The MOZART® Supra® Specimen Tomosynthesis System is a cabinet X-ray system that is used to provide 2-dimensional and 3-dimensional tomographic digital X-ray images of harvested specimens from various anatomical regions.
Device Description
The MOZART SUPRA (XPERT84) Specimen Radiography System is a Cabinet X-ray System specifically designed to provide high detail radiographic imaging of surgically excised medical specimens both in two-dimensional and three-dimensional tomosynthesis views. - It is the only cabinet specimen imaging system to utilize 3-D Tomosynthesis technology. - Creates images in 1mm digital slices of the specimen, allowing physicians to evaluate the specimen layer by layer. Tomosynthesis is an advanced radiographic application that produces individual coronal "slice" images through an anatomical region of inters (ROI). To produce these slices multiple projection radiographic images are acquired in rapid succession as the X-ray tube sweeps and rotates across the ROI. Once acquired, these projection images are subject to image processing that registers and reconstructs them into individual tomographic slices. Tomosynthesis provides visualization of human anatomy by - 1. Removing overlying anatomical structures, which could otherwise obscure a structure of interest by superimposition in a two dimensional presentation, and - 2. Producing a number of slice images throughout the entire volume of the anatomy The exceptionally high magnification capability (up to 5X) from the 0.02 mm focal spot with optimized cabinet geometry and the superior contrast available from the low kV capability provides enhanced film and/or digital imaging performance. This device supports radiographic film sizes up to 30 x 35 cm and can be configured to acquire high resolution, DICOM compliant, digital x-ray images through the use of an integrated camera and Kubtec DIGICOM Specimen Radiography software. To support the Tomosynthesis application, the predicate device, MOZART SUPRA (XPERT84), K200756, has a low-voltage screw drive linear actuator installed in the enclosed head of the cabinet with the same 50 kVp monoblock X-ray tube as the predicate to allow motion of the X-ray source to capture the multiple projection images and an Amorphous Selenium detector mounted stationary in the bottom of the cabinet xray unit
More Information

No
The document describes image processing for tomographic reconstruction but does not mention AI or ML.

No.
This device is an imaging system designed to provide high-detail radiographic images of surgically excised medical specimens, which is a diagnostic rather than a therapeutic function.

No

The device is used to provide X-ray images of harvested specimens, which are then evaluated by physicians. It generates images for evaluation, but does not autonomously provide a diagnosis.

No

The device is a cabinet X-ray system, which is a hardware device. While it includes software for image processing and reconstruction, it is not solely software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to provide X-ray images of harvested specimens. This is an imaging device used to visualize the physical structure of the specimen.
  • Device Description: The description focuses on the X-ray technology, image acquisition, and image processing to create visual representations of the specimen.
  • Lack of IVD Characteristics: An IVD device is typically used to examine specimens in vitro (outside the body) to provide information about a patient's health status, disease, or condition. This often involves analyzing biological markers, chemical substances, or cellular components. The MOZART Supra system does not perform these types of analyses. It provides images, which are then interpreted by a healthcare professional.

The device is a medical imaging system for specimens, not a diagnostic test performed on the specimen itself to determine a medical condition.

II. DEVICE DESCRIPTION

The MOZART SUPRA (XPERT84) Specimen Radiography System is a Cabinet X-ray System specifically designed to provide high detail radiographic imaging of surgically excised medical specimens both in two-dimensional and three-dimensional tomosynthesis views.

  • It is the only cabinet specimen imaging system to utilize 3-D Tomosynthesis technology.
  • Creates images in 1mm digital slices of the specimen, allowing physicians to ● evaluate the specimen layer by layer.

Tomosynthesis is an advanced radiographic application that produces individual coronal "slice" images through an anatomical region of inters (ROI). To produce these slices multiple projection radiographic images are acquired in rapid succession as the X-ray tube sweeps and rotates across the ROI. Once acquired, these projection images are subject to image processing that registers and reconstructs them into individual tomographic slices.

Tomosynthesis provides visualization of human anatomy by

    1. Removing overlying anatomical structures, which could otherwise obscure a structure of interest by superimposition in a two dimensional presentation, and
    1. Producing a number of slice images throughout the entire volume of the anatomy

The exceptionally high magnification capability (up to 5X) from the 0.02 mm focal spot with optimized cabinet geometry and the superior contrast available from the low kV capability provides enhanced film and/or digital imaging performance. This device supports radiographic film sizes up to 30 x 35 cm and can be configured to acquire high resolution, DICOM compliant, digital x-ray images through the use of an integrated camera and Kubtec DIGICOM Specimen Radiography software.

To support the Tomosynthesis application, the predicate device, MOZART SUPRA (XPERT84), K200756, has a low-voltage screw drive linear actuator installed in the enclosed head of the cabinet with the same 50 kVp monoblock X-ray tube as the predicate to allow motion of the X-ray source to capture the multiple projection images and an Amorphous Selenium detector mounted stationary in the bottom of the cabinet xray unit

IV. BASIS FOR THE SUBMISSION

The XPERT 84 Specimen Radiography System is a fully shielded Cabinet X-ray System that has been designed to comply with 21 CFR 1020.40. The system allows more than 20 times geometric magnification of excised specimens with minimal geometric distortion through the use of a focal spot size that is less than 20 microns. The x-ray coverage of the device allows the use of radiographic film sizes up to 35 x 43 cm. The device can also be configured to provide high resolution, DICOM compliant, digital images through the use of an integrated digital camera and Kubtec DIGICOM Specimen Radiography software. The Kubtec DIGICOM Software supports the DICOM Store, Print and Modality Worklist functionalities.

This device, MOZART SUPRA (XPERT84) will include a modification/replacement of the detectors in previously approved devices and functionally identical to the predicate devices. (See specifications in Section V) CMOS detector to an Amorphous SILICON detector

Both systems produce digital images which can be sent to hardcopy printers, softcopy diagnostic workstations and/or stored in archive.

The proposed MOZART SUPRA(XPERT84) Specimen Radiography System, utilizes the predicate devices, MOZART SUPRA(XPERT84) Specimen Radiography System, with the same 90 kVp monobloc X-ray tube installed in the enclosed head of the cabinet as the predicate and both the Hologic TRIDENT(Predicate 2) and the proposed XPERT 84 Specimen Radiography System utilizes the Amorphous Selenium detector mounted stationary in the bottom replacing the predicate CMOS detector of the same shielded cabinet x-ray unit with proprietary software installed into an off the shelf personal computer, Microsoft Windows 10 Operating System, and a 2 megapixel or greater portrait type monitor.

The performance of the proposed AXS-2430V2 detector has been verified and cleared via 510k K193166 as incorporated into the Siemens MAMMOMAT Revelation.

Both systems utilize the same DIGICOM software.

The "Level of Concern" of MOZART SUPRA (XPERT 84) Specimen Radiography System software (DIGICOM) is "moderate"
