摘要:
Surgical operation supporting apparatus and method is disclosed in which based on a high-definition tomographic images of an operation site produced before surgery, a three-dimensional model of the operation site is generated, and a surface of the operation site is optically measured during the surgical operation, and further, first position information that represents a three-dimensional position of each of points on the surface is acquired. An unexposed portion of the operation site is measured with ultrasonic waves during the surgical operation, and second position information that represents a three-dimensional position of each of points in the unexposed portion is acquired. Based on the first position information and the second position information, displacement and distortion at a portion whose three-dimensional position is not known in the three-dimensional model is estimated to obtain an estimated result. The three-dimensional model is re-corrected by use of a finite element method and the estimated result.

摘要:
Presentation of images showing with high resolution the state of a surgical field during surgery is realized with a simple configuration. When performing surgery, a three-dimensional model is generate based on MRI images of a patient captured prior to surgery, and three-dimensional coordinates of each location on a surface of the patient are measured by scanning a laser beam over the surface and detecting laser beam reflected therefrom, and correspondence is made with the MRI image for each location of the surface (frameless/markerless: steps 100 to 116), the position of a surgical instrument is also detected by the laser beam, the position of the surgical instrument derived, and images of the surgical instrument combined onto the MRI images and displayed during surgery (steps 120 to 130).

Surgical operation supporting apparatus and method is disclosed in which based on a plurality of high-definition tomographic images of an operation site produced before surgery, a three-dimensional model of the operation site is generated, and a surface of the operation site is optically measured during the surgical operation, and further, first position information that represents a three-dimensional position of each of points on the surface of the operation site is acquired. Further, an unexposed portion of the operation site is measured with ultrasonic waves during the surgical operation, and the second position information that represents a three-dimensional position of each of points in the unexposed portion of the operation site is acquired. Moreover, based on the first position information and the second position information, displacement and distortion occurring at each of the points in the operation site are estimated using the generated three-dimensional model. And then, in accordance with the estimated displacement and distortion occurring at each of the points in the operation site, the plurality of high-definition tomographic images of the operation site produced before the surgical operation are corrected and the corrected high-definition tomographic images are displayed.

Provided is a method of fabricating a secondary battery including a battery case and an electrode plate set housed in the battery case. The electrode plate set includes positive and negative electrode plates and a separator interposed therebetween. The electrode plate set is impregnated with non-aqueous electrolyte. The method includes the steps of: replacing air in the battery case with gas having an Ostwald solubility coefficient of 2.0 or more in the non-aqueous electrolyte; reducing the pressure in the battery case after the replacement with the gas; and introducing the non-aqueous electrolyte into the depressurized battery case.
摘要:
After a ferroelectric capacitor is formed, an Al wiring (conductive pad) connected to the ferroelectric capacitor is formed. Then, a silicon oxide film and a silicon nitride film are formed around the Al wiring. Thereafter, as a penetration inhibiting film which inhibits penetration of moisture into the silicon oxide film, an Al2O3 film is formed.
