Manufacturer Reason
for Recall		Software defect: For Helical scan with ClearView function, when small arc (uninterrupted scan) occurs during scan, there will be some electromagnetic interference in the system which may affect the control signal of the flying focal spot, resulting in an incorrect flying focal spot sequence. If the system does not receive error, it would continue to complete the scan with the incorrect flying focal spot sequence, having an effect on the reconstruction of some images, resulting in image loss.
