摘要： When an ultrasound endoscope arrives at an objective area, a puncture needle is located in a scan area of a first ultrasound image. Thereby, an image of the puncture needle is delineated on the first ultrasound image. Furthermore, an ultrasound probe is inserted into the puncture needle and an ultrasound transducer of the ultrasound probe is arranged in the objective area through the puncture needle. Then, the ultrasound probe is driven and a second ultrasound image is delineated. Detailed observation inside the objective area in which the puncture needle is punctured is possible with the second ultrasound image.
