Data clipping in radiology
WebNovel approaches to intracranial vascular imaging using monoenergetic reconstruction of dual-energy CT (DECT) and spectral data show promise to further reduce artifacts from aneurysm clips, but the evaluation of coiled aneurysm remains a challenge. 14,15 In addition, the significant initial capital cost associated with DECT means that, as a … WebJan 23, 2024 · For data cleaning, he has applied lowercase to all words and removed special tokens and eliminated words with numbers (like ‘hey199’, etc.). After extracting unique words he removed all those words whose frequency was less than 10 in the entire corpus so that model can be robust to outliers. Now he added “startseq” and “endseq” to ...
