The shielding tray reduces the radiation exposure to those organs, such as lungs, which are desired to be shielded. ## Device Story PC-controlled radiation therapy patient support assembly; facilitates whole body radiation therapy. Device features motorized patient table, shielding tray, and attenuating tray. Clinician places patient on table; custom lead shields positioned over organs (e.g., lungs) to reduce radiation exposure. Motorized system moves table and shielding tray coincidentally during treatment. Includes Plexiglas housing for bolusing materials and slots for dose verification. Safety features include limit switches, automatic treatment termination if table fails to move, and interlocks for attenuation stand. Used in hospital settings by clinicians. Benefits include controlled patient motion during therapy and automated, synchronized shielding to protect sensitive organs. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Materials: steel/aluminum rails, Plexiglas housing. Energy: low voltage motor system. Control: PC-based motor control. Features: motorized longitudinal table movement, motorized shielding tray, attenuating tray with safety interlock, digital movement indicators. Connectivity: standalone. Sterilization: not specified. ## Regulatory Identification A powered radiation therapy patient support assembly is an electrically powered adjustable couch intended to support a patient during radiation therapy. ## Predicate Devices - Siemens - ZXT Treatment Table ([K910971](/device/K910971.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

This method reduces the potential of radiation exposure to the sensitive organs, e.g., lungs, which are intended to be protected. - Attenuating stand has a safety interlock to assure that it is in place before beam is activated. 4. - The Plexiglas housing on the table permits the patient have bolusing material place around them in a more ನೆ convenient fashion. There are no other differences which would have a significant effect of the safety or effectiveness of the device. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
