Visual aids in teaching are recognized as important adjuncts to proper training of medical and dental students and physicians. In the field of radiation therapy, since radiation beams are invisible by ordinary methods and potentially harmful to observers where they can be shown, the use of a translucent anatomic model with a light beam to simulate the central ray of the x-ray therapy beam is of value for teaching accuracy in directing the radiation beams. Students, residents, and physicians in all fields of medicine, particularly in radiation therapy, can appreciate the importance of proper placement and aiming of the beam of irradiation. Especially where small treatment fields are being used, slight variations in the proper angulation may only partially cover an area to be treated, resulting in inadequate dosage to the tumor being treated. This can be readily visualized with the beam directed into the translucent model.1An anatomic |
