"A 4D Design is the dynamic form resulting from the design of the behavior of artifacts and people in relation to each other and their environment". (Robertson 1995).

4D CINEMA is a complete and complex solution for 3D video animation that gives you total power and control throughout the whole design and creation process.
4D as a technology is based on the 3D platform. It combines the effect of 3D movies by incorporating external physical effects like movement in seats and environmental enhancers like virtual fog, rain, lighting, air bubbles and smells in the movie watching experience. "This will enable audiences to have both visual and sensory experience and create a never before experience," the company said in a release
4-D film is a marketing term that describes an entertainment presentation system combining a 3-D film with physical effects in the theatre, which occur in synchronization with the film.
capsule simulator- where the audience is fully enclosed
above the motion system and where the audio visual system moves with the motion. Such simulators are used usually in smaller outdoor locations and usually are configured around simple 2D or 3D display systems.
auditorium based environment-Such systems are
usually used in high capacity applications of
typically 20 to 100 seats.

The CAVEman Project aims to create visual maps of information about diseases that have a genetic component, such as cancer, diabetes, and Alzheimer's. Using an immersive virtual reality environment called the CAVE, the research teamwill integrate a high-resolution digital atlas of a human body with medical data related to specific diseases.
”4D Building model: a conceptual system of the dimension of time in building’s life” is the concept of a web-based interface of a databank that stores and visualizes information of the building’s life process.

4D ultrasound is a medical ultrasound technique, often used in obstetric ultrasonography (during pregnancy), providing
4 dimensional images of the fetus.
High-frequency sound waves (MHz) Medical imaging technique: use of sound waves to
visualize internal structures Basic concept: transducer sends out sound waves Sound waves reflect off of internal structures Image generated from data: Time for the echo to be received Intensity of echo Depends on density of material, location in body Different types: 1D, 2D, Doppler, 3D, 4D
Accuracy and repeatability Less dependent on technician’s ability to
visualize 2D images in 3D setting Easier to track growth of tumours
/diseases, lesions No health risks from moderate use Potential health problems Too intense Over-usage Useful to see structures in motion Surgery Diagnosis
3D Imaging during surgery,
radiotherapy planning Find instruments with
respect to structures in the body
Looking at structures / sections of larger structures
Eg: fetal screening, breast biopsy, carotid artery, intestine, eye, intravascular, rectal, gynaecological
4D Fetal screening Echocardiography
