Getting Started
Overview
The IDEXX EquiView® Digital Radiography System is a high-resolution digital X-ray system that generates X-ray images without films and chemistry. The digital X-ray plate is exposed by a diagnostic X-ray apparatus and the X rays are then directly converted into electrical signals. These signals are read by the X-ray generator and then converted into images by the EquiView software and displayed on the monitor.
The images created by the EquiView software allow you to view both bone and soft tissue structures in one image with one single exposure. You can easily view and enhance relevant areas and structures for diagnosis. In addition, areas of an image can be enlarged up to three times without significant pixelization. Radiography System diagnostic purposes.
Components
The basic components for the IDEXX EquiView Digital Radiography System consist of a computer, a digital X-ray plate, two switch boxes, a trigger, and a remote control. These components form a compact system for taking, processing, and archiving digital X-ray images.
Computer
The portable, Microsoft® Windows®-compatible computer runs the archive the image files created from the digital X-ray plate.
EquiView software, which
Because of the high quality of the monitor, the

Digital X-ray Plate
The digital X-ray plate is an ultracompact, portable plate for use in place of a regular film cassette, and can be used with any X-ray source generally available
(portable sources should have a high-frequency, full-wave rectification (e.g., Gierth 80 HF ultralight)
.
The plate generates digital X-ray images without using X-ray film or foil. The X rays are converted directly into an image and displayed on the
Cable
computer. The direct conversion of the X rays into electrical signals without the use of a scintillator absorbs less energy, thereby reducing blurring. As a result, the various structures are better differentiated so that images are sharper and provide greater detail.
The plate’s active imaging
surface is 20 x 25 cm (8 in x 10 in).
Switch Boxes
The switch box is the interface between your X-ray generator and the IDEXX EquiView Digital Radiography System computer. There are two switch boxes—one for the manual trigger setup and one for the remote control setup. Be sure you are using the correct switch box for your desired setup.

Setting Up the IDEXX EquiView® Digital Radiography System
Ensure that all components are present. Keep the packing materials in a dry place in case you need them later.
CAUTION: The room temperature must not drop below 5°C (40°F) and must not rise above 35°C
(95°F). There is a risk that the active layer of the digital X-ray plate can be destroyed.
CAUTION: When the EquiView Digital Radiography System is taken out of a cold environment and
put into a warm room, condensation may form. In this case, the equipment must not be connected to an electrical source because there is a risk of damage. Wait until the EquiView Digital Radiography System has warmed up to the ambient temperature and condensation has completely dried. This may take several hours.
The initial installation may only be carried out by suitably qualified personnel.
Initial Installation
You can configure your EquiView Digital Radiography System to use a manual trigger or a remote control to take X rays. Decide which configuration you prefer before beginning the initial installation.

start over again, or select another horse.
4. Click the Take Images button at the bottom of the screen to open the Take Images screen and begin to take X rays.
Taking X rays
The EquiView Digital Radiography System has a very large dynamic range, which means that careful technique setting is no longer a necessity, with certain exceptions. The most likely error that can occur is underexposure, in which only a part of the dynamic range of the digital X-ray plate is used. In this case, especially bony structures appear significantly less structured and there is a risk of losing important information about these areas.
Choose Exam Types screen
Special X-ray Views
Thick body parts: AP Stifle, Neck, and Spinous Processes. These thick body parts are at the limit of penetration for the small handheld generators. However, the EquiView Digital Radiography System is still able to produce good quality images provided some important points are kept in mind.
Thick body parts produce a large amount of scatter, which tends to fog the image. Due to the
high dynamic range of the EquiView to scatter. This means in practice that there is a limit on thick body parts where increasing mAs

becomes limiting and does not improve image quality after a certain level.
TIP: Moving the X-ray source closer to the body part, which increases the effective kVp, may
have a better impact on the image than simply continuing to increase mAs.
Equine foot: The equine foot is another body part that produces a great deal of scatter. To
produce good images of the navicular bone, similar techniques to the above may be helpful. A grid is always helpful for images where a grid can be easily used, in respect of maintaining the geometric requirements. In addition, lead shielding of unwanted parts of the image can be helpful.
To expose the plate:
1. Place the digital X-ray plate into your X-ray equipment’s holder for film cassettes or in another
suitable position. The plate’s active imaging surface must face the radiation source.
2. Select suitable settings on your X-ray equipment for exposure time and accelerating voltage.
WARNING: National regulations for dealing with X-ray radiation and the operation of X-ray
devices applies. Do not exceed the applicable national standards for the radiation doses. Pay particular attention to the safety of the personnel in the vicinity of the X-ray equipment.
TIP: Use high kV and low exposure time. Dose increases proportionally with the kV, but to
second order with time.
TIP: Using old generators that do not have full-wave rectification and have exposure times
over 0.2 seconds is not ideal. If you have been using a good quality X-ray generator in the past, setting kVp at 80 and mAs at 1.8 is ideal for most exams.
TIP: Most X-ray generators have a milliamperage of 15 mA, so the time factor would be set to
0.12 seconds: 15 mA x 0.12 s = 1.8 mAs. For large structures, 80 kVp and an mAs-product of 15 mA x 0.25 s = 3.75 mAs can be used.
3. Ensure that the desired structures are located between the X-ray source and the digital X-ray
plate. The plate must be aligned vertically to the direction of incidence of the X-ray beams. The film-focal distance (FFD) should be in the range of 55–60 cm (21.6"–23.6").
TIP: The X-ray generator should be placed closely to the region of interest.
TIP: Movement artifact is usually a combination of movement of the X-ray source, the horse
and the plate itself.
4. Press and hold the exposure switch halfway down until you hear the beep indicating that the
plate is ready for an exposure. This prepares the generator and plate, and can take up to 4 seconds. In addition to the beep, the light on the plate turns from green to red, and a blue progress bar appears at the bottom of the computer screen and moves halfway across.
IDEXX EquiView® Digital Radiography System Operator’s Guide 9
5. After any of these signals, fully press the switch to take the image. The computer beeps, the blue progress bar continues across the computer screen, and the light on the plate changes from red to green.
6. The processed image appears on the monitor within 12–15 seconds. The next image can be taken after 5–8 seconds, when the 20-second cycle time of the plate has elapsed.
Skipping an Image
The EquiView software looks for the first unchecked check box in the Examination section and associates the image to be taken with that view. You can skip image views (if necessary or desired) by selecting the check box next to that particular image.

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. border of the active viewing window.

X ray of a hock
If you “window” and “level” a typical image, you can view individual hairs on a limb while still being able to “window” back to dense subchondral bone detail. With film, this is generally very difficult, and it is standard practice to take two different exposures to identify subchondral bone features of the distal condyles of MCIII and a second lower-energy setting to identify any possible osteophyte or enthesiophyte formation around the joint. The dynamic range of the digital X-ray plate and the EquiView software allow all these details to be seen in one image.

IDEXX EquiView® Digital Radiography System Operator’s Guide 23
Transportation and Storage
The active imaging surface of the digital X-ray plate is sensitive to temperature. To ensure safe transportation and storage of the digital X-ray plate, always transport and store the plate in the supplied case. Connect the digital X-ray plate to a power supply (Connector 1) or to the 12-volt electrical system (Connector 2) of your vehicle as shown in the diagram, and turn on the temperature control. This ensures that the plate is always transported and stored in the optimum temperature range.
CAUTION: At temperatures below 5°C
(40°F) or above 35°C (95°F), changes to the surface can occur. At temperatures above 40°C (104°F), depending on time and temperature, irreversible changes will take place.
If the ambient temperature rises above 27°C (80°F) or falls below 10°C (50°F), make sure the case is connected to a main power supply or to the 12-volt electrical system of your vehicle and is turned on. The plate can be used in the extreme temperatures as long as it is placed into the case between taking shots.
A combined heating and cooling element (Peltier element) is installed in the transport case, and insulation ensures that the temperature within the case changes very slowly. The red LED indicates temperatures below 15°C (60°F) and the temperature control module has automatically turned on the heating. The green LED indicates temperatures above 35°C (95°F) and the cooling is active. If the temperature range is above 15°C (60°F) or below 35°C (95°F), none of the LEDs light up; the temperature in the case is within the allowable temperature range and is displayed on the temperature control module. When heating or cooling is active, the temperature control module will keep heating or cooling until a temperature of 25°C (77°F) is reached in the case.
