In this case, the operator had finished acquiring a hepatobiliary iminodiacetic acid (hida) scan on the brightview spect camera for a pt who (b)(6).The operator executed the "pt load" pre-programmed motion (ppm) to remove the pt from the system.While the imaging pallet was retracting onto the imaging couch, the imaging couch began to lower while the imaging pallet was partly on the lifter.The imaging pallet began to bind and the operator activated an emergency stop button to halt the system motion in a controlled fashion.The operator was able to remove the pt from the imaging pallet.A philips service engineer evaluated and found that the bushing screwed into the drive gear had failed from the drive block when the imaging pallet was retracting onto the imaging couch.There was no harm to the pt.
