Abstract:
1. A capsule guiding system comprising: a magnetic guiding unit which guides a capsule-shaped medical apparatus adapted to be introduced inside a subject by magnetic force; a displaying unit which displays a subject image showing the subject and a capsule image showing the capsule-shaped medical apparatus as an overlapped image, and changes a relative position or a relative direction of the subject image and the capsule image according to a guiding of the capsule-shaped medical apparatus performed by the magnetic guiding unit; an operation unit which inputs coordinate information specifying a movement direction of the capsule-shaped medical apparatus, and operates the guiding of the capsule-shaped medical apparatus performed by the magnetic guiding unit; a control unit which adjusts a coordinate system of a display screen of the displaying unit and a coordinate system of an input operation direction of the operation unit to be consistent with each other, performs a coordinate transformation which transforms the coordinate information input by the operation unit into the coordinate system of the magnetic guiding unit, and controls the guiding of the capsule-shaped medical apparatus based on the coordinate information on which the coordinate transformation is performed; a body position detecting unit which detects a body direction of the subject; and a direction detecting unit which detects the relative direction of the displaying unit to the magnetic guiding unit; wherein the control unit determines a correspondence relation between the input operation direction of the operation unit and the movement direction of the capsule-shaped medical apparatus based on a relative direction of the displaying unit to the magnetic guiding unit; the control unit changes the correspondence relation between the input operation direction of the operation unit and the movement direction of the capsule-shaped medical apparatus according to change of the relative direction of the displaying unit detected by the direction detecting unit; and the control unit keeps the body direction of the subject viewed from the displaying unit consistent with a body direction of the subject on the display screen, and keeps a horizontal input operation direction of the operation unit consistent with a horizontal direction of the display screen.
