Skeletal age of a child can be evaluated by MR images of
bones in the left hand. The hand imaging for young
subjects often suffers from motion artifacts. Shortening
the scan time provides an effective solution. Compressed
sensing (CS) is a promising technique, but an image is
not highly compressive when the signal-to-noise ratio (SNR)
is low, and the CS application to bone imaging using a
low-field MRI remains a challenge. Here we explore the
possibility of CS-based acceleration of bone imaging
with the 0.3T open compact pediatric hand scanner. We
further show the validity of CS-based skeletal
examination.
