Abstract: A cutting apparatus includes a management unit having a measuring unit for measuring an amount of light emitted from a light emitter and received by a light receiver while a cutting blade is positioned between the light emitter and the light receiver, a measured waveform forming section for forming a measured waveform representing the configuration of an outer circumferential region of the cutting blade, and an ideal waveform recognizing section for recognizing one of the comparative waveforms that has the greatest number of waveform regions similar to the measured waveform as an ideal waveform, a difference calculating section for calculating the area of a region where there is a difference between the measured waveform and the ideal waveform.

Abstract: Systems and methods are described, which generate a plurality of virtual monochromatic X-ray images having different energy levels even with a CT system with single energy CT. An example CT system includes an X-ray tube in which a prescribed tube voltage (120 (kVp)) is applied and one or more processors. The one or more processors perform an operation including inputting a CT image generated based on the single energy CT data collected from a subject body to a trained neural network (94), and causing the trained neural network to infer 40 (keV), 50 (keV), 60 (keV), 80 (keV), 90 (keV), and 100 (keV) virtual monochromatic X-ray images based on the CT image.
