## Indications for use
The L7 when used with Aspen ultrasound system is capable of providing diagnostically useful images of anatomy and pathology in the major bone, joint, and muscle groups of the human body. Specific anatomy and pathology in the neck, shoulders, arms, elbows, wrist, hand, hips and pelvis, legs, knees, ankles and feet can be imaged. The images obtained depict anatomical structures and regions of increased and reduced blood flow which are useful to physicians in detecting normal and abnormal conditions in these regions of the body.
