Patent number: 9427202Abstract: An arithmetic processor for measuring bone density using a correspondence relationship between a luminance value of transmitted radiation and a thickness of a reference material is provided. The luminance value is obtained by applying radiation, which is emitted from a radiation source upon application of a tube voltage to the radiation source, to the reference material having different thicknesses and detecting the radiation transmitted through the reference material. The arithmetic processor includes: a generating unit that generates, based on the detected luminance value, a luminance profile representing the correspondence relationship; a normalizing unit that generates a normalized profile by normalizing the luminance profile based on a maximum value and a minimum value in the luminance profile; and a determining unit that determines whether or not each luminance value corresponding to each thickness in the normalized profile is within a range defined in advance by the tube voltage and each thickness.Type: GrantFiled: July 3, 2014Date of Patent: August 30, 2016Assignee: FUJIFILM CorporationInventors: Kenji Yoshikawa, Takuma Okuno, Tsuyoshi Kamada
