Ranking scheme for subjective tissue integration quantification of ultrasound images

Subjective ranking key
0	Implant not visible
1	Implant barely visible (roughly 25% or less of margin visible)
2	Implant visible but margins are not well demarcated from adjacent tissue (roughly between 25-50% of margin visible)
3	Implant visible but margins not consistently demarcated from adjacent tissue (roughly between 50-75% of margin visible)
4	Implant is obvious with margins clearly demarcated (roughly between 75-100% of margin visible)
5	Implant extremely obvious with clearly defined margins
