- LightSpeed RT4 WB O G4 G HPT WB O M4 G HPT LightSpeed RT4 with GRE and MDAS4 or GDAS4 gantry At GE Medical Systems, we’re pioneering exciting CT technology for Radiation Therapy planning. Introducing the newest addition to our LightSpeed® series – LightSpeed RT, the first multi-slice, wide-bore CT scanner with the largest field of view in the industry. With a generous 80 cm gantry opening, the LightSpeed RT bore is 10 cm larger than conventional scanners. This provides complete flexibility for patient positioning freedom – even for the most demanding oncology needs. And the 65 cm variable field of view delivers 15 additional centimeters of visual coverage, allowing clinicians to see a patient’s entire anatomy for precise radiation therapy planning. Position and precision Thin, multi-slice imaging is the extra bonus – enabling respiratory gating, providing precise target delineation and delivering higher resolution digitally reconstructed radiographs (DRRs) than ever before. All adding up to the ability for you to deliver what really matters most – better cancer care for your patients. Plus, the LightSpeed RT scanner is available with the Exact™ couch insert, enabling you to consistently replicate patient immobilization for treatment. With LightSpeed RT, the future of your Radiation Oncology department is wide open.

- 2342727-4 : 5.X Cradle encoder. This part replaces the 2342727-3 and 2342727-2 This is an absolute position encoder with no pot. See long description for details Displaying Change-Up Data: Part "2342727-2" and "2342727-3" changed to 2342727-4 Part #: 2342727-4 Part Type: GP CONSUMABLES Part Weight: 0.00 LBR Repairable: No Returnable: No Hazardous Material: N Description: FRABA OCD H-Power String Encoder FRU: Yes Status: Orderable Comments: Added by ecr: 2020264. Please continue to use stock of 2342727-3, until depleted. -3 and -4 are mfg alts of one another. ms13452 Revised per to Asset confirmation Comments: Added per ECR2011883 to replaced the 2342727-2 The 5.x table design incorporates Absolute encoders used for cradle and elevation, instead of incremental encoders. The absolute encoder has the capability to generate a unique binary 'word' for each encoder shaft position, allowing the encoder to provide positional information instantly upon power-up, unlike incremental encoders. Therefore, potentiometers are NOT needed for cradle or elevation encoder circuits.
