Capsule guiding system
First Claim
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;
whereinthe 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.

Abstract
A capsule guiding system includes a magnetic guiding unit, a displaying unit, an operation unit, and a control unit. The magnetic guiding unit guides, using magnetic force, a capsule-shaped medical apparatus introduced inside a subject. The displaying unit displays an image of the subject and an image of the capsule-shaped medical apparatus as an overlapped image, and changes relative position and relative direction between the two images as the capsule-shaped medical apparatus is guided by the magnetic guiding unit. The operation unit inputs coordinate information which specifies movement direction of the capsule-shaped medical apparatus. The control unit adjusts coordinate system of the displaying unit and coordinate system of the operation unit to be consistent with each other, transforms the coordinate information input from 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 transformed coordinate information.
