The invention relates to a light-emitting diode sleep regularizer, which is characterized in that it includes a base that matches the neck of a human body, at least one LED component arranged on the base, a control circuit, and a control circuit connected between the control circuit and the LED component. switchgear. The sleep regularizer uses light waves to stimulate the nervous tissue in the light-sensitive parts of the human body's high spinal cord and hypothalamus, thereby correcting abnormal sleep patterns. At the same time, the light waves penetrate the back and side skin of the head and neck without Cause visual fatigue so as to avoid vision damage induced by strong light effect. At the same time, the product is battery-driven, easy to carry, and its structural design matches the shape of the human neck, allowing users to wear it freely in daily life.

The invention relates to a local coil positioning method, a magnetic resonance system and a computer readable storage medium. The local coil positioning method comprises the steps of acquiring first position information based on relative position information between a local coil and an imaging space of the magnetic resonance system; displaying a mark representing the local coil on an operation interface according to the first position information; receiving the mark selected on the operation interface; and moving the local coil corresponding to the selected mark to the imaging space. Accordingto the invention, the distance between the local coil and the imaging space is acquired, and thus the local coil is moved to the imaging space, so that the accuracy is greatly improved.
