The current technology would let us surpass operator dependence up to some important level but most manufacturers prefer to stick to known and proven technology rather than creating new things. The first is more profitable while the second involves expensive risks. IMHO, the only way we can honestly protect our patients is by doing our best at all times while being conscious of the technology limitations and ours as well. Please forward to me your opinion or any other information you might have available. As a medical electronic student, i would like to seek for your stand point of view regarding the phenomenon called speckle noise.
Speckle noise is an undesirable artifact that masks pathology.
It could be reduced using a phase insensitive technique, or a way to cancel the undesirable linear-phase representation. You could also consider adding a fuzzy logic algorithm. Be aware that if you do that, you are changing the image to meet your needs. The hardware requirements are difficult to meet now but if you use fuzzy logic algorithms, you could get outstanding results. Speckle phenomena are common when scanning fat patients.
