Safety Information
To the User of This Manual
The user of this manual is directed to read and carefully review the instructions, warnings and cautions contained herein prior to beginning installation or service activities.
While you may have previously installed or serviced equipment similar to that described in this manual, changes in design, manufacture or procedure may have occurred
which significantly affect the present installation or service.

Installation and Environment

Except for installations requiring certification by the manufacturer per federal standards, see that a radiation protection survey is made by a qualified expert in accordance
with NCRP 102, section 7, as revised or replaced in the future. Perform a survey after every change in equipment, workload, or operating conditions which might
significantly increase the probability of persons receiving more than the maximum permissible dose equivalent.

Diagnostic Imaging Systems - Mechanical-electrical Warning

All of the moveable assemblies and parts of this equipment should be operated with care and routinely inspected in accordance with the manufacturer’s recommendations
contained in the equipment manuals.
Only properly trained and qualified personnel should be permitted access to any internal parts. Live electrical terminals are deadly; be sure line disconnects are opened and
other appropriate precautions are taken before opening access doors, removing enclosure panels, or attaching accessories.
Do not under any circumstances, remove the flexible high tension cables from the x-ray tube housing or high tension generator and/or the access covers from the generator
until the main and auxiliary power supplies have been disconnected. Failure to comply with the above may result in serious or fatal bodily injuries to the operator or those
in the area.

Electrical-grounding Instructions
The equipment must be grounded to an earth ground by a separate conductor. The neutral side of the line is not to be considered the earth ground. On equipment
provided with a line cord, the equipment must be connected to properly grounded, three-pin receptacle. Do not use a three-to-two pin adapter.

Diagnostic Imaging Systems - Radiation Warning

X-ray and Gamma-rays are dangerous to both operator and others in the vicinity unless established safe exposure procedures are strictly observed.
The useful and scattered beams can produce serious or fatal bodily injuries to any persons in the surrounding area if used by an unskilled operator. Adequate precautions
must always be taken to avoid exposure to the useful beam, as well as to leakage radiation from within the source housing or to scattered radiation resulting from the
passage of radiation through matter.
Those authorized to operate, participate in or supervise the operation of the equipment must be thoroughly familiar and comply completely with the current established
safe exposure factors and procedures described in publications, such as: Subchapter J of Title 21 of the Code of Federal Regulations, "Diagnostic X-ray Systems and Their
Major Components", and the national council on radiation protection (NCRP) no. 102, "Medical X-ray And Gamma-ray Protection For Energies Up To 10 Mev-
equipment Design and Use", as revised or replaced in the future.
Those responsible for planning of x-ray and gamma-ray equipment installations must be thoroughly familiar and comply completely with NCRP no. 49, "Structural
Shielding Design and Evaluation For Medical Of X-rays and Gamma-rays of Energies Up to 10 Mev", as revised and replaced in the future. Failure to observe these
warnings may cause serious or fatal bodily injuries to the operator or those in the area.
Add additional safety information as needed

Access Dual Performance Manual

Introduction
This document provides system performance tests, test methods, and performance specifications for the Access Dual
System. Personnel using this document and performing these tests are expected to be familiar with CT system test
methods and the operation of the Access Dual System. A Access Dual System meeting these performance
specifications is a necessary but not sufficient condition for acceptable system performance and acceptable image
quality for system shipment to customers and subsequent clinical use.

Scope
This document applies to all completely assembled and fully calibrated Access Dual CT Systems.

Overview
The purpose of the Performance, Constancy, Acceptance and QA tests are as follows:
• Performance Test
Run this test after major component replacement such as, X-ray tube or DAS. This tests the general image quality
of the scanner.
• Acceptance Test
The Acceptance test is run in the field for the newly installed scanner or if major changes were made in the scanner
version and/or scanner hardware. The result obtained during the Acceptance test is the base line for the next
Constancy test.
• Constancy Test
The Constancy test is run during Planned Maintenance or component replacement. Constancy measures the
performance and stability of the system relative to the results received in the Acceptance test.
• QA Test
The QA test runs scans to compare the CT number Uniformity, and Noise of the scan with the allowed tolerance.

Safety

!
WARNING Collision Hazard! When mounting the phantom make sure that it is positioned
so that it will not come in contact with the gantry covers or the rotor.

!
CAUTION Collision hazard! Before carry out performance testing, lift the vertical moveable couch to
340cm to avoid collision with the Gantry.

!
CAUTION Collision hazard! When mounting the system phantom make sure that it is positioned so
that it will not come in contact with the gantry covers or the Rotor.

!
WARNING Close all Gantry covers before performing tests. Check that the temperature
regulation of the gantry and the DMS function properly. Wait for the
temperature to stabilize within ±2 ℃ .

!
CAUTION Ensure that the phantom is completely vertical (Tilt = 0) before performing any calibration
or performance tests; tilt or misalignment of the phantom may result in inaccurate
calibration and performance tests.

Prerequisites for Performance Testing

1. All operating software has been installed and Auto-Calibration has been successfully completed.
2. The system is fully functional with all hardware and software calibrations complete and performs according to
specification. All covers must be in place and securely attached. All other safety covers or switches must be in their
normal operating positions or states unless specifically changed by a test procedure.
3. The X-ray tube must be warmed up to a nominal tube heat (20%) before starting the test and all air calibrations
must be current.
4. The Gantry / Detector cooling system must be fully functional, and must maintain normal and stable temperatures.
The normal DMS(Data Measurement System) operating temperature is 32 ±2°C. It is important to maintain
temperature stability within ±2°C between calibration and image performance testing in order for the test results to
be valid.

Automatic Performance Test

The Automatic Performance Test runs scans of different types to check the performance of the system, the full test
performs 16 scans in different modes and takes approximately 15 minuntes to complete.

Before Beginning the Automatic Performance Test

• The Automatic Performance tests scans the images automatically but does not check the individual scans for rings,
bands and artifacts; inspection of images MUST be performed by the FSE. No rings or bands are allowed on the
image. Use a window width of 100 for Head and 150 for Body, with the window centered on the CT number of the
material (e.g. 0 for Water).
• For all Scans: If a scan in any mode fails with comply to specified tolerances, repeat the scan manually using the
same parameters and verify that the results are correct. The SD and CT tolerance values may change during the
lifetime of the system.
NOTE If the error message” Tube Power Limit Exceeded” is displayed, wait until the tube cools down and try
running the scan again.

Appendix A: System Test Phantom

The test phantom used for the majority of these tests is the System Performance Phantom. This phantom is supplied as
part of every Access Dual system. The phantom consists of a combined Head and Body Phantom. The Head Phantom
is a 200 mm diameter PVC shell filled with distilled water. The Head Phantom has three sections (see detailed
description of the system phantom in Figure 14 on page 18–Figure 17 on page 21.
1. The physics layer is used for impulse response and tomographic section thickness (slice width) measurements.
2. The water layer is used to measure uniformity and noise.
3. The Multi–Pin Layer is used for low contrast scale check.
4. The body layer is used to measure CT values for body agreements and noise.
The Body Phantom part of this phantom consists of a water hole (0 ±10 CT) and air (1000 ±10 CT).
