Photoacoustic breast scanner
TL;DR: In this paper, the authors described mathematical reconstruction procedures for producing images from transducer signals, and specific arrangements of transducers were illustrated, where the transducers are moved to collect data from multiple locations, to facilitate imaging.
Journal ArticleDOI
Hall effect imaging
TL;DR: A new imaging method based on the classical Hall effect (HE), which describes the origin of a detectable voltage from a conductive object moving in a magnetic field, which may be a useful tool for biological research and medical diagnosis.
Journal ArticleDOI
Industrial applications of piezoelectric polymer transducers
TL;DR: The discovery of highly active piezoelectric polymer materials was first reported in 1969 and an enormous amount of research work has been conducted, mainly aimed at discovering the structure and properties of these fascinating materials with the further aim of improving their pyroelectric behaviour.
Patent
Thermoacoustic computed tomography scanner
TL;DR: In this article, a rotatable imaging bowl with multiple acoustic transducers arranged on an orthogonal axis is used to measure acoustic waves produced in the tissue when the tissue is exposed to a pulse of electromagnetic radiation.

Pulsed Photoacoustic Techniques and Glucose Determination in Human Blood and Tissue
TL;DR: This thesis focuses on pulsed photoacoustic techniques, which have potential ability in non-invasive blood glucose determination, which are invasive and liable to afflict a degree of pain and cause skin injury.

Early and recent intraluminal ultrasound devices
TL;DR: This chapter surveys methods for catheter tip echo imaging, subdividing them into a) measurements; b) Doppler and c) imaging, concluding with the results of automatic contour analysis of the inner arterial boundaries.
Early and recent intraluminal ultrasound devices
TL;DR: The history of intraluminal echography dates back to the very beginning of diagnostic ultrasound and many fascinating ideas and applications of catheter tip or gastroscopic tube tip mounted transducers have been described as discussed by the authors.
