Evaluation of internal MRI coils using ultimate intrinsic SNR.
The upper bounds of the signal-to-noise ratio (also known as the "ultimate intrinsic signal-to-noise ratio" (UISNR)) for internal and external coils were calculated. In the calculation, the body was modeled as a dielectric cylinder with a small coaxial cylindrical cavity in which internal coils could be placed. The calculated UISNR values can be used as reference solutions to evaluate the perfo...
متن کاملTheoretical prediction of parameter stability in quantitative BOLD MRI: dependence on SNR and sequence parameters
Introduction A static dephasing model [1] that analytically connects BOLD signal to hemodynamic parameters can be used to map the blood oxygenation level (Y) and venous cerebral blood volume (vCBV) in the brain. An extended version of this model was recently demonstrated with promising results in vivo [2], and has just been validated in a rat model [3] where the cerebral venous oxygenation was ...
متن کاملOptimization of Internal MRI Coils Using Ultimate Intrinsic SNR
Introduction Internal coils are widely used in MRI applications for both diagnostic and interventional studies [1]. Their high SNR characteristics make them more preferable in certain applications when compared to conventil external coils. Although many studies exist for the optimization of external coils to obtain increased SNR, an optimization study for internal MRI coils can also be made. In...
متن کاملIn vivo triple-quantum (TQ) sodium MRI on the human brain: SNR benefits at 7T
INTRODUCTION Triple quantum (TQ) sodium imaging is an effective means decreasing the contribution from the intracellular and fluid spaces to the sodium (Na) signal. This increased intra-cellular contrast is highly desirable for the study of pathologies such as cancer and stroke. The sodium TQ signal is, however, much weaker than the single quantum (SQ, or total tissue) signal (~1/10). It is, th...
متن کاملqfd planning with cost consideration in fuzzy environment
در عصر حاضر که رقابت بین سازمان ها بسیار گسترش یافته است، مطالعه و طرحریزی سیستم های تولیدی و خدماتی به منظور بهینه سازی عملکرد آنها اجتناب ناپذیر می باشد. بخش عمده ای از رقابت پذیری سازمان ها نتیجه رضایتمندی مشتریان آنها است. میزان موفقیت سازمان های امروزی به تلاش آنها در جهت شناسایی خواسته ها و نیازهای مشتریان و ارضای این نیازها بستگی دارد. از طرفی کوتاه کردن زمان ارائه محصول/خدمات به مشتریان...
