INTRODUCTION.
OpenVision™ DX is an easy to use, digital x-ray system with live video output for real-time inspection and reporting. A
patent-pending combination of a c-arm mounted 70 kV x-ray source and a digital imager allows you to observe features
as small as 0.010-inch (250 μm).
OpenVision DX can be quickly setup and deployed. Pictures and real-time videos are recorded and downloaded with the
touch of a button for rapid review and reporting.

SAFETY PRECAUTIONS.
WARNING
Do not perform any unauthorized modifications to the OpenVision™ system or its components.
It is important that trained and qualified personnel perform or supervise a daily safety inspection of the
OpenVision system for any defects. Do not compromise on safety. Always perform daily system inspections
prior to use.
Any foreign material (dirt, mud, ice, etc.) must be removed before using the system. Inspect, clean, and test the
equipment as described in this manual to ensure long-term safety and reliability.
Do not use any component that is not approved for use with the OpenVision system or any after-market
component. Doing so may compromise the safety features designed into the system.
Defective equipment that is discovered during daily inspections must be removed from service until repaired or
replaced.
Equipment operators must follow all operating instructions, in the order shown, to ensure safe operations and
compliance with government regulations.
Personnel operating this equipment must be completely familiar with this manual and they must read and understand
these important safety alerts before proceeding:
IMPORTANT SAFETY ALERTS
NOTICE: Can cause minor problems and reminders.
CAUTION: Can cause equipment damage or potential problems.
WARNING: Can cause serious or fatal injury.
WARNING: JOB SITE SAFETY PRECAUTIONS
Surveillance
Only trained and qualified individuals, or assistants working under their direct supervision, may operate the
OpenVision DX system. The qualified individuals must be physically present at the site and able to control and
limit access to the vicinity of the work.
Locking
Keep the OpenVision DX controller locked while assembling the system and when not being used to perform
scanning. Locked is defined as the controller key switch in the Off position with the key removed. Store the key in
a secure location.

Operating Conditions
OpenVision™ DX is designed for applications where the system will not be exposed to harsh handling or environmental
extremes. See System Specifications for more information.
Training
It is required that OpenVision DX operators are properly trained and qualified to perform radiographic inspections. This
manual does not address radiographic inspection techniques or procedures.
Precautions
The OpenVision DX system is designed for portability and is ruggedized for industrial environments. However, it does
contain fragile components. Use care to avoid strong vibrations and shock conditions (e.g. equipment drops or
transportation outside the approved case) to the main housing, imager housing, and display(s).
CAUTION
Do not attempt to open or modify the imager housing, main housing, or X-ray tube. Opening any of these
components will void the system warranty and may expose the operator to a high voltage shock hazard.
CAUTION
Do not allow liquids to come into contact with any part of the OpenVision™ DX system. The main and
imager housings have been made water resistant, but they are not “Waterproof”. Appropriate care should
be taken to protect all cabling and connectors to ensure reliable and safe operation of the OpenVision DX
system.
WARNING: CLASS 2 TARGET LASER
Because the blink reflex (glare aversion response to bright lights) will limit the exposure to no more than 0.25
seconds, Class 2 laser pointers are considered to be safe. Furthermore, Class 2 lasers do not harm eyes
unless a person deliberately stares into the beam, making laser protective eyewear not necessary. A Class 2
laser is not a skin or materials burn hazard. NEVER aim an
y
laser towards an aircraft or vehicle in motion.

Figure 5 Monitor - Front View
The OpenVision DX monitor is powered by both an external or internal battery. The external battery charger (Figure 7)
can charge two batteries. The internal battery is charged with either a 12-volt DC charger connected to the power input
jack (Figure 6, Item #5), or with the external battery (Figure 6). The charging indicator will turn RED while charging
(Figure 5, Item #2), and GREEN when monitor is on.
NOTICE
The monitor’s DVR functionality is not compatible with the DX system. Image/video recording
is handled directly within the DX system software.

PRINCIPLES OF OPERATION.
Radiography uses X-rays or gamma rays passing through a specimen onto an imaging medium (film, digital imager,
imaging plate, etc.) on the opposite side. The quality and quantity of radiation reaching the imaging medium is largely
determined by the object’s thickness and density. Radiation energy (X-ray = kV; Gamma Ray = isotope) governs its
penetrating power. Radiation intensity is governed by current (milliampere or mA) for X-rays, and by content activity
(Curie/Becquerel) for radioisotopes.
Radiographic Quality
Radiographic quality depends on an image’s photographic (density, contrast) and geometric (definition, distortion)
properties. Proper energy and intensity selection are both essential for producing high-quality radiographs.
Sources (X-Ray & Gamma Ray)

Higher isotope energy = increasing
penetrating capability:
Co-60 > Cs-137 > Ir-192 > Se-75
Higher Ci = more disintegrations of nuclei =
more gamma rays
Simplified Exposure Determination with X-Rays
By using X-rays, the OpenVision™ DX system has the advantage of real-time radiography (immediate availability of
images). Time calculations (as used in gamma-ray radiography exposure) are not needed for X-ray radiography.
To determine exposure requirements, start on the lowest kV and mA settings and adjust to achieve the desired image
quality.

RADIATION ZONES.
Output Radiation Levels
OpenVision™ DX radiation levels vary depending on kV/mA settings. QSA Global, Inc performs testing at maximum
power at the highest kV setting (70 kV, 0.17 mA) to verify collimation and image quality. Operators must be aware of safe
boundary distances while using the OpenVision DX. When the main housing is fully expanded (“D” = 53 cm [20.8 in]), the
most susceptible area of high dose rate (when specimens do not block entire X-ray output beam) is immediately adjacent
to imager housing. The “C” callout in Figure 8 is positioned in this approximate area.
Figure 8 - OpenVision DX Output Boundary Distances
Figure 8 shows boundary distances for 2, 0.75 and 0.25 mR/hr. Table 3 below details typical distances for these
boundary levels with different operating conditions.
NOTICE: The imager shield (not shown in Figure 8) provides shielding to either side of the imager when the specimen
being imaged (e.g., small objects) does not completely attenuate the X-ray output.

Actual measurements can vary based on the material being scanned and its geometry. To minimize operator exposure,
QSA Global, Inc. recommends using a backscatter shield assembly (Item # 415600) with your OpenVision DX.

Figure 9 Example Scatter Radiation Survey
Figure 9 shows an example survey of backscatter radiation (user exposure) for a typical sample (NOTICE: for reference
only; actual readings may vary). The example survey shown in Figure 9 was created with the following conditions:
8 in steel pipe
2 in calcium silicate insulation
.040 in [1 mm] thick aluminum cladding
70 kV @ 0.17 mA (maximum power at the highest kV level)
See the following section for additional information on backscatter.

Backscatter
Backscatter occurs when X-rays interact with material (piping, insulation, etc.), potentially travelling in undesirable
directions (e.g. towards the operator). Backscatter is dependent on many variables including geometry, material, and
energy level. It can potentially increase the dose to the operator’s extremities.
The best way to minimize backscatter is to use the lowest kV / mA combination to achieve acceptable images. Use of the
optional backscatter shield (Figure 10) will help reduce the amount of backscatter when firmly applied to the scanning
surface as shown in Figure 10.
Figure 10 - Optional Backscatter Shield (Item #415600)
CAUTION
Whenever scanning an unknown material and/or geometry, it is recommended that operators monitor for
backscatter levels to minimize operator dose.
