Vascular diagnositc apparatus and method

A vascular diagnosis system, comprising

• at least one processor, the at least one processor configured to:
• obtain angiogram data of a patient's vascular system, said angiogram data comprising a field of view of a patient's vascular system;
• process the angiogram data to generate a semantic angiogram data comprising information on the presence and position of anatomical features present in the field of view;
• process the semantic angiogram data to determine one or more velocity curves according to one or more locations, wherein a velocity curve comprises data of blood velocity against time for a specific location in the field of view;
• determine one or more characteristics from the one or more velocity curves according to the one or more locations;
• generate diagnostic data corresponding to the one or more locations, from the one or more characteristics and the semantic angiogram data;
• and
• generate a composite view comprising the diagnostic data.
