The BoneBox™ Spine Viewer is a real-time 3D medical education and patient communication tool, featuring a detailed anatomical spine model. It is a member of a series of apps developed specifically for the iPad 2 and the New iPad by a team of anatomists, certified medical illustrators, animators, and programmers using actual human CT imaging data, and the most accurate 3D modeling technology available. The BoneBox™ Spine Viewer is appropriate for use by secondary students, undergraduate and graduate students, and medical professionals. Features •Interaction with the BoneBox™ Spine Viewer utilizes true real-time 3D, which allows the user to place the detailed spine model in any position and zoom in to explore all of the anatomical structures. •The user can view the labels of the full spinal column as well as the extensively labeled individual vertebra for a more detailed observation. Further study is accomplished by creating custom labeled pins, or by drawing directly on the spine, all in real-time 3D. •The user can explore the spine using a series of optional views. Color-coded, didactic models help to show the specific curvatures and regions of the spine, while selecting an individual vertebra will allow the user to explore the features of the single bone. •The interface color can be adjusted to a light or dark variation for better viewing and projection in multiple lighting conditions. •By turning on the color coded pins, the user can study the names and locations of over 100 anatomical structures, including: bones, foramina, and prominent anatomical features. The pins and labels remain on screen and in the exact anatomical location during all real time 3D user interaction. •Drawing with the multi-colored pen tool allows the user to draw directly on the surface of the 3D spine for use in the clinic, or classroom. •The BoneBox™ Spine Viewer is an excellent tool for any anatomy lecture or lab. Using the custom pin tool, instructors can place color-coded pins anywhere on the spine. Once placed, the instructor can write a question on the label of that pin. Students can then rotate the spine in 3D to gain a better understanding of that pin's location on the model. •The BoneBox™ - Spine Viewer is a must for any anatomy lecture or lab. By selecting to take the quiz, the user will experience an exciting, fully interactive feature that will test their knowledge of the bones of the vertebral column. As the bones randomly disperse around the screen, the user may select any bone and is prompted to correctly name that bone.

Primal's 3D Real-time Human Anatomy app for the Spine is the ultimate 3D interactive anatomy viewer for all medical educators, practitioners and students. Meticulously built over ten years from high-resolution cross-sectional photographs of real cadavers, the app provides an accurate and visually stunning reconstruction of the anatomy of the spine. The easy to use and intuitive interface lets you choose precisely the anatomy you want to see, from exactly the angle you want to see it. This flexibility is supported by a wealth of user-friendly tools to help you set up your ideal anatomical image, quickly and easily: • The Gallery contains 12 pre-set scenes, designed by an in-house team of anatomical experts, to clearly and comprehensibly present in-depth regional and systemic anatomy of the spine. Each scene is divided into five layers to provide greater control over the depth of anatomy shown; making tailoring the anatomy you want to see simple and quick. • The Contents folders arrange all 1,947 structures systemically, meaning you can browse by subcategory and switch all related structures on at once. It provides an excellent learning tool – for example turn on all branches of the vertebral artery, or the transversospinalis group of muscles. • The Contents layer controls split each system into five layers – from deep to superficial. This allows you to quickly build up different systems to the depth you want to see. **Save to Favourites** Save the views you create for later in the Favourites, save anything as an image, or share with another user as a URL link. Use the pins, labels and drawing tools to customize your images for enlivened presentations, engaging course materials and handouts – all from your iPad! **Informative** Read detailed and accurate text for each structure using the T icon, and in a feature unique to Primal Pictures, each anatomical term in the text is linked to the appropriate model in the 3D model. Selecting these links will highlight the relevant structures, bringing the text to life and make learning anatomy more visual and immediate. **Context** See each structure in context with the anatomy that surrounds it. Explore these relationships and easily navigate to related anatomical structures to expand your learning. Select a field name in the right-hand menu to show the anatomical category and sub-category of the structure for added understanding and simple navigation. **Technical Specifications** iPad 3 and above only. iPad Air and above for optimal viewing. iPhone 6 and above for best performance.
