The Image Wisely campaign is creating a Web site that will target each of the major stakeholders in imaging: imaging professionals (comprising radiologists, other practitioners who use medical imaging, medical physicists, and radiologic technologists), referring practitioners, and patients and the public.
What is the difference between Image Gently and Image Wisely?
Since that time, the Image Gently Alliance, which focuses on children, and the Image Wisely campaign, which focuses on adult patients, have made significant inroads into the education of radiologists, technologists, referring physicians and the public, with a goal of decreasing unnecessary radiation exposure by
What is the Image Gently campaign?
The Image Gently campaign was launched in 2008 to raise awareness about methods to reduce radiation dose during pediatric medical imaging exams.
What is the blurred margin of an image?
–The blurred margin at the edge of objects produced by a finite focal spot is called a penumbra. –The penumbra is the result of x-rays arriving from slightly different locations in the focal spot. –The resultant loss of sharpness is called focal spot blur or geometric unsharpness.
Why is a radiographic film coated on both sides?
Putting emulsion on both sides of the base doubles the amount of radiation-sensitive silver halide, and thus increases the film speed. The emulsion layers are thin enough so developing, fixing, and drying can be accomplished in a reasonable time.
What is Xray film made of?
A modern x-ray film consists of a radiation-sensitive emulsion coated on a transparent polyester base. The emulsion consists of silver halide crystals (typically 95% silver bromide and 5% silver iodide) and gelatin which provides the suspension medium for the silver halide grains.
Which modality was the initial focus of the Image Gently campaign?
The Image Gently campaign has created educational information for each ionising radiation modality (CT scan, fluoroscopy, radiography, nuclear medicine, interventional radiology and dental imaging), beginning with CT scans.
What is the main goal of image gently?
The Image Gently Alliance is a coalition of health care organizations dedicated to providing safe, high quality pediatric imaging worldwide. The primary objective of the Alliance is to raise awareness in the imaging community of the need to adjust radiation dose when imaging children.
Why is image gently important?
Image Gently advocates methods to reduce the use of unnecessary ionizing radiation by sharing best practices of imaging protocols for children and using alternative imaging that avoids ionizing radiation.
How did Image Gently begin?
The ultimate goal of the Alliance is to change practice.
The Image Gently Alliance began as a committee within the Society for Pediatric Radiology in late 2006.
What is high contrast resolution?
High-contrast resolution is the ability to detect finely spaced lines or holes with whose signals differ considerably from background. Low-contrast resolution is the ability to detect and discern objects with only subtle differences in signal intensity.
Will improve the sharpness of a radiographic image?
Thicker intensifying screens increase the sharpness of extraoral radiographs. The target-object distance is the distance between the focal spot on the target and the skin surface of the patient. Only one film should be placed in contact with the intensifying screens used for extraoral radiography.
Why would an xray be blurry?
Due to the finite size of the focal spot, when the object is further away from the detector, the edges in the image of the object get blurred (Penumbra).
What does the kVp control?
kVp controls the penetrating strength of an x-ray beam (beam quality). Whenever an exposure is made, the x-rays must be energetic (strong enough) to adequately penetrate through the area of interest. The higher the kVp, the more likely the x-ray beam will be able to penetrate through thicker or more dense material.
What is periapical film?
A periapical x-ray or “PA film” will show one or two teeth in their entirety in one single image, right from the crown of the tooth which is the part exposed in the mouth to the very tips of the tooth roots located in the jawbone, as well as the surrounding bone supporting this tooth.
What is the overall darkness or blackness of a radiograph?
Density is the overall darkness (blackness) of an image. Contrast is the difference in lightness and darkness between areas on a radiograph.
