摘要：
The invention relates to a contact determination apparatus for determining a degree of contact between a device (2) and a moving object (3), wherein the contact determination apparatus comprises a motion distribution providing unit for providing a motion distribution being indicative of motion in the surrounding of the device and a contact determination unit (14) for determining a degree of contact between the device and the object based on the provided motion distribution. Since the degree of contact between the device and the object is determined based on the provided motion distribution and not simply based on, for instance, a peak of an A-mode signal, the determination of the degree of contact can be less disturbed by artifacts like ring-down artifacts or by blood scattering, if the object is, for instance, tissue. This can lead to a more accurate determination of the degree of contact.
