A mouse for magnetic resonance and its manufacturing method and signal transmission device

Abstract

The invention discloses a mouse for magnetic resonance, which comprises an upper shell, a lower shell, a track ball, a circuit board and cables, the inner surfaces of the upper shell and the lower shell are coated with a silver-copper conductive paint layer, and the concentration of the silver-copper conductive paint is 13 %-17%; the invention also discloses a manufacturing method and a signal transmission device for a magnetic resonance mouse. The invention can meet the clinical application of functional magnetic resonance, avoid signal interference, and ensure that the remote computer can accurately receive the response of the subject.

Description

technical field [0001] The invention relates to a medical device, in particular to a magnetic resonance mouse. Background technique [0002] Functional magnetic resonance is currently the most commonly used technology for studying brain function. In functional magnetic resonance experiments, subjects are often required to respond to stimuli. Currently, the commonly used feedback device is a keyboard with a small number of keys (2-4), so it can only send out and receive a simple response. In order to study the brain's response to complex tasks, fMRI experiments often involve more complex stimuli and require subjects to make more complex responses, while traditional keyboard feedback cannot meet the needs. [0003] The mouse is currently the most commonly used cursor indicator for human-computer interaction, but currently commercially available mice cannot be directly used in the MRI environment. First of all, the mouse contains a lot of metal parts, which will seriously aff...

Problems solved by technology

In order to study the brain's response to complex tasks, fMRI experiments often involve more complex stimuli and require subjects to make more complex responses, while traditional keyboard feedback cannot meet the needs

[0003] The mouse is currently the most commonly used cursor indicator for human-computer interaction, but currently commercially available mice cannot be directly used in the MRI environment

First of all, the mouse contains a lot of metal parts, which will seriously affect the image quality

Secondly, during magnetic resonance imaging, the rapidly switched gradient magnetic field will induce an induced current in the wire of the mouse, so that the remote computer cannot receive the response of the subject normally.
