SQL Server 2008: Measure tps / select statements per second for a specific table?

Question

There is a discussion how to measure activity against an entire DB: https://stackoverflow.com/questions/5019593/sql-server-2008-transaction-per-second-for-specific-database

My question is narrower.

We are working on performance optimization of our application. To see how we are doing, we need to measure SELECT operations per second/minute/hour (prefer hour) on a specific table. (This way we can measure before and after implementing the optimization, to see how we are doing.)

What is the method or tool to do this?

Thank you!
