In an ultrasonic CT device for breast examination, unevenness of an ultrasonic image due to a distribution of inclination angles of a breast is reduced. The distribution of the inclination angles of a surface of a subject in a contour of the subject is obtained from a tomographic image, and a signal level of a reception signal or a pixel value of the tomographic image is corrected using the distribution of the inclination angles.

The invention relates to a molded gel body (1), the production thereof and the use thereof in ultrasonography in the medical or dental field. In particular, the molded gel body (1) is used to detect and localize dental cavities in the jawbone by means of through-transmission alveolar ultrasonography (TAU). The molded gel body (1) has a receptacle (2) for receiving an ultrasound transmitter and/or receiver (7). The molded gel body (1) and the receptacle (2) are preferably adapted to the shape of the ultrasound transmitter and/or receiver. For easier handling, the molded gel body (1) is inserted into a flexible, biocompatible protective cover (6) which, like the receptacle (2), can be filled with a non-dimensionally stable ultrasound gel. To produce the molded gel body (1), cuboids of a dimensionally stable gel of the appropriate size are preferably cut open over the narrow lateral surfaces of the cuboid, but preferably not completely cut through and only over three of the four sides to produce the receptacle (2) or, if not completely cut open, closed or glued on the edges only over two of the four sides.

The present invention relates to determining the rotation of an interventional device in an ultrasound field. An interventional device is provided that is suitable for being tracked in an ultrasound beam of a beamforming ultrasound imaging system by correlating transmitted ultrasound signals from the beamforming ultrasound imaging system as detected by ultrasound receivers attached to the interventional device with the beamforming beam sequence of the ultrasound signals. The interventional device includes a longitudinal axis (A-A′), a first linear sensor array (12) comprising a plurality of ultrasound receivers (R.sub.1 . . . n) wherein each ultrasound receiver has a length (L) and a width (W), and wherein the array extends along the width (W) direction. Moreover the first linear sensor array (12) is wrapped circumferentially around the interventional device with respect to the axis (A-A′) such that the length (L) of each ultrasound receiver is arranged lengthwise with respect to the axis (A-A′).

A method for a noninvasive determination and/or monitoring of the intracranial compliance of a biological material includes performing an acoustic spectroscopy of a human or an animal skull; comparing the acoustic transmitting signals with the corresponding acoustic receiving signals, and determining a function in n-dimensions, which is characteristic for the biological material; determining the expansion of the biological material, the linear expansion and/or volume expansion of the biological material being measured, and determining the intracranial compliance of the biological material based on the comparisons.
