These changes differ when comparing to Contour ProtégéAl 510(K)213976. Noninferiority testing was used to compare the proposed Contour ProtégéAl device to Atlases created from the MIM Maestro (K071964) reference device. ## Testing and Performance Data For the proposed Contour ProtégéAl device, the new 4.0.0 CT neural network models were trained on a pool of training data that did not include any patients from the same institution as the test subjects. This training data included 326 CT images gathered from 37 clinical sites across multiple countries. Models were trained using images of adults at various ages. No ethnicities or genders were excluded from training. The models were then evaluated on the test subjects from a pool of 819 independent images gathered from 10 institutions. The CT images for this training set were obtained from clinical treatment plans for patients prescribed external beam or molecular radiotherapy, but the original segmentations were not used. Instead, the images were re-segmented by consultants (physicians and dosimetrists) specifically for this purpose, outside of clinical practice. Detailed instructions derived from relevant published clinical contouring guidelines were prepared for the dosimetrists. The initial seqmentations were then reviewed and corrected by a radiation oncologist against the same standards and quidelines. Qualified staff at MIM Software (M.D. or licensed dosimetrists) then performed a final review and correction. All segmenters and reviewers were instructed to spend {12}------------------------------------------------ Image /page/12/Picture/0 description: The image shows the logo for MIM Software.

In particular, the consultants were asked to contour all specified OAR structures on all images to according to referenced standards. whether or not they were proximal to the treatment field. All patients were imaged on an indexed couch in treatment position ("simulation CT"). Series that were non-axial, had slices thinner than 0.5mm, or had non-Fan Beam or mV acquisitions were excluded. The verification data used for testing is from a set of institutions that are totally disjoint from the training datasets used to train each model in the Contour ProtégéAl device. The predicate MIM device was confiqured with Atlases built from the same training data used to train the models. We tested Contour ProtégéAl against the predicate device, and the goal of this testing is to show that it is equivalent or superior to the predicate. The performance of both segmentation devices was measured by calculating the Dice score of the novel segmentations with the original ground-truth contours. Any structure that ends up being statistically significantly worse than MIM atlas segmentation predicate device will be removed from the final model. The mean and standard deviation Dice coefficients, along with the lower 95th percentile confidence bound, were calculated for both the proposed Contour ProtégéAl device and the MIM Maestro atlas segmentation reference device for each structure of each neural network model. Contour ProtégéAl results were equivalent or had better performance than the MIM Maestro atlas segmentation reference device. Equivalence is defined such that the lower 95th percentile confidence bound of the Contour ProtégéAl segmentation is greater than 0.1 Dice lower than the mean MIM atlas segmentation reference device performance. | 4.0.0 CT Model: | Structure: | MIM Atlas | Contour ProtégéAI | |-----------------|-----------------|-------------|------------------------| | Head and Neck | Bone_Mandible | 0.81 ± 0.07 | 0.85 ± 0.07 (0.82) * | | Head and Neck | BrachialPlex_L | 0.17 ± 0.08 | 0.26 ± 0.10 (0.19) * | | Head and Neck | BrachialPlex_R | 0.15 ± 0.07 | 0.25 ± 0.11 (0.16) * | | Head and Neck | Brain | 0.97 ± 0.01 | 0.98 ± 0.01 (0.97) * | | Head and Neck | Brainstem | 0.78 ± 0.09 | 0.82 ± 0.09 (0.78) * | | Head and Neck | Cavity_Oral | 0.75 ± 0.14 | 0.77 ± 0.12 (0.69) * | | Head and Neck | Cochlea_L | 0.19 ± 0.15 | 0.27 ± 0.17 (0.20) * | | Head and Neck | Cochlea_R | 0.17 ± 0.15 | 0.29 ± 0.18 (0.21) * | | Head and Neck | Eye_L | 0.80 ± 0.08 | 0.87 ± 0.06 (0.84) * | | Head and Neck | Eye_R | 0.80 ± 0.10 | 0.87 ± 0.06 (0.83) * | | Head and Neck | Glnd_Lacrimal_L | 0.22 ± 0.17 | 0.39 ± 0.17 (0.27) * | | Head and Neck | Glnd_Lacrimal_R | 0.23 ± 0.16 | 0.43 ± 0.15 (0.32) * | | Head and Neck | Glnd_Submand_L | 0.57 ± 0.13 | 0.77 ± 0.10 (0.69) * | | Head and Neck | Glnd_Submand_R | 0.56 ± 0.16 | 0.77 ± 0.09 (0.68) * | | 4.0.0 CT Model: | Structure: | MIM Atlas | Contour ProtégéAI | | | Glnd_Thyroid | 0.47 ± 0.18 | 0.71 ± 0.16 (0.59) * | | | Lens_L | 0.22 ± 0.23 | 0.61 ± 0.17 (0.52) * | | | Lens_R | 0.22 ± 0.22 | 0.63 ± 0.15 (0.54) * | | | Lips | 0.38 ± 0.14 | 0.38 ± 0.14 (0.28) * | | | OpticChiasm | 0.04 ± 0.07 | 0.12 ± 0.11 (0.08) * | | | OpticNrv_L | 0.45 ± 0.15 | 0.53 ± 0.13 (0.46) * | | | OpticNrv_R | 0.44 ± 0.14 | 0.52 ± 0.12 (0.45) * | | | Parotid_L | 0.71 ± 0.10 | 0.80 ± 0.10 (0.75) * | | | Parotid_R | 0.71 ± 0.09 | 0.80 ± 0.06 (0.77) * | | | Pituitary | 0.38 ± 0.18 | 0.49 ± 0.15 (0.37) * | | | SpinalCord | 0.66 ± 0.14 | 0.63 ± 0.16 (0.57) * | | Thorax | BrachialPlex_L | 0.28 ± 0.14 | 0.37 ± 0.13 (0.25) * | | | BrachialPlex_R | 0.28 ± 0.11 | 0.36 ± 0.16 (0.23) * | | | Breast_L | 0.75 ± 0.10 | 0.74 ± 0.17 (0.65) * | | | Breast_R | 0.76 ± 0.11 | 0.77 ± 0.10 (0.71) * | | | Bronchus | 0.60 ± 0.17 | 0.66 ± 0.13 (0.56) * | | | Carina | 0.39 ± 0.18 | 0.51 ± 0.13 (0.43) * | | | Cricoid | 0.03 ± 0.05 | 0.03 ± 0.04 (-0.01) * | | | Esophagus | 0.49 ± 0.16 | 0.70 ± 0.15 (0.65) * | | | Glnd_Thyroid | 0.46 ± 0.18 | 0.67 ± 0.16 (0.57) * | | | GreatVes | 0.70 ± 0.08 | 0.74 ± 0.10 (0.65) * | | | Heart | 0.88 ± 0.08 |…
