CLINITEK Atlas® Automated Urine Chemistry Analyzer Calibration Online Training

Magnetic Susceptibility increases linearly at 3T. Some of the challenges are increased in-plane spatial distortions and increased through-plane excitation errors. Magnetic susceptibility has a larger affect on GRE sequences due to the use of gradient refocusing pulses instead of RF refocusing pulses and higher sensitivity to T2 star effects.

If a 3D sequence is acquired with an isotropic voxel, the data may be reformatted using Multi-planar reconstruction. Multi-planar reconstruction is a post processing reformatting of a 3D data set into a different imaging plane than what the sequence was acquired in. In this example, it is showing a 3D Axial DESS  knee that has been loaded into the 3D MPR card and reformatted into the Sagittal plane. Congratulations.

Select Next to continue.  Note: If audio does not automatically start, select the play arrow in the top left to begin.Remove the calibration kit from the refrigerator and allow the calibrators to reach room temperature. Store the kit at 2 - 8 degrees Celsius when not in use. Check the thermal integrity card inside the box of calibrators to ensure the calibrators have not been exposed to excessive heat.2 Prepare Bleach Solution Pour at least 2 mL of 5.25% sodium hypochlorite into a sample tube. If the concentration of sodium hypochlorite is higher than 5.25%, dilute the bleach with distilled water. For example, if the bleach is 6% sodium hypochlorite, add 0.75 mL of water to 5 mL of the 6% bleach and gently swirl to mix. Select Next to continue. Pour at least 2 mL of 5.25% sodium hypochlorite into a sample tube. If the concentration of sodium hypochlorite is higher than 5.25%, dilute the bleach with distilled water. For example, if the bleach is 6% sodium hypochlorite, add 0.75 mL of water to 5 mL of the 6% bleach and swirl to mix gently.3 Prepare Sample Tubes Gently mix the calibrator bottles Pour at least 3 mL of calibration solutions 1, 2, and 3 into sample tubes labeled CAL 1, 2, 3. Pour at least 5 mL of calibration solution 4 into a sample tube labeled CAL 4. Allow the calibrators to come to room temperature before placing on the system.   Select Next to continue. Gently mix the calibrator bottles. Pour at least 3 mL of the calibration solutions 1,2 and 3 into sample tubes marked 1, 2, 3. Pour at least 5 mL of calibration solution 4 into a sample tube labeled 4. Allow the calibrators to come to room temperature before placing on the system.4 Load Tubes   Place the sample tubes in the rack in the following order: Bleach - pos. 1 Cal 4 - pos. 2 Cal 1 - pos. 3 Cal 2 - pos. 4 Cal 3 - pos. 5   Place this rack onto the right side of the Sample Handler, with the open side facing towards the back When complete, select the X in the upper-right corner to close the window and continue. Place the sample tubes into the rack in the following order: Bleach in position 1, then Cal 4, Cal 1, Cal 2, and Cal 3, as depicted on the screen of the Calibration Procedure A calibration can be initiated by: Selecting the Calibrate softkey  Responding to the instrument prompt when a new lot of reagent roll is loaded Steps during calibration: The SG Well is cleaned with the 5.25% bleach A dry calibration is performed which checks reagents and records baseline readings A clarity calibration is performed using calibrator 4 in the SG Well If clarity passes, calibrators 1-3 are aspirated in duplicate Performing a Calibration Learn about performing a calibration.

Intensiteten af ​​det reflekterede lys er afhængig af graden af ​​farveændring i testfeltet og er direkte relateret til koncentrationen af den komponent der testes for. Derefter ledes lyset gennem en åbning på linsen ogfokuseres på detektoren. Den detekterede lysintensitet omdannes til elektriske impulser, som omregnes til kliniske resultater af instrumentes mikroprocessor. You have just learned about performing a calibration.

Tab TitleTextLow Calibrator Volume If there is insufficient Calibrator volume this message will appear on the screen.  The calibration will have to be restarted after additional calibrator is added to the tube or tubes. Prime Pump When a new reagent roll is loaded, rinse solution will need to be prepared.  Carefully remove the canula when transferring it to avoid introducing an air bubble. If there are bubbles in the rinse solution line, this error may occur.  Select  Prime Pump on the error screen. Alternately, access the Main Menu and press 5. Prime Pump Pad Dispense Error When this error occurs it could indicate a problem with the pipette or reagents. Verify pipette performance by completing the Checking for Leakage maintenance procedure.  If the pipette is not performing correctly, it may need to be replaced.  Refer to the CLINITEK Atlas analyzer operating guide for more information. If the pipette is performing properly, another step to resolve this issue is to replace the reagent roll. Dry Calibration Failure This message is generated when the results from the dry calibration of a dry reagent strip are out of range. It can be related to the reagent pack quality, the readhead or the lamp.   Recalibrate the system.  If the problem persists, replace the reagent roll with a fresh, sealed roll pak and attempt calibration again.   Refer to the CLINITEK Atlas analyzer operating manual to clean the readhead or replace the lamp as needed.   Wet Calibration Failure This message can appear if: The calibrators were not at room temperature when analyzed on the system The calibrator tubes were loaded into the wrong rack positions The incorrect calibrator was poured into the labeled tube The calibrators have expired The reagent roll has expired There is an issue with the pipette To resolve a Wet Calibration Failure: Confirm the calibrators are at room temperature. Check the expiration date of the reagent roll and calibrators. Verify the tubes are in the correct positions and poured into the proper tubes. Verify pipette performance by completing the Checking for Leakage maintenance procedure.  If the pipette is not performing correctly, it may need to be replaced. Check the readhead and clean if necessary.     When complete, select the X in the upper-right corner to close the window and continue.
