Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Alternative format of non-invasive diagnostic procedure - cardiac ultrasound

Procedure - Utilisation of existing clinically used cardiac ultrasound systems where system probe is held by robotic arm. Sonographer utilises a gamepad to control the robotic arm system to acquire images.

Any ultrasound system is permitted, and a specific vendor is utilised based on the discretion of the hospital.

Sonographers will undergo a minimum of 15 hrs of virtual (software-based only) and hand-on simulator training, prior to human scanning.

Standard operation manuals are provided to ensure correct and standardised use of the system.

All participants will receive both procedures immediately after each other (consenting staff participants), or within 72hrs of each other (consenting patient participants); with the robotic arm used first and the manual probe used second (consenting staff participants), or the robotic arm used second after manual probe examination (performed for clinical purposes; sonographer blinded to the clinical exam)
Intervention code [1] 326203 0
Diagnosis / Prognosis
Comparator / control treatment
Traditional image acquisition method - Manipulation of probe by hand to acquire images.

All aspects of this procedure will be the same as those using the probe held by the robotic arm, including; the number and types of images acquired, and number and types of assessments performed.
Control group
Active

Outcomes
Primary outcome [1] 334904 0
Feasibility of novel ultrasound method - Robot manipulation of probe to acquire images (intervention)

Feasibility will be assessed based on ability to obtain both sufficient and valid images to perform each of the 10 major assessments of cardiac structure and function, and similar with the 37 individual measurements within.
Timepoint [1] 334904 0
Assessment of primary outcome occurs during examination session - intervention and control procedure performed back to back respectively.
Primary outcome [2] 335090 0
Accuracy of novel ultrasound method - Measurements on acquired images - Robot manipulation of probe to acquire images (intervention)

Accuracy will be assessed based on ability to obtain sufficient and valid measures from both sufficient and valid images to perform the 37 individual measurements comprising structure and function.
Timepoint [2] 335090 0
Assessment of primary outcome occurs during examination session - intervention and control procedure performed back to back respectively.
Secondary outcome [1] 422380 0
Assessment of efficiency of intervention - Time taken to perform all image acquisitions comprising a standard cardiac ultrasound examination (based on time between first and last image capture)
Timepoint [1] 422380 0
Assessment of secondary outcome occurs during examination session - intervention and control procedure performed back to back respectively.
