An ultrasound tomography device for scanning an object under examination from a plurality of directions. Coronal slice images of the plane areas near or at the female breast wall are obtained. Ultrasound lobes from ultrasound transducers are electronically directed or mechanically positioned to obliquely strike the coronal slice located at or near the breast wall. A full image of the coronal slice plane is reconstructed through section by section combination of the images obtained from the several ultrasound lobes.

An ultrasound tomography device for scanning an object under examination from a plurality of directions. Coronal slice images of the plane or planes near or at the female breast wall are obtained. A sagittal scanner is used to obtain numerous small sectional oblique views of the slice to be viewed. A full image of the coronal slice plane is reconstructed through section by section combination of the images obtained from the several small sagittal sections. By providing the sagittal scanner with a scanning motion as well as with translational mobility a full composite view is provided.

The invention relates to a device and method for examining female mammals using at least one displaceable ultrasonic transducer which is disposed for scanning level layer areas and with which ultrasonic beams can be injected into at least one mammal via a coupling medium. The or each ultrasonic transducer can be displaced on a predetermined path length by means of a transporting unit so that three-dimensional ultrasound images which are electronically filed in a storage area can be generated by a computer-aided assignment of a data value, said value corresponding to the offset, to each layer image of an image sequence of layer levels of the or ski each mammal, said levels running parallel to one another. In order to reduce artifacts, differential images are calculated which are then subtracted from the original ultrasound image in a sign-specific manner. In addition, ultrasound images which are recorded by a variably tilted linear scanner are mapped on a common coordinate system or are projected in the direction of recording which is determined by the angle of tilt. Afterwards, said images are freed of artifacts min the same manner by means of a subtraction method.

A scanhead for use in ultrasonic echo cardiography is described. The scanhead is particularly adapted for imaging a patient's heart from the patient's esophogus. The scanhead is comprised of a rotating base having a phased array or linear array scanhead mounted thereon, and the scanhead is rotated in order to change the cross-sectional plane of the heart which is intercepted by the ultrasound.

An ultrasound scanning system including an array of ultrasound transducers and a transporter for moving the transducers over a human back. The movement of the ultrasound transducers define a plane and a position transducer produces a position signal representative of the position of the ultrasound transducers in the plane. There is a means for producing a range signal representative of the distance between the transducers and the objects imaged in the back. The range signals are digitized and stored in an array in a digital memory with the position of each stored range signal in the array corresponding to the position of the transducer from which the range signal was obtained in the plane at the time the range signal was received. The range information is printed on a page or displayed on a cathode ray tube with the position of the printed data on the page or the data displayed on the cathode ray tube corresponding to the position on the plane of the back from which the data was obtained.
