Select Next to continue.   As we introduced in the overview, the Control Area of the Viewing Task Card is where you can find the Viewing  Tool Cards.  The Tool Cards house a wide assortment of image display and evaluation icons, like measurement tools and data management functions, all easily accessible and neatly grouped under tabbed headers. The properties of many of the tools can be configured to your specific needs as well - just right click on a button to view and modify it's properties. Let's take a look at the features that are available in the Tool Cards. You will need to perform a calibration update: Every 30-90 days for any one lot, depending on the method calibration stability claim When you start using a new test method on your instrument When you start using a new TestPak lot When QC monitoring indicates After a major part is replaced If QC performance indicates Calibration Theory Learn more about the theory of calibration. When the TestPaks are manufactured, calibration coefficients (C terms) are assigned to each lot.   The analyzer reads these coefficients from the TestPak barcode and stores them in the system memory.   The system calculates the mean of three replicates and mathematically transforms one of the coefficients, the C1 term, into a new updated C1 term.  The system uses the new C1 term and other coefficients from the TestPak barcode to calculate test results when the new lot of TestPaks is used on the Stratus® CS.  The C1 update must be within specific %CVs to pass.  Refer to the TestPak insert for further details. This calibration update procedure fine tunes the calibration allowing new TestPak lots and CalPak lots to work at their optimal performance.    When complete, select the X in the upper-right corner to close the window and continue. When to Perform Calibration Learn about when to perform a calibration. Tab TitleTextExpired Calibrations Calibration is routinely required every 30-90 days depending on the method calibration stability claim.  Refer to the TestPak Instructions for Use (IFU) for calibration stability and calibration interval information.   The Stratus® CS will not process a TestPak of an expired lot.   The message "Check Calibration Status" will appear on the System Check report when you are within 72 hours of a TestPak expiration or if the TestPak has expired.   Adding a new method If you are adding a new Test method to your assay menu, it is necessary to calibrate the test method prior to using.   The TestPak insert sheet provides you with the calibration stability and calibration interval.  Method stability is from 30 - 90 days depending on the test method. Adding a newTestPak Lot The Stratus® CS stores up to three different TestPak lots of any method.  This allows you to calibrate a new lot as soon as you receive it rather than waiting until the previously calibrated lot is expired.  The analyzer will not process TestPaks of an uncalibrated lot.     QC Monitoring When the message "Check Calibration Status" appears on the System Check Report, it is indicating that you should check the TestPak lot's status before processing a sample to determine if you need to process QC or a calibration.   You can review the information on the Reagent Status screen to determine which process you need to perform. Major Part Replacement In the event that service is performed and a major part is replaced on the system, it is necessary to perform calibrations.  The performance of the system may be altered depending on the part replaced.  Calibrating the methods will reset the calibration update allowing the system to perform optimally. QC Failure If QC fails on a particular TestPak lot it may be necessary to calibrate the method.  Steps to run a calibration are provided later in this course. When complete, select the X in the upper-right corner to close the window and continue. On the Patient Tab you will find additional shortcuts to common syngo functions, and  their availability and location may differ on your system.  On the Acquisition Workplace, the first row of icons on the Patient Tab provides quick access to Registering a patient, closing an open patient folder or opening the Scheduler.  The second row offers a filming preview shortcut and the ability to push selected data  to the Filming Task Card.  The last row offers a shortcut to the Patient Browser and a button to push selected data to the 3D Task Card. Calibration TestPaks are stored in the refrigerator with the exception of the CTNI and pBNP.  These two calibrator TestPaks are stored in the freezer.  They must be removed from the freezer 30 minutes prior to usage to allow them to come to room temperature.  Gentle mixing is necessary.  The other CalPaks are stored in the refrigerator and do not require coming to room temperature prior to use.  As with all the TestPaks, CalPaks or DilPaks, do not open until just prior to usage.   Performing a Calibration Learn about performing calibrations.

This web-based training provides ultrasound technologists and physicians with relevant information to enhance and improve their clinical knowledge of Virtual Touch IQ, also referred to as VTIQ on the ACUSON S2000 HELX Evolution and the ACUSON S3000 HELX Evolution ultrasound systems. This module explains  the technology and the clinical background and identifies what is required to successfully utilize and optimize VTIQ on the ACUSON S2000 HELX and the ACUSON S3000 HELX ultrasound systems A Calibrated TestPak Lot is deleted if: It is no longer being used It has expired You need to make room for an additional lot Note: The instrument holds up to three lots.

That is, sound is used to compress and interrogate tissue.   As you can see in the image, there are 3 Virtual Touch applications which utilize AFRI technology, and one, eSie Touch Elasticity Imaging, which uses compression-based technology.   Virtual Touch  Imaging (VTi)- provides a qualitative view of tissue stiffness   Virtual Touch Quantification (VTq) - provides a quantitative assessment, or measurement   Virtual Touch IQ (VTIQ)– combines imaging and quantification in one image. It  provides a visual and quantitative assessment   A calibration report is printed each time calibration is run. To determine whether the calibration was successful, view the print out. If the calibration is successful the printout displays, "Pass".  If it is not successful, the printout displays, "Fail". Evaluating a Calibration Learn about evaluating a calibration. Tab TitleTextCalibration Passed After calibration, ensure that the calibration status in the center of the report slip reads "Calibration Pass."  Confirm the calibration by running two levels of QC for the test method before using the TestPak lot for processing samples.    Calibration Failed At times the Calibration will fail due to situations such as: An incorrect alignment of the probe A poorly stored TestPak or CalPak You cannot use a TestPak lot until it has a successful (Pass) Calibration.  Follow the procedure on the next tab if your calibration status is "Fail." Calibration Troubleshooting Follow this procedure if the calibration status is "Fail."  Check the error message on the calibration status line. CV or Slope Error:  continue with step 2. Result Error:  check the error log for an error occurring about the same time as Run Time on the calibration report.   To troubleshoot the error, refer to the Troubleshooting section of the Stratus® CS Operator's Guide. Align system components, refer to your Stratus® CS Operator's Guide. Run System Check-refer to your Stratus® CS Operator's Guide. Rerun the calibration using a new CalPak and three new TestPaks from the same lot. If the calibration continues to fail, contact Siemens Technical Support Center.      When complete, select the X in the upper-right corner to close the window and continue.
