A web-based interface provides users the needed functionality to display patient images and studies in commercially available web browsers. Patient images/studies can be accessed by users locally within the system or across a wide-area network at distributed locations. Acquisition can be included via integration with a DICOM-compatible imaging application or server configured to forward images to the XV Web database. The system allows users to: manipulate (e.g. rotate, flip, etc.): enhance (e.g. increase or decrease brightness/contrast, gamma correction); add labels (e.g. measurements, lines, arrows, etc.), annotations to patient images/studies and other relevant operations for diagnostic purposes.

Results produced by the software's diagnostic and treatment planning tools are dependent on the interpretation of trained and licensed practitioners. Dolphin Blue Imaging 2.0 is a software that provides imaging, diagnostics, and case presentation capabilities for dental specialty professionals. The Dolphin Blue Imaging 2.0 suite of software products is a collection of modules that together provide a comprehensive toolset for the dental specialty practitioner. Users can easily manage 2D images and x-rays; accurately diagnose and treatment plan, quickly communicate and present cases to patients and can work efficiently with colleagues on multidisciplinary cases. The below functionalities make up the medical device modules: # Tracing Module If a patient record contains a suitable image, cephalometric digitizing can be utilized to establish the locations of specific anatomical features. The inter-relational positions of these landmarks are used to render tracing lines and calculate cephalometric measurements, which are used in diagnosing patients and planning orthodontic and/or surgical procedures. An extensive library of existing cephalometric analyses is included with the software. The Blue Imaging server is used to manipulate the cephalometric landmark data. Storage in the patient's data record is done by utilizing Dolphin Data Storage. #### Measurements Module For images containing cephalometric tracing data, the user can view a list of measurements calculated according to the specific cephalometric analysis selected to view. Since digitized images contain only the locations of specific points (landmarks) on the patient anatomy, measurements lists are calculated in real-time by the Dolphin Blue Ceph server. Calculations take into consideration the race, gender, age, and customizable normal measurement values for a patient to indicate deviations from the accepted normal measurements. {6}------------------------------------------------ Image /page/6/Picture/0 description: The image shows a logo with two curved shapes facing each other. The shapes are blue and appear to be symmetrical. The logo is simple and modern, with a focus on the curved shapes. # Superimpositions Module If a patient record contains multiple x-ray images for which cephalometric data has been digitized, the resulting tracings can be overlaid to indicate changes and/or differences in the anatomy. These overlays (superimpositions) are displayed and manipulated within the Dolphin Blue Ceph user interface. The Dolphin Blue Ceph server is responsible for calculating and rendering superimpositions in real-time. The computer hardware used to access the web application must meet the following requirements: - . Operating System: Windows 10 or newer, Mac OS X (10.1 Yosemite) or newer - Intel Core i5 Processor . - 8 GB RAM . - 500 GB Hard Drive . - Gigabit Ethernet Adapter . - Screen Resolution 1366x768 . - Intel USB Chipset with USB 2.0 Ports (the number of ports needed will be based on what hardware will be used . on the workstation) - .

The shapes are mirror images of each other and are positioned so that they appear to be facing each other. The logo is simple and modern in design. The blue color is bright and eye-catching. #### Indications For Use: Dolphin Blue Imaging 2.0 software is designed for use by specialized dental practices for capturing, storing and presenting patient images and assisting in treatment planning and case diagnosis. Results produced by the software's diagnostic and treatment planning tools are dependent on the interpretation of trained and licensed practitioners. #### Performance Data/Safety and Effectiveness: Software Documentation for a Moderate Level of Concern software Document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" issued on May 11, 2005, is included as part of this submission. Verification and Validation activities have been successfully performed on the software package, including assurance that functions work as designed, performance requirements and specifications have been met, and that all hazard mitigations have been fully implemented. All testing has met the predetermined acceptance values. Traceability of the requirements specified in the requirement specifications and functions is ensured during component integration, software validation and system testing. Risk Management has been ensured via risk analyses in compliance with ISO 14971 to identify and provide mitigation to potential hazards beginning early in the design cycle and continuing throughout the development of the product. Patterson Companies adheres to recognized and established industry standards for development including EN ISO 13485 and IEC 62304. The device labeling contains instructions for use and any necessary cautions and warnings to provide for safe and effective use of the device.

The logo is likely used by a company or organization that wants to convey a message of innovation, collaboration, or balance. The logo is visually appealing and easy to remember. All Specifications of Dolphin Blue Imaging 2.0 are verified by several tests before release. Non-clinical testing, including verification tests, evaluated: - . Unit testing - . Performance Testing - Manual Testing ● - . Integration Testing - System and Regression testing ● #### Unit Testing Engineers perform unit testing before checking in code changes, to validate for the intended functionality. Code changes are validated for compilation upon check-in via an automated build process. #### Performance Testing Performance testing verifies the system stability and response under a specified workload and is conducted for each release. Data sets are utilized while testing several categories and evaluating if the page counts verify the system stability. #### Manual Testing Manual testing verifies the functions and features of the Dolphin Blue Imaging 2.0 product as an end-user would use the application to verify the software is working as designed and required. Manual tests are pre-defined #### Integration Testing Integration testing verifies the interconnections between applications and systems function correctly and evaluates whether systems or components pass data and control correctly to one another. #### System and Regression Testing System and regression testing are executed as part of the final testing on a release of a product. The plan includes the following as applicable: - a) System Tests executed as regression tests - b) Integration Tests executed as regression tests - c) other tests, such as exploratory testing executed as regression tests #### Substantial Equivalence Conclusion: Dolphin Blue Imaging 2.0 software was designed, tested, and validated according to written procedures. These procedures specify individuals within the organization responsible for developing product specifications, coding, testing, validating, and maintenance. Dolphin Blue Imaging 2.0 has successfully completed integration testing/verification testing and beta validation. In addition, potential hazards have been evaluated and controlled to an acceptable level. Dolphin Blue Imaging 2.0 has similar function of Cephalometric tracing and tracing/image superimposition like its predicate device. Dolphin Imaging is a desktop-based software and Dolphin Blue Imaging 2.0 a web-based software, the difference does not raise any new questions regarding safety or effectiveness of the device. Dolphin Blue Imaging 2.0 features were modeled after Dolphin Imaging features. Thus, Dolphin Blue Imaging 2.0 is substantially equivalent to the predicate devices.
