Johns Hopkins University, Baltimore, United States
Impact: The
proposed method enabled more robust APT imaging
quantification, which provides stronger APT signal intensity
values than traditional MTR asymmetry analysis. Preliminary
results proved its effectiveness in distinguishing treatment
effect and tumor recurrence and more applications are
expected.
