GE Healthcare Revolution CT Systems: Incorrect Dose Display Risk
GE Healthcare recalls Revolution CT, Revolution CT ES, Revolution Apex, and Revolution CT with Apex edition CT scanners due to potential overdisplay of radiation dose during interventional exams with SmartStep.
The accumulated dose is incorrectly displayed in certain situations. Thisoccurs during an interventional exam using the SmartStep option if the table height is adjusted after the exam starts. In this situation, the SmartStep display will show a value that is higher (up to 100 times) than the actual dose delivered.
