Medical image processing system and a method for processing a medical image
View Patent ↗The medical image processing device comprises a detection part, a storage part, an image generation part, and a display-control part. The detection part detects positions and directions of an endoscope. The storage part stores medical image data showing tubular tissues generated by a medical imaging device different from the endoscope. The image generation part generates virtual endoscopic image data showing the internal portion of the tubular tissues based on the medical image data having a position that is a predetermined distance away from the position of the endoscope as a viewpoint. The display-control part receives endoscopic image data showing the internal portion of the tubular tissues generated by the endoscope and displays an endoscopic image based on the endoscopic image data and a virtual endoscopic image based on the virtual endoscopic image data on a display part.
1. A medical image processing device comprising:
a detection part that detects a position and a direction of an endoscope;
a storage part that stores medical image data showing tubular tissues generated by a medical imaging device different from said endoscope;
an image generation part that receives information indicating a traveling direction in which said endoscope is traveling within said tubular tissues and a speed of the endoscope and automatically generates, based on the received information indicating the traveling direction and speed, virtual endoscopic image data showing an internal portion of said tubular tissues based on said medical image data with a viewpoint, said viewpoint being one of the position of the endoscope and a position that is a predetermined distance away from the position of said endoscope in the traveling direction; and
a display-control part that receives endoscopic image data showing the internal portion of said tubular tissues generated by said endoscope and that displays an endoscopic image based on said endoscopic image data and displays a virtual endoscopic image generated from the virtual endoscopic image data generated by the image generation part on a display.
2. The medical image processing device according to claim 1 , wherein said image generation part generates said virtual endoscopic image data with the direction of said endoscope as a view direction.
3. The medical image processing device according to claim 1 , further comprising:
an identification part that identifies a tumor candidate based on said medical image data; and
a determination part that receives a sequence of observations regarding said tumor candidate to determine said traveling direction of said endoscope based on said sequence.
4. The medical image processing device according to claim 3 , further comprising a measurement part that obtains a distance from the position of said endoscope to said tumor candidate, wherein:
said display-control part displays said distance on said display.
5. The medical image processing device according to claim 3 , wherein:
said display-control part generates a marker indicating said tumor candidate, superimposes said marker on a position of said tumor candidate in the virtual endoscopic image and displays the virtual endoscopic image on said display.
6. A method for processing a medical image, comprising:
detecting a position and a direction of an endoscope;
storing medical image data showing tubular tissues generated by a medical imaging device different from said endoscope;
an image generation step of receiving information indicating a traveling direction in which said endoscope is traveling within said tubular tissues and a speed of the endoscope and automatically generating, based on the received information indicating the traveling direction and speed, virtual endoscopic image data showing an internal portion of said tubular tissues based on said medical image data having a viewpoint, said viewpoint being one of the position of the endoscope and a position that is a predetermined distance away from the position of said endoscope in the traveling direction; and
a display-control step of receiving endoscopic image data showing the internal portion of said tubular tissues generated by said endoscope and for displaying an endoscopic image based on said endoscopic image data, and displaying a virtual endoscopic image generated from the virtual endoscopic image data, on a display.
7. The method for processing a medical image according to claim 6 , wherein:
said image generation step generates said virtual endoscopic image data with the direction of said endoscope as a view direction.
8. The method for processing a medical image according to claim 6 , further comprising:
identifying a tumor candidate based on said medical image data; and
receiving a sequence of observations regarding said tumor candidate to determine said traveling direction of said endoscope based on said sequence.
9. The method for processing a medical image according to claim 8 , further comprising obtaining a distance from the position of said endoscope to said tumor candidate, wherein:
said display-control step displays said distance on said display.
10. The method for processing a medical image according to claim 8 , wherein:
said display-control step generates a marker indicating said tumor candidate, superimposes said marker on a position of said tumor candidate in the virtual endoscopic image, and displays the virtual endoscopic image on said display.
