Head-mounted stereo-display microsurgery operation system

Abstract: The invention relates to a head-mounted stereo-display microsurgery operation system. The head-mounted stereo-display microsurgery operation system comprises an operation stereoscopic microscope system, a high-definition camera, an image processor, head-mounted stereo-display systems, a display, minitype cameras and image conversion switches. The high-definition camera is used for collecting operation field images through the operation stereoscopic microscope system; the collected images are converted by the image processor according to the position of an operator; erect images, which each operator can see, are displayed on the head-mounted stereo-display system of each operator; the operators can observe an operation region and the environment of an operating room by utilizing the image conversion switches and the head-mounted minitype cameras. The head-mounted stereo-display microsurgery operation system has the advantages that the structure is simple, the use is convenient, the effect is remarkable, the operability is high and the implementation is easy.

Spect image conversion device, image conversion program, and image conversion method

Abstract: PROBLEM TO BE SOLVED: To provide a method of converting a pixel value of a SPECT image into the same unit, such as Bq/mL, without measuring BCF in each facility that performs SPECT examination.SOLUTION: BCF values for each of combinations of models of SPECT devices and collimators are stored in a database. A pixel value of a SPECT image is converted into a unit of Bq/mL by use of the BCF value read from the database. Consequently, absolute quantification and comparison between facilities are enabled by use of the SPECT image without measuring the BCF values for each facility or examination. An image processing program for causing a computer to execute the method, and an image processing device for implementing the method are also provided.

Radiographic image conversion plate and radiographic image reader using it

Abstract: PROBLEM TO BE SOLVED: To provide a radiographic image conversion plate having high image quality and high durability, and a radiographic image reader using it. SOLUTION: In this radiographic image conversion plate comprising an adhesive layer, a support body, a photostimulable phosphor layer and a protective layer on a support member, the distance A of the proximate part of a stimulated light reading member arranged opposite to the protective layer and the surface of the protective layer and the length B of the end non-adhered part of a radiographic conversion panel has the relation of 0<=B<=5A.

Image conversion method and device, terminal, and storage medium

Abstract: The embodiment of the invention discloses an image conversion method and device, a terminal, and a storage medium. The method comprises the following steps: acquiring input data of a standard dynamicrange rendering image, and performing Gamma correction; converting the input data after the gamma conversion into linear brightness data corresponding to a high dynamic range rendering image format; and obtaining display brightness data of the high dynamic range rendering image according to the linear brightness data, thereby performing the image display after the format conversion. Through the image conversion method disclosed by the embodiment of the invention, the effects of stabilizing the display contrast feature in the image conversion process and reducing the computing complexity can berealized, and a screen display effect is improved.
