A vibration absorber damper and method of dissipating vibration energy in a rotatable structure which is nominally cyclic symmetric. The nominally cyclic symmetric structure includes a hub portion having a rotational axis and a plurality of radial members radially extending from the hub portion. The hub portions having a groove extending circumferentially about the rotational axis. The vibrational absorber having a ring member having a plurality of repetitive cellular structures each defining a hollow interior section and a plurality of deformable members each extending from the ring member and disposed in a corresponding one of the repetitive cellular structures. Each of the deformable members is configured to interact with the cyclic symmetric structure to damp vibration thereof.

An ultrasound imaging system uses a magnetic linear motor driven ultrasound scanner, with accurate track and hold operation and/or other motion feedback, to scan a two dimensional or three dimensional area of a sample. The scanner is implemented in a low-power and low-bandwidth handheld device and is connected with a remote image processing system that receives raw data and performs full ultrasound image analysis and creation, allowing the handheld to be used for scanning, pre-processing, and display.
