Measurement navigation in a multi-modality medical imaging system

An apparatus, comprising:

• an intravascular catheter or guidewire comprising at least one of a pressure sensor or a flow sensor;
• and
• a processor configured for communication with the intravascular catheter or guidewire, wherein the processor is configured to:
• receive medical data obtained by the intravascular catheter or guidewire while the intravascular catheter or guidewire is positioned within a vessel of a patient, wherein the medical data comprises at least one of pressure data obtained by the pressure sensor or flow data obtained by the flow sensor;
• output, to a display in communication with the processor, a first graphical representation of the medical data, wherein the first graphical representation comprises a waveform of the medical data;
• receive, from an input device, a selection of a region of the waveform associated with a subset of the medical data;
• in response to the selection of the region, automatically perform an enhancement of the subset of the medical data to generate a second graphical representation, wherein the enhancement comprises a resealing of the region of the waveform such that the second graphical representation comprises only the region of the waveform that has been resealed;
• and
• output, to the display, the second graphical representation.
