Abstract: A processing apparatus includes a processor. The processor acquires an image in which region marker information of a lesion is set with respect to an ultrasonic image of an ultrasonic endoscope with a biopsy needle, and calculates an angle of the biopsy needle for inserting the biopsy needle into the lesion based on a movable range of the biopsy needle and the region marker information.

Abstract: The medical system includes a basket treatment tool a processor. The processor determines, one or more of: a first determination, based on a transmissive image including the biliary duct, of whether a size of a gallstone allows the basket treatment tool to remove the gallstone from the papillary orifice, or a second determination, based on a resistance when the basket treatment tool is pulled, of whether the resistance allows the basket treatment tool to remove the gallstone from the papillary orifice; and controls the basket treatment tool to remove the gallstone from the papillary orifice when one or more of the first determination or the second determination determines that the gallstone is removable from the papillary orifice.

Abstract: An endoscope system includes a direct-view endoscope configured to capture images, a treatment tool configured to be inserted into the endoscope, and a controller comprising hardware, the controller being configured to control a drive device to drive the endoscope and the treatment tool, to control driving of the endoscope to locate the endoscope inserted into a lumen in the vicinity of a nipple, to control driving of the treatment tool to move the nipple using the treatment tool, to acquire a first captured image of the nipple from the endoscope, and to predict a shape of a biliary duct connected to the nipple in the first captured image based on biliary duct shape information comprising a standard image of the nipple that is associated with a standard shape of the biliary duct.

Abstract: An information processing system includes a processor including hardware. The processor acquires an endoscope image from an endoscope in which a papillary portion appears in the endoscope image, corrects the endoscope image based on correction information which is identified by an organ structure, and determines route information of a lumen based on the corrected endoscope image.
