1. A method for medical imaging executed by an apparatus comprising a processor, the method comprising:

  • determining a start block of volume rendering based on respective maximum values of blocks positioned on a path of a light beam;

    acquiring a value of the light beam based on first sampling values acquired by sampling the start block;

    setting a processing order for remaining blocks positioned on the path of the light beam based on respective distances between the start block and the remaining blocks;

    determining whether a next block is to be processed, by comparing a maximum value of the next block with the value of the light beam, according to the set processing order; and

    comparing second sampling values acquired by sampling the next block with the value of the light beam and updating the value of the light beam according to a comparison result, in response to the maximum value of the next block being greater than the value of the light beam.
