摘要： A magnetic resonance (MR) system may include: a volume-type radio-frequency (RF) coil assembly having a volume coil with a plurality of ports and a ring coil with a plurality of ports (ρ′) and which is situated about the volume-type coil; and at least one controller configured to selectively control a first transmit/receive (T/R) radio frequency (RF) channel to generate an output including RF quadrature signals to drive the volume-type coil and to selectively control a second T/R RF channel to generate an output including RF quadrature signals to drive the ring coil.

摘要： Coil elements (18) generate a B1 excitation field in an examination region (14), which B1 excitation field is distorted by patient loading (e.g., wavelength effects). Passive shimming elements (22, 24) are disposed between the coil elements and the subject in order to improve the B1 field uniformity. In one embodiment, passive shimming elements include one or more dielectric rods (55) disposed below the subject which generate no substantial MR proton signal and which have a permittivity of at least 100 and preferably greater than 500. In another embodiment, tubes (24) adjacent each coil element are supplied with a dielectric liquid, a thickness of the dielectric liquid between the coil element and the subject adjusting a phase of the B1 field generated by the coil element. Active B1 shimming may be combined with passive shimming elements (22, 24) to effect an improved RF field homogeneity result.

摘要： A radiation therapy planning and follow-up system(10) includes an MR scanner (12) with a first bore (16) which defines an MR imaging region (18)and a functional scanner (26), e.g.,a nuclear imaging scanner,or a CT scanner with a second bore (30) which defines a nuclear or CT imaging region (36). The first and second bores (16,30) have a diameter of at least 70cm, and preferably 80-85 cm. A radiation therapy type couch (90) moves linearly through the MR imaging region (18) along an MR longitudinal axis and the nuclear or CT imaging region (36) along a nuclear or CT longitudinal axis which is aligned with the MR longitudinal axis. The couch positions a subject sequentially in the MR and nuclear or CT imaging regions (18, 36). A fusion processor combines an image representation generated from data collection in the MR imaging region (18) and an image representation generated from data collection in the nuclear or CT imaging region (36) into a composite image representation and a planning processor (112) generates a radiation therapy treatment plan according to the composite image.
