Region of interest fluoroscopy

Medical Physics, 1992
In some medical imaging applications, it is necessary to visualize only the center of the field of view with optimal quality. For example, often in interventional radiographic procedures only the region directly adjacent to the catheter tip must be well seen.

ALARA in Pediatric Fluoroscopy

Journal of the American College of Radiology, 2007
hildren are not small adults. First, heir disease states are different rom adults, which may necessitate ore imaging examinations. For xample, congenital heart and vasular defects in neonates and inants can require up to 10 cardiac atheterizations, as opposed to 1 inervention required for coronary arery disease in adults [1].

Stereoscopic Televised Fluoroscopy

Radiology, 1962
The possibilities of stereoscopic roentgenography were appreciated by the early roentgenologists. Two roentgenograms of a patient made with the x-ray tube displaced a few inches at right angles to the direction of the central beams were viewed in a stereoscopic illuminator. Each roentgenogram was presented to the respective eye.

ERCP and Fluoroscopy Time

American Journal of Gastroenterology, 2014
To the Editor: We read with interest the study of Romagnuolo and Cotton (1). The study reported different factors that predict prolonged fluoroscopy time (FT) during endoscopic retrograde cholangiopancreatography (ERCP) (1). In our multicenter study (n=414, ERCP procedure performed by six endoscopists in three American centers) that was partially ...

Television fundoscopy and fluoroscopy

Journal of Audiovisual Media in Medicine, 1980
Systems have been developed using an inexpensive colour television camera and a specially designed high sensitivity monochrome camera to enable fundoscopy and retinal fluoroscopy to be carried out using TV as the recording medium. The advantages and details of the techniques are described.

An Adaptometer for Preparation for Fluoroscopy

Radiology, 1951
Every fluoroscopist has a method of determining when his eyes are dark-adapted; he wears goggles for a timed period, gauges his eyes by a light leak in the room, or perhaps switches the tube on and off until satisfied. Presented here is a low brightness adaptometer which will take the guess out of this chore.

The Scintillation Limit in Fluoroscopy

Radiology, 1954
The ultimate performance which can theoretically be obtained with a fluoroscopic imaging device is determined by the quantum nature of the x-rays themselves. In medical fluoroscopy, the available x-ray intensity is set by the permissible patient dose, so that the information carried by the x-rays is quite definitely limited. This fact was first pointed
