Underlying the conception and design of this new imaging system were severai design considerations specifically directed toward its application in clinical cardiology. These include image rates commensurate with cardiac dynamics, a field of view sufficiently large to allow image formation of most or all of the left ventricle, and the utilization of a relatively small, hand-held transducer which...

PURPOSE Optoacoustic imaging relies on the detection of ultrasonic waves induced by laser pulse excitations to map optical absorption in biological tissue. A tomographic geometry employing a conventional ultrasound linear detector array for volumetric optoacoustic imaging is reported. The geometry is based on a translate-rotate scanning motion of the detector array, and capitalizes on the geome...

Hybrid optical modality imaging is a special type of multimodality imaging significantly used in the recent past in order to harness the strengths of different imaging methods as well as to furnish complementary information beyond that provided by any individual method. We present a hybrid-modality imaging system based on a commercial clinical ultrasound imaging (USI) system using a linear arra...

SUMMARY Passive seismic methods in highly populated urban areas have gained much attention from the geophysics and civil engineering communities. Linear arrays are usually deployed for passive surface wave investigations because of their high convenience, imaging commonly used linear can be grouped as non-interferometric (e.g. multichannel analysis wave, refraction microtremor) interferometric ...

Objective—To develop a high resolution, near field optimized 14 MHz 24-element broad bandwidth forward-looking array for integration on a steerable 9 French (Fr) electrophysiology (EP) catheter. Methods—Several generations of prototype imaging catheters with bi-directional steering, termed the Micro-Linear (ML), have been built and tested as an integrated catheter design with EP sensing electro...
