Abstract
抽样图的方法一种利用Ｘ光机直接获取Ｘ光光栅抽样图的方法。其特征是利用摄影机（Ｘ光机，Ｘ光荧光缩影机等），在原底片［２］的药膜面上安装一块紧贴的Ｒｏｎｃｈｉ光栅［１］，直接对Ｘ光进行光栅抽样。Ｒｏｎｃｈｉ光栅的位置固定不变。拍片时只需曝光一次。当你得到一张底片时，人体内肉眼看不到的器官图象信息也就编码完毕。可减少一道工序。使图象的光栅抽样支术变得十分简单，省时，省力，省钱。
The sampling image method is a method of directly obtaining the X-ray raster sampling image by using an X-ray machine. It is characterized in that a camera (X-ray machine, X-ray fluorescence miniature machine, etc.) is used to install a close-fitting Ronchi grating [1] on the film surface of the original negative film [2] to directly sample the X-ray grating. The position of the Ronchi grating is fixed. Only one exposure is required for filming. When you get a negative, the image information of the invisible organs in the human body is also encoded. One process can be reduced. The image raster sampling technique becomes very simple, saving time, labor and money.
Description
The invention belongs to the white light information treatment technology of image.
General optical image pseudo-color coding technique, all must give a soot-and-whitewash is arranged earlier, make an egative film (negative film) with this soot-and-whitewash through imaging method or after directly duplicating method carries out pseudocolor encoding, exposure, flushing then, use this egative film (negative film) to be put into then and carry out filtering Jie sign indicating number acquisition color image on the optical information processing system.The shortcoming of this treatment technology is can not directly be put into pending soot-and-whitewash to carry out filtering Jie sign indicating number on the optical information processing system, obtains color image, needs to increase the operation of producing an egative film of encoding together.The present invention has done improved at above-mentioned shortcoming exactly.
Accompanying drawing is to be that the X-ray machine that utilizes of example directly obtains the synoptic diagram of raster sampling drawing method with the x-ray fluorescence machine microcosm.(1) Ronchi grating for increasing newly among the figure, (2) are egative film.
Be furnished with a HD-70mm automatic photograph machine on the homemade X-ray machine, when taking pictures, the X-ray that sees through human body is mapped on the fluorescent screen, and a branch of fluorescent (visible light) that sends is divided into two bundles by the prism of a plated film.One beam intensity is that 10% fluorescent (visible light) enters TV camera, the dynamic change of Direct observation patient intracorporeal organ on the gamma camera screen, one beam intensity is that 90% fluorescent (visible light) is injected the automatic photograph machine and taken pictures (automatic photograph machine optical system diagram slightly), and its egative film specification is 70 * 70mm
2Common fluorescent panchromatic film.Time shutter is divided into five grades: 1/second, 2/second, 3/second, 4/second, 5/second, can clap one separately, and also can take continuously.
X-ray fluorescence machine microcosm also is that the X-ray that sees through human body is squeezed into fluorescent screen, sends to project the exposure of fluorescent epitome egative film again behind the fluorescent (visible light) and take (as Figure of description).Chang Yong fluorescent spot film specification is 100 * 100mm clinically
2, also can be a little bit smaller.
Main points of the present invention are to utilize former video camera (X-ray machine, x-ray fluorescence machine microcosm etc.), in the automatic photograph machine of X-ray machine on the position of dress fluorescent panchromatic plate (egative film exposure position).Or adorn in the x-ray fluorescence machine microcosm on the position of fluorescent epitome egative film, a corresponding Ronchi grating of size is installed, the medicine face of grating and the medicine face of egative film are close together.The position of Ronchi grating can immobilize.In X-ray machine when film making, can only need exposure once, at this moment the organ picture information that is invisible to the naked eye of inside of human body also just coding finish, the egative film that develops by the darkroom is an image through raster sampling afterwards.This egative film can directly be put into and carry out filtering Jie sign indicating number on the optical information processing system, just can obtain false color image.
The invention has the advantages that takes pictures and encode carries out simultaneously, finishes simultaneously.When you obtained a photographic negative, the picture information in the egative film had encoded.Do not need pending image handled again and be made into other egative film, reduce by a procedure significantly, make the raster sampling technology of image become very simple, save time, laborsaving, economical, make this technology more be imbued with practicality, Practical significance is bigger on clinical medicine.
Claims (3)
1, a kind of raster sampling method is characterized in that utilizing video camera (X-ray machine, x-ray fluorescence machine microcosm etc.), and a Ronchi grating (1) of being close to is installed on the medicine face of original negative (2), directly X-ray is carried out raster sampling.
2, according to the described a kind of raster sampling method of claim 1, the position that it is characterized in that the Ronchi grating is changeless.
3,, with the same usually, only need exposure once when it is characterized in that video camera (X-ray machine, x-ray fluorescence machine microcosm etc.) film making according to claim 1 and 2 described a kind of raster sampling methods.
