A host system (100) comprising a graphical user interface and further comprises a processing system having first and second modular measurement processing components； where the host system is configured to control the operation of a first invasive cardiovascular detection component to cause the first invasive cardiovascular detection component to obtain data related to the measurement of a first invasive cardiovascular parameter； where the host system is further configured to control the operation of a second invasive cardiovascular detection component to cause the second invasive cardiovascular detection component to obtain data related to the measurement of a second invasive cardiovascular parameter, the second invasive cardiovascular parameter being different from the first invasive cardiovascular parameter； where the first modular measurement processing component is configured to process data obtained from the first invasive cardiovascular detection component to produce a first set of values associated with the first invasive cardiovascular parameter for display in the graphical user interface； where the second modular measurement processing components is separated from the first modular measurement processing component and is configured to process the data obtained from the second invasive cardiovascular detection component to produce a second set of values associated with the second invasive cardiovascular parameter for display in the graphical user interface； where at least a portion of at least one of the first set of values and the second set of values is shown in the graphical user interface； and where the first invasive cardiovascular parameter is a pressure inside a vessel and where the second component of invasive cardiovascular detection is configured to obtain images of the vessel in cross-section based on light.Un sistema (100) huésped que comprende una interfaz de usuario gráfica y comprende además un sistema de procesamiento que tiene primeros y se
