As a beginner, a diagnostic medical sonographer can make about $17 an hour, which totals to $40,000 a year. Experienced doctors can make around $90,000 a year. The hard part about this job is that one needs to have about 10 to 15 years of experience to make a real difference in the annual salary. The salary of the professional is mostly influenced by the medical facility where he or she is working. Some private clinics can pay their doctors more than $100,000 a year.
