Abstract

The invention relates to a two-dimensional stepping nuclear magnetic resonance apparatus bed body. The two-dimensional stepping nuclear magnetic resonance apparatus bed body comprises a transverse moving stepping motor and a longitudinal moving servo moor, and further comprises a single-chip microcomputer, and a switch key, a sensor, a coder-decoder, a stepping motor driver and a servo motor driving circuit which are connected with the single-chip microcomputer; the stepping motor driver is connected with the transverse moving stepping motor in a controlling manner, the servo motor driving circuit is connected with the longitudinal moving servo motor in the controlling manner, and the coder-decoder is also connected with the longitudinal moving servo motor. The two-dimensional stepping nuclear magnetic resonance apparatus bed body provided by the invention has the advantages that the accurate control and detection of the longitudinal and transverse movement of the bed body are realized; since a main control circuit adopts an all-digital control method and anti-interference design, the anti-interference performance is very high, the control function of the bed body can be fully realized, the testing requirements of the bed body are satisfied, the stability and reliability are higher, the production cot is greatly reduced and the production period is shortened.

Description

technical field [0001] The invention belongs to the field of medical electronics and relates to a bed body of a two-dimensional stepping nuclear magnetic resonance instrument. Background technique [0002] NMR is a physical process in which the magnetic moment of an atomic nucleus whose magnetic moment is not zero undergoes Zeeman splitting at the spin level under the action of an external magnetic field, and resonantly absorbs radio frequency radiation of a certain frequency. NMR spectroscopy is a branch of spectroscopy, its resonance frequency is in the radio frequency band, and the corresponding transition is the transition of nuclear spin on the nuclear Zeeman level. [0003] There are two types of nuclear magnetic resonance instruments currently in use: continuous wave (CN) and pulsed Fourier transform (PFT). The continuous wave nuclear magnetic resonance instrument is mainly composed of a magnet, a radio frequency transmitter, a detector, an amplifier and a recorder...
