Objective To design and develop a simple laser locator for rats and mice, and to provide a safe, convenient, accurate, low-cost and easy-to-operate experimental tool for medical nuclear magnetic resonance experiments.
Methods The plexiglass plate and the laser locator were assembled to make a small animal laser locator.
Results Compared with other similar products, the mouse laser locator has the advantages of simple production, safety, basically meeting the experimental requirements, and low price.
Conclusion The small animal laser locator plays a positive role in the MRI examination of small animals, which greatly shortens the experiment time and improves the accuracy of the placement of the experimental animals, which provides a strong guarantee for the next step in the MRI scan of the experimental animals.
