In addition, there is a risk that the puncture needle is inserted into the puncture needle insertion hole at the wrong angle due to a mistake in reading the puncture needle insertion angle. There is also.

Further, since only one type of puncture guide can be displayed on a diagnostic image, when determining the insertion angle of the puncture needle that matches the lesion, the puncture guide at each angle must be switched and displayed by keyboard operation. In addition, there are problems that it takes time and effort, and that it is difficult to deal with the puncture needle insertion hole.
