No reference devices were used in this submission.
No
The summary does not mention AI, ML, deep learning, or any related terms. The functionality described is based on image processing and tracking systems, not AI/ML algorithms.
No
Explanation: While TrackX aids in diagnosis and treatment by improving the accuracy of surgical instrument placement, it does not directly treat disease or restore health. It is a tool that enhances the physician's ability to perform therapeutic procedures, but it is not a therapeutic device itself.
No
Explanation: TrackX is a software application that assists in the treatment of disease by aiding physicians in repositioning surgical instruments during procedures involving a fluoroscope. While it "captures diagnostic images," its primary function is to track instruments and provide visual feedback for treatment, not to make a diagnosis or provide diagnostic information.
No
The device description explicitly states that TrackX interfaces with an off-the-shelf tracking system (electromagnetic or optical) which requires physical components (trackers) to be mounted on the surgical instrument and the fluoroscope. While the core processing is software, it relies on and integrates with external hardware components for its primary function of tracking.
Based on the provided information, TrackX is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the examination of specimens derived from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, monitoring, or treatment of disease.
- TrackX's Function: TrackX is a software application that works with a fluoroscope to track the position of surgical instruments relative to the fluoroscope and manipulate X-ray images. It aids in surgical procedures by providing visual feedback on instrument position.
- No Specimen Examination: TrackX does not examine any specimens derived from the human body. Its function is entirely focused on image processing and instrument tracking during a medical procedure.
Therefore, TrackX falls under the category of medical devices used for image guidance and surgical assistance, not In Vitro Diagnostics.
N/A
Intended Use / Indications for Use
TrackX is intended for use in any application where a fluoroscope is incorporated to aid in diagnosis and treatment of disease.

Device Description
TrackX is a software application which captures diagnostic images using a fluoroscope via a video cable. In addition. TrackX interfaces with an off-the-shelf tracking system in order to track the position of surgical instruments relative to the fluoroscope. The user controls and views information via a primary monitor. The viewing monitor is not part of the subject device.
TrackX will track the location of the tip of a surgical instrument. Instrument tracking is accomplished using either an electromagnetic or optical tracking system with one tracker mounted on the surgical instrument and another tracker mounted on the fluoroscope. When used with an electromagnetic tracking system. Civco's eTRAX Needle Tip Tracking system is used. When used with an optical tracking system. TrackX snaps are used.
The tracking information is then fed into the TrackX software which manipulates the location of an X-ray image based on movement of the tracked surgical instrument tracking aids the physician in repositioning their surgical instruments by providing visual feedback on where they have moved their instruments between X-ray images. Additionally, TrackX can register the current image being taken (which contains the surgical instrument) with a prior Baseline image of the same anatomy and then use the Baseline image as a Background which the current image is translated over as part of instrument tracking.
TrackX can be used with either electromagnetic tracking or optical tracking. The C-arm tracking feature of the predicate device creates a viewfinder for the fluoroscope which allows the user to track the C-arm movement as they localize and relocalize the fluoroscope during an intervention. While TrackX does not provide this feature, it is still necessary to mount components to the Carm so that its position can be tracked. The C-arm's tracked position is used to detect the Carm's orientation and to track the position of instruments relative to the C-arm.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench Testing
- Instrument Tracking with Optical: Verified that TrackX with the Polaris optical tracking system can guide the user back to the location where the instrument was in the previous X-ray image so that the instrument is close enough to the original location to perform a medical intervention. The testing demonstrated that TrackX met specifications.
- Instrument Tracking with EM: Verified that TrackX with the Ascension electromagnetic tracking system can guide the user back to the location where the instrument was in the previous X-ray image so that the instrument is close enough to the original location to perform a medical intervention. The testing demonstrated that TrackX met specifications.
- Glyph Tracking Regression Test: Verified that the digital rotation and reflection of the fluoroscope image can be tracked with the glyph detection function in TrackX. The results demonstrated that the glyph detection meets the requirements for accuracy, precision, and speed required by TrackX, as specified in the Software Requirement Specification.
- Image Registration Performance Regression: Verified that when the TrackX software is installed on a computer, it can perform Image Registration within time and resolution constraints specified in the Software Requirement Specification. For all computer platforms tested, TrackX was able to display and register images well within the required speeds.
- Image Registration Regression: Verified that the changes introduced to the code in the transition from the previously cleared LessRay to TrackX do not adversely affect the ability of TrackX to register images. The results of the study demonstrated that the image registration algorithm performs the same in the subject as it does in the predicate device. Both algorithms correctly registered images that should be registered and rejected images that should not be registered. Studies on live pigs and parallax studies provided with the predicate LessRay submission demonstrate that TrackX is able to register a static baseline with an X-ray taken under conditions where the anatomy is moving or where the fluoroscope or patient have been moved. The studies demonstrate that TrackX is capable of working during interventions on living animals, with patient shift, and with organ/structure motion.

DEVICE DESCRIPTION 4.
TrackX is a software application which captures diagnostic images using a fluoroscope via a video cable. In addition. TrackX interfaces with an off-the-shelf tracking system in order to track the position of surgical instruments relative to the fluoroscope. The user controls and views information via a primary monitor. The viewing monitor is not part of the subject device.
TrackX will track the location of the tip of a surgical instrument. Instrument tracking is accomplished using either an electromagnetic or optical tracking system with one tracker mounted on the surgical instrument and another tracker mounted on the fluoroscope. When used with an electromagnetic tracking system. Civco's eTRAX Needle Tip Tracking system is used. When used with an optical tracking system. TrackX snaps are used.
The tracking information is then fed into the TrackX software which manipulates the location of an X-ray image based on movement of the tracked surgical instrument tracking aids the physician in repositioning their surgical instruments by providing visual feedback on where they have moved their instruments between X-ray images. Additionally, TrackX can register the current image being taken (which contains the surgical instrument) with a prior Baseline image of the same anatomy and then use the Baseline image as a Background which the current image is translated over as part of instrument tracking.
TrackX can be used with either electromagnetic tracking or optical tracking. The C-arm tracking feature of the predicate device creates a viewfinder for the fluoroscope which allows the user to track the C-arm movement as they localize and relocalize the fluoroscope during an intervention. While TrackX does not provide this feature, it is still necessary to mount components to the Carm so that its position can be tracked. The C-arm's tracked position is used to detect the Carm's orientation and to track the position of instruments relative to the C-arm.
TrackX is designed per recommendations provided in the following FDA guidance documents:

5. INDICATION FOR USE
The indications for use statement is identical to that of the predicate device:
TrackX is intended for use in any application where a fluoroscope is incorporated to aid in diagnosis and treatment of disease.
6. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
The markers TrackX snaps used with the TrackX software are identical to markers used with the predicate device.
The predicate device is the NuVasive LessRay with Enhanced Tracking as cleared in K170800.
As described in K170800, the NuVasive LessRay with Enhanced Tracking system provides three core features: image enhancement, c-arm tracking, and instrument tracking. TrackX, the subject device of this 510(k), only includes the instrument tracking feature, in which TrackX uses the tracked location of the tip of a surgical instrument to provide visual cues to the user in repositioning the instrument (image enhancement and c-arm tracking are not included in TrackX). TrackX uses the same codebase as the instrument tracking component of the NuVasive LessRay with Enhanced Tracking system cleared in K170800. Therefore, the information provided in the submission supports the substantial equivalence of the TrackX instrument tracking system to the instrument tracking functionality cleared in the NuVasive LessRay with Enhanced Tracking, K170800.

The differences between the subject device and the predicate device do not change the fundamental technology or the intended use of the device. Therefore, based on the identical
7
indication, similar technological characteristics, and results of performance testing, TrackX is substantially equivalent to the NuVasive LessRay with Enhanced Tracking as cleared in K170800.
7. PERFORMANCE DATA
The following performance data were provided in support of the substantial equivalence determination.
Biocompatibility
There are no direct or indirect patient-contacting components of the subject device. Therefore, biocompatibility testing is not needed for this device.
Sterilization and Shelf Life
Like the predicate device, the only sterile components are the TrackX Snaps that are attached to the instrument. The TrackX Snaps are identical to the NuX Snaps cleared in K170800. No changes have been made to the snaps, their packaging or the sterilization methods. Therefore, the information provided in K170800 is applicable to the subject device.
TrackX Snaps are provided sterile, for single use only, and labeled with a three-year shelf life. The snaps are sterilized using Gamma sterilization, and the sterilization method has been validated in accordance with AAMI/ISO 11137-1 Sterilization of health care products -Radiation - Part 1: Requirements for development, validation, and routine control of sterilization process for medical devices (2006) to demonstrate a Sterility Assurance Level (SAL) of 10 °.
Accelerated aging tests were conducted to support a three-year shelf life on samples having been packaged and sterilized to a single (validated) sterilization cycle. The validated cycle includes a minimum of 25 kGy and a maximum of 40 kGv exposure and is the same process used to sterilize the final device.
When used with an electromagnetic tracking system, Civco's eTRAX Needle Tip Tracking system is used. The eTRAX system is purchased off the shelf and is not provided as part of the TrackX System. No changes are made to the eTRAX Needle System for its use with TrackX and it is used in accordance with its off the shelf labeling. Sterilization and shelf life information can be obtained in the instructions for use provided with the eTRAX system.
Electrical Safety and Electromagnetic Compatibility (EMC)
The components of TrackX are software and hardware mounting components only. Use of TrackX includes a fluoroscope, a general-purpose computer and a compatible tracking system, which are all off-the-shelf components provided by the end user. The use of the TrackX software and hardware mounting components would have no impact on EMC or Electrical Safety. Therefore, EMC and Electrical Safety evaluation was not required by FDA for the predicate device, and is not applicable for the subject device.
Software Verification and Validation Testing
Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of
8
Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate" level of concern.
Bench Testing
Instrument Tracking with Optical
The purpose of this testing was to verify that TrackX with the Polaris optical tracking system is able to guide the user back to the location where the instrument was in the previous X-ray image so that the instrument is close enough to original location to perform a medical intervention. The testing demonstrated that TrackX met specifications.
Instrument Tracking with EM
The purpose of this testing was to verify that TrackX with the Ascension electromagnetic tracking system is able to guide the user back to the location where the instrument was in the previous X-ray image so that the instrument is close enough to original location to perform a medical intervention. The testing demonstrated that TrackX met specifications.
Glyph Tracking Regression Test
The purpose of this testing was to verify that the digital rotation and reflection of the fluoroscope image can be tracked with the glyph detection function in TrackX. The results demonstrated that the glyph detection meets the requirements for accuracy, precision, and speed required by TrackX, as specified in the Software Requirement Specification.
Image Registration Performance Regression
The purpose of this testing was to verify that when the TrackX software is installed on a computer. it can perform Image Registration within time and resolution constraints specified in the Software Requirement Specification. For all computer platforms tested, TrackX was able to display and register images well within the required speeds.
Image Registration Regression
TrackX uses the same codebase as the instrument tracking component of the NuVasive LessRay with Enhanced Tracking system cleared in K170800. The purpose of this regression testing was to verify that the changes introduced to the code in the transition from the previously cleared LessRay to TrackX do not adversely affect the ability of TrackX to register images. The results of the study demonstrated that the image registration algorithm performs the same in the subject as it does in the predicate device. Both algorithms correctly registered images that should be registered and rejected images that should not be registered. Studies on live pigs and parallax studies provided with the predicate LessRay submission demonstrate that TrackX is able to register a static baseline with an X-ray taken under conditions where the anatomy is moving or where the fluoroscope or patient have been moved. The studies demonstrate that TrackX is capable of working during interventions on living animals, with patient shift, and with organ/structure motion.
Clinical Study
Not applicable. Clinical studies are not necessary to establish the substantial equivalence of this device.

8. CONCLUSIONS
As described above, based on the Indication for Use identical to the predicate device, similar technological characteristics, and results of performance testing, TrackX is substantially equivalent to the NuVasive LessRay with Enhanced Tracking as cleared in K170800.
