The ExpertGuidance App gives you a fast, easy, and helpful first impression of your Siemens Healthineers equipment and its look & feel. This addition to the onboarding training at your facility allows you to familiarize yourself with the device and its functionalities β mobile and in real time. Hereβs what our ExpertGuidance App offers you: β Equipment introduction At this level, youβll receive basic information about the system, for example the ARTIS icono, and the possibilities it brings to everyday clinical practice. This initial introduction is guided by interactive hot-spots that, when clicked upon, provide you with detailed explanation. β Device simulation The simulation allows you to interact virtually with the device in a realistic way. The control panels in the app provide a wide range of the real functions. You can simulate realistic movements using the controls and familiarize yourself in some detail with them. β Augmented reality functionality: Using augmented reality (AR), you can place the device in a real physical space β scaled down to sit on a table or in its actual size to see it how it fits in your facility. AR also allows you to experience the movements realistically. This helps you understand the dynamics and scale of the system even better. Explore medical workflows and enhance your competency in complex clinical procedures to boost workforce confidence prior to performing a real patient case. Increase workforce satisfaction through fast and easily accessible education, while interacting with the equipment anytime, anywhere, on a mobile device. Currently, the ExpertGuidance App has been developed for iPad Pro (second generation or higher). Please be advised that you can only use the app on these compatible devices; otherwise, you may experience a reduction in performance. With the app, youβll only see the content you really need.

The objects in this application are the patient, X-ray machine and a color map depicting the radiation scattering. The purpose of this application is to demonstrate how the radiation generated during the X-ray imaging scatters to the environment.
