Scanning acoustic-photoacoustic microscopy using axicon transducers
A dual mode scanning acoustic microscope is investigated, yielding simultaneously images with optical and acoustical contrast. Short laser pulses are used to excite acoustic waves in a sample for the photoacoustic imaging mode. At the same time the pulses irradiate a conical target generating limited diffraction acoustic waves (X-waves) for large depth of field ultrasound imaging. For photoacou...
متن کاملAcoustic properties of dialysed kidney by scanning acoustic microscopy.
BACKGROUND A correlation between acquired renal cysts in the dialysed kidney and renal cancer has long been debated, but no changes in the physical properties of kidneys at the microscopic level have been reported. The purpose of the present study was to classify the physical properties of the kidneys of patients undergoing haemodialysis at several stages of pathology by use of the scanning aco...
متن کاملScanning Acoustic Microscopy Investigation of Engineered Flip-chip Delamination
The rapid uptake of flip-chip technology within the electronics industry, is placing the reliability of such assemblies under increasing scrutiny. A key feature of the assembly process is the application of underfill to reinforce the attachment of the die to the printed circuit board. This has been identified in numerous studies as one of the major ways in which the reliability of the devices c...
متن کاملScanning acoustic microscopy for mapping the microstructure of soft materials
Acoustics provides a powerful modality with which to ‘see’ the mechanical properties of a wide range of elastic materials. It is particularly adept at probing soft materials where excellent contrast and propagation distance can be achieved. We have constructed a scanning acoustic microscope capable of mapping the physical microstructure of such materials. We review the general principles of sca...
متن کاملUltrasonic tissue characterization of infarcted myocardium by scanning acoustic microscopy.
The purpose of this study was to ultrasonically characterize infarcted human myocardial tissue at the microscopic level by scanning acoustic microscopy. Infarcted myocardial specimens from ten cases with acute myocardial infarction were studied. Specimens were formalin fixed, paraffin embedded and sectioned to 10-micron thickness. A specially developed scanning acoustic microscope system, opera...
