Intended Use

OptimMRI is a software application intended to aid qualified medical professionals in processing, visualizing, and interpreting anatomical structures from medical images. The software can be used to process pre-operative DICOM compatible MR images to generate 3D annotated models of the brain that aid the user in neurosurgical functional planning. The annotated MR images can further be used in conjunction with other clinical methods as an aid in localization of the Subthalamic Nuclei (STN) and Ventral Intermediate Nucleus (VIM) regions of interest.

Device Story

OptimMRI is a software application for neurosurgical functional planning. It takes pre-operative DICOM MR images as input. Using semi-automatic machine learning models, it processes these images to generate 3D annotated markers for STN and VIM brain regions. The software is used by qualified medical professionals in a clinical setting. Output consists of 3D annotated models and images, which are reviewed and interpreted by the clinician to assist in surgical planning and localization of target regions. The device aids in clinical decision-making by providing visual anatomical guidance for neurosurgical procedures.

Clinical Evidence

Performance evaluation based on retrospective analysis of 44 cerebral MRIs (88 hemispheres) for STN and 31 cerebral MRIs (62 hemispheres) for VIM. Accuracy compared against reference devices Guide XT (K213930) and SureTune4 (DEN210003). Results showed ≥90% of surface distances for STN and VIM were ≤ 2.0mm. STN performance was identical to the predicate SIS Software.

Technological Characteristics

Software-based medical image processing system. Utilizes machine learning models for semi-automatic anatomical annotation. Compatible with DICOM standard. Complies with ISO 14971, IEC 62304, IEC 82304-1, ISO 15223-1, IEC 62366-1, ANSI UL 2900-1, and IEC 80001-1 standards. Cybersecurity controls implemented per AAMI TIR57.

Indications for Use

Indicated for qualified medical professionals to aid in neurosurgical functional planning by processing pre-operative DICOM MR images to localize Subthalamic Nuclei (STN) and Ventral Intermediate Nucleus (VIM) regions of interest.

Indications for Use:

OptimMRI is a software application intended to aid qualified medical professionals in processing, visualizing, and interpreting anatomical structures from medical images. The software can be used to process pre-operative DICOM compatible MR images to generate 3D annotated models of the brain that aid the user in neurosurgical functional planning.

### Comparison to Predicate Device

The OptimMRI software is substantially equivalent to the predicate that has already been cleared for USA distribution with 510(k) premarket notification number K162830. Briefly, the subject and predicate devices are based on the following same technological elements:

- . Software tools for the visualization of DICOM compliant medical images
- . Permit specialized annotation of anatomic structures using machine learning models
- . Output data compatible with multiple surgical planning systems
- Support for 2D and 3D visualization tools ●
- Export of images and reports in DICOM format ●

The following technological differences exist between the subject and predicate device:

- . Subject device is indicated for only pre-operative usaqe
- Segmentation process is semi-automatic for subject . device compared to fully automatic for the predicate device
- . Fusion imaging capability is not available in the subject device

- Region of interest is annotated with 3D crosses on the ● subject device compared to 3D segmented anatomical volumes on the predicate
- Localization of VIM region of interest is not available on . the predicate device

Accuracy of segmentations for OptimMRI was compared to previously cleared commercially available comparable software tools. A total of 44 cerebral MRIs (88 hemispheres) were retrospectively annotated for the STN performance study, and 31 cerebral MRIs (62 hemispheres) were used for the VIM study. Qualified and experienced medical professionals performed the segmentation, and all validation criteria were met. The performance evaluation studies against reference devices Guide XT (K213930) and SureTune4 (DEN210003) demonstrated that at least 90% of surface distances of STN or VIM were not greater than 2.0mm when using segmentation tools for OptimMRI. The STN result is identical to the predicate SIS Software that used highresolution 7T MRIs of the brain.

No new safety or efficacy issues were introduced by OptimMRI compared to the predicate device. There are no differences in indications for use between OptimMRI and the Software (K162830). predicate ટાટ Furthermore, performance data demonstrate that the functionality, output and clinical usage of OptimMRI is substantially equivalent to the predicate device.
