Hi everyone,i need some help.  
I want to correlate MPR with CPR,

when i click on the CPR view,the MPR view needs to jump to the corresponding image and move the crosshair to the corresponding position.

when i click on the MPR view,or move the crosshair,the CPR view also needs to change synchronously.

how can i do?  
thank you!
