1. the act of viewing or of achieving a complete visual impression of an object.
2. the process of forming a mental picture of something.


1. The act or process of visualizing.
2. The use of mental images to influence bodily processes, control pain, or prepare for athletic or other kinds of performance.


an effective means of deepening relaxation and desensitizing a real-life situation that is generally met with stress and tension. The imagery combines positive experiences with actual or perceived negative events or situations in an effort to desensitize the person to the trauma. Also called guided imagery, visual imagery.


The process of making an internal organ visible. A radiopaque substance is introduced into the body, then an x-ray picture of the desired area is taken.


n structured technique in which the individual uses his or her imagination to create images of desired life changes. See also relaxation and visualization.


1. The ability to form a mental image of an object not present in the field of view.
2. Synonym for imagery. Example: visualizing the face of a person speaking on the radio. See imagery.


the act of viewing or of achieving a complete visual impression of an object.

Patient discussion about visualization

Q. Can visual aura alone be migraine? I'm 21 years old girl, and for the last six years, about once a week, when I wake up from night sleep all I see in my left eye is a very bright light. After some time my vision returns. In the last few weeks it became more frequent and also starts to happen in the other eye. I consulted my doctor and she told me it's not an important thing, and that it's probably a specific type of migraine. However, I don't have any pain at all. Does anyone else have this? Is it possible for migraine to occur only with aura, without any pain?

A. Hi,

I'm sorry to hear about your problem. Whatever your doctor told you, you should know that if it bothers you, it IS an "important thing". I also suffer from similiar thing (only visual disturbances after I wake up, without any pain), and when my doctor prescribed me meds they went away. You should consult your doctor again and ask him for a solution for this thing.

Q. What are the visual distinctions between thermal burns and frostbite? Is it possible to definitively distinguish the two from each other in all cases, or do they present identically in many cases? In other words, are frostbite injuries-for all intents and purposes, actual burns and if they are not, in what ways do they differ?

A. Early frostbite and minor burns may resemble one another visually (by whitened, blanched looking skin, and blister formation). However, last stage frostbite and thermal (heat) burns are very different.
In late stage frostbite, the ice crystals in the cells melt and the ruptured cells pour out their contents, then blisters may form. Since the affected area has basically lost circulation, gangrene sets in rather quickly and the tissue turns black and dry.
Deep (full thickness) heat related burns are surrounded by areas of erythema (reddened skin) and skin with less degrees of burning. Also, eschar is obviously charred skin tissue forming a scab like structure, and looks nothing like gangrene. The wound bed in a burn leaks plasma constantly. Blistering is pretty immediate with heat related burns of a sufficient degree.

While many teachers were already using scientific visualizations in their teaching, they were doing it in the face of considerable constraints.
While evaluating the effectiveness of learning with scientific visualizations for all students is valuable, it is also plausible that this teaching approach might be more or less effective for particular students.
As a complement to the SC11 Scientific Visualization Gallery, The University of Texas booth is featuring a first-of-its-kind creation by Kelly Gaither's team back at TACC: Namely, a "Vislab" multi-touch display run by a single AMD Eyefinity node with six 46" monitors in a 2X3 grid configuration.
It straddles the worlds of scientific visualization, presentation graphics, and Hollywood-style animation--providing the precision, accuracy and power to process large scientific data sets, then presenting them in a visually stunning form that informs as well as entertains.
Precomputation or data-buffering strategies do not address these problems in an interactive real-time scientific visualization application, as there is no a priori information about what kind of visualization the researcher will be using and what data will be accessed.
However, the problems addressed in real-time scientific visualization will far outstrip the advances in technology.
Probably no other area has had as much an impact from scientific visualization efforts over the past five years than has molecular modeling.
The workshop discussion prompted Welling to propose and circulate a set of guidelines for doing scientific visualization.
The result is greatly expanded access to powerful scientific visualizations and increased productivity for both local and remote users.
It has emerged as a interdisciplinary discipline in the neighborhood of machine learning, computer vision, neural networks, pattern recognition, image processing, graphics, and scientific visualizations.
