Patent number: 8939892Abstract: Endoscopic images and virtual endoscopic images are obtained. Then, an endoscopic image captured at a predetermined position of the anatomical structure is extracted from the obtained endoscopic images, and a comparative virtual endoscopic image virtually generated as if it is captured at a position corresponding to the predetermined position is extracted from the obtained virtual endoscopic images, and the extracted images are associated with each other. A three-dimensional position corresponding to each pixel forming the endoscopic image captured at the predetermined position is calculated based on a three-dimensional position of each pixel forming the comparative virtual endoscopic image. Then, volume data is generated from the endoscopic image captured at the predetermined position based on a pixel value of each pixel forming the endoscopic image and the three-dimensional position calculated for each pixel.Type: GrantFiled: August 30, 2011Date of Patent: January 27, 2015Assignee: FUJIFILM CorporationInventor: Masaki Miyamoto

Patent number: 8497862Abstract: A pseudo three dimensional image is generated, based on an aspect image and a mapping image generated from an original three dimensional image, using a volume rendering method. A mapping image that represents the functions of a subject is generated using first voxel data that constitute an original three dimensional medical image of the subject. An aspect image is generated using second voxel data that constitute an original three dimensional medical image of the subject. A position matching means causes positions within a heart represented by the mapping image to correspond to positions within a heart represented by the aspect image. An image generating means executes volume rendering based on degrees of opacity within the mapping image, to generate the pseudo three dimensional image.Type: GrantFiled: April 10, 2008Date of Patent: July 30, 2013Assignee: FUJIFILM CorporationInventors: Jun Masumoto, Masaki Miyamoto

Publication number: 20120033866Abstract: Structures in the vicinity of a target point (point of interest) within a diagnostic image are enabled to be observed in detail from multiple directions. Overview images (8, 9) that represent the overview of a structure (e.g., the large intestine) are generated based on volume data, and displayed on the screen (5) of a display. Points within the overview images and points corresponding thereto in the volume data are set as target points. Target volumes that include the target points and line of sight vectors within the volume data having the target points as endpoints and a movable viewpoint as a starting point are set within the volume data. The directions of the line of sight vectors are changed, and the target volumes are projected onto projection planes perpendicular to the directions of the line of sight vectors to generate detailed images (11) that represent details of the structure in the vicinity of the target points .Type: ApplicationFiled: April 15, 2010Publication date: February 9, 2012Applicant: FUJIFILM CORPORATIONInventors: Jun Masumoto, Masaki Miyamoto

Publication number: 20110242097Abstract: In generating a virtual endoscopic image, an interior of a lumen is made viewable even when the viewpoint position is changed. A virtual endoscopic image generation element generates a virtual endoscopic image by volume rendering based on three-dimensional data. An opacity curve setting element sets an opacity curve which defines the relationship between pixel values of the three-dimensional data and opacity values. A viewpoint position setting element sets a viewpoint position of a virtual endoscopic image. A movement amount determination element determines a movement amount of the opacity curve with respect to an opacity curve at a reference viewpoint position. When a virtual endoscopic image is generated by the virtual endoscopic image generation element, the opacity curve setting element sets an opacity curve obtained by moving the opacity curve by the determined movement amount in the virtual endoscopic image generation element.Type: ApplicationFiled: January 31, 2011Publication date: October 6, 2011Applicant: FUJIFILM CORPORATIONInventor: Masaki MIYAMOTO
