超声治疗学——Chap.9 How image-guided ultrasound could treat a casualty with an injured spleen. (a) The injured patient is scanned using ultrasound imaging. (b) The anatomical cross-sectional of the injured spleen. The ultrasound-imaging probe (green) and high-intensity ultrasound device (blue) are coupled together to guide the focal point of the acoustic energy during treatment. (c) An ultrasound image of the spleen before treatment shows lacerations and bleeding. (d) After treatment the bleeding has stopped. The bright region on the diagnostic ultrasound image of the spleen indicates the treated region
