Data Collection for Next Generation Ultrasound Technology Development

The study is designed to collect data from a ultrasound device being used to evaluate
feasibility of next generation algorithms for ultrasound data processing and does not test
any health outcome. All eligible adults (aged 18 or older) will contribute case data from a
convenience sample of maintenance hemodialysis population available at the study site and
consistent with feasibility assessment of the technology. A relatively large feasibility
population is used due to the need to test feasibility of multiple features across variations
within this population.

Inclusion Criteria:

1. Are adults (aged 18 years of age or older) at the time of consent;

2. Are undergoing maintenance hemodialysis (MHD); AND

3. Are able and willing to provide written informed consent for participation

Exclusion Criteria:

1. Have anatomical characteristics or comorbid medical conditions that prevent completion
of ultrasound scanning using the study device; OR

2. Are potentially put at additional risk by participating, in the opinion of the
investigator.
