dc.description.abstractAny good medical ultrasound imaging system must be able to resolve anatomical structures properly, and simultaneously provide adequate frame rate so that moving structures can be studied with ease. In a conventional imaging system these properties are related by a trade-off, but is it possible to have one and the other by applying more advanced post-processing to acquired RF data? Two new methods, beam RF interpolation (BRI) and beam delay interpolation (BDI), are presented to solve this trade-off issue, using the SURF imaging technique to improve contrast resolution, and the new methods to increase frame rate. \emph{In vitro} data was acquired using a standard imaging phantom, and a modified SURF imaging system, and processing of the data was done off-line. The results show that the new methods have potential to contribute to increasing frame rate and contrast resolution, but hardware issues necessitate verification of the results using different equipment.nb_NO
