Visualizable objects in biology and medicine extend across a wide range of scale, from individual molecules and cells through tissue varieties and interstitial interfaces to whole organs, organ systems, and body parts.

The practice of medicine and the study of biology have always been based on visualisations to study the relationship between anatomical structure and biological function and to detect and treat diseases and injuries that disturb or threaten the processes of normal life. Traditionally, these visualisations have been direct, through surgery or biopsy, or indirect, requiring extensive mental reconstruction. The potential for revolutionary innovation in medical practice and biological research lies in the direct, fully immersive, multi-sensory, real-time, real-time online data flow visualisation available during clinical procedures Real or biological experiments. In the field of scientific visualisation, the term "four-dimensional visualisation" generally refers to the process of representing a three-dimensional field of scalar values.

"4D" is the abbreviation for "four dimensions" - the fourth dimension is time. The 4D display takes three-dimensional images and adds the time element to the process. The revolutionary capabilities of the new three-dimensional (3-D) and four-dimensional (4-D) medical imaging modalities along with computerised reconstruction and multidimensional medical and histological volume imaging data avoid the need for physical dissection or Abstract assembly of Anatomy and provide new and potent opportunities for medical diagnosis and treatment as well as for biological investigations. In contrast to 3D diagnostic imaging processes, 4D allows the physician to visualise the internal anatomy by moving in real time. Thus, doctors and sonographers can detect or rule out any number of problems, from vascular anomalies and genetic syndromes. Time will reveal the importance of the 4d display.
