Intended Use

Vitrea® Image Denoising software is intended to assist radiologists and specialists in the enhancement of CT and 3D-XA image presentation by enabling noise reduction and contrast enhancement technique.

Device Story

Software tool for radiology workstations; processes CT and 3D-XA images. Performs 3D analysis of voxel neighborhoods to distinguish random noise from dominant structural features; suppresses noise by averaging voxel data while preserving structural details. User-controlled via presets in MPR and 3D views; allows interactive application/removal of filters and creation of custom presets. Output is denoised image series for visual assessment.

It assists radiologists and specialists in the enhancement and viewing of CT and 3D-XA images from a variety of diagnosis imaging systems by noise reduction and contrast enhancement. Vitrea Image Denoising software employs 3D analysis of the image structure of each voxel. Random noise does not have a 3D structure and can thus be separated from dominant structures. Once the structure has been determined, the denoising tool suppresses noise by averaging voxel information without removing important structural details for reducing the noise. It provides a control to turn on or off a denoising preset in Multi-planar Reformatting (MPR) and 3D views to reduce noise and enhance contrast in reconstructed CT and 3D-XA image datasets, while preserving structural details of contrast, spatial size, and 3D structure in the native images for visual assessment. The user can interactively apply and remove the noise reduction filter during the image review to assess the effect of the noise reduction on the images and generate a new series of denoised snapshots for further review in other workstations or PACS. The denoised images can be used in conjunction with the original images as the user can switch between the original image and the denoised image while conducting image review. It also enables the user to create new denoising presets, edit existing denoising presets, and save the current denoising values as a custom preset. {1}------------------------------------------------ # Vitrea® Image Denoising Software 510(k) Pre-market Notification A Toshiba Medical Systems Group Company # Intended Use / Indications for Use: Vitrea® Image Denoising software is intended to assist radiologists and specialists in the enhancement of CT and 3D-XA image presentation by enabling noise reduction and contrast enhancement technique. # Intended for Disease / Condition / Patient Population: Not applicable as this is a medical image post processing software tool for image enhancement. # Substantial Equivalence: With regards to safety, the Vitrea Image Denoising software is substantially equivalent to the currently marketed post-processing noise reduction software products that analyze data from medical images.

Statistical analysis distinguishes between the two by studying the statistical distribution of the data whereas 3D analysis studies the first and second order derivatives of the image data to determine the dominant direction of structure if it exists. | Vital Images believes that Vitrea Image Denoising software has the same intended use i.e. enhancement of CT and 3D-XA images, similar indication statement i.e. to be used by trained radiologists and specialists at a medical facility, and similar technological characteristics i.e. image-space noise reduction method as the predicate device. The above noted difference in the method of image structure analysis, i.e. Vitrea Image Denoising software uses 3D analysis and Sapheneia Clarity uses statistical analysis method to analyze image structure; does not alter the end result of the software, which is to distinguish structure from noise. Vital Images believes that the verification and validation results demonstrate that Vitrea Image Denoising software is as safe and effective as the predicate device and raises no new issues of safety and effectiveness as compared to the predicate devices. Therefore, Vital Images believes that FDA should find Vitrea Image Denoising software to be substantially equivalent to the predicate device, Sapheneia Clarity. # Summary of Non-Clinical Tests: The software was designed, developed and tested according to written procedures that included applying risk management. Software testing was completed to ensure the new feature operates according to its requirements and without impact to existing functionality. Testing included verification, validation, and evaluation of previously acquired medical images. The following quality assurance measures were applied to the development of Vitrea Image Denoising software: - Risk analysis . - Requirements reviews . - Design reviews . - Verification of the software that included performance and safety testing . - Validation of the software that included phantom testing and simulated usability testing by . independent experienced medical professionals. {5}------------------------------------------------ ### Risk analvsis: Vital Images performed a risk analysis, referring to software hazards associated with the intended use, including severity assessment and mitigation. The analysis was based upon the application of ISO 14971:2012 risk management to medical devices, in compliance with medical device ISO 13485:2012 and IEC 62304:2006 requirements. All identified risks were reduced as low as possible. The medical benefits of the software outweigh the residual risk for each individual risks together. The overall residual risk for the software was deemed acceptable. #### Verification: The software verification team's primary goal is assuring the software fully satisfies all expected system requirements and features. Test cases were executed against the system features and requirements. As part of creating the test cases, the verification team reviewed and monitored the Requirements Traceability Matrix ("RTM") to ensure coverage of the items within the RTM. #### Validation: The software validation team's primary goal is assuring the software conforms to user needs and intended use. The validation team conducted workflow testing that provided evidence that the system requirements and features were implemented, reviewed and met. #### Internal Validation (Phantom Testing): The software validation team provided internal validation of Vitrea Image Denoising software. Internal validation included internal beta testing and internal user acceptance testing using various Catphan phantoms. The performed phantom tests validated that the amount of noise reduction is clinically significant considering the clinical use of the filter and the resulting spatial resolution, the level of image sharpness or spatial resolution after noise reduction remains acceptable for the diagnostic purposes and the low contrast resolution is not degraded after the noise reduction. #### External Validation: During external validation of Vitrea Image Denoising software, experienced Radiologists and an Interventional Cardiologist evaluated the Vitrea Image Denoising software. Each user felt that the Vitrea Image Denoising software reduces noise and enhances contrast in reconstructed CT and 3D-XA image datasets, while preserving structural details of contrast, spatial size, and 3D structure in the native images for clinically relevant visual assessment. #### Summary of Clinical Tests: The subject of this traditional 510(k) notification.
