.
X-ray tube information: The X Radiation Emitters (Target) are available in Tungsten.
Filter Selection:
- Tungsten Target: For radiation beam filter selection, there is a choice of Silver (50μm) or rhodium (50um) filters, use the key to select the desired filter.
- Molybdenum Target: For radiation beam filter selection, there is a choice of Molybdenum (30μm) or rhodium (25μm) filters, use the key to select the desired filter.
The type in use is indicated on the operation panel, and there is the option of automatic selection based on kV.
Window Material and thickness: 0.5mm Be
Focal Spot Sizes: Small focus: 0,1mm, Large Focus: 0,3mm
Operating principle: The general sequence of events in the patient examination procedure and the flow of image data from detector to the final image: (This operating principle is identical to the predicate) -
- User turns on the power.
-
- User turns on the collimation light.
-
- Patient is positioned.
-
- Breast compression is done.
-
- Operator initiates the exposure.
- Initiation of the exposure turns on the x-ray source and the digital image panel acquires the x-ray and breast is decompressed.
- Image is converted by the panel to digital image format, which in turn is transferred to the internal processor for storage and subsequent display.

The kV is selected by the operator. Manual mode: The kV and the mAs are selected by the operator. The density selection: Adjustable in 11 levels (from-5 to + 5) being the default density (0). Adjustments are made directly to the Control Panel.
All control is accomplished through a CPU (workstation) integral part of Digimamo D.
Column and Gantry: The column and arm tube Assembly of Digimamo D, was designed to offer all the comfort and safety in performing mammography exams. Smooth movements with fast and accurate acceleration and deceleration ramps. The control panels located on the right and left sides enable: Position the arm automatically at 45 degrees clockwise and counterclockwise. Rotate the arm left and right (-180 º, 0 º, + 180 º). Move the arm vertically. Select the positioning of the AEC (automatic exposure control). Light the collimator lamp. Select to more or less breast compression stop point. Removable face protector. Informative display. Compression fine adjustment knobs (both sides). Handles for hands (both sides). Emergency button (both sides). Support attachment points for magnification factors of 1.5 and 1.8 times. Bucky/Digital Panel 24x30 cm, equipped with 335 l/pol. anti-diffuser grids and 5:1 ratio in carbon fiber.
Flat Panel Detector: Csl Scintillator, Active area of 291.8 x 233.5 mm, Resolution of 3,840(W) x 3,072(L) pixels, Pixel size: 76 µm. Depth (A/D): 16 bits. Carbon fiber cover.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical testing was required to establish substantial equivalence because of the requirement in the FDA Guidance Document cited above. Sixty images were evaluated by three Board Certified US based radiologists. Images were taken during the standard screening procedure in Fundação Municipal de Saúde de Macaé, Rio de Janeiro, Brazil. Totally, there are 12 sets of images presented in this review. Images were selected in order to represent different categories in density and BIRADS categories. Each set consists of four standard views (right CC, right MLO, left CC, left MLO.) If requested by the radiologist, additional image with magnification was taken. Images were reviewed by US-based MQSA quaified radiologists. The results of clinical image evaluation determined that the clinical images reviewed by the expert radiologists were of sufficiently acceptable quality for mammographic usage.

- The technological characteristics, including design, materials, composition, and energy source, are substantially the same, so there are no issues impacting safety and effectiveness.
-
- Safety and Effectiveness, comparison to predicate device. The results of bench testing AND clinical testing indicate that the new devices are as safe and effective as the predicate device. Proper system operation is fully verified upon installation. We verified that this combination of components worked properly and produced diagnostic quality mammographic images. The key image acquisition component is the RSM2430TD digital x-ray receptor panel (K170930) manufactured by DRTECH. It is electronically identical to the RSM2430C panel cleared in K170930 (different enclosure) with the SAME PRODUCT CODE: MUE.

- Summary of non-clinical testing: Systems were assembled and found to be operating properly. Firmware was validated according to the FDA Guidance: Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices Document issued on: May 11, 2005. We also observed the requirements of this guidance document: Guidance for Industry and FDA Staff Class II Special Controls Guidance Document: Full-Field Diqital Mammoqraphy System Document issued on: November 5, 2010.
Because the system uses Ethernet, we observed the recommendations contained in the FDA Guidance Document: Content of Premarket Submissions for Management of Cybersecurity in Medical Devices Guidance for Industry and Food and Drug Administration Staff. In addition, we reviewed the FDA guidance Pediatric Information for X-ray Imaging Device Premarket Notifications Guidance for Industry and Food and Drug Administration Staff and added a supplement to our user manual. The digital panel software employed was already reviewed by FDA in the reference submission list, above. Labeling is in accordance with the US Performance Standard. This device complies with all applicable requirements of 21 CFR 1020.30, and 1020.31
Digimamo D has been tested by 3rd party Nationally Recognized Testing Laboratories to be in compliance with the following International Standards:
-
IEC 60601-1: 2010 + Aml:2016 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance;
