Three-dimensional periodontal investigations using a prototype handheld ultrasound scanner with spatial positioning reading sensor

Functional optoacoustic human angiography with handheld video rate three dimensional scanner☆

Optoacoustic imaging provides a unique combination of high optical contrast and excellent spatial resolution, making it ideal for simultaneous imaging of tissue anatomy as well as functional and molecular contrast in deep optically opaque tissues. We report on development of a portable clinical system for three-dimensional optoacoustic visualization of deep human tissues at video rate. Studies ...

Three-dimensional Accurate Positioning Algorithm based on Wireless Sensor Networks

Three-dimensional accurate positioning algorithm, using RSSI-based (Received Signal Strength Indication) positioning method, which constructs an attenuation model of wireless signal between beacon node and unknown node in three-dimensional space, and compensates for the loss of wireless signal on the basis of their material, thickness and other factors when there are obstacles or walls being in...

Interferometric-spatial-phase imaging for sub-nanometer three-dimensional positioning

Current alignment technology is incapable of satisfying the needs of imminent generations of lithography. This dissertation delineates a novel method of alignment and three-dimensional position metrology that is compatible with many forms of proximity lithography. The method is called Interferometric-Spatial-Phase Imaging (ISPI), and is based on encoding three-dimensional position information i...
