2. Sample Size Used for the Test Set and Data Provenance
- 170 CT Guided Interventions:
- Sample Size: 170 needle placements
- Provenance: Outside of the USA (retrospective analysis of interventions performed by users of MAXIO™)
- 20-Patient Liver Ablation Study:
- Sample Size: 20 patients, 40 tumors
- Provenance: University of Malaya Medical Center, Kuala Lumpur (likely prospective)
- CRO-supervised study on skin marker/laser alignment:
- Sample Size: 14 patients
- Provenance: Global Hospitals, Chennai, India (likely prospective)
- Animal Study (needle placement accuracy):
- Sample Size: 6 animal liver targets, 35 needle placements
- Provenance: Memorial Sloan Kettering Cancer Center (likely prospective)
- Bench Tests: Used static phantom, not human or animal data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
The document does not explicitly state the number of experts used to establish ground truth or their specific qualifications for any of the studies mentioned. It generally refers to "qualified users" or "physicians trained for CT procedures." For the animal study, it mentions comparison to "freehand placement by experts," implying expert involvement but not quantifying or qualifying them.
4. Adjudication Method for the Test Set
The document does not specify any formal adjudication method (e.g., 2+1, 3+1) for establishing ground truth in any of the studies.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- Was it done? The document mentions an animal study where "the accuracy of needle placement with MAXIO assistance is comparable to freehand placement by experts however fewer needle manipulations, check-scans." This implies a comparison between human performance (experts doing freehand) and human performance with AI assistance (MAXIO™ assistance).
- Effect size of how much human readers improve with AI vs. without AI assistance: The document states "fewer needle manipulations, check-scans" with MAXIO™ assistance compared to expert freehand. It doesn't provide a quantitative "effect size" or specific percentage of improvement, but rather a qualitative benefit in procedural efficiency.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
The accuracy targets, segmentation accuracy, and registration accuracy were demonstrated through "bench tests" using a "static phantom." This portion of the evaluation appears to be a standalone assessment of the device's capabilities without human intervention, focusing on its technical precision.
7. Type of Ground Truth Used
- Bench Tests (Accuracy, Segmentation, Registration): Likely based on precisely known measurements from a static phantom and potentially expert-defined benchmarks or measurements for segmentation/registration.
- Clinical/Animal Studies:
- Needle Placement Accuracy: Most likely determined by subsequent imaging (e.g., CT scans) to verify the actual needle tip position relative to the planned target, along with clinical outcomes or observations during the procedure. The "accurate needle placement using MAXIO for CT guided Tumor ablations" in the 20-patient study points to this.
- Patient Movement Detection/Correlation: Verified through direct observation, measuring shifts, and comparing skin marker data to anatomical movement in CT scans.
- Needle Manipulations/Check-scans: Direct observation and recording during the procedures.
8. Sample Size for the Training Set
The document does not provide any information about a training set or its sample size. The studies described are primarily for validation of the device's performance.
9. How the Ground Truth for the Training Set Was Established
Since no training set is described, there's no information on how its ground truth was established.

Discussion of differences:
Mounting the device to the floor mat using InstaReg in MAXIO™ achieves the same purpose of bringing the arm repeatedly to the same point as permanently fixing the arm to the CT Gantry in predicate PinPoint (K9745). Floor mounting and Ceiling mounting are commonly employed docking techniques in the industry and this dissimilarity does not raise additional safety and effectiveness issues.
Using motors to move the axes of an electromechanical arm, as done in MAXIO™, is a well established practice in the motion control industry. Alternatively the axes can be moved manually as in the predicate PinPoint (K974513).
MAXIO™ uses a well established collision avoidance algorithm to prevent arm - instrument and instrument - instrument interference, in addition to the physician assessing any possible interference prior to placement and arm pullback.
For procedure planning, MAXIO™ provides the physician the ability to plan needle placement on current CT images and on registered images from multiple series. Predicates ig4 (K060903) and Pinpoint (K974513) to allow planning only on current CT images. The registration feature offered by MAXIO™ is a well understood and commonly deployed technique in image guided procedures. In addition MAXIO™ registration accuracy has been bench tested and found acceptable.
For verification, MAXIO™ and its predicates ig4 (K060903) and Pinpoint (K974513) provide physicians the ability to visualize instrument(s) or targets using current CT images. In addition MAXIO™ provides intra-operative CT image registration with plan images to verify instrument position, whereas ig4 (K060903) uses electromagnetically tracked instruments to verify instrument position. MAXIO™ provides similar registration of post-procedure CT images to

compare the treated organ with plan. The registration feature offered by MAXIO™ is a well understood and commonly deployed technique in image guided procedures. In addition MAXIO™'s registration accuracy has been bench tested and found acceptable.
In addition all disposables that may come in contact with the patient or the user, directly or indirectly, have been tested in accordance to the US standards prior to commercial marketing of the device.
In addition, MAXIO™ has been bench tested to demonstrate that it meets the performance requirements for its intended use. Additionally, the following data demonstrates that MAXIO™'s stereotactic navigation is accurate and repeatable across various clinically relevant conditions:
- An analysis of 170 needle placements performed using MAXIO™ outside of the USA. .
- A 20 patient study using MAXIO™ for liver ablation. .
- A 35 needle placement study using MAXIO™ on 6 animal liver targets. .
Therefore it has been concluded that the MAXIO™ is substantially equivalent to its predicates ig4 Image Guided System (K060903) and PinPoint (K974513) for its intended use.
