Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A medical image processing apparatus, comprising:
 an image information generating unit configured to generate image information for acquiring a superposed image having a three-dimensional image of a medical device over a three-dimensional image of a structure; and   an output unit configured to output the image information,   wherein the image information generating unit corrects the structure in the superposed image on a basis of a state of contact, detected by a detector of the medical device, of the structure and the medical device, and   wherein the output unit outputs the corrected image information.   
     
     
         2 . The medical image processing apparatus according to  claim 1 ,
 wherein, in a case where the contact of the structure and the medical device is detected by the detector, the image information generating unit corrects the structure in the superposed image in a manner that the structure approaches the medical device.   
     
     
         3 . The medical image processing apparatus according to  claim 2 ,
 wherein the image information generating unit performs correction in a manner as to enlarge the structure in the superposed image.   
     
     
         4 . The medical image processing apparatus according to  claim 3 ,
 wherein the image information generating unit performs the correction in a manner that, of the structure, a portion corrected to be enlarged and other portion are displayed continuously.   
     
     
         5 . The medical image processing apparatus according to  claim 1 ,
 wherein, in a case where non-contact of the structure and the medical device is detected by the detector, the image information generating unit performs correction to reduce visibility of the structure in the superposed image.   
     
     
         6 . The medical image processing apparatus according to  claim 5 ,
 wherein the image information generating unit reduces the visibility of the structure in the superposed image either by reducing size of the structure or by deleting the structure.   
     
     
         7 . The medical image processing apparatus according to  claim 1 ,
 wherein the detector is a pressure sensor; and   wherein the state of contact is acquired on a basis of change-of-pressure information detected by the pressure sensor.   
     
     
         8 . The medical image processing apparatus according to  claim 1 ,
 wherein the medical device includes a curvature deformation unit.   
     
     
         9 . The medical image processing apparatus according to  claim 8 ,
 wherein the curvature deformation unit has a serially aligned structure of node rings in an axial direction of the node rings.   
     
     
         10 . The medical image processing apparatus according to  claim 8 ,
 wherein the detector is provided on the curvature deformation unit.   
     
     
         11 . The medical image processing apparatus according to  claim 8 ,
 wherein the detector is an attitude sensor configured to detect attitude of the curvature deformation unit.   
     
     
         12 . The medical image processing apparatus according to  claim 8 , further comprising:
 a control unit configured to control deformation of the curvature deformation unit.   
     
     
         13 . The medical image processing apparatus according to  claim 12 ,
 wherein the control unit communicates with the medical device wirelessly.   
     
     
         14 . The medical image processing apparatus according to  claim 1 ,
 wherein the three-dimensional image of the structure includes a marker; and   wherein the image information generating unit generates the image information by using the marker.   
     
     
         15 . The medical image processing apparatus according to  claim 1 ,
 wherein a viewpoint of the superposed image is changeable.   
     
     
         16 . The medical image processing apparatus according to  claim 1 , further comprising:
 a display unit configured to display the corrected image information.   
     
     
         17 . An image information generation method of generating image information for acquiring a superposed image having a three-dimensional image of a medical device over a three-dimensional image of a structure, comprising:
 correcting the structure in the superposed image on a basis of a state of contact, detected by a detector of the medical device, of the structure and the medical device, and   outputting the corrected image information.   
     
     
         18 . The image information generation method according to  claim 17 ,
 wherein, in the correction, in a case where the contact of the structure and the medical device is detected by the detector, the structure in the superposed image is corrected in a manner that the structure approaches the medical device.   
     
     
         19 . The image information generation method according to  claim 18 ,
 wherein the correction is performed in a manner as to enlarge the structure in the superposed image.   
     
     
         20 . The image information generation method according to  claim 19 ,
 wherein the correction is performed in a manner that, of the structure, a portion corrected to be enlarged and other portion are displayed continuously.   
     
     
         21 . The image information generation method according to  claim 17 ,
 wherein, in a case where non-contact of the structure and the medical device is detected by the detector, the correction is performed to reduce visibility of the structure in the superposed image.
