Intended Use

MIM software is intended for trained medical professionals including, but not limited to, radiologists, oncologists, physicians, medical technologists, dosimetrists, and physicists. MIM software can be used by clinicians to assist in diagnosis, staging, treatment planning, monitoring treatment response, and treatment evaluation. MIM is a medical image and information management system that is intended to receive, transmit, store, retrieve, display, print and process digital medical images, as well as create, display, and print reports from those images. The medical modalities of these medical imaging systems include, but are not limited to, CT, MR, CR, DX, MG, US, SPECT, PET and XA as supported by ACR/NEMA DICOM 3.0. MIM provides the user with the means to display, register and fuse medical images from multiple modalities. Additionally, it evaluates cardiac left ventricular function and perfusion, including left ventricular end-diastolic volume, end-systolic volume, and ejection fraction. The Region of Interest (ROI) feature reduces the time necessary for the user to define objects in medical image volumes by providing an initial definition of object contours. The objects include, but are not limited to, tumors and normal tissues. MIM provides tools to quickly create, transform, and modify contours for applications including, but not limited to, quantitative analysis, aiding adaptive therapy, transferring contours to radiation therapy treatment planning systems and archiving contours for patient follow-up and management. MIM aids in the assessment of PET/SPECT brain scans. It provides automated quantitative and statistical analysis by automatically registering PET/SPECT brain scans to a standard template and comparing intensity values to a reference database or to other PET/SPECT scans on a voxel-by-voxel basis, within stereotactic surface projections or standardized regions of interest. MIM allows the dose distribution of an implant to be individually shaped for each patient and is a general purpose brachytherapy planning system used for prospective and confirmation dose calculations for patients undergoing a course of brachytherapy using permanent implants of various radioisotopes (not including radioactive microspheres). MIM allows voxel-based dose calculations for patients who have been administered radioisotopes or radioactive microspheres. MIM assists with the planning and evaluation of ablation procedures by allowing the energy zone that comprises the ablation zone to be visualized on medical imaging through the placement of virtual ablation devices for the purpose of confirming ablation zone placement.

# Device Description

The subject MIM – LesionID Pro device is a standalone software application that extends the functionality of the MIM software device. It is a modification to the predicate MIM software application (K243012) for incorporating updates to the LesionID Pro option that is commercially available in the currently distributed version of MIM software.

LesionID Pro assists users with the evaluation of PSMA PET/CT and SPECT/CT studies by automating hotspot segmentation and physiological uptake removal, to help reduce manual processing and streamline generation of Total Tumor Burden (TTB) statistics. It is provided via MIM Workflows that allow automation using scripts constructed of MIM software modular functions and commands.

LesionID Pro does not determine final hotspots segmentation for TTB generation, and requires users to review, edit, and confirm the segmentation before generating TTB statistics. The modifications made to LesionID Pro optimize the identification and removal of physiological uptake, automates the processing for a more streamlines workflow, and introduced enhancements related to user interface and experience.

The datasets included both PSMA PET/CT and SPECT/CT studies, spanning factors various relevant to the evaluation of LesionID Pro's segmentation performance (e.g. radiotracers, disease burden, imaging systems)

The clinical testing included qualitative clinical reader evaluation. The evaluation was performed by United States board certified NM physicians through scoring of clinically representative PSMA PET/CT and SPECT/CT patient clinical studies. The readers were requested to assess whether the initial segmentation generated by LesionID Pro was of acceptable quality for clinical use in the context of PSMA PET and SPECT TTB segmentation and evaluation.

The testing and results did not raise new or different questions of safety and effectiveness than associated with predicate devices.

## Conclusion

The subject device MIM – LesionID Pro has been developed according to MIM Software Inc.'s established design control process and software development life cycle.
