aprevo® Digital Workflow software is intended to view, store, and manipulate 3-D models to visualize surgical plans for spinal alignment. The device inputs a 3-D spine model which is used by trained, medically knowledgeable design personnel in conjunction with inputs from healthcare professionals to produce 3-D models of spinal correction and anatomical measurements. The device outputs are used by healthcare professionals for placement of surgical implants.
The aprevo® Digital Workflow is a proprietary software tool that visualizes and provides measurements of a healthcare professional's surgical plan for a spinal alignment. The software is used to input the patient's spine model, then view, store and measure the 3D spine model to create a visual representation of the desired surgical plan. The software is used to export the visualization of the surgical plan along with associated measurements. The Subject Device is operated by trained, medically knowledgeable Carlsmed design personnel while the output is reviewed and approved by a healthcare professional.
The provided text is a 510(k) summary for the aprevo® Digital Workflow device. It describes the device's indications for use, technological characteristics, and a brief section on performance data. However, it does not contain the detailed information required to answer the specific questions about acceptance criteria and the study proving the device meets those criteria.
The "PERFORMANCE DATA" section is very general, stating:
"The Subject Device has been evaluated in accordance with internal software specifications and applicable performance standards through the software development and verification and validation procedures to ensure performance according to specifications, user requirements, and the FDA guidance document Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices and Technical Performance Assessment of Quantitative Imaging in Radiological Device Premarket Submissions."
It also mentions:
"In addition, the measuring function of the Subject Device was evaluated in bench testing using in-silico phantoms with known values."
This information is insufficient to complete the requested table and answer the detailed questions about the study design, sample sizes, expert involvement, and ground truth establishment. The document explicitly states that the software is used by "trained, medically knowledgeable Carlsmed design personnel" and the output is "reviewed and approved by a healthcare professional," implying a human-in-the-loop workflow, but it doesn't provide a comparative effectiveness study.
Therefore, I cannot provide the detailed information requested in the format of the questions because it is not present in the provided text. The document focuses on demonstrating substantial equivalence to a predicate device based on intended use and technological characteristics, rather than a detailed performance study with specific acceptance criteria and results.

Dear Karen Liu:
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
{1}------------------------------------------------
devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

TECHNOLOGICAL CHARACTERISTICS
The aprevo® Digital Workflow will replace 510(k) cleared software in the implant design workflow to perform 3D model based surgical planning. The software functionality is equivalent to the predicate device (3Matics, K060950) based on the intended use and technological characteristics, and does not raise any new question of safety and effectiveness.
PERFORMANCE DATA
The Subject Device has been evaluated in accordance with internal software specifications and applicable performance standards through the software development and verification and validation procedures to ensure performance according to specifications, user requirements, and the FDA guidance document Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices and Technical Performance Assessment of Quantitative Imaging in Radiological Device Premarket Submissions.
In addition, the measuring function of the Subject Device was evaluated in bench testing using in-silico phantoms with known values.
CONCLUSION
The overall indications for use and technology characteristics of the aprevo® Digital workflow are similar to the primary predicate device. This leads to the conclusion that the proposed aprevo® Digital workflow is substantially equivalent to its primary predicate from the safety and effectiveness perspective.

(a)
Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.(b)
