         34 . The method of  claim 31 , further comprising:
 updating the displayed information as the location on the touchscreen is modified.   
     
     
         35 . The method of  claim 31 , further comprising:
 forming a pin at the location, the pin being movable within the model by a user; and   updating, on the touchscreen, the information regarding the blood flow characteristic in the patient's vasculature as the pin is moved by the user.   
     
     
         36 . The method of  claim 31 , further comprising:
 determining the information regarding the blood flow characteristic in the patient's vasculature at a plurality of locations in the three-dimensional model and indicating the information on the displayed three-dimensional model using at least one of shading, patterns, or coloring.   
     
     
         37 . The method of  claim 31 , further comprising:
 rotating the displayed three-dimensional model in response to the user swiping a surface of the touchscreen, an amount and direction of rotation depending on a characteristic of the swipe.   
     
     
         38 . The method of  claim 31 , further comprising:
 adjusting a zoom on the displayed three-dimensional model in response to the user pinching two of a plurality of pointing objects located at separate locations with respect to the touchscreen, an amount of the zoom depending on a characteristic of the pinch.   
     
     
         39 . The method of  claim 31 , wherein the processor is configured to display a stent as the intervention. 
     
     
         40 . The method of  claim 39 , further comprising:
 receiving an input indicating a size of the stent or a change in location or change in size of the stent.   
     
     
         41 . The method of  claim 39 , further comprising:
 providing a split screen including a first portion and a second portion, the first portion displaying the three-dimensional model representing at least the portion of the patient's vasculature and the stent, and the second portion displaying the three-dimensional model after placement of the stent.   
     
     
         42 . The method of  claim 31 , wherein the processor is further configured to display a bypass as the intervention. 
     
     
         43 . The method of  claim 42 , further comprising:
 receiving an input indicating at least one location for connecting the bypass to the displayed three-dimensional model, and an input indicating a change in location or a change in size of the bypass.   
     
     
         44 . The method of  claim 31 , further comprising:
 providing a split screen including a first portion and a second portion, the two portions being configured to receive different inputs indicating different modifications of respective displayed three-dimensional models.   
     
     
         45 . The method of  claim 31 , wherein receiving the input includes receiving the input from at least one pointing object controlled by the user, and the at least one pointing object includes at least one digit of the user or a stylus. 
     
     
         46 . The method of  claim 31 , wherein the information includes at least one of pressure gradient, pressure, flow rate, and velocity.
