Product Synergy XVI

XVI can incorrectly calculate the target position of the treatment table, because of an error that does not occur very frequently. This is the sequence of events when this error occurs - (1) You do an online VolumeView acquisition and registration. (2) You accept the registration and the Table Move Assistant dialog box appears. (3) The Relative Actual column of the Table Move Assistant dialog box incorrectly appears blank. (4) When this occurs, XVI does not read the Absolute Actual position of the treatment table. This causes XVI to calculate the treatment table moves from the zero position of the treatment table (+0.0, + 0.0, + 0.0). (5) In XVI R5.0, if the Relative Set values are less than or equal to + or -2.5cm (for earlier releases of XVI, the value is + or -2cm), you can do remote automatic table movement (RATM) from the function keypad (FKP). (6) When you press the Table ASU (automatic setup) buttons, the treatment table moves to a position that was incorrectly calculated from XVI.

Action Elekta sent an Important Field Safety Notice dated November 2013, to all affected customers. The letter identified the product the problem and the action needed to be taken by the customers. Potential collision risk when using XVI and external beam shaping devices released November 25, 2013 (Only software versions R4.5, R4.5.1, R4.6 and R5.0 are applicable to this recall). (All software versions R4.6 in this notices are applicable to this recall). Recommendations to Users - Monitor the Actual column of the Table Move Assistant dialog box. If the Actual is blank, do not press the ASU button the FKP. To correct the error - (1) Restart XVI. (2) Put the patient in their initial setup position. (3) Scan the patient again, and continue the usual workflow. Always monitor the patient when you do RATM. When you do Volume View acquisitions with the Apex collimator attached, make sure that the stop angle of the Volume View parameters is in the lower half of the gantry rotation. This decreases the risk of a collision with the patient. Read and follow the advice int he Important Field Safety Notices and acknowledge receipt to your Elekta representative within 30 days. Corrective Action #2 - Permanent Solution - XVI Risk control measure - changes to the software to prevent table movement if the start position has not been recorded correctly. Recommendations for changes to product are - (1) Table zero should default to NIHII not zero. (2) Check that the table zero is valid because calculating absolute table positions. (3) Check prescribed table position is not more than 2.5cm from actual table position when permitting ASU from outside room. Users of software version 4.5, 4.5.1 and 4.6 will receive a mandatory upgrade to XVI 5.0. The estimated release date for the fix for the XVI 5.0 is December 2014. For further questions call ( 770 ) 300-9725.
