Abstract

A device is provided for ultrasound-based reflection and transmission tomography. A plurality of ultrasonic transducers are held around an imaging volume to be filled with an ultrasonic coupling medium, the transducer holder having an opening for inserting, into the imaging volume, at least one part of a body to be imaged. During imaging, the body to be imaged is supported, where a support-member-opening allows access to the transducer holder by at least one part of the body. A diaphragm is arranged across the support-member-opening such that a center of a diaphragm-opening is placed substantially at a predetermined position. The ultrasonic coupling medium flows out of the imaging volume when at least one part of the body to be imaged is inserted into the imaging volume filled with the ultrasonic coupling medium and/or during imaging.
