An acoustic driver system includes an active acoustic driver and a passive acoustic driver. The active acoustic driver is configured to produce oscillating acoustic energy. The passive acoustic driver is acoustically connected to the active acoustic driver and is configured to receive the oscillating acoustic energy and to convert it into shear waves. The passive acoustic driver includes a housing member and a vibrating member. The housing member includes a housing member cavity. The vibrating member is disposed at least partially within the housing member cavity. The vibrating member permanently retains a curved shape while disposed within the housing member cavity.

A cartwheel tumbling doll has a torso and a head mounted on the torso. An axis extends generally through the center of the head and torso. A pair of arms, each arm having a shoulder end and a hand end, are mounted for limited pivotal movement adjacent each arm's shoulder about a respective axis that is generally perpendicular to the center axis. A pair of legs, each leg having a hip end and a foot end, are mounted adjacent each leg's hip for limited pivotal movement relative to the torso about a respective axis that is generally perpendicular to the center axis. A weight is releasably connected to each hand. The foot of each leg contacts a substantially planar surface to support the doll in a generally upright position with the arms extended away from the feet and carrying the releasably connected weights. Pushing one side of the doll causes it to tumble sideways or cartwheel. When each weight contacts the surface, a release mechanism releases each weight from its respective hand permitting the doll to continue to cartwheel until the feet again contact the surface and the doll is in the generally upright position.

An adjustable cycle-type seat post assembly comprises a tubular seat post which fits slidably within an upstanding tubular seat mast. The seat post has a cylindrical bore with a closed upper end and an open lower end. A mounting shaft has an elongated body comprising upper and lower head portions with an intermediate portion between them. The upper head portion has a piston with O-ring seals engaging the cylindrical bore and defining with the closed upper end a variable volume air chamber. The intermediate portion has an axially extending slot engaging a pin secured to the seat post to limit relative axial movement and prevent relative torsional movement. The mounting shaft is secured in the seat mast by axially spaced openings in the lower head, one of which is engaged with a water bottle connecting stud extending through the seat mast wall. Ribs flanking the openings align them with the water bottle stud to facilitate assembly. A bicycle pump valve at the upper end of the seat post enables pressurization of the air chamber.

In one aspect of the disclosure, an MRI-based system includes an MRI scanner having a first axis and a first plane perpendicular to the first axis, a pulse sequence module configured to provide a 3D pulse sequence to the MRI scanner, and a control module configured to instruct the MRI scanner to conduct radial k-space samples having N second planes that each are perpendicular to the first plane and through which the first axis passes, N being an integer greater than 1. The 3D pulse sequence instructs the MRI scanner to a radio-frequency (RF) pulse, conduct a gradient readout in the first plane, and conduct a gradient readout in one of the N second planes.

A method for calculating quantitative perfusion measurements using an MRI system includes a pulse sequence that acquires perfusion weighted images and additionally measures Tvalues before and after the administration of a contrast agent. Tvalues are measured by rapidly sampling a longitudinal relaxation curve and employed to determine the blood volume in tissue. A correction factor for the effect of water diffusion between blood vessels and the extravascular space is determined.

A magnetic resonance angiogram (MRA) is acquired using a contrast enhancement method in which a series of NMR images are rapidly acquired during a time resolved phase of the examination in which the contrast bolus makes a first pass through the arteries and veins. Arterial and venous voxels are automatically identified in the images using either of two disclosed methods. The signals from identified arterial voxels are used to produce an arterial contrast enhancement reference curve that is used to segment arterial voxels by a correlation process. Venous voxels are segmented in the same manner using a calculated venous contrast enhancement reference curve.

A system for perfusion and diffusion MR imaging of a portion of patient anatomy includes an RF (Radio Frequency) signal generator for generating RF excitation pulses in anatomy and enabling subsequent acquisition of associated RF echo data. A magnetic field gradient generator generates anatomical volume select magnetic field gradients for phase encoding and readout RF data acquisition in a three dimensional (3D) anatomical volume. The RF signal generator and the gradient generator acquire within a single MR imaging scan, perfusion image data of the 3D volume, at least partially in the presence of contrast agent, and diffusion image data of the 3D volume.
