Figure 3 As shown, the existing magnetic resonance imaging device includes a scanner 1 and a host unit with a display connected to the scanner (not shown in the figure). The host unit allows medical staff to set scanning parameters. The patient is placed in the central, enclosed, narrow, hollow scanning chamber 2 of the scanner for scanning. The scanned images are displayed on the monitor.
[0003] The scanning chamber 2 of the scanner is used for a relatively long time, and patients have to endure considerable machine noise. This claustrophobic environment can easily cause patients to experience claustrophobia and feelings of oppression, making it difficult for some to cooperate with the scan. Furthermore, during the scan, doctors can only view the images on a monitor and cannot see the actual condition of the patient, such as whether they are experiencing excessive tension or difficulty breathing, which can have adverse effects.

[0022] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically describe the magnetic resonance imaging device of this utility model.
[0023] Example
[0024] Figure 1 This is a schematic diagram of the magnetic resonance imaging device in an embodiment of this utility model. Figure 1 ; Figure 2 This is a schematic diagram of the magnetic resonance imaging device structure in an embodiment of this utility model. Figure 2 .
[0025] like Figure 1 and Figure 2 As shown, this embodiment provides a magnetic resonance imaging device 100, including a scanner 1, a main unit, a first camera unit 10, a first display unit 20, a second camera unit 30, a second display unit 40, and a power supply unit (not shown in the figure).
[0026] The scanner 1 is used to perform magnetic resonance scanning on the patient. The scanner 1 and the host computer with a display are the same as those in existing magnetic resonance imaging devices.
[0027] The second camera unit 30 is disposed on the top of the housing of the scanner 1 and is used to capture images of the environment above and around the scanner 1. The second camera unit 30 includes at least one second camera 31.
[0028] The second display unit 40 is disposed within the scanning chamber 2 of the scanner 1 and connected to all the second cameras 31. It is used to display images captured by the second cameras 30 to the patient located within the scanning chamber 2. The second display unit 40 is a curved display screen, the curvature of which is the same as the curvature of the inner wall of the scanning chamber 2. It is disposed on the inner wall of the scanning chamber 2 and positioned directly above the patient's head. When the patient is placed within the scanning chamber 2 for scanning, their head is in a fixed position, and the second display unit 40 is positioned directly above this fixed position.
[0029] In this embodiment, the second camera 31 is positioned corresponding to the position of the curved display screen, and is located above the vertical projection of the curved display screen.
[0030] The first camera unit 10 is disposed within the scanning chamber 2 and is used at least to capture images of the patient's head. The first camera unit 10 includes at least one first camera 11, which is disposed on the inner wall of the scanning chamber 2 and positioned above the patient. In this embodiment, the first camera unit 10 includes three first cameras 11, which are located at different positions near the second display unit 40. Two first cameras 11 are located on the left and right sides of the second display unit 40, respectively, and the third first camera 11 is located on the side of the second display unit 40 closer to the patient's head and further away from the patient's body. The three first cameras 11 allow for the capture of an image of the patient's entire upper body.
[0031] The first display unit 20 is disposed outside the scanner 1 and connected to all the first cameras 11, for displaying the images captured by the first camera units 10 to the doctor. The first display unit 20 may be a second display screen 21 disposed on the casing of the scanner 1, or a display integrated into the host unit (i.e., the display shows both the images scanned by the scanner 1 and the images captured by the first camera units 10).
[0032] In this embodiment, both the curved display screen and the second display screen 21 are touch screens.
[0033] The power supply unit provides power to the first camera unit 10, the first display unit 20, the second camera unit 30, and the second display unit 40.
[0034] The process of using the magnetic resonance imaging device 100 is as follows:
[0035] The patient is transported to a predetermined position in scanner 1 via a scanning bed, with the patient's head directly below the curved display screen. Scanner 1 is activated to begin scanning, and the curved display screen shows the patient an external image captured by the second camera 30, thus alleviating the patient's fear of confinement and feelings of oppression. Simultaneously, the first camera 10 takes a picture of the patient, and the doctor views the scan results on the main unit's built-in monitor and observes the patient's facial expressions and upper body movements through the first display unit 20 until the scan is complete.
[0036] The role and effect of the embodiments
[0037] According to the magnetic resonance imaging device involved in this embodiment, since it also includes a first camera unit and a first display unit on the basis of the original scanner and host, the first camera unit is set in the scanning chamber and can take pictures of the patient's head. The first display unit is set outside the scanner and connected to the first camera unit, and can display the images taken by the first camera unit to the doctor. Therefore, during the scanning process, the doctor can observe the expression of the patient being examined in real time, so as to respond in a timely manner.
[0038] Furthermore, the magnetic resonance imaging device also includes a second camera unit and a second display unit. The second camera unit is located on the outside of the scanner and can capture images of the environment above and around the scanner. The second display unit is located inside the scanning chamber and is connected to the second camera unit. It can display the images captured by the second camera unit to the patient located inside the scanning chamber. These images are equivalent to (simulating) what the patient would see if they were not in a claustrophobic scanning chamber while maintaining the same posture. This alleviates the patient's fear of confinement and sense of oppression, ensures the sequential execution of the scanning examination, and improves the patient's examination experience.
[0039] Furthermore, because the first camera is set on the inner wall of the scanning chamber and above the patient, it facilitates the taking of pictures of the patient's head.
[0040] Furthermore, because the second display unit is a curved display screen with the same curvature as the inner wall of the scanning chamber, it is easy to install on the inner wall of the scanning chamber and located directly above the patient's head, making it convenient for the patient to view the images captured by the second camera unit during the scan.
[0041] Furthermore, since the first camera unit includes three first cameras, two of which are located on the left and right sides of the second display unit respectively, and the other first camera is located on the side of the second display unit that is closer to the patient's head and farther away from the patient's body, it is convenient to take pictures of the patient's head and upper body.
[0042] Furthermore, because the second camera is positioned on top of the scanner housing and corresponds to the location of the curved display screen, it can better simulate the view seen by the patient when maintaining the same posture and not in a claustrophobic scanning chamber, thus improving the patient's experience.
[0043] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
