![]() Many life-threatening diseases and/or quality-of-life afflictions still require physical interventions into the body to reduce or remove disease or to alleviate harmful or painful conditions. For example, both realism-preserving and perception-modulating approaches to image display have significantly advanced the practical usefulness of 4-D biomedical imaging. A variety of both standard and sophisticated methods have been developed to process (modify) images to selectively enhance the visibility and measurability of desired object features and properties. Efforts to unlock this information to reveal answers to the mysteries of form and function are couched in the domain of image processing and visualization. Locked within 3-D biomedical images is significant information about the objects and their properties from which the images are derived. So physicians and sonographers can detect or rule out any number of issues, from vascular anomalies and genetic syndromes 3D GIVES LIFE TO 4D: For example: Movement patterns of fetuses allows conclusions to be drawn about their development increase of accuracy in ultrasound guided biopsies thanks to the visualization of needle movements in real time in all 3 planes. In contrast to 3D imaging diagnostic processes, 4D allows doctor to visualize internal anatomy moving in real-time. 4D visualization takes three-dimensional images and adds the element of time to the process. "4D" is shorthand for "four-dimensional"- the fourth dimension being time. Time will reveal the importance of 4d visualization 4D-THE MODERN DIMENSION So physicians and sonographers can detect or rule out any number of issues, from vascular anomalies and genetic syndromes. ![]() The revolutionary capabilities of new three-dimensional (3-D) and four-dimensional (4-D) medical imaging modalities along with computer reconstruction and rendering of multidimensional medical and histologic volume image data, obviate the need for physical dissection or abstract assembly of anatomy and provide powerful new opportunities for medical diagnosis and treatment, as well as for biological investigations.In contrast to 3D imaging diagnostic processes, 4D allows doctor to visualize internal anatomy moving in real-time. In the field of scientific visualization, the term "four dimensional visualization" usually refers to the process of rendering a three dimensional field of scalar values. The potential for revolutionary innovation in the practice of medicine and in biologic investigations lies in direct, fully immersive, real-time multi sensory fusion of real and virtual information data streams into online, real-time visualizations available during actual clinical procedures or biological experiments. Traditionally, these visualizations have been either direct, via surgery or biopsy, or indirect, requiring extensive mental reconstruction. I'm already imagining the world's burgeoning math wizards playing inside of 4D Toys' robust playsets and discovering the coolest answer to the age-old question, "why should I care about math?" And if my time with the app is any indication, its helpful text and open-ended zaniness should lead adults through similar fits of childlike wonder.The practice of medicine and study of biology have always relied on visualizations to study the relationship of anatomic structure to biologic function and to detect and treat disease and trauma that disturb or threaten normal life processes. I am not sure that I've ever seen a more compelling "show-don't-tell" educational tool than 4D Toys. Once I realized this, and flung a ball over a toy-like string, I squealed when I warped through the fourth dimension to follow that ball on its sliding journey. ![]() Some of the toys let you grab and fling things within the dimension that you perceive, but they are still able to move and transform through other dimensions. As you glide across the fourth dimension via a finger swipe, the three-dimensional objects in your field of view transform, since you can only see a single slice of their full 4D form at any given time. With the tutorial complete, I sat down in real life so I could get my hands all over the app's densely lined floor of toys. I've snapped some screens of what I discovered, though they don't quite do their in-game counterparts justice. and can look quite different as you move along the fourth dimension.
