Implications of Dielectric Pads on Dual-Transmit SAR Behaviour
نویسندگان
چکیده
Purpose: Previous studies have shown a substantial reduction in local SAR when introducing dielectric pads in a quadrature driven body coil. One concern is that, when using dual-transmit B1 + shimming, the SAR estimate provided by the scanner could be incorrect since it is typically based on models that do not include the presence of dielectric pads [1]. This work explores the implications of using high permittivity dielectric pads on the SAR and B1 + shimming behaviour of a dual-transmit system at 3 T.

The effect of high-permittivity pads on specific absorption rate in radiofrequency-shimmed dual-transmit cardiovascular magnetic resonance at 3T
BACKGROUND Dual-channel transmit technology improves the image quality in cardiovascular magnetic resonance (CMR) at 3 T by reducing the degree of radiofrequency (RF) shading over the heart by using RF shimming. Further improvements in image quality have been shown on a dual-transmit system using high permittivity pads. The aim of this study is to investigate the transmit field (B 1 (+)) homoge...
متن کاملUniformity Using Segmented Dielectric Pads
INTRODUCTION: It has been shown that high-permittivity dielectric pads can be used to efficiently improve the field homogeneity in the region of interest (ROI) in high-field MRI [1-8]. Recent studies focused on the design of these pads by controlling parameters such as size, position and permittivity, using simple patient specific parameter sweeping to improve the transmit field in a small regi...
متن کاملReducing SAR and enhancing cerebral signal-to-noise ratio with high permittivity padding at 3 T.
Previous works have shown that placement of a high-dielectric pad can improve image intensity in a region adjacent to the pad, or that placement of dielectric pads around a large surface of the head can improve image homogeneity on an entire plane through the head in high-field MRI. Here, experimental results show that use of high-dielectric pads around the human head can reduce the required in...
متن کاملClinical applications of dual-channel transmit MRI: A review.
This article reviews the principle of dual-channel transmit MRI and highlights current clinical applications which are performed primarily at 3 Tesla. The main benefits of dual-channel transmit compared with single-transmit systems are the increased image contrast homogeneity and the decreased scanning time due to the more accurate local specific absorption ratio estimation, meaning that less c...
متن کاملIncreasing signal homogeneity and image quality in abdominal imaging at 3 T with very high permittivity materials.
The appearance of severe signal drop-outs in abdominal imaging at 3 T arises primarily from areas of very low B1+ transmit field in the body, and is problematic in both obese as well as very thin subjects. In this study, we show how thin patient-friendly pads containing new high permittivity materials can be designed and optimized, and when placed around the subject increase substantially the B...
