## Abstract

The invention relates to a device (1) for positioning a marker (2) in a 3D ultrasonic image volume (3), a system for positioning a marker (2) in a 3D ultrasonic image volume (3), a method for positioning a marker (2) in a 3D ultrasonic image volume (3), a computer program element for controlling such device (1) for performing such method and a computer readable medium having stored such computer program element. The device (1) comprises an image provision unit (11), a marker unit (12) and a display unit (13). The image provision unit (11) is configured to provide a 3D ultrasonic image volume (3) showing an object (4). The marker unit (12) is configured to position a marker (2) in the 3D ultrasonic image volume (3). The display unit (13) is configured to display the 3D ultrasonic image volume (3) and the marker (2) in a first imaging view (31) in a first imaging plane and in a second imaging view (32) in a second, different imaging plane. The positioning of the marker (2) is limited to be on a projection line (5). The first and the second imaging views are rotated relative to each other, so that the projection line (5) has a first angle relative to the first imaging plane and a second, different angle relative to the second imaging plane.

## Claims

### Claim 1

A device for positioning a marker in a 3D ultrasonic image volume, comprising:
a processor: and
a display unit,
wherein the processor is configured to provide a 3D ultrasonic image volume showing an object,
wherein the processor is configured to position a marker in the 3D ultrasonic image volume,
wherein the display unit is configured to display the 3D ultrasonic image volume and the marker in a first 3D imaging view in a first imaging plane and in a second 3D imaging view in a second, different imaging plane,
wherein the positioning of the marker is limited to be on a projection line,
wherein the first and the second 3D imaging views are rotated relative to each other, so that the projection line has a first angle relative to the first imaging plane and a second, different angle relative to the second imaging plane, and
wherein the processor is configured to crop a volume of the second 3D imaging view to cut out an element covering the projection line.

### Claim 2 (depends on 1)

The device according to claim 1, wherein the processor is configured to position the marker in the second 3D imaging view in the volume of the object.

### Claim 3 (depends on 1)

The device according to claim 1, wherein the processor is configured to position the marker in the first 3D imaging view in a first position on a surface of the object and to reposition the marker in the second 3D imaging view in a second position in the volume of the object.

### Claim 4 (depends on 1)

The device according to claim 1, wherein the processor is further configured to crop the volume by means of a plane crossing the projection line.

### Claim 5 (depends on 1)

A system for positioning a marker in a 3D ultrasonic image volume, comprising:
a device according to claim 1, and
an ultrasonic probe,
wherein the ultrasonic probe supplies data to an image provision unit of the device.

### Claim 6

A method for positioning a marker in a 3D ultrasonic image volume comprising the following steps:
a) providing a 3D ultrasonic image volume showing an object,
b) positioning a marker in the 3D ultrasonic image volume, wherein the positioning of the marker is limited to be on a projection line, and
c) displaying the 3D ultrasonic image volume and the marker in a first 3D imaging view in a first imaging plane and in a second 3D imaging view in a second, different imaging plane, wherein the first and the second 3D imaging views are rotated relative to each other, so that the projection line has a first angle relative to the first imaging plane and a second, different angle relative to the second imaging plane, and
d) cropping of a volume of the second 3D imaging view to cut out an element covering the projection line.
