Table 1.

Study descriptions for parametric analyses involving a single-element (non-phased array) cylindrical transducer centered within a paraboloid balloon reflector, sonicating into a homogenous water medium. Varied parameter for each study is bolded.

Study #	Varied parameter	Transducer dimensions	Reflector dimensions**
1	Transducer length	Length: 10–20 mm OD: 10 mm	rG = 2 mm Length = 14–24 mm* ODMax adjusted accordingly (24.4–51.8 mm)
2	Transducer OD	OD: 4–10 mm Length: 10 mm	rG adjusted accordingly (2.6–8.4 mm) Length = 14 mm* ODMax = 35 mm
3	Transducer-reflector spacing (rG)	OD: 10 mm Length: 10 mm	rG = 0.5–10 mm Length = 14 mm* ODMax adjusted accordingly (22.3–49.8 mm)

^*Reflector length set to cover longitudinal extent of transducer length, plus 2 mm distal and proximal of transducer

^**Paraboloid geometric focal depth (L_F) swept from 5–100 mm for each study
