摘要：
An ultrasound diagnostic device comprises an ultrasound endoscope, an ultrasound diagnostic signal processing device and a monitor and is arranged to obtain an ultrasound diagnostic image by performing transmission/reception of ultrasound signals with respect to a detection subject within a body cavity. The ultrasound endoscope comprises an insertion section inserted into a body cavity, an operating section and a connecting cord. A biopsy needle insertion/retraction section is employed for forward or backward insertion/retraction of a biopsy needle. The subject may be pierced by the needle tip of a biopsy needle that protrudes from a biopsy needle protrusion port at the tip of an insertion section of the ultrasound endoscope which has been inserted. The monitor displays the biopsy needle in the ultrasound diagnostic image. The ultrasound diagnostic signal processing device is constituted as superimposition means that superimposes a boundary of the advance of the piercing direction of the biopsy needle on the display of the ultrasound diagnostic image by the monitor.
