Description

用于磁共振成像系统的乳腺磁共振射频接收线圈 Breast MRI RF receiving coil for a magnetic resonance imaging system

技术领域 FIELD

[0001] 本发明涉及磁共振成像系统领域,具体涉及一种用于磁共振成像系统的乳腺磁共振射频接收线圈。 [0001] The present invention relates to the field of magnetic resonance imaging systems and more particularly relates to a magnetic resonance imaging system the magnetic resonance breast for receiving a radio frequency coil.

背景技术 Background technique

[0002] 磁共振成像(MRI)是继CT之后医学影像诊断技术的又一重大进展。 [0002] Magnetic resonance imaging (MRI) is another major progress after CT medical diagnostic imaging technology. 磁共振成像的基本原理来自于1946年美国学者Bloch和Purcell的发现,在外磁场的作用下,某些绕主磁场(外磁场)进动的自旋的质子(包括人体中的氢质子)在短暂的射频电波作用下,进动角增大;当射频电波停止后,那些质子又会逐渐恢复到原来的状态,并同时释放与激励波频率相同的射频信号,这一物理现象被称为核磁共振。 The basic principle of magnetic resonance imaging in 1946 from American scholar Bloch and Purcell found that under the effect of external magnetic field, some of the proton spins around the main magnetic field (magnetic field) precessing (including humans proton) brief under the effect of radio waves, the precession angle is increased; when the radio wave is stopped, those protons will gradually restored to the original state, and at the same time releasing the same frequency of the RF wave excitation signal, the physical phenomenon is known as nuclear magnetic resonance . 磁共振成像技术便是利用这一原理,通过在主磁场中附加一个脉冲梯度磁场,选择性地激发所需要位置的人体内的原子核,然后接收原子核产生的核磁共振信号,最后在计算机中进行傅立叶变换,对这些信号进行频率编码和相位编码,从而建立一幅完整的磁共振图像。 MRI is the use of this principle, by adding a gradient magnetic field pulse in the main magnetic field, to selectively excite nuclei of the human body required position, and then receives NMR signals generated in the nucleus, and finally in a computer performing a Fourier conversion, these signals phase encoding and frequency encoding, so as to establish a complete magnetic resonance image.

[0003] 磁共振成像装置包括射频发射线圈以及接收射频线圈,射频发射线圈用于产生脉冲梯度磁场,接收射频线圈用于接收原子核产生的核磁共振信号,接收射频线圈可以是发射线圈本身也可以是只接收射频信号的独立线圈。 [0003] The magnetic resonance imaging apparatus comprising a radio frequency transmission coil and the reception RF coil, the RF transmit coil for generating a magnetic field gradient pulse, receiving a radio frequency coil for receiving a nuclear magnetic resonance signal generated by the nuclei, the RF receiving coil may be a transmitting coil itself may be separate coils receive only a radio frequency signal. 在磁共振成像系统中,射频发射线圈所产生的磁场均匀性好以及接收线圈所接收的信号信噪比(SNR)高是获得高质量图像的关键因素。 In the magnetic resonance imaging system, the uniformity of the magnetic field generated by the RF transmit coil and a good signal to noise ratio (SNR) received by the receiving coil is a key factor in obtaining high quality images. 提高信噪比的方法有两种,一种为正交接收,另一种为相控阵线圈技术,后者使用多个独立的小线圈一起覆盖此区域,由于只有临近线圈的很小区域的噪声才能进入线圈,因此能够有效地提高信噪比。 There are two ways to improve the SNR of a quadrature receiver, and the other is a phased-array coil technology, which uses a plurality of independent small coil with coverage in this area, because only a small region near the coil noise to enter the coil, it is possible to effectively improve the SNR. 但是当射频发射线圈和接收射频线圈为同一线圈时,使用相控阵线圈会存在一个问题,即很难保证线圈所产生的磁场的均匀性,这个问题尤其体现在用于对人体各部位进行探测的磁共振成像仪上。 But when the RF transmit coil and the receiving RF coil is the same coil, using phased-array coil will be a problem that it is difficult to ensure the uniformity of the magnetic field generated by the coil, this problem is particularly reflected in the various parts of the human body for detecting a magnetic resonance imager. 由于人体各个生理部位的形状各不相同,又十分不规则,而且尺寸大小也差别很大,所以如何根据人体各个部位的生理结构特点,巧妙地布置线圈电路,从而获得较为均匀的磁场分布和较大的探测灵敏度一直是国际上线圈设计人员的最大任务。 Since the shape of the various parts of the body physiologically different, and is very irregular, and the size can vary greatly, so that the physical structure of how the characteristics of the various parts of the body, the coil circuit is arranged cleverly so as to obtain more uniform magnetic field distribution and more large detection sensitivity has been the biggest task coil international designers. 为了实现上述线圈设计目标,线圈外壳及内部机械结构的设计也成为保证高质量的扫描图像和满足生理结构覆盖范围的重要因素,精心设计的机械结构配合装配在其内部空间的天线电路共同实现了一个线圈设计中最重要的环节。 To achieve the design goals of the coil, the coil case and the internal design of the mechanical structure is also an important factor to ensure a high-quality scanned image and meet the physical structure of coverage, the mechanical structure designed to fit with the inner space of the antenna circuit to achieve a common a coil design is the most important part.

[0004] 随着磁共振检测技术的发展,乳腺癌等疾病筛查的重要性越来越受到重视,专门用于乳腺扫描的磁共振射频接收线圈的设计主要要求高信噪比、更大的覆盖范围,以及可以用于磁共振引导的活检取样的开放设计等。 [0004] As the importance of the development of MRI screening for disease detection techniques, such as breast cancer more and more attention, specifically for breast MRI scans of the RF receive coil is designed primarily for high signal to noise ratio, the greater the coverage, and an open biopsy sampling may be designed for guiding the magnetic resonance and the like. 目前用于乳腺扫描的磁共振射频接收线圈由于结构简陋,存在信噪比低、覆盖范围小、成像质量差的缺陷,制约了磁共振检测技术在乳腺癌等疾病筛查等领域的应用。 Currently MRI RF receiving coil for breast scanning due to simple structure, there is a low signal to noise ratio, small-coverage, poor image quality defects, which restricts the application of magnetic resonance detection technology in screening for diseases such as breast cancer and the like.
