1. An apparatus for detecting a bone fracture of a subject, the apparatus comprising:
a first fracture detector configured to receive a first ultrasound image of a region of the subject wherein the first ultrasound image includes a bone of the subject, to identify the bone in the first ultrasound image, to detect a hematoma adjacent to the identified bone by performing texture analysis in a sub-region of the first ultrasound image, to identify at least one focus area within the region in the first ultrasound image as a region covering the hematoma and a portion of the identified bone adjacent to the hematoma, to generate focus area information indicating a position of the at least one focus area, and to instruct an acquisition of a second ultrasound image of the region based on the generated focus area information; and
a second fracture detector configured to receive the second ultrasound image of the region, and to detect a bone fracture based on at least the second ultrasound image, wherein resolution of the second ultrasound image in the at least one focus area is higher than resolution of the second ultrasound image outside the at least one focus area within the region, and wherein the resolution of the second ultrasound image in the at least one focus area is higher than resolution of the first ultrasound image in the at least one focus area.
