The purpose of this clinical trial is to verify the safety and effectiveness of the remote automatic ultrasound diagnosis system produced by Wuhan Cooper Technology Co., Ltd. for automatic ultrasound examination. It aims to answer the main questions:

Can the robot complete automatic ultrasound scanning of multiple systems and organs such as liver, gallbladder, spleen, pancreas, kidney, thyroid, carotid artery, etc.? Will there be medical safety issues during the robot's scanning process?

Inclusion Criteria:

• 1) Aged ≥ 18 years old, regardless of gender; 2) Those who need to undergo ultrasound examination; 3) Those who voluntarily participate in this trial and sign the informed consent form.

Exclusion Criteria:

• 1) Those who are allergic to ultrasound coupling agents; 2) Those who are unable to undergo long-term ultrasound examinations due to physical or mental reasons (such as intellectual disability, mental illness, etc.); 3) Those who have suffered severe trauma or burns within the past month; 4) Pregnant or breastfeeding women; 5) Those who have participated in other clinical trials within the past month; 6) Other subjects deemed by the researchers to be unsuitable for participating in the trial.

This study will recruit adults over 18 years old, especially those who need multi-organ ultrasound examinations. Participants need to be able to understand and sign the informed consent. We hope to include patients of different ages, genders, and health conditions to ensure the wide applicability of the study results. Your participation will help us test and improve the autonomous ultrasound robot so that it can work effectively in a variety of populations.
