CLINICAL EVIDENCE
Building Evidence for Longitudinal Cardiac Imaging
Sonologi is evaluating its wearable ultrasound and AI platform in clinical environments to understand its ability to capture and interpret cardiac information over time.
The company's clinical development strategy begins with high-acuity cardiac settings, where changes in patient condition can occur between conventional examinations.

EVIDENCE HIGHLIGHTS
EARLY CLINICAL FEASIBILITY
10+ ICU Patients
Early Testing in High-Acuity Care
Sonologi's wearable ultrasound technology has undergone early testing in more than 10 intensive care unit patients.
This work has been used to evaluate the feasibility of wearable cardiac imaging in a real clinical environment and to inform continued development of the device, imaging workflow and analysis platform.
Preliminary clinical and technical evaluation
AI MODEL DEVELOPMENT
5.6 mmHg
Reported Error in a Small Held-Out Cohort
In a held-out cohort of 47 patients, the model reported an error of 5.6 mmHg for the evaluated cardiac pressure-estimation task.
The cohort was small and consisted primarily of patients with HFrEF, defined in this study context as LVEF of 40% or below.
Requires larger, more diverse and prospective validation
VALIDATION QUESTIONS
What Sonologi Is Evaluating
Continuous cardiac ultrasound must demonstrate more than image capture alone. Sonologi is evaluating the technical, analytical and clinical questions required to support longitudinal imaging.
01
Wearability
Can cardiac ultrasound data be captured through a wearable system in real clinical settings?
02
Imaging Continuity
Can the platform maintain useful cardiac imaging information over an extended observation period?
03
AI Interpretation
Can AI identify measurements, patterns and trends within longitudinal ultrasound data?
04
Clinical Utility
Can longitudinal imaging provide clinicians with information that is not available from isolated examinations alone?
EARLY TESTING IN ICU PATIENTS
Evaluating Wearable Cardiac Imaging in a Real Clinical Environment
Sonologi's wearable ultrasound technology has undergone early testing in more than 10 intensive care unit patients.
This work has been used to evaluate the feasibility of wearable cardiac imaging in a real clinical environment and to inform the continued development of the device, imaging workflow and analysis platform.
These findings represent early-stage clinical and technical evaluation. They should not be interpreted as evidence of commercial availability, regulatory clearance or definitive clinical efficacy.

AI MODEL DEVELOPMENT
Exploring Cardiac Pressure Estimation from Ultrasound Imaging
5.6 mmHg reported error
Small held-out cohort, n=47
Early model development has explored whether ultrasound imaging information can be used to estimate clinically relevant cardiac measurements.
In a small held-out cohort of 47 patients, the model reported an error of 5.6 mmHg for the evaluated pressure-estimation task.
Important Context
The reported cohort was limited primarily to patients with heart failure with reduced ejection fraction, or HFrEF, defined in the study context as LVEF of 40% or below.
The result was obtained from a small held-out research cohort and requires validation in larger, more diverse and prospective patient populations.
INITIAL CLINICAL SETTINGS
Beginning Where Changes Can Be Difficult to Observe
Sonologi's early clinical strategy focuses on settings where patients face elevated risk and where intermittent assessments may leave important changes unobserved.
01
High-Acuity Care
Continuous or repeated imaging may provide additional visibility into cardiac changes in closely monitored patients.
02
Heart Failure Management
Longitudinal imaging may help clinicians understand how cardiac function changes during treatment, recovery and disease progression.
03
Post-Discharge Monitoring
The period after hospital discharge is a vulnerable time for many heart failure patients. Sonologi is exploring how continuous imaging could extend cardiac visibility beyond the hospital.
CLINICAL DEVELOPMENT PATH
A Staged Path from Platform Development to Clinical Use
Sonologi is advancing the platform through a staged development process that includes system refinement, clinical validation, regulatory preparation and future hospital deployment.
