Patent ID: 10918304

Abstract:
A rheology system (202) includes a rheology transducer device (204) for introducing mechanical waves into a subject of interest (120). The rheology transducer device (204) includes multiple transducers (212), a driving device (206) for driving the rheology transducer device (204), a sensor device (208) for sensing mechanical waves at the subject of interest (120), and a control device (210) for receiving input from the sensor device (208) and for controlling the driving device (206) based on the received input from the sensor device (208). An MR rheology system (200) includes the above rheology system (202) and an MR imaging system (110) adapted to control the rheology system (200). A rheology method includes with the rheology system (202), driving the rheology transducer device (204) to introduce mechanical waves into the subject of interest (120), sensing mechanical waves at the subject of interest (120), and performing feedback control.
