Fig. 6 schematically shows the support base of the breast imaging assembly of fig. 4, and fig. 7 shows the support base of the breast imaging assembly of fig. 4 in another schematic view. As shown in fig. 6 and 7, the support base 21 is formed of a foam or plastic material having rigidity and is substantially flat-shaped thinned from front to rear. The upper surface of the support base 21 constitutes a human body supporting surface 29, and the human body supporting surface 29 forms a curved surface inclined downward from front to back (in the direction from the head to the feet of the human body) at the rear. Two cavities 23 symmetrically formed by being recessed downward from the human body supporting surface 29 are provided in the front portion of the supporting seat 21. In the present application, the front portion of the support base 21 refers to a portion of the support base close to the head of the subject when the subject lies prone on the breast imaging module, and the rear portion of the support base refers to a portion of the support base away from the head of the subject or close to the feet of the subject when the subject lies prone on the breast imaging module. The cavity 23 is intended to receive, on the one hand, the flexible coil unit 25 and, on the other hand, the breast of the subject. The height of the first support seat portion 21a between the two cavities 23 is lower than the height of the second support seat portion 21b and the third support seat portion 21c immediately adjacent to the two cavities 23 on the rear sides of the two cavities 23, so that the first support seat portion 21a between the two cavities 23 constitutes a first support part for supporting the sternum of the subject. According to the present invention, a recess 21d is defined between the second support seat portion 21b adjacent to the two cavities 23 at the rear sides of the two cavities 23 and the third support seat portion 21c at the rear sides of the two cavities 23 and for supporting the right ribs of the examinee. The depth of the groove 21d is preferably between 15 and 20 mm. The body support surface portion constituted by the second support seat portion 21b and the third support seat portion 21c is formed substantially as a smooth surface having a slight curvature to better fit the body of the subject. In this way, when the subject lies prone on the breast imaging assembly 20, the sternum of the subject is supported by the first support seat portion 21a on the support seat 21, while the second support seat portion 21b forms a second support portion for supporting the left rib of the subject, and the third support seat portion 21c forms a third support portion for supporting the right rib of the subject, so that the entire human bone is supported at three portions constituting a triangle. As a result, the weight of the subject can be borne by the three scattered parts, so that the pain of the subject can be remarkably reduced and the comfort can be improved. The groove 21d defined between the second support seat portion 21b and the third support seat portion 21c is preferably splayed open in the rearward direction to conform to the distribution shape of the left and right ribs of the human body, thereby further improving the comfort of the examinee. Of course, it should be understood that the first support seat portion 21a may be disposed at substantially the same height as the second support seat portion 21b and the third support seat portion 21 c. However, in view of the fact that the sternum protrudes more outwardly relative to the ribs in the human bone, the first support seat portion 21a is preferably disposed lower than the second support seat portion 21b and the third support seat portion 21c in order to facilitate easier and reliable support at three locations when the subject lies prone on the breast imaging set.
In order to facilitate the placement of the flexible coil unit 25 on the support base 21, grooves 31 for receiving the wires of the flexible coil unit 25 are also formed on the support base 21, the grooves 31 being Y-shaped at portions near the two cavities 23 so as to open into the respective cavities 23. In the illustrated preferred embodiment, the Y-shaped portion of the groove 31 is recessed downward with respect to the bottom surface of the groove 21d between the second support seat portion 21b and the third support seat portion 21c to minimize discomfort that the lead wire of the flexible coil unit may cause to the subject.
Figure 8 shows schematically the coil unit housed in the support base of the breast imaging assembly shown in figures 6 and 7, but the flexible pad is not yet provided on the support base. Figure 9 is a schematic cross-sectional view of the breast imaging assembly shown in figure 4. As shown in fig. 8 and 9, the flexible coil unit 25 may comprise two coil unit halves 25a, 25b, which two coil unit halves 25a, 25b may be snapped together at the first support seat part 21a and attached to the first support seat part 21a by means of an adhesive material, such as velcro 33. In order to improve the flatness between the first support seat portion 21a and the recess 21d and thereby improve the comfort of the examinee, the height of the first support seat portion 21a is preferably selected such that the coil unit above the first support seat portion 21a is substantially flush with the bottom surface of the recess 21d after the two coil unit halves 25a, 25b are overlapped at the first support seat portion 21 a. The two cavities 23 symmetrically formed at the front of the support base 21 recessed downward from the human body supporting surface 29 are preferably open toward the side of the support base 21. In this way, the two coil unit halves 25a, 25b can be attached to the bottom surface of the respective cavity 23 by means of an adhesive material, such as velcro 33. At the same time, the opening of the two cavities 23 to the sides of the support base 21 also facilitates the turning up of the coil unit halves 25a, 25b to laterally approach or conform to the breast of the examinee until the coil unit halves 25a, 25b extend and cover the axilla region of the examinee. When necessary, the system also allows other medical operations, such as puncture operations, to be performed while scanning and imaging the examinee. This flip-up nature of the coil unit halves 25a, 25b also enables the breast imaging assembly 20 to be well suited for different examinees with different breast sizes. In order to ensure that the coil unit halves 25a, 25b approach or fit the breast of the examinee at the sides of the examinee's breast during the scanning imaging, a belt 35 may be provided on the coil unit halves 25a, 25b, respectively. The straps 35 provided on the coil unit halves 25a, 25b can be snapped together around the body of the examinee on the back of the examinee, for example, by velcro, as shown in fig. 10. The coil unit halves are attached to the support base on the bottom surfaces of the first support base portion 21a and the corresponding cavity 23 by attachment means such as velcro, and the two coil unit halves 25a, 25b are brought close to or fit against the breast of the examinee on the side of the examinee's breast by the belt 35 so that each coil unit half assumes a substantially V-shape during the scanning imaging, and as a result, the examinee's breast can be kept in a substantially natural sagging state during the scanning imaging, and the breast tissue is not significantly compressed, thereby contributing to improvement in breast imaging quality and improvement in the examinee's comfort.
In order to make it possible to visually confirm whether the coil unit halves 25a, 25b and the breast of the examinee are held in proper condition when the coil unit halves 25a, 25b are placed on the examinee's body, windows 37, each of which penetrates the corresponding cavity 23, are provided on the front side of the support base 21. If the operator finds through the window 37 that the coil unit halves 25a, 25b and/or the breast of the examinee are not kept in a proper state, adjustments may be made to the coil unit halves 25a, 25b and/or the examinee's body to ensure that the coil unit halves 25a, 25b and/or the examinee's breast are kept in a desired proper state, thereby contributing to better imaging quality. To facilitate the carrying of the breast imaging assembly 20, a gripping portion 39 may be further provided on each side of the support base 21. The grasping portions 39 may be notches formed on both sides of the support base 21 as shown in the drawing, or may be handles formed on both sides of the support base 21.
After the coil unit halves 25a, 25b have been set on the support base 21 as shown in fig. 8, the flexible mat 27 is laid on the support base 21. To facilitate the laying of the flexible mat 27 on the support base 21 and to prevent displacement of the flexible mat 27, the flexible mat 27 has a shape matching the contour of the body support surface 29 of the support base 21.
As described above, when the examinee lies on the breast imaging module according to the present invention, the weight of the examinee is borne by the three scattered portions at the vertices of the triangle, rather than by one line contact portion, which significantly reduces the pain of the examinee, thereby improving the comfort of the examinee.
While the invention has been described in detail in connection with the preferred embodiments thereof, it is to be understood that such detail is solely for that purpose and that no limitation of the invention is thereby intended. The scope of the present invention is defined by the claims.
