1. A system for making a measurement of a hip in an ultrasound image, the system comprising:
a memory comprising instruction data representing a set of instructions; and
a processor configured to communicate with the memory and to execute the set of instructions, wherein the set of instructions, when executed by the processor, cause the processor to:
obtain an ultrasound image of a hip including an ilium and a femur head;
obtain a spatial coherence map associated with one or more lags of ultrasound waves associated with the ultrasound image;
determine a quality metric based on the ultrasound image of the hip and the spatial coherence map, wherein the quality metric indicates a suitability of the ultrasound image for making the measurement of the hip; and
if the quality metric indicates that the ultrasound image is above a threshold quality, indicate that the ultrasound image is suitable for making the measurement of the hip.
