The present invention proposes an apparatus and method for detecting bone fracture of a subject based on ultrasound images. The apparatus comprises a first fracture detector and a second fracture detector. The first fracture detector is configured to receive a first ultrasound image of a region of the subject, to identify a bone in the first ultrasound image, to identify at least one focus area within the region on basis of the identified bone (e.g. on basis of a detected hematoma), and to generate focus area information indicating position of the at least one focus area. The second fracture detector is configured to receive a second ultrasound image of the region acquired based on the generated focus area information, and to detect bone fracture on the basis of the second ultrasound image. The second ultrasound image has a higher resolution in the at least one focus area than in the rest of the region, and the resolution of the at least one focus area in the second ultrasound image is higher than the resolution of the at least one focus area in the first ultrasound image.
