Anti-fragmentation system and method for slice loading of slice scanner

Abstract

The invention relates to a slice loading anti-crushing system of a slice scanner and a method thereof. The slice loading anti-crushing system comprises a stepping motor, a push rod, a sensor set, an encoder, a loading platform, an upper system and a control system; wherein the stepping motor is connected with the push rod; the sensor set comprises a plurality of sensors, one sensor is arranged atthe position where the push rod is completely pulled back, another sensor is arranged on a pre-set point of the loading platform, the carrying platform is arranged in front of the pushing rod, the encoder is used for counting the stepping motor, and the upper system is connected with the encoder, the sensor set and the control system respectively. The method has the advantages that by arranging the sensor set and the encoder, the moving distance can be accurately calculated, and the conveying error can be reduced. The abnormal situation can be accurately judged, and the system is used to process timely to prevent the slice from being damaged. The slice is protected, and the slice integrity is greatly improved.

Description

technical field [0001] The invention relates to the technical field of slice loading anti-shattering, in particular to a slice loading anti-shattering system and method of a slice scanner. Background technique [0002] The use of slice scanners can obtain high-speed, accurate, out-of-focus, and reproducible digital slice information, which has attracted extensive attention from scientific research and medical circles. [0003] Currently, slice scanners transport slices by using a stepping motor to control the push rod to push the slices from the slice storage container (ie slice box) to the slide platform; Pull up back into the slice storage container. [0004] The working principle of the stepping motor is as follows: the actual distance of the push rod = the distance of the motor running one circle * the number of pulses sent to the motor. The distance for the stepper motor to rotate one circle is X, and the number of pulses at this time is n=L / X; in theory, as long as t...

AI Technical Summary

Problems solved by technology

[0004] The working principle of the stepping motor is as follows: the actual distance of the push rod = the distance of the motor running one circle * the number of pulses sent to the motor. The distance for the stepper motor to rotate one circle is X, and the number of pulses at this time is n=L / X; in theory, as long as the computer control terminal sends n pulses, the slice can be completely pushed from the slice box to the slice into the slot ; However, in actual operation, although the computer control terminal sends n pulses, due to the progress of the stepping motor or the resistance of the slices, the slices are not completely pushed into the slot. Subsequent actions at the expected location will result in fragmented slices

[0005] For various reasons, tiles cannot be loaded properly

If L cannot be accurately calculated, resulting in a deviation in the number of pulses n; if there is an error in the actual movement, the distance of L cannot be reached through n pulses; it cannot be correctly judged whether the slice is in place, resulting in the slice being broken when the next action is performed

[0006] Therefore, there is an urgent need for a slice scanner slice loading anti-shattering system and method thereof that can judge whether the slice is completely in place and whether the slice is moved in place, so that the slice movement is safer and more accurate, and there is no report about this method at present
