The Adaptix Ortho350 is intended to be used in hospitals, clinics, imaging centers, and/or other healthcare facilities by qualified/ trained doctors or technicians on both adult and pediatric subjects.
The Device is intended to generate tomosynthesis images of human anatomy for diagnostic purposes of body extremities, upper/lower limbs, and adjacent anatomy in all routine radiography examinations.
The device is not intended/indicated for use in imaging of the skull, chest, spinal column, hip, shoulder or in mammography applications.
The Adaptix Ortho350 (K252133) is a 3D tomographic X-ray device intended to generate tomosynthesis images of human anatomy for diagnostic purposes of body extremities, upper/lower limbs, and adjacent anatomy in all routine radiography examinations. The device comprises of an Ortho350 C-Arm Assembly and a Control PC. It is also possible to create 2D X-ray images of the desired anatomy.
The Adaptix Ortho350 device is a portable system that can be placed on a benchtop or the floor or mounted on an optional cart for added mobility. To obtain 3D tomosynthesis images, the relevant area of the patient is positioned against the detector cover then X-rays are emitted from a controlled sequence of locations. The system uses a low-power, monoblock X-ray source with integrated controls and feedback, synchronized electronically with the detector for tomosynthesis image acquisition. The system is operated by an X-ray technologist or suitably qualified healthcare professional using and designed with safety features to only allow X-ray emission when multiple controls are in place.

Dear Prithul Bom:
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 (the 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 available 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.

Overall, the software for the Ortho350 system was determined as a Safety Class 'B' under IEC 62304. All design requirements and risk mitigations passed their planned verification and validation tests.
Cybersecurity Testing
Security Requirements Testing, Threat Mitigation Testing, Vulnerability Testing, and Penetration Testing were performed on the Adaptix Ortho350 System in line with IEC 81001-5-1 (2022) and the FDA's Guidance for Industry and FDA Staff - Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions (2023). The testing concluded that the Ortho350 system is safe to install and operate within a HDO environment from a cybersecurity perspective.
Transport Testing
Transport verification was performed on the Ortho350 device within its packaging to ensure that the device could be reliably delivered to end users without sustaining damage that could affect its performance, safety, or usability. The verification was done in accordance with ASTM D4169-22, which included environmental conditioning, mechanical handling (e.g., incline impacts and drops), and vibration testing. The overall testing concluded that the Ortho350 system, along with its chosen packaging solution, can safely endure the rigors of transportation. The overall outcome of the study was a conclusive pass, validating that the product is fit for shipment and capable of immediate operation upon delivery.
Image Verification Testing
Image Quality verification testing was conducted using geometrical phantoms, adult human cadavers and an anthropomorphic pediatric phantom. Digital tomosynthesis images and standard 2D radiographs evaluated by qualified independent radiologists and orthopedic clinicians from the USA and UK. The tests included assessments of the impact of typical image and motion artifacts, including an assessment of image artifacts in the presence of metal. The tests confirmed that images were clinically acceptable and within the intended use for diagnosis for both adult and pediatric patients.
Hardware Verification Testing
Verification of the main hardware components of the Ortho350 device (Source and Stage Control Board and C-Arm Desktop Assembly) were performed against their corresponding requirements. The overall verification activities passed accordingly.
