Patent number: 9078568Abstract: 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.Type: GrantFiled: December 20, 2010Date of Patent: July 14, 2015Assignees: Kabushiki Kaisha Toshiba, Toshiba Medical Systems CorporationInventors: Kota Aoyagi, Hitoshi Yamagata

Patent number: 8306606Abstract: A differential-image creating unit creates a three-dimensional image on which an artery is highlighted and a three-dimensional image on which a tumor is highlighted. An image compositing unit combines the three-dimensional images to composite an image. A display control unit displays the composite image on a monitor. Moreover, when compositing an image, the image compositing unit composites the image such that a tumor nutrient blood-flow inside and outside tumor is to be displayed in respective different colors. Furthermore, a blood-flow quantity inside tumor measuring unit calculates a blood-flow quantity inside tumor and a ratio of the blood-flow quantity inside tumor to a tumor volume, and the display control unit displays the blood-flow quantity inside tumor and the ratio of the blood-flow quantity inside tumor to the tumor volume. Accordingly, information that is meaningful for determining malignancy of a tumor can be provided.Type: GrantFiled: January 30, 2009Date of Patent: November 6, 2012Assignees: Kabushiki Kaisha Toshiba, Toshiba Medical Systems CorporationInventors: Kota Aoyagi, Hitoshi Yamagata, Takehiro Ema, Kyoko Sato, Shunsuke Satoh

Patent number: 7991108Abstract: A cardiac cavity region specifying part specifies the position of a cardiac cavity region represented in volume data. An image generation plane determining part determines an image generation plane that includes a rotation axis intersecting the cardiac cavity region. With a direction orthogonal to the image generation plane as a view direction, a first image generator generates three-dimensional image data that three-dimensionally represents a region excluding the cardiac cavity region, based on data excluding data included in the cardiac cavity of the volume data. A second image generator generates two-dimensional image data that two-dimensionally represents a region in the image generation plane, based on the data excluding the data included in the cardiac cavity region of the volume data. An image synthesizer synthesizes the three-dimensional image data with the two-dimensional image data. A display controller causes a display to display the synthesized image.Type: GrantFiled: July 6, 2009Date of Patent: August 2, 2011Assignees: Kabushiki Kaisha Toshiba, Toshiba Medical Systems CorporationInventors: Takehiro Ema, Hitoshi Yamagata, Kota Aoyagi, Kyoko Sato, Shunsuke Satoh
