Scanning tomographic acoustic microscopy

IEEE Transactions on Image Processing, 1995
The scanning tomographic acoustic microscope (STAM) was proposed in 1982 as a method of improving the resolution capability of the scanning laser acoustic microscope (SLAM) based on the principles of tomography. By modifying the SLAM with a quadrature detector, tomographic projections that contain both the amplitude and phase information of the ...

Scanning acoustic tunneling microscopy and spectroscopy: A probing tool for acoustic surface oscillations

Journal of Vacuum Science & Technology an Official Journal of the American Vacuum Society B, Microelectronics Processing and Phenomena, 1997
A method is presented for the universal probing of surface acoustic waves (SAWs). For measuring high frequency SAWs by scanning tunneling microscopy (STM) a stroboscopic snapshot technique was employed, named scanning acoustic tunneling microscopy.

Scanning Tomographic Acoustic Microscopy

SPIE Proceedings, 1988
The technology for "seeing" with sound has an important and interesting history. Some of nature's creatures have been using sound waves for many millenia to image otherwise unobservable objects. The human species, lacking this natural ability, have overcome this deficiency by developing several different ultrasonic imaging techniques.

Scanning Acoustic Microscopy

1994
Scanning acoustic microscopy is a form of microscopy based on the generation and detection of elastic waves in solids. The basic mechanism is the interaction of an acoustic wave with a specimen and the consequent generation of acoustic waves inside the material.

Scanning acoustic microscopy

Physics Today, 1979
The resolving power of the scanning acoustic microscope now rivals that of the optical microscope. Since Calvin Quate and Ross Lemons reported building the first scanning acoustic microscope in 1974, Quate's group at Stanford has been able to improve the resolution of this instrument every year by about a factor of two; they now report they have ...

Recent advances in scanning tomographic acoustic microscopy

International Journal of Imaging Systems and Technology, 1991
AbstractWe present the recent developments of the Scanning Tomographic Acoustic Microscope (STAM). The STAM was proposed as a method to achieve 3D imaging capability for the Scanning Laser Acoustic Microscope (SLAM). With the addition of a quadrature receiver, the complex scattered wave field can now be detected, and consequently the STAM is capable of

An Iterative Algorithm for Scanning Tomographic Acoustic Microscopy

Ultrasonic Imaging, 1991
Acoustic microscopy is capable of providing high-resolution images of small objects. When such a microscope operates in the transmission mode, it produces simply a shadowgraph of all the structures encountered by the acoustic wave passing through the object.

Scanning tomographic acoustic microscopy

The Journal of the Acoustical Society of America, 2002
This paper provides an overview of the design and development of the scanning tomographic acoustic microscopy (STAM). This research effort spans over a period of more than 12 years, which successfully elevated the acoustic microscopy from the traditional intensity-mapping mode to the level of holographic and tomographic imaging. The tomographic imaging

CHARACTERIZATION OF RENAL ANGIOMYOLIPOMA BY SCANNING ACOUSTIC MICROSCOPY

The Journal of Pathology, 1997
A scanning acoustic microscope system was used to differentiate renal angiomyolipoma from renal cell carcinoma. The ultrasonic frequency used ranged from 100 to 200 MHz, and the attenuation constant and sound speed were measured on a two-dimensional distribution.

Study of Cellular Adhesion with Scanning Acoustic Microscopy

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2007
A mechanical scanning acoustic reflection microscope was applied to living cells (e.g., osteoblasts) to observe their undisguised shapes and to evaluate their adhesive conditions at a substrate interface. A conditioned medium was collected from a bone-metastatic breast cancer cell line, MDA-MB-231, and cultured with an immature osteoblast cell line ...
