LightSpeed 1.X with S-DAS4 Gantry and GRE
Symptom
Intermittent Scan Aborts at beginning of scan, Wrong angle Scouts (0 degree image looks more like 90 degree), All laser lights do not light. See LD for more details Intermittent Scan Aborts at beginning of scan, Wrong angle Scouts (0 degree image looks more like 90 degree), All laser lights do not light. 3 symptoms were seen 1 – Axial scans intermittently Abort at the beginning of the scan of the scan. 2 – Scouts scans intermittently Abort at the beginning of the scan. In addition sometimes if a 0 degree Scout is prescribed, when the picture is reconstructed it doesn’t look like it was taken at 0 degrees. It looks more like a Scout image taken at 90 degrees. 3- The laser lights intermittently do not all light. Specifically the external lights were mentioned as not being on. (or came on but because the gantry was not rotating to the correct location. The lights did not shine through the laser light cutouts in the gantry)
