Publication number: 20140307522Abstract: The present technique relates to an image processing device, an image processing method, and a program allowing a grasp of an ultrasonic image with an intuitive and simplified manipulation. A probe generates an ultrasonic wave and receives a reflective wave reflected at an object. A detection unit detects one or more physical quantities of the probe. A display unit displays a tomographic image showing a cross-section of a predetermined position of the object, out of the ultrasonic image of the object generated based on the reflective wave received by the probe. A sensor information acquisition unit acquires a detection result by a sensor unit as sensor information. In a tomographic image generation unit, regarding the sensor information as a parameter, a reference tomographic image is transformed according to a change of the parameter, whereby the tomographic image to be displayed on the display unit is generated. A display control unit controls the display unit to display the generated tomographic image.Type: ApplicationFiled: November 22, 2012Publication date: October 16, 2014Applicant: Sony CorporationInventors: Koji Kashima, Tatsumi Sakaguchi, Takeshi Miyai, Hiroshi Kajihata
