INTRODUCTION.
OpenVision™ DX is an easy to use, digital X-ray system with live video output for real-time radiographic 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
external defects as small as 0.010-inch (250 μm) on insulated piping.
OpenVision DX can be used on various insulation and cladding combinations, including mineral wool and calcium silicate
with galvanized steel, stainless steel, and aluminum cladding up to 36 inches (91 cm) in total diameter.
OpenVision DX enables the inspection of hundreds of feet (many tens of meters) of insulated piping to quickly identify
indications of corrosion or corrosion precursors such as scaling, external wall loss, and wet insulation. 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™ DX system or components of the system.
It is important that trained and qualified personnel perform or supervise a daily safety inspection of the OpenVision
DX system for obvious defects before using the system. Do not compromise on safety. Always perform the daily
inspection of the system 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 DX system or any after-market
component as they may compromise the safety features designed into the system.
Defective equipment that is discovered during the daily inspection must be removed from service until repaired or
replaced.
The user of this equipment must follow the 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.

Page 7 of 33
Operating Conditions
OpenVision™ DX is designed for applications where the equipment will not be exposed to harsh handling or environmental
extremes. See Equipment Specifications for more information
X-Ray 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 any laser towards an aircraft or vehicle in motion.

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.

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 11 is positioned in this approximate area.
Figure 11 OpenVision DX Output Boundary Distances
Figure 11 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 (see Figure 31 on page 28, item #415230, not shown in Figure 11) provides shielding to either
side of the imager when the specimen being imaged (e.g., small piping) 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 12 Example Scatter Radiation Survey
Figure 12 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 12 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.

Page 17 of 33
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 13) will help reduce the amount of backscatter when firmly applied to the scanning
surface as shown in Figure 15.
Figure 13 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.
