CN2297980Y - Auxiliary coordinate ruler for X-ray film focus or foreign matter locating - Google Patents

Abstract

The utility model relates to an auxiliary coordinate ruler for X-ray film focus or foreign matter locating, which is a net composed of the interweaving of an abscissa line (1) and an ordinate line (2). When the X-ray film is shot, the coordinate ruler is arranged at the horizontal position of the focus or the foreign matter, the shot picture has obvious projection of the coordinate ruler, and the position of the focus or the foreign matter and the size thereof and the shape are stuck out a mile. If the coordinate ruler is arranged at the side position of the focus or the foreign matter again, and the depth of an opposite body surface of the focus or the foreign body can be reflected by the shot picture.

Description

X-ray is taken the photograph sheet focus or foreign body location auxiliary block scale

This utility model belongs to a kind of medical auxiliary apparatus, particularly belongs to a kind of when taking the X-ray sheet, in order to determine the coordinatometer of focus or the accurate position of foreign body.

Aspect medical, taking the X-ray sheet is a kind of important pathological diagnosis supplementary means.Mainly, observe its shape and size, determine its position and the degree of depth in order to intravital focus of finder or foreign body.Because x-ray fluoroscopy is unidirectional, it is the plane that X-ray is taken the photograph sheet, and the ratio between image and material object is not certain, does not also have any object of reference, desires to judge that exactly the size of focus or foreign body and position thereof are extremely difficult.

The purpose of this utility model is to provide a kind of X-ray to take the photograph sheet focus or foreign body location auxiliary block scale, in order to determine size dimension, corresponding body surface position and the degree of depth thereof of people's internal lesions or foreign body exactly.

X-ray is taken the photograph sheet focus or foreign body location auxiliary block scale, is by the vertical grid that is interwoven with the ordinate line of abscissa line, and so-called abscissa line and ordinate line are the silks made from the X-ray developing material.

When taking the X-ray sheet, this coordinatometer is placed focus or foreign body horizontal position, the photo of shooting has tangible coordinatometer projection, and residing position of focus or foreign body and size thereof and shape come into plain view.If coordinatometer is placed the side position of focus or foreign body, the photo of shooting can reflect the degree of depth of focus or the relative body surface of foreign body again.Two photo binding analysis can be measured the volume of focus or foreign body.

Accompanying drawing is the coordinatometer front view.

As shown in drawings, X-ray is taken the photograph sheet focus or foreign body location auxiliary block scale, abscissa line (1) that the useful metal silk is made and ordinate line (2).Can certainly use other X-ray developing materials,, or have other filaments of developing agent as glass fibre etc.

X-ray is as shown in the figure taken the photograph sheet focus or foreign body location auxiliary block scale, and also design has locating hole (3), is used for the location of coordinatometer with respect to body surface, also is convenient to be easy to place with the assembling of coordinatometer holding frame.

Claims (2)

1, X-ray is taken the photograph sheet focus or foreign body location auxiliary block scale, be characterised in that, and be by abscissa line (1) and the vertical grid that is interwoven of ordinate line (2), so-called abscissa line and ordinate line are the silks made from the X ray developing material.

2, X-ray according to claim 1 is taken the photograph sheet focus or foreign body location auxiliary block scale, and its feature also is, has locating hole (3).
