No
The document mentions "iterative image reconstruction algorithm" but does not explicitly mention AI, ML, or related terms like deep learning or neural networks. The performance studies focus on non-clinical testing and substantial equivalence to a predicate device, without describing training or test sets typically associated with AI/ML development.
No
The device is used for imaging and verification of excised tissue, primarily for diagnosis and procedural efficiency, not for directly treating a disease or condition.
Yes
The device provides digital x-ray images to "provide rapid verification that the correct tissue has been excised during the biopsy procedure," which is a diagnostic purpose.
No
The device description explicitly states it is a "portable, fully shielded cabinet X-ray system" and includes an "image-acquisition device," indicating it is a hardware system with integrated software, not a software-only device.
Based on the provided information, the Volumetric Specimen Imager is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body. They are used to detect diseases, conditions, or infections.
- Device Function: The Volumetric Specimen Imager is a cabinet x-ray system used to image harvested specimens (tissue that has already been removed from the body). Its purpose is to provide rapid verification that the correct tissue has been excised during a biopsy procedure.
- Imaging Modality: It uses X-ray imaging, which is a form of medical imaging, not an in vitro diagnostic test.
- Intended Use: The intended use is to image the physical specimen itself for verification of excision, not to analyze biological markers or characteristics within the specimen for diagnostic purposes in the traditional IVD sense.
While the device is used in relation to a biological specimen, its function is to provide a visual representation of the specimen's physical structure using X-rays, not to perform a diagnostic test on the specimen's biological components.

Intended Use / Indications for Use
The Volumetric Specimen Imager is a Cabinet x-ray system that is used to provide two and three dimensional digital x-ray images of harvested specimens from various anatomical regions in order to provide rapid verification that the correct tissue has been excised during the biopsy procedure. Doing the verification directly in the same room or nearby enables cases to be completed faster, thus limiting the time the patient needs to be under examination. Specimen radiography can potentially limit the number of patient recalls.

Device Description
The Clarix Imaging Volumetric Specimen Imager (VSI) is a portable, fully shielded cabinet X-ray system that provides high resolution 2D and 3D radiographic images of surgically excised specimens. The VSI system consists of an image-acquisition device and software for image reconstruction, visualization, and archival. Enabled by optimized imaging geometry and iterative image reconstruction algorithm, VSI provides superior spatial and contrast resolution for visualizing specimens with soft tissues or boney structures. VSI is designed to comply with 21 CFR 1020.40 and DICOM standards.

Dear Dr. Han:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see
