Visualization of multimodal polymer-shelled contrast agents using ultrasound contrast sequences: an experimental study in a tissue mimicking flow phantom

Table 2 Characteristics and settings of the contrast sequences

Ultrasound system	Contrast sequence	Transducer	Frequency (MHz)	Frame rate (Hz)	MI-range
Vivid7, GE	PI	M12L	5/10	32.7	0.2-1.2
Vivid7, GE	PI	M3S	1.5/3.1	25.7	0.2-0.8
iE33, Philips	PM	S5-1	1.5/3.2	39	0.2-1.2
iE33, Philips	PPI	S5-1	1.3/2.6	39	0.2-1.0
Acuson sequoia 512, Siemens	CPS	9 L4	4/8	17	0.2-1.0

PI = pulse inversion, PM = power modulation, PPI = power pulse inversion, CPS = contrast pulse subtraction, MI = mechanical index.
