Abstract: A catheter-type ultrasound endoscope according to an embodiment of the present invention includes an ultrasound module for acquiring an ultrasound image, and a biopsy needle, wherein the ultrasound module includes a pMUT module and an ASIC signal processing circuit, and the ASIC signal processing circuit uses CMOS-MEMS technology. This steerable catheter-type ultrasound endoscope capable of performing tissue biopsies according to the present invention obtains ultrasound images from representative digestive organs, such as the bile duct and the pancreatic duct, through the miniaturization of the ultrasound module, and performs a biopsy while the ultrasound images are observed in real time, and thus can improve the accuracy of diagnosis.

Abstract: Disclosed is a method for examining cells including: acquiring image data of cells acquired from a region suspected to be a cancer lesion; analyzing the image data; determining whether an amount of the cells is sufficient based on the analyzed result; and determining whether cancer-probable cells are included in the cells based on the analyzed result and the determined result; wherein the cells are acquired through Fine Needle Aspiration (FNA).
