Description

Medical image dipperstick

Technical Field

The utility model relates to a measure image size technical field, especially relate to a medical science image dipperstick.

Background

The length of the target object on the medical image such as CT, MRI, X-ray and other images is measured by two methods, namely direct mouse-drawing measurement on computer software or contrast conversion on a medium such as film according to a scale beside the image. The former measuring method is more convenient and accurate, but is only limited to be measured on a computer and cannot measure images printed on media such as films. Although the latter measurement method can measure an image printed on a medium such as a film, when a microstructure is measured, the view is often blurred, the boundary of the microstructure cannot be aligned effectively, and finally the boundary is misaligned, which affects the accuracy of measurement.

For example, chinese patent No. CN2523373 discloses a medical CT adjustable scale, in which the body of the scale is made into a transparent body, a slidable transparent cursor with vertical lines is mounted on the body of the scale, 11 dark rays passing through the same point are made on the body of the scale, the rays divide the vertical lines of the cursor into 10 equal parts to form decimal scale, and various proportional lengths can be provided by moving the position of the cursor. However, the scale of this solution does not have a measuring claw, and the size of the image is observed through the transparent blade, and it is necessary to compare a plurality of rays, and read data with naked eyes, when measuring a microstructure, it is easy to cause inaccurate observation, and the accuracy of the measurement structure is affected.

In addition, some non-medical special scale in the prior art are also digitally displayed, and can set the scale, improve the accuracy when reading, for example, chinese patent with publication number CN201745327U discloses an electronic scale, whose surface has at least one starting point and at least one cursor, the cursor can freely and linearly move on the scale body relative to the starting point, the scale body is provided with a microcomputer processor, a displacement sensing device, a setting unit and a display unit, the displacement sensing device, the setting unit and the display unit are all electrically connected with the microcomputer processor, the displacement data relative to the starting point is transmitted to the microcomputer processor by moving the cursor, the working mode, the proportional relation and the grabbing scale can be freely set by the setting unit, the microcomputer processor converts the displacement data according to the instruction transmitted by the setting unit and the internal program, and then displays the related data by the display unit. But the electron scale of this scheme also has the defect, when measuring little structure, does not measure the claw and presss from both sides the contrast, and because the size is little difficult for distinguishing, leads to measuring error great.
