Disclosed are systems, methods, and devices for interfacing with a wearable heads-up display via a finger-operable input device. The gamut mapping algorithm involves a lightness-rescaling step and a chroma compression step, in which points on each of the shells of the source GBD are mapped to corresponding points on the respective shells of the destination GBD. Specifically, in one embodiment of the present invention, an IVUS console is electrically connected to a computing device and adapted to acquire IVUS data. A self-aligned silicide process is carried out to form a self-aligned silicide layer over the exposed gate electrode and sourcedrain region.
