Locating the patient accurately in real time is necessary for many medical robotics applications. Current solutions are expensive or inconvenient. We show progress toward solving these problems by using ultrasound to track computed tomography (CT) reference features in realtime. We compute the locations of target features in the ultrasonic images relative to the CT reference features.
The elimination of urban-rural differences in the Medicare prospective payment system (PPS) standard rates implies a need to re-examine all the PPS payment adjustments. Refinements for case mix, outliers, and the wage index can make a significant contribution to avoiding payment disparities in a single-rate system. However, changes in the adjustments for teaching and disproportionate-share (DSH) hospitals are also needed. The typically urban location of these hospitals makes it difficult to balance PPS payments and costs among major groups of urban and rural hospitals without some form of higher payment for all hospitals located in large urban areas.
