We studied the efficiency of transferring task information from each stage of the ultrasonic imaging to another by computing the total task energy available at each stage. We computed the task-energy efficiency for the B-mode data with respect to RF data as an expression to predict performance efficiency. We also measured performance efficiency of B-mode image observers with that of ideal observer of the RF data using both analytical SNR expressinos and Monte-Carlo expreriment over a range of visual tasks related to breast lesion diagnosis. The performance efficiency results are compared with the prediction from task-energy efficiency and information efficiency. It is shown that task-energy efficiency can closely predict the performance efficiency especially for large-area tasks.
