Safety

WARNING!

FAILURE TO FOLLOW THE OPERATING INSTRUCTIONS AND SAFETY PRECAUTIONS COULD RESULT IN INJURY TO THE PATIENT, YOURSELF, OR OTHERS.

General Safetyo Keep the patient in view at all times. Never leave the patient unattended.

Always stay alert to safety concerns involving the patient's condition and equipment operation.

o Check the lengths of all patient health lines (IV tubing, oxygen lines, etc.) and make sure they accommodate cradle travel. Position these lines so they cannot catch on anything within the patient vicinity or between the table and gantry during cradle travel or gantry tilt.

o Always follow the exam procedures provided in the operator manual. Verify correct entry of identification, patient positioning, and other patient data before proceeding with the exam. Incorrect procedures or patient data entry could cause misinterpretation of the exam results.

o Conduct Image Quality checks and follow the maintenance schedule outlined in your CT/e operator manual. Discontinue use of the equipment whenever you notice equipment damage, or a malfunction occurs. Do not use the equipment until qualified service personnel correct the problem. Never use the equipment unless all the protective covers are in place.

Radiation Safetyo Use of controls or adjustments, or performance of procedures other than

those specified herein may result in hazardous radiation exposure.

o Always use proper technique factors for each procedure to minimize X-Ray exposure while still producing the best diagnostic results.

o Be sure to have an operator wear X-ray protection vest when a work is needed near the gantry while X-ray is being emitted.

!ixCT/e Operator Manual

Mechanical Safetyo Never open, or remove, the gantry covers. (Only qualified service personnel

should remove covers.)

o Do not enter the scan room when the gantry covers have been opened or removed. Never allow a patient or staff member to enter the scan room when the gantry covers have been removed for maintenance or PM. (Never allow anyone but qualified service personnel to enter the scan room during gantry maintenance or PM.)

o To prevent the pinching or crushing of extremities, keep hands and feet away from the edge of the moving table top/cradle and its surrounding equipment. (Be especially careful when positioning patients who weigh more than 250 pounds.)

o Physically assist all patients on and off the table, and into position on the cradle.

o While a patient is being loaded onto a CT table from a gurney, make sure via the following measures that the gurney NEVER moves.

Lock all the casters of the gurney. Hold the gurney very firmly.If the gurney moves while loading a patient, it may create a gap between the table and the gurney posing the danger of the patient falling through the gap.

o Return the gantry to the 0 upright position, latch the table, and set it at a comfortable height for patient loading and unloading.

o Avoid any patient contact with the CT gantry during gantry tilt and cradle movement (manual or software driven). Once again, pay close attention to large patients; make sure you don't pinch skin or extremities between the cradle and the gantry.

o The concentrated weight of short, heavy patients can cause the cradle to make contact with the gantry. Make sure you don't drive the cradle into the gantry cover, and make sure you don't pinch skin or extremities between the cradle and the gantry.

o Check the lengths of all patient health lines (IV tubing, oxygen lines, etc.) and make sure they accommodate cradle travel. Position these lines so they cannot catch on anything within the patient vicinity or between the table and gantry during cradle travel or gantry tilt.

o Do not use the table base as a foot rest. You could entrap and injure your foot while lowering the table.

o Don't place your hands inside the gantry cover when tilting the gantry. The gantry can pinch or crush your hands!

o Only use the cradle extender to support the patient's head or feet during a scan study. The cradle extender supports up to 75 pounds; the head holder x CT/e Operator Manual

supports up to 30 pounds. Neither device supports the full weight of a patient. If you sit, stand or otherwise apply excessive pressure to these devices, they will break or come off the cradle, and may cause injury.

o Periodically check all accessories for damage and remove from service if damaged or cracked. Also check the accessory attachment plate fixed to the end of the cradle. Repair or replace if loose or damaged.

o The cradle has a maximum distributed load capacity of 180 kg. GE assures incremental accuracy and normal traverse speeds up to 180kg. Exceeding the 180 kg maximum limit could result in degraded positioning performance, increased table lowering speed, equipment damage and/or injury.xiCT/e Operator Manual

Electrical Safetyo Avoid all contact with any electrical conductors. o Wait at least 10 minutes after the last scan before you turn off [Main Power].

This gives the circulating oil sufficient time to cool the X-Ray tube.

Software Safetyo Should a malfunction occur, or a patient condition develop that requires

interrupting a scan series, push (Abort) on the right end of the OC scan panel to stop X-Ray.

o Wait for image annotation to complete before filming. If you press the exposure button too soon, the film records a composite of two different scans.

o DICOM protocol has a "dialect", which may cause some troubles like disappearances of some portion of image annotations, when connecting to the station where data transfer is not confirmed.

Emergency Stopo In the event of a hardware failure that could cause serious damage, such as

smoke, fire or unintentional cradle movement, press one of the red [Emergency Stop] switches located on the operator console, at the gantry control panels, or on the X-ray Generator. Low power to the electronic components in the computer and data acquisition system remains ON.

o When Emergency Stop is applied, the moving cradle and tilting gantry may overrun by less than 10 mm and less than 0.5 degrees, respectively.

GE provides training support. Contact your local GE sales repre-sentative to arrange training sessions to meet your needs.xii CT/e Operator Manual

Note : Your system also has a warning label on a console that warns of the above hazard. xiiiCT/e Operator Manual

IMPORTANT SAFETY INFORMATIONAs a manufacturer of CT systems, we would like to take a moment to remind all Technologists and Radiologists that clinical interpretation errors can be made due to motion artifacts in large vessels, i.e. Thoracic Aorta. These motion artifacts may emulate a vessel dissection. Interpretation errors may cause misdiagnosis or unnecessary surgery. Vessel motion artifacts have been documented in Radiology literature for some time.

Motion artifacts in large vessels may be caused when using any manufacturers CT scanner capable of scanning with 1 second or less rotation times. The pulsation of the vessel creates a double margin of the vessel emulating a dissection. The motion artifact is an interaction between the pulsation of the vessel and the rotation time of the scan.

As an aide, we have updated the CT system with the following information to help rule out artifact or real pathology in clinical situations where a vessel dissection may be apparent.

It has been documented in radiology literature that an artifact may occur in the chest that bears the double margin of the great vessels, which emulates a dissection of the vessel during 0.5 to 1.0 second scans. This can occur in axial or helical scans. If you have scanned axially or helically with a 0.5 to 1.0 second rotation time and observe this phenomenon, rescan the area with a 2 second axial scan to verify if it is artifact or patient pathology.

Please ensure that the appropriate personnel in your CT Department are made aware of this notice. If you have any questions regarding this notice, please contact your local GE representative.

If you would like to review additional information in the clinical literature please review the following publication: Gotway, Michael: Helical CT evaluation of the thoracic aorta. Applied Radiology: Sept. 2000, 7-28. xiv CT/e Operator Manual

Overview of CT System and Examination

OverviewThe CT/e computed tomography (CT) system consists of four major components and some peripheral gear. Four major components are the gantry, table, operator console(OC) and power distribution unit (PDU). The primary objective of this CT system is to obtain for medical diagnoses the two or three-dimensional images of internal structure of human body.

General Procedures of CT Examination :

1. The operator prescribes the examination(scan) procedures at the OC while the patient is positioned on the table in the scan room.

2. As the operator initiates the scan procedures with the patient in the gantry aperture, the X-ray unit inside the gantry rotates around the patient body emitting the fan-shaped X-ray beam to the body. The X-ray penetrates the body and is received by the detector, then it is converted to the electrical data.

3. The data acquired in the above step is processed into the images by the computer at the OC. Then, the images are initially displayed on the Monitor of the OC and subject to manipulation for analysis. The images can also be filmed later for diagnoses by a physician.

4. The image data can be saved in some electronic media like optical disk for later analysis and also be transferred to some other stations for remote diagnoses.

HIPAA

The Health Insurance Portability and Accountability Act of 1996 (HIPAA) was signed by President Clinton on July 21, 1996 and has the general objectives to:

Guarantee health insurance coverage of employees.

Reduce health care fraud and abuse.

Introduce/implement administrative simplifications in order to augment effectiveness and efficiency of the health care system in the United States.

Protect the health information of individuals against access without consent or authorization. Within HIPAA there are Administrative Simplification regulations that, in early 2001, are in work.

GE Medical Systems has a longstanding reputation of providing customizable, clinical solutions to protect the privacy and security of your organization's unique clinical workflow, as well as your patient's confidentiality. Our scanner, software and services already incorporate many of the core HIPAA requirements. We are committed to working with you, our customer, to provide additional value to help you meet the continuing HIPAA challenge.

Please recognize the intended use of the product when determining how critical any privacy risk is, relative to patient care and safety. GE is very concerned with providing the best care to the patients; and in some cases we have determined that patient care is more important than the risk to privacy. In these cases we take every precaution to minimize the privacy risk.

Security and Privacy are maintained across a Healthcare system. Any product that is placed into an uncontrolled environment will not be secure and can not protect privacy. As we design scanners we design them to be implemented in a "Secure Environment". A secure environment is based on multiple layers of security, a concept known as defense in depth. For example: a Best Practice that is gaining much attention places firewalls between departments, as well as at a DMZ, between all extranets, and the external Internet access point. In this example a radiology firewall may allow DICOM and HL7 traffic through, but no other protocols. These DICOM and HL7 protocols would be blocked at the DMZ and again at the Internet Firewall.

HIPAA requires you to log on to the scanner and log off when you are done scanning for a period of time. If you do not log off the system will log you off and you will have to log back on.

HIPAA can be set up for groups of users. You can be an Empowered, Admin, Operator or Service user. Empowered users can modify protocols and do service functions. Admin users can set up user and delete users. Operator users can perform all scanning functions. Service users can do everything.

Note : HIPAA is an option that can be turned on or off by your Field Engineer.1-25CT/e Operator Manual
