Abstract: A system for MR signal excitation and reception and method which uses a non-resonant device or transmission line to perform MR imaging and spectroscopy. The system with non-resonant device is advantageous to parallel imaging due to the improved decoupling performance. Because the non-resonant RF coil is not generally sensitive to frequency, a MR system with the non-resonant RF coil is capable of multinuclear MR operation at varied magnetic field strength. The system comprises a non-resonant RF coil for connecting to an MR system, the conductor being configured to have a characteristic impedance matched to the MR system. The RF coil is configured to produce electromagnetic fields of differing strengths based on the constant characteristic impedance maintained in the system for exciting and receiving MR signals.

Abstract: Apparatus and method for MRI imaging using a coil constructed of microstrip transmission line (MTL coil) are disclosed. In one method, a target is positioned to be imaged within the field of a main magnetic field of a magnet resonance imaging (MRI) system, a MTL coil is positioned proximate the target, and a MRI image is obtained using the main magnet and the MTL coil. In another embodiment, the MRI coil is used for spectroscopy. MRI imaging and spectroscopy coils are formed using microstrip transmission line. These MTL coils have the advantageous property of good performance while occupying a relatively small space, thus allowing MTL coils to be used inside restricted areas more easily than some other prior art coils. In addition, the MTL coils are relatively simple to construct of inexpensive components and thus relatively inexpensive compared to other designs. Further, the MTL coils of the present invention can be readily formed in a wide variety of coil configurations, and used in a wide variety of ways. Further, while the MTL coils of the present invention work well at high field strengths and frequencies, they also work at low frequencies and in low field strengths as well.

Abstract: The invention discloses a quick tee joint component and a drilling jig component specially for drilling. For installation of a quick tee joint, a drilling jig for quick tee joint is firstly installed on a pipe where a branch pipe is to be added. A bushing of the drilling jig is in threaded connection with the drilling jig, to achieve convenient replacement, and is made of a high-hardness metal material. Under the limiting action of the bushing, the position of a reamer is ensured not to deviate during the reaming process, thereby ensuring the reaming quality. The requirement for different sizes of holes drilled by the drilling jig can be met by simply changing the size of the bushing of the drilling jig. Once reaming is done, fastening bolts are unscrewed so as to remove the drilling jig and a quick tee joint body is installed. A lengthening part of the quick tee joint body guarantees the installation position accuracy of the quick tee joint. In case of vertical installation of the quick tee joint, a notch in the lengthening part allows accumulated liquid to flow out to prevent the fluid from accumulating at the lowest point of the pipe for long time and affecting the working efficiency, thereby avoiding corrosion and extending the service life of the pipe.
