Title INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
Abstract Provided is an information processing device, comprising a computation unit which, as an optimal solution which minimizes the difference between an observed displacement which has been acquired from an image in which a portion of an elastic body has been captured and an estimated displacement of a partial region corresponding to an observation region from among estimated displacements computed for a three-dimensional model of the elastic body, derives a size of an external force which acts upon a known point of application and a distribution of elasticity in the three-dimensional model.
Outline of related art and contending technology BACKGROUND ART
Cancer lesions seen in palpation, the information related to the hardness of the biological tissue, which are useful for a physician to render a diagnosis.In recent years, such as the living tissue of the organ quantitatively and objectively evaluate the information, the distribution of the image display are practical elastography.Elastography techniques include, for example nuclear magnetic resonance measuring method (Magnetic Resonance Elastography: MRE) and when ultrasonic elastography.
MRE is, magnetic resonance imaging (Magnetic Resonanse Imaging: MRI) and the elastic modulus measurement method used, the target object is captured in a state in which vibrations from the outside, the vibration wave propagating in the subject is a method of imaging.Is ultrasonic elastography, which is generated when the external pressure may be applied to a target object tissue strain distribution within the target tissue or a method using the shear wave is generated, the propagation speed of the technique represented by the method of use.
