Abstract: A method for generating a map indicative of mechanical properties of subject tissue using an MRI system includes performing an MRE scan on the subject tissue with the MRI system and obtaining and processing MRE data related to the subject tissue via a control device. The control device is configured to perform a plurality of operations including: encoding a series of motions and obtaining MRE data samples in a plurality of directions at a predetermined number of time points, constructing a plurality of phase images based upon the obtained MRE data samples, and having a number of phase images in a range from 7 to 24, estimating shear displacement fields in the subject tissue based on the plurality of phase images, wherein estimation includes an optimization performed according to an EDGE matrix, and generating the map indicative of the subject tissue's mechanical properties via an inversion algorithm.

Abstract: An adjustable folding table apparatus for attachment to a seat back for use primarily within an automobile or other vehicle, including a tray portion rotatable between a substantially vertical stored position and a substantially horizontal extended position, suspended from a portion of the seat back and employing a series of flexible straps to enable both facilitated attachment and detachment of the apparatus from the seat back, as well as adjustment of the vertical and/or angular orientation of the tray apparatus. A latch or catch serves to retain the tray portion in a folded up or stored position until it is dislodged.
