Abstract:
A method and an apparatus for measuring a coarseness level in a target organ from an ultrasound visual image are provided conveniently to measure fibrosis of the organ at lost cost. A method for measuring a coarseness level in a target organ from an ultrasound visual image includes the steps of: obtaining an ultrasound area visual image of the organ(S210); (b) setting a target area for the ultrasound area visual image(S220); obtaining a quantified representative roughness level of the target area from distribution of luminance values of pixels within the target area(S230); and calculating the coarseness level of the organ corresponding to the quantified representative roughness level(S240).
Abstract:
An active ion-doped waveguide-plasmon resonance (AID WPR) sensor based on plasmon surface resonance (PSR) and an imaging system using the sensor are provided. An additional dielectric thin film doped with active ions and acting as a waveguide is formed on a metal thin film. The active ions are excited by an incident light beam and fluoresce light of a shorter wavelength than the incident light beam through upconversion coupled to surface plasmon resonance, thereby increasing fluorescence intensity variations with respect to incident light angle variations. The AID WPR sensor and the imaging system can detect a minor refractive index variation of a sample, which could not be measured using an existing SPR sensor, or a trace adsorbed material, with 100 times larger refractive index resolution than the existing SPR sensor.

PURPOSE: A waveguide-plasmon resonance sensor and an image system are provided to improve sensitivity of the waveguide-plasmon resonance sensor by coating a dielectric thin film doped with active ions on a metal layer as a waveguide. CONSTITUTION: An active ion doped waveguide-plasmon resonance sensor includes a conductive film(122) for providing surface plasmon and a dielectric medium(110) aligned at one side of the conductive film(122). A light source(130) radiates incident light, which is incident into the conductive film(122) through the dielectric medium(110). A dielectric film is coated on the other side of the conductive film(122). A sample(123) is attached to the dielectric film. Active ions(171) are doped into the dielectric film. Active ions(171) are excited by incident light(131), thereby generating fluorescent light(139). A light receiving section(140) is provided to measure intensity of fluorescent light(139).

Abstract:
PURPOSE: A method for correcting bone density and a recording medium read by a computer for storing a correction program are provided to correct a variation of radius density due to a variation of conditions by using a phantom of an X-ray image. CONSTITUTION: An image including a target and phantoms having two or more regions of different thickness is obtained(S101). The bone density of the target of the image and an average gray level of each region of the phantoms are calculated(S103). A correlation between the bone density of the target of the image and the average gray level of the regions of the phantoms is extracted by repeating the above processes as much as N number(S105). A variation of radius density due to a variation of conditions in an X-ray inspection process is corrected by using the correlation(S107).
