Abstract: A diagnostic system, method, and a computer-readable storage medium for determining a severity of a gastric condition, such as gastritis, in a subject are disclosed. The diagnostic system includes a processor that obtains an image of a stomach of the subject collected by an endoscope. The processor can compare the subject image with reference normal and abnormal stomach images. If the subject image is abnormal, the processor can generate a subject abnormality image indicative of the differences between the subject image and the normal image. By comparing the generated subject abnormality image with reference abnormality images representative of different severity levels of gastritis, the processor can diagnose the subject as having a particular severity level of gastritis.

Abstract: A diagnostic system, method, and a computer-readable storage medium for determining a severity of a gastric condition, such as gastric cancer, in a subject are disclosed. The diagnostic system includes a processor that can obtain various images of a stomach of the subject including wavelength images and generate difference images from the wavelength images. The processor can compare the subject images with reference images representative of different severity levels of gastric cancer, or can input the subject images into a learned model trained using the reference images stored in the database to extract a feature pattern corresponding to a severity of gastric cancer to diagnose the subject as having a particular severity level of gastric cancer.

Abstract: An apparatus includes a rotation body, a motor, a drive controller, a rotating speed detector, a rotation error determination circuit, and a filter. The rotation body is provided on an outer peripheral surface of an elongated insertion section and configured to be rotatable around a longitudinal axis. The motor rotates the rotation body. The drive controller controls driving of the motor. The rotating speed detector detects a rotating speed of the motor based on an encoder signal output from an encoder. The rotation error determination circuit determines an error in rotation of the rotation body based on the detected rotating speed. The filter passes, as the encoder signal, only a signal having a frequency, outside a frequency band of a high-frequency signal of a high-frequency treatment instrument, of signals input to the rotating speed detector.

Abstract: A controller which controls an operation of a self-propelled mechanism of an endoscope includes an inspection control section, a usual control section, an endoscope connection detection circuit and a control switch section. The endoscope connection detection circuit detects that the endoscope has been connected. The control switch section determines whether or not the inspection operation is performed for the endoscope at the time of the connection of the endoscope, causes the usual control section to perform the usual operation when the inspection operation is performed, and causes the inspection control section to perform the inspection operation and then causes the usual control section to perform the usual operation when the inspection operation is not performed.
