What is darkroom in radiography?
The latent image produced when a radiographic film is exposed to a beam of X-ray can be visualized and examined only after the film has been suitably processed in the dark room. Too large room is as undesirable as small room. Dark room should be near the x-ray examination area.
What is portable radiography?
What is Portable Radiography? Depending on the size of a hospital or medical center, there is one or a team of radiologic technologists who use portable radiographic and fluoroscopic equipment to go to patients when patients cant come to the imaging department. Radiograph of a broken arm.
Why is it called the darkroom?
Its called a darkroom because it is almost completely dark – apart from a red light called a “safe light”. This is really important because it allows you to handle the light-sensitive materials necessary to make traditional darkroom prints.
What is dark room in medical?
(dahrkrūm) Enclosed area or chamber dimly lit by safelight (usually red) but otherwise intentionally lightproof room where films are handled and processed.
What is darkroom process?
A darkroom is used to process photographic film, to make prints and to carry out other associated tasks. From the initial development of the film to the creation of prints, the darkroom process allows complete control over the medium.
What is darkroom illumination?
In photography, the term “safelight” describes darkroom illumination that does not fog or otherwise cause a visible change to light-sensitive material when it is correctly handled and processed. The word “safe” is relative.
What is the difference between mobile and portable?
1 Answer. Portable – capable of being [easily] transported or conveyed. E.g. a laptop computer is a portable device (compared to a desktop device which can be moved only with some difficulty). Mobile – capable of moving or being moved readily.
What are the advantages of portable radiography and fluoroscopy?
Portability Increases workflow efficiency. Increases the number of patients that can be seen. Makes visits easier on injured or very ill patients. Allows doctors to visit patients off site in cases where patients are in conditions that would prevent or hinder them from traveling to a facility.
How does a darkroom work?
Darkroom equipment In most darkrooms, an enlarger, an optical apparatus similar to a slide projector, that projects light through the image of a negative onto a base, finely controls the focus, intensity and duration of light, is used for printmaking.
What are darkroom techniques?
Darkroom manipulation is a traditional method of manipulating photographs without the use of computers. Some of the common techniques for darkroom manipulation are dodging, burning, and masking, which though similar conceptually to digital manipulations, involve physical rather than virtual techniques.
What is the purpose of darkroom?
A darkroom is used to process photographic film, to make prints and to carry out other associated tasks. It is a room that can be made completely dark to allow the processing of the light-sensitive photographic materials, including film and photographic paper.
What are the criteria for darkroom?
There should be a positive pressure in the darkroom, drawing air in through a vent in the door. The return duct should have at least four bends between the grill in the darkroom and a grill in another room in order to prevent light fogging of the film due to reflected light.
