Abstract: A computer implemented method for providing cardiovascular images over a respiratory cycle through a computer system is provided. A plurality of cardiovascular images is obtained. A cardiac phase is measured for each cardiovascular image of the plurality of cardiovascular images to associate each cardiovascular image to a cardiac phase. A respiratory phase is measured for each cardiovascular image of the plurality of cardiovascular images to associate each cardiovascular image to a respiratory phase. A first group of cardiovascular images with an associated first cardiac phase of the plurality of cardiovascular images is sorted in order of respiratory phases. The first group of cardiovascular images with the associated first cardiac phase of the plurality of cardiovascular images is displayed in order of respiratory phases.

Abstract: Aspects of the present disclosure are directed to pressure sensing. As may be implemented in accordance with one or more embodiments, an external energy field is applied to a resonant circuit having inductive conductors separated by a compressible dielectric, for wirelessly detecting pressure. Specifically, the resonant circuit is responsive to the energy field and applied pressures by operating in respective states exhibiting different resonant frequencies that are based upon pressure-related compression of the compressible dielectric. These resonant frequencies, or a change in the resonant frequencies, can be used as an indication of the pressure.
