Manipulating Images
The IDEXX EquiView
®
software allows for certain settings to be adjusted to change the appearance
of the “first view.” The first view is the image that appears on-screen after these automatic
settings are applied. You can then manually change window and level settings and apply other
functions, such as edge enhancement when looking for a stress fracture. During installation, your
IDEXX representative will adjust the appearance of the first view to suit your preference and the
performance of your X-ray generator.
After the image is taken, you have a full range of tools to use to manipulate the image. Images
already taken are automatically stored and sequentially numbered in accordance with the
presettings made by you. You can take all relevant images, and then optimize the settings for the
images and make the diagnosis.
Dynamic Views
The mathematical treatment of the raw data from the plate is a very complex combination of
functions known as an algorithm. IDEXX has developed an algorithm that shows some soft-tissue
features while still allowing you to view dense bone detail. This is one of the features that makes the
EquiView Digital Radiography System unique.
Window and Level Adjustments
The Window function is a representation of the amount of image data viewed at one time
(contrast). The Level function is a measure of the relative luminance of the pixels within the
window (brightness). The Window and Level functions adjust the contrast and brightness as a
secondary function to the primary purpose of making various structures in an image visible on
the screen. Window and Level both have a numeric value that is displayed in the middle of the right
border of the active viewing window.
