Abstract: Background　Both ultrasound imaging and general medicine are developing rapidly. But it is still unknown that whether the advancement and popularization of portable ultrasound imaging can be used by general practitioners（GPs） to promote the development of general medicine，and what innovative ideas and methods can be used to accelerate the popularization of ultrasound imaging in primary care and to train ultrasound professionals with humanistic care，early disease screening，high service accessibility，and medical insurance expense control in primary care under consideration. Objective　To explore the perspectives of multiple healthcare providers（community GPs，community sonographers，and general hospital sonographers） on GPs' learning ultrasound techniques and applying portable ultrasound devices，and their suggestions on the implementation goals and specific operation requirements. Methods　The study was implemented from October to December 2019. In-person interviews using a semi-structured format were conducted with GPs and sonographers from Pudong New Area Jinyang Community Health Center，a community hospital that has trained the most GPs in China so far in terms of ultrasound learning and practice（two authors' current affiliation） for investigating their attitude and willingness regarding learning ultrasound techniques and delivering ultrasound services，and their opinions on the required ultrasound knowledge and level of actual performance. And two rounds of consultation using the Delphi technique were carried out with 17 sonographers with an experience of working at least 10 years in the general hospital for investigating their opinions on the specific requirements for community GPs to perform the ultrasound examination，such as collecting，storing and transmitting ultrasound imaging data，and making an ultrasound-based diagnosis. Results　Altogether，six community GPs and three community sonographers attended the interviews. The results showed that community GPs had interests in learning ultrasound techniques，and expressed their concerns about the post-learning application. Community sonographers believed that trained GPs would be capable of performing ultrasound examinations，and they could begin from performing simple scanning of external organs，such as thyroid and carotid. The positive and authoritative coefficients of senior sonographers for the two rounds of consultation were all 100.0%，and greater than 0.7，respectively. The consultation results indicated that eligible community GPs for collecting data of ultrasound examinations should have: a bachelor degree or above，major in clinical medicine，at least three years' clinical practice，GP certification，ultrasound technician certification，and at least two times of attending continuing ultrasound education per year. The required levels of knowledge and skills for GPs to store and transmit ultrasound imaging data，and make an ultrasound-based diagnosis were almost the same for sonographers，including common instrument adjustment，postural guidance，operation techniques，plane choice，probe placement，knowledge of data should be recorded，stored and reported，and knowledge of common requirements for diagnostic classification. Conclusion　Community GPs showed interests in learning ultrasound techniques for increasing their competencies，and they could try to begin from performing scanning of thyroid and carotid. The operational procedures and actual settings appropriate for GPs to perform ultrasound examinations should be determined. The use of portable ultrasound device may be a key to benefiting the ultrasound performance of GPs，which can be used to scan thyroid，carotid and other organs with a clear shape and simple structure，and to screen for chronic diseases as a chronic disease management program vigorously promoted in the community.
