Abstract: A method for Doppler scan conversion includes storing coded envelope values together with spectrum data in a memory out of a logic device with a large capacity, which increases the number of envelopes stored, reduces the use of the restricted embedded memory resources, and can also achieve the envelope switching more flexibly. If the number of envelopes is not greater than the difference between the bit width of the memory and that of the spectrum data, the increase in the number of envelopes will not increase significantly the logic resources or affect the efficiency of the system.
