Abstract

The title of the invention is systems and methods for table movement control. The invention discloses a magnetic resonance imaging (MRI) system (100). The MRI system includes a table (110) and at least one processor (120). The table (110) is configured to support the patient (102) and travel along the length (112) in a direction of movement (113) through the imaging zone (114) to at least one imaging location (115). The spatial gradient field varies for at least a portion of the imaging zone. At least one processor (120) is operably coupled to the stage (110) and is configured to: obtain a spatial gradient field curve representing a magnitude of a spatial gradient field as a function of a position along the direction of movement (113); determine a table velocity profile using the spatial gradient field profile, wherein the table velocity varies along the direction of movement; and control the movement of the console (110) using the console speed profile.

Description

Background technique [0001] The subject matter disclosed herein relates generally to apparatus and methods for providing table movement control, eg, controlling movement of a patient table in a medical imaging system, such as a magnetic resonance imaging (MRI) system. [0002] The speed of table motion for MRI protocols is limited to avoid exposing the patient to excessive rate changes in magnetic field strength. However, certain conventional methods for console speed can result in table speeds that are too slow, thereby increasing the amount of time it takes to transport the patient and lengthening the imaging procedure. Contents of the invention [0003] In an exemplary embodiment, a magnetic resonance imaging (MRI) system is provided that includes a table and at least one processor. The table is configured to support the patient and to travel lengthwise through the imaging zone in a direction of movement to at least one imaging location. The spatial gradient field varie...
