Abstract
One or more techniques and/or apparatuses described herein provide a roller truck comprising non-rotating dampening material that is configured to dampen vibrations and mitigate the transference of vibrations from a rotating gantry to a support frame and vice-versa during rotation of the rotating gantry relative to the support frame. It will be appreciated that two different types of roller trucks, base roller trucks and z-axis roller trucks, are described herein, and the non-rotating dampening material may be inserted into one or both types of roller trucks. While the instant disclosure finds particular application in the context of computed tomography apparatus, the instant disclosure is not intended to be limited to such applications.
Claims25
An apparatus comprising:
- a support frame;
- a rotating gantry configured for rotation relative to the support frame;
- and
- a roller truck configured to at least partially support the rotating gantry and facilitate rotation of the rotating gantry relative to the support frame the roller truck comprising a non-rotating dampening material for dampening vibrations caused by the rotation of the rotating gantry.

A method for constructing a roller truck for supporting a rotating gantry and for allowing for rotation of the rotating gantry relative to a support frame, comprising:
- attaching one or more rollers to one or more roller axles;
- coupling the one or more roller axles to a plate;
- coupling an attachment member to the plate, the attachment member configured to operably couple the roller truck to at least one of the rotating gantry or the support frame;
- inserting a non-rotating dampening material into the roller truck, the non-rotating dampening material configured to dampen vibrations caused by the rotation of the rotating gantry relative to the support frame.

A computed tomography apparatus comprising:
- a support frame;
- a rotating gantry configured for rotation relative to the support frame, the rotating gantry comprising an x-ray source and a detector array;
- and
- a roller truck configured to support the rotating gantry and to allow the rotating gantry to rotate relative to the support frame, the roller truck comprising a non-rotating dampening material configured to dampen vibrations caused by the rotation of the rotating gantry relative to the support frame.
