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™ 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 “Water Proof”. 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.

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)
Radiation

Energy
(Quality)
Intensity
(Quantity)
X-Ray
Determined by voltage (kV)
Higher kV = shorter wavelength = higher

Determined by tube current (mA)
Higher mA = more electrons = more X-rays
Gamma Ray
Determined by type of radioisotope (keV or
MeV)
Determined by radioactivity (Ci/Bq): Gamma
Rays produced by unstable nuclei

Higher isotope energy = increasing
penetrating capability:
Co-60 > Cs-137 > Ir-192 > Se-75
Higher Ci = more disintegrations of nuclei =
more gamma rays
Table 2 Radiation Comparisons
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/mA settings and adjust to achieve the desired image quality.

RADIATION ZONES.
Output Radiation Levels
OVDX radiation levels vary depending on kV/mA settings. QSA performs testing at maximum power (70 kV, 0.17 mA) to
verify collimation and image quality. Operators must be aware of safe boundary distances while using the OVDX. When
the main housing is fully expanded (“D” = 53cm [20.8in]), 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 3 is positioned in
this approximate area.
Figure 3 OVDX Output Boundary Distances
Figure 3 shows boundary distances for 2, 0.75 and 0.25mR/hr. Table 3 below details typical distances for these boundary
levels with different operating conditions.
NOTICE: The imager shield (see Figure 25 on page 25, item #415230, not shown in Figure 3) 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 recommends using a backscatter shield assembly (Item # 415600) with your OVDX.

Figure 4 Example Scatter Radiation Survey
Figure 4 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 4 was created with the following conditions:
 8" Steel Pipe
 2" Calcium Silicate Insulation
 .040” [1 mm] thick Aluminum Cladding
 70 kV @ 0.17 mA (maximum power)
See the following section for additional information on backscatter.

Backscatter
CAUTION
Whenever scanning an unknown material and/or geometry, it is recommended that operators monitor for
backscatter levels to minimize operator dose.
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
backscatter shield (Figure 5) will help reduce the amount of backscatter when firmly applied to the scanning surface as
shown in Figure 7.
