Towards robust deconvolution of low-dose perfusion CT: Sparse perfusion deconvolution using online dictionary learning
Computed tomography perfusion (CTP) is an important functional imaging modality in the evaluation of cerebrovascular diseases, particularly in acute stroke and vasospasm. However, the post-processed parametric maps of blood flow tend to be noisy, especially in low-dose CTP, due to the noisy contrast...
