Ultrasound Computed Tomography (USCT) is a radiation free imaging technique that provides acoustic properties information of the human tissue. It commonly provides three image modalities: reflection image, sound speed image and attenuation image. As a newly developed medical instrument, the imaging performance of the USCT should be tested following standard method and provided to the users for...

26. A sound speed phantom for hybrid photoacoustic-ultrasound transmission tomography

A composite test object comprising regions with different sounds speeds was developed to evaluate the ultrasound-transmission tomography component of the PAM3 system. The system is capable of hybrid photoacoustic-ultrasound transmission tomography. The test object is made of various materials such as olive oil, copolymer-in-oil and water, and has values of sound speed as expected in breast....

4. A Calibration Algorithm for a Large Circular Array of Ultrasound Transducers

oral presentations

We consider a planar circular array of a large number of ultrasound emitter-receiver elements. Due to unavoidable inaccuracies of the manufacturing process, the actual positions of the elements slightly differ from the ideal equidistant positions on the circle; also, there exist delays in emitting and receiving the signals. For every emitter-receiver pair available are the accurate enough...

First results of KIT 3D USCT III system crosstalk analysis

Motivation

The KIT 3D USCT III system is built around the idea of SAFT. One ultrasound transducer emits a signal while thousands of others receive - Leading to a system with large number of parallel channels consisting of cables, traces, and connectors. SAFT requires unfocused small transducers necessitating a multi-stage...

9. A serially scalable emission and acquisition system architecture for ultrasound computed tomography

Background:
Most emission and acquisition systems for research and applications in ultrasound computed tomography (USCT) are custom-built and lack scalability in the number of emitting and receiving channels. To address this problem, we proposed a serially scalable emission and acquisition system architecture that is available to build emission and acquisition systems with different...
