Claim 7:
8. The method as defined in claim 7, wherein a) said dense particle additive has a density of at least 1.7 g/cc and constitutes about 0.001-30 wt. % of said outer coating and is added in sufficient quantities to said outer coating to increase a density of said acoustic imaging particles by 0.5-5 g/cc, b) said reinforcing agent constitutes about 0.001-10 wt. % of said outer coating, said reinforcing agent increasing said crush strength of said acoustic imaging particles by 10-2000%, and c) said degrading agent constitutes about 0.001-10 wt. % of said outer coating, said degrading agent reducing a time of degradation of said outer coating by at least 5%.
