3 D spin fails to complete its test spin

3 D spin fails to complete its test spin 3-d test does not complete its test spin. check the movements of the gantry per this instruction After the spin test completes, you have to stay on the test button until it goes all the way back to the start position at Patient right side to settle the gantry to start the high speed spin. Another possibility could be that you may be getting some counts from another position of the gantry or the table, everything has to stay absolutely still during the spin. Check that your L belt isn't loose and the table isn't moving, things like that. Could put scope on encoder and pot test points for each axis that should be stationary to see if it is getting any encoder pulses or changes in pot voltage. Another possibiliy is any gantry positioon not reaching the anticipated positon in software. Example the SID is set at 120CM, if it varies more than a half a CM from this there will be an errro created in the Spin3DCalib.log on the AWW. etc. Checking the positoner CPU trace is another good toubleshooting tip. Here is an Example of a VME-344GE trace: Result of “mini-reset” that occurs during a 3D spin test…Result of “mini-reset” that occurs during a 3D spin test… Push and hold the “test” button on the TSSC... Gantry moves to: L-arm = 3 degrees C-arc (Caudal) = 6 degrees Pivot (LAO) = 99 degrees II SID = 125 cm TV camera = 3 degree rotation Positioner CPU board “resets” All encoder history is cleared out with this “reset”.
