Abstract
Description
Technical Field
[0001] This utility model belongs to the field of magnetic resonance technology, and specifically relates to a magnetic resonance imaging system. Background Technology
[0002] Magnetic resonance imaging (MRI) systems are commonly used in the medical and health fields. They utilize the nuclear magnetic resonance phenomenon that occurs when hydrogen nuclei (protons) in human tissue are excited by radio frequency pulses in a magnetic field, generating magnetic resonance signals. These signals are then processed by a computer to reconstruct an image of a specific layer of the human body.
[0003] Traditional magnetic resonance imaging (MRI) systems employ an integrated, ring-shaped magnet system. This system typically consists of a large, ring-shaped main magnet, inside which gradient coils and radio frequency (RF) coils are sequentially mounted. These components are arranged coaxially, forming a fixed imaging aperture through which the patient can enter for imaging. To ensure optimal imaging quality, the main magnet needs to provide a high-intensity and highly uniform static magnetic field (e.g., 1.5T or 3.0T), while the gradient coils are used for spatial positioning, and the RF coils are used to transmit and receive magnetic resonance signals. This structure offers advantages such as high imaging quality and wide applicability, and is therefore widely used in various clinical examinations.
[0004] In magnetic resonance imaging (MRI) applications, the patient's body (or target object) needs to be placed within the imaging area, which is determined by the structural design and component layout of the MRI system. Existing traditional integrated MRI systems employ a fixed, ring-shaped structure, where the magnet system, gradient coils, radio frequency coils, and the patient's examination bed are typically integrated into a single unit. While this design offers advantages in imaging stability and system integration, it also introduces significant inconveniences in clinical applications, particularly in patient transport. For patients with limited mobility or severe illness, transferring them from a regular hospital bed to a dedicated MRI examination bed not only requires substantial manpower but may also cause secondary injury or fluctuations in their condition. For instance, in ICU or emergency settings, many patients carry monitoring equipment or have catheters inserted. The traditional transport process is complex and the operating space is limited, making risks such as equipment entanglement and catheter dislodgement highly likely. Furthermore, to accommodate the imaging area, medical staff often need to precisely position the patient, sometimes requiring multiple adjustments, further increasing workload and examination time.

[0043] This invention provides a magnetic resonance imaging system to improve the convenience and safety of patients undergoing magnetic resonance imaging examinations, and is especially suitable for patients with limited mobility, emergency needs, or special care requirements.
[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0045] like Figure 1 and Figure 2 As shown, this embodiment provides a magnetic resonance imaging (MRI) system, which includes: a C-shaped MRI device 1 with an open imaging area; and a movable bed 2 used in conjunction with the MRI device, the middle section of which can be inserted into and placed within the open imaging area of the imaging device. Due to the C-shaped open design, patients can be laterally moved between a regular hospital bed and the movable bed 2 without the need for lifting or moving, greatly reducing the burden on medical staff and avoiding secondary harm to patients, thereby significantly improving patient experience and clinical operational efficiency.
[0046] The movable bed 2 is equipped with multiple wheels 3 for easy movement on the ground. To prevent the bed from moving or shaking during imaging, the bed is also equipped with a fixing device that can effectively brake the bed after it is in place, ensuring the overall stability of the system and the imaging accuracy.
[0047] Furthermore, the movable bed 2 is equipped with an adjustment plate 4, which can slide back and forth along the length of the bed. This structure allows for flexible adjustment of the position of the adjustment plate 4 relative to the imaging area according to the height of different patients and the required imaging area, thereby improving the accuracy of imaging positioning and examination efficiency. The adjustment plate 4 is mounted on the movable bed 2 via a guide rail structure, ensuring smooth operation during movement and avoiding errors caused by free sliding, which is beneficial for achieving precise alignment and repeatable positioning.
[0048] Two mounting areas are provided along the length of the adjustment plate 4: a first mounting area 5 and a second mounting area 6. The first mounting area 5 is located in the region from the patient's head to the waist and abdomen, and has a first mounting groove 7. The second mounting area 6 is located in the region from the patient's legs to the feet, and has two second mounting grooves 8. This partitioned design corresponds to the human body structure, providing mounting interfaces for the upper and lower body of the patient.
[0049] The first mounting slot 7 and the second mounting slot 8 are used to install a fixation mechanism, which can be one or more combinations of limiting blocks, straps, and clamps. By installing the above-mentioned fixation mechanism, the patient's key parts can be stably restricted, effectively preventing the patient from shifting position during imaging due to breathing, muscle twitching, or discomfort, thereby improving image clarity and clinical diagnostic accuracy. It is particularly suitable for children, patients in the postoperative recovery period, or those with voluntary movement disorders.
[0050] To facilitate operation by medical staff, at least one C-shaped adjustment rod 9 is provided on the adjustment plate 4, with both ends fixedly connected to the adjustment plate 4. Medical staff can grasp the adjustment rod 9 on both sides of the bed and directly push the adjustment plate 4 for adjustment. This design is simple in structure and intuitive in operation, which is conducive to rapid fine-tuning of the examination area, and is particularly suitable for emergency situations or scenarios requiring rapid imaging.
[0051] The aforementioned fixing device employs a linkage structure consisting of a rotating handle 10, a rotating rod, a limiting cam, and a limiting connecting rod. During operation, the operator rotates the handle 10, which drives the limiting cam to rotate via the rotating rod, thereby moving the limiting connecting rod until one end of the connecting rod presses against the wheel 3. This structure locks the wheel 3 in its current position, preventing it from continuing to roll, thus achieving rapid braking and release of the movable bed 2 and enhancing the safety and flexibility of the equipment during use.
[0052] To achieve rapid and accurate docking between the bed and the magnetic resonance imaging equipment, the magnetic resonance imaging equipment 1 is provided with a first docking area, and the side of the movable bed 2 is provided with a second docking area. The two are arranged opposite each other and can achieve stable docking. In actual use, medical staff only need to push the bed to the side of the equipment, and the physical positioning and alignment can be achieved through the preset docking structure, which greatly reduces positioning time and improves operational efficiency.
[0053] Preferably, at least one of the first docking area and the second docking area is provided with a positioning protrusion, and the other is provided with a positioning groove that cooperates with it. When the bed is close to the magnetic resonance equipment, the positioning protrusion automatically embeds into the corresponding groove, realizing automatic alignment and limiting, avoiding structural interference or image deviation caused by misalignment, and further improving the system's operational convenience and imaging accuracy.
[0054] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
