Most physiologists required a Ph - D degree and licensing. Before taking any exams required by their state, they should pass the Foreign Pharmacy Graduate Equivalency examination (FPGEE), Test of English as a Foreign Language (TOEFL) and Test of Spoken English (TSE) exams. An individual who finds work within this profession can certainly be a radiology technician if his competency qualifies him to execute work using x-ray, ultra-sound, CAT or ECG equipment that delivers the doctors with scanned images that the latter uses as bases for his or her diagnoses.
