| Abstract |
|
The purpose of this study was to develop
a solenoid coil for use with small animals in a 3
Tesla horizontal magnetic resonance imaging (MRI)
system, and to investigate image quality by
examination of parameters such as signal-to-noise
ratio (SNR) and Q-factor. A receiver solenoid coil
was formed by winding three separate coils of copper
tape around an acryl cylinder. The cylinder was
supported at each end. A euthanized rat weighing
240 g was used as a subject animal for imaging. A
cylindrical plastic tube containing a solution of
0.7 g/L CuSO4 was used as a phantom. Measured
SNRs were 985 in the phantom image 995 in the rat.
The Q-factor was 89 in the phantom and 84 in the
rat, in the loaded condition. The homogeneity of the
radiofrequency (RF) field was good and the resolution
of the image was sufficient to distinguish
internal organs from one another in the abdomen of
a rat. This study has demonstrated that a solenoid
coil may be used to produce good quality images of
small animals. |
