A medical imaging apparatus (10) for evaluating medical image data is disclosed. The medical imaging apparatus comprises an ultrasound acquisition unit including an ultrasound probe (14) for acquiring ultrasound image data of a patient (12) and an ultrasound segmentation unit (24) for segmenting anatomical features of the patient in the ultrasound image data and for providing ultrasound segmentation data (46). The apparatus comprises an image data interface (18) for receiving 3D medical image data of the patient and a medical image segmentation unit (26) for segmenting the 3D medical image data and for providing medical image segmentation data (48). A user input interface (38) is provided for identifying a position (44) by the user in the 3D medical image data and/or in the ultrasound image data in order to initiate the segmentation of anatomical features by the medical image segmentation unit and/or the ultrasound segmentation unit on the basis of the position identified by the user, wherein a registration unit (32) correlates the ultrasound segmentation data and the medical image segmentation data.
