Description
Technical Field
The present invention relates to a Magnetic Resonance Imaging (MRI) system, and more particularly to a fixing mechanism for fixing a flexible coil unit of an MRI system on a patient.
Background
Magnetic resonance imaging is a non-invasive imaging technique that can be used to visualize detailed tissue structures within a patient. The displayed tissue structure may provide valuable information to aid in the diagnosis and treatment of various diseases.
Before the MRI system scans the patient, a flexible coil unit, such as a torso coil unit, a musculoskeletal coil unit or a sensor flexible coil unit, is typically placed on the body of the patient lying on the table of the MRI system and held in place by means of a securing mechanism to complete the scan. Conventional securing mechanisms generally include two straps, an inverted T-shaped clip attached to an end of each of the two straps, and two dovetail slots formed in the table top. An enlarged-sized portion is formed at one end of the two dovetail grooves to insert or release the inverted T-shaped clip into or from the corresponding dovetail groove.
Before scanning, the inverted T-shaped clip must be inserted into the corresponding dovetail groove from an enlarged-size portion formed at one end of the dovetail groove and moved along the dovetail groove toward a position where the flexible coil unit is placed. At this position, the two straps are pulled and connected together at their free ends in a known manner to hold the flexible coil unit in place on the patient's body. After scanning, the two strips are unfastened and the inverted T-shaped clip is moved along the dovetail slot toward the increased-size portion to release the inverted T-shaped clip from the dovetail slot and remove the flexible coil unit from the patient's body. The insertion and release of the inverted T-shaped clip is cumbersome and inconvenient for the operator. Furthermore, since the dovetail slots are typically machined in a table, it is very difficult to form the dovetail slots and control their quality. Moreover, if the dovetail groove forming a portion of the table is damaged, the table is replaced in its entirety.
Accordingly, there is a need for improvements to conventional securing mechanisms for securing a flexible coil unit of an MRI system to a patient.

According to an aspect of the present invention, there is provided a fixing mechanism for fixing a flexible coil unit of an MRI system on a patient, the fixing mechanism comprising:
-an obliquely shaped clip comprising a first portion and a second portion arranged to form an oblique angle therebetween, wherein the first portion is configured to be arranged with a strap, wherein the clip is forced along the strap when the flexible coil unit is secured on a patient; and
-an elongated slot provided at a longitudinal side of a housing of a spine coil unit of the MRI system and formed at least in part by the housing of the spine coil unit, the elongated slot being configured to accommodate the second portion of the clip in an inclined shape and further configured to allow the second portion of the clip in an inclined shape to abut against a side wall of the elongated slot by a force along the strap.
According to another aspect of the present invention, there is provided a fixing mechanism for fixing a flexible coil unit of an MRI system on a patient, the fixing mechanism comprising:
-an obliquely shaped clip comprising a first portion and a second portion arranged to form an oblique angle therebetween, wherein the first portion is configured to be arranged with a strap, wherein the obliquely shaped clip is forced along the strap when the flexible coil unit is secured on a patient; and
-an elongated slot provided at a longitudinal side of a housing of a table top of the MRI system and formed at least in part by the housing of the table top, the elongated slot being configured to accommodate the second portion of the clip in an inclined shape and further configured to allow the second portion of the clip in an inclined shape to abut against a side wall of the elongated slot by a force along the strap.
According to the present invention, the clip may be inserted into or released from the elongated slot at any position along the longitudinal direction of the housing of the spine coil unit or the table top, for example, directly into or released from the elongated slot at an active position where the clip is positioned for fixing the flexible coil to a predetermined position on the patient. Thus, the insertion and release of the clip is very convenient and easy for the operator.
Preferably, the elongate slot is shaped to cooperate with the second portion of the clip, which facilitates smooth insertion or release of the second portion of the clip into or out of the elongate slot.
Preferably, the second portion of the clip is arcuate, which more reliably prevents the second portion of the clip from being released from the elongate slot. Preferably, the second portion of the clip includes a first toothed surface, the side wall of the elongate slot facing the first toothed surface includes a second toothed surface, the first toothed surface engaging the second toothed surface when the second portion of the clip abuts the side wall of the elongate slot. The engagement between the first toothed surface and the second toothed surface further prevents the clip from being inadvertently pulled out of the slot.
Preferably, the surfaces of the second portion of the clip and the groove facing each other are roughened to increase the friction between them when the second portion of the clip abuts the side wall of the elongate groove.
Preferably, the clip further comprises a supported portion protruding from a connecting portion of the first and second portions, the supported portion being supported by the housing when the clip is inserted into the elongated slot. The supported portion may prevent the second portion from being damaged by reducing a force acting on the second portion.
Preferably, the clip further comprises a projection extending from a bottom of the first portion, the housing comprising an elongate receiving groove for receiving the projection when the clip is inserted into the elongate slot. By receiving the projection into the elongated receiving groove, the clip can be further prevented from coming out of the groove.
Preferably, the elongate slot is defined by the housing and elongate body. Thus, the elongate slot is defined by two separate parts. Preferably, the housing comprises a support portion projecting laterally from each side of the main body of the housing in the longitudinal direction thereof, the elongate body being removably secured on the support portion such that the elongate slot is defined between the main body of the housing and the elongate body. When one of the two members is damaged, there is no need to replace both of them.
Preferably, the support portion defines an elongate cavity with the main body of the housing to accommodate the elongate body. Thus, the elongate body is not visible from the housing.
Preferably, an engagement mechanism is formed between the elongate body and the support portion which facilitates rapid positioning and assembly of the elongate body.
Preferably, the clip further comprises a projection extending from a bottom of the first portion, the elongate body comprising an elongate receiving channel for receiving the projection when the clip is inserted into the elongate slot. By receiving the projection into the elongated receiving groove, the clip can be further prevented from coming out of the groove.

Detailed Description
A Magnetic Resonance Imaging (MRI) system generally comprises a housing defining an examination space for accommodating a patient to be examined, a magnetic field generating system for generating a magnetic field within the examination space, and an electromagnetic resonance receiving system comprising at least one dedicated receiving coil unit. Prior to scanning, the patient lies on the table of the MRI system, and the coil unit is placed on the patient and held in place by a fixing mechanism. The patient lying on the table is then transported into the examination space to be scanned and imaged. After the scan, the patient lying on the table is transported out of the examination space and the coil unit is released from the patient. The present invention relates generally to the fixation of a coil unit on a patient, and more particularly to a fixation mechanism for fixing a flexible coil unit of an MRI system on a patient. Other components of the MRI system are well known and therefore their description is omitted here.
Fig. 1 schematically shows a table top of an MRI system and a spine coil unit placed on the table top, wherein the spine coil unit is provided with a fixation mechanism according to the invention for fixing a flexible coil unit of the MRI system on a patient. Fig. 2 is an exploded perspective view of the table top and the spine coil unit shown in fig. 1. Although the table top 1 of the MRI system can directly support the patient, as shown in fig. 1 and 2, the spine coil unit 3 is always placed on the table top 1, because the spine coil unit 3 is too heavy to be easily handled. Therefore, when performing a scan, the patient typically lies on the spine coil unit 3 placed on the table top 1. A flexible coil unit (not shown), such as a torso coil unit, a musculoskeletal coil unit or a sensor flexible coil unit, is placed on a patient lying on the spine coil unit 3 and held in place by a securing mechanism 5 according to the invention for securing the flexible coil unit on the patient. The fixation mechanism 5 for fixing the flexible coil unit on the patient according to the present invention comprises two straps 7 and a clip 9 attached to an end of each of the two straps 7. Fig. 3 is a perspective view schematically showing the clip 9 of the fixing mechanism according to the present invention. As shown in fig. 3, the clip 9 includes a first portion 9a and a second portion 9 b. The second portion 9b extends from the first portion 9a and is inclined with respect to the first portion 9 a. Preferably, the clip 9 is substantially 7-shaped. More preferably, the angle between the first portion 9a and the second portion 9b is not equal to 90 °. In other words, the clip 9 is of an inclined shape. One end of the strap 7 is attached to the first portion 9 a. An aperture 9c may be formed at the first portion 9a to accommodate the strap 7. Of course, the strap 7 may be fixed directly at the first portion 9 a. The fixation mechanism 5 for fixing the flexible coil unit on a patient according to the invention further comprises two elongated slots 11 defined in each longitudinal side of the spine coil unit 3 for receiving the second portion 9b of the respective clip 9.
Fig. 4 is a partial cross-sectional view of the spine coil unit, schematically illustrating the slots for receiving the clips 9 of the fixation mechanism 5. The spine coil unit 3 includes a housing 13 and a spine coil (not shown) housed within the housing 13. The housing 13 further includes a main body 14 and support portions 15 laterally protruding from each side of the main body 14 along a longitudinal direction of the main body 14. The longitudinal direction of the body 14 of the housing 13 is the same as the longitudinal direction XX of the table top 1 as shown in figure 2. The elongate body 17 may be removably secured to the support portion 15 by a screw 19 such that the elongate slot 11 is defined between the main body 14 of the housing 13 and the elongate body 17. When the flexible coil is placed and secured on the patient, the clip 9 is in the active position in which the second portion 9b of the clip 9 is inserted and retained in the elongated slot 11, while the first portion 9a of the clip 9 is subjected to an upward force. The elongate slot 11 is preferably inclined relative to a plane P on which the top 14a of the main body 14 of the housing 13 lies, as shown in figure 4. In one embodiment the elongated slot 11 is arranged at an oblique angle to cooperate with the top surface of the table top or the spine coil, which cooperates with the obliquely shaped clip 9 when the clip 9 is inserted into the elongated slot 11. The width of the elongate slot 11 is slightly greater than the thickness of the second portion 9b of the respective clip 9 so that the second portion 9b of the respective clip 9 is freely inserted into the elongate slot 11 or released from the elongate slot 11 when the respective strap 7 is in the inoperative condition. In the inactive state, the respective strip 7 is unstressed and slack. Fig. 5 is a sectional view similar to fig. 4 with the clip of the securing mechanism inserted into the slot and in an active state. Fig. 6 is a partial perspective view of the spine coil unit, schematically illustrating the clips of the securing mechanism inserted into the slots. As shown in fig. 5 and 6, when the flexible coil unit is placed on the patient, the second portion 9b of the respective clip 9 is inserted into the elongate slot 11 defined between the main body 14 and the elongate body 17 of the housing 13. In the active state, the two straps 7 are pulled out and connected together to hold the flexible coil unit in place on the patient. At the same time, a force (such as an upward pulling force) is applied to the respective strap and thus to the first portion 9a of the clip 9, causing the clip 9 to move until the second portion 9b of the clip 9 abuts the side wall of the elongate slot 11, thereby preventing the second portion 9b of the clip 9 from being released from the elongate slot 11.
The second portion 9b of the clip 9 and the elongate slot 11 may have a similar shape, i.e. the elongate slot 11 may be shaped to cooperate with the second portion 9b of the clip 9. As shown in fig. 3, the second portion 9b of the clip 9 is substantially arcuate. Similarly, the elongate slot 11 is also substantially arcuate to cooperate with the substantially arcuate second portion 9b of the clip 9. The engagement between the substantially arcuate second portion 9b and the substantially arcuate elongated slot 11 more reliably prevents the second portion 9b of the clip 9 from being released from the elongated slot 11 when the strap 7 is in the active condition. It is of course also possible that the second portion 9b of the clip 9 and the elongated slot 11 are both straight.
The surface 9d of the second portion 9b of the clip 9 facing the elongated body 17 may be provided with one or more teeth 9 e. Similarly, the surface 17a of the elongated body 17 defining the elongated slot 11 may also be provided with one or more teeth 17 b. The surface 17a of the elongated body 17 forms side walls defining the elongated slot 11. When the second portion 9b of the respective clip 9 is inserted into the elongate slot 11 and the strip 7 is in the active condition, the toothed surface 9d of the second portion 9b engages the toothed surface 17a of the elongate body 17 to prevent the second portion 9b of the clip 9 from being inadvertently pulled out of the slot 11. Furthermore, the surface 17a of the elongated body 17 and the surface 9d of the second portion 9b of the clip 9 may be roughened to increase the friction between them.
The support portion 15 and the main body 14 of the housing 13 together may define an elongate cavity 21 for receiving the elongate body 17. A screw 19 can be screwed into the elongated body 17 through a hole 23 in the support portion 15 to fix the elongated body 17 to the support portion 15. In order to quickly and properly position the elongated body 17 on the support portion 15, an engagement mechanism 25 may be formed between the elongated body 17 and the support portion 15. In the preferred embodiment shown in the drawings, the engagement mechanism 25 includes a positioning projection 25a formed on the support portion 15 and a positioning groove 25b formed on the elongated body 17 for receiving the positioning projection 25 a. Of course, it is also possible that the positioning projection 25a is formed on the elongated body 17 and the positioning groove 25b is formed on the support portion 15.
Fig. 7 is a cross-sectional view similar to fig. 5, schematically illustrating the distribution of forces acting on the securing mechanism. As shown in figure 7, when the two strips 7 are pulled out and connected together, the free end of the first portion 9a of the clip 9 is subjected to an upward force F, and at least an obliquely upward force F1 reacts against the elongated body 17. As a result, there is no pulling force acting on the clip 9 in the oblique direction of the slot 11, so that the clip 9 does not come out of the slot 11. Preferably, the clip 9 further comprises a supported portion 9f projecting from the connecting portion 10 of the first and second portions 9a, 9 b. When the second portion 9b of the respective clip 9 is inserted into the elongate slot 11 and the two strips 7 are pulled out and connected together, the clip 9 can pivot on the supported portion 9f supported by the main body 14 of the housing 13 until the second portion 9b of the respective clip 9 abuts against the side wall of the elongate slot 11. When the supported portion 9f is supported by the main body 14 of the housing 13 of the spine coil unit 3, a downward force f2 acts against the housing 13. In this way, the obliquely upward force f1 can be reduced to prevent the second portion 9b from being damaged. Furthermore, the clip 9 further comprises a projection 9g extending from the bottom of the first portion 9a, and the elongated body 17 comprises an elongated receiving groove 17c for receiving the projection 9g extending from the bottom of the first portion 9 a. When the second portion 9b of the clip 9 is inserted into the elongate slot 11 and the free end of the first portion 9a of the clip 9 is subjected to an upward force F, another substantially horizontal force F3 acts against the elongate body 17, thereby further preventing the clip 9 from coming out of the slot 11. When the two strips 7 are in the inactive state and thus relaxed, the upward force F is released and the forces F1, F2 and F3 disappear. The clip 9 can be freely removed from the slot 11 by pulling the clip 9 upward in the oblique direction of the slot 11.
According to the present invention, the clip can be inserted into or released from the elongated slot at any position along the longitudinal direction of the spine coil unit. Therefore, the insertion and release of the clip is very convenient and easy for the operator.
Furthermore, in the above mentioned preferred embodiment, the elongated body 17 is a separate component made by injection moulding and assembled to the spine coil unit. The elongated body is easy to manufacture and quality control. Furthermore, even if the elongated body is damaged, the entire spine coil unit does not need to be replaced. Advantageously, the maintenance work only involves replacing the elongated body, which is cost effective and convenient. Of course, it should be understood that the elongate body may form part of, and thus be integrally formed with, the housing of the spine coil unit.
In the above-mentioned preferred embodiment, the slot for accommodating the clip is formed in the housing of the spine coil unit. It will be appreciated that the slot for receiving the clip may be formed within the housing of the countertop, for example, defined between the housing of the countertop and the elongate body supported by the housing of the countertop.
In the preferred embodiment mentioned above, the securing mechanism comprises two straps, each having a clip attached to one end thereof. It should be understood that the securing mechanism may include only one strap. In this case, the clip-free end of the strap can be pulled out and tied to the housing of the spine coil unit or to the table. Furthermore, the fixation mechanism according to the invention is not limited to fixing the flexible coil unit of the MRI system on the patient, it may also be used for fixing any object that is subsequently removed. In this case, the slot for receiving the clip may be formed at least in part by any suitable receiving member. In the present invention, the receiving member means a member used to define the elongated slot alone or define the elongated slot and the elongated body.
Although the invention has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred embodiments, it is to be understood that such detail is solely for that purpose and that the invention is not limited to the specifically disclosed embodiments, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims.
