Founded on April 3, 1982, ISUM (PUSKI) is an autonomous medical organization with the Indonesian Medical Association (IDI) as its parent. ISUM serves as an umbrella organization for medical practitioners from various disciplines who frequently use USG (Ultrasonography) instruments to provide medical services, such as radiologists, obsteric-gynecologists, internists, cardiologists, pediatrists, and general practitioners.

This organization aims to improve the quality of healthcare in Indonesia and to develop a group of qualified sonologists and other healthcare professionals. For the purpose of achieving the above, since 1996 ISUM has been running an USG Education and Training Program at the Basic, Intermediate, and Advanced levels.
