Typically, no, an ultrasound technician with just a PG diploma cannot independently open a clinic. While the diploma equips you with essential skills, it doesn't grant the legal authority to diagnose or interpret ultrasound images. In most places, this requires a medical degree and specialization in radiology.

However, you can explore opportunities as an ultrasound technician in diagnostic centers, hospitals, or clinics under the supervision of a qualified doctor. With experience and additional qualifications, you might consider starting a business providing ultrasound services, but always in collaboration with a medical practitioner.
