Impact of Number of Repeated Scans on Model Observer Performance for a Low-contrast Detection Task in CT

Channelized Hotelling observer (CHO) has been validated against human observers for detection/classification tasks in clinical CT and shows encouraging correlations. However, the goodness of correlations depends on the number of repeated scans used in CHO to estimate the template and covariance matr...
