Adelaide de Almeida
Dr. Adelaide de Almeida is an associate professor of physics at the Universidade de São Paulo in Brazil. Her work includes the study of ionizing radiation including theory, practice, and simulation areas on interest, radiotherapy treatment planning using nodesenvolvimento techniques and protocols, methods and measuring protocols for dosimetry of ionizing radiation, and the quality control of sources of radiation and equipment used in dosimetry in the instrumentation development to control dose and radiation sources. Dr. de Almeida’s research also studies the techniques and image optimization in fossil dating using radiological methods and materials and in working with other physical techniques that use common ionizing radiation.
Much of her work has focused on dosimetry, which in medial physics is the calculation and assessment of the radiation doses received by the human body. When exposure to radioactive materials has taken place internally doctors rely on physiological or imaging techniques to measure the exposure while irradiation from external sources can be measured using a dosimeter. Medical dosimetry, one of de Almeida’s specialties, is the monitoring of the collateral absorbed dose of radiation when used in medical treatments.
Earning her Master’s Degree in Physics from the Universidade de São Paulo in 1983, de Almeida’s thesis focused on investigations with dosimeter cylindrical electret for fast neutrons. In 1990 she was awarded a doctorate in physics from the same university with her research focus being quantum noise influence on radiological images. When x-rays are created to be used for medical imaging there is a natural random variation that leads to what is called quantum noise and she has continued to study this phenomena.
As a postdoctoral researcher she spent a year working at the Università di Roma La Sapienza in Italy and a year at the University of Alabama at Birmingham in the United States. Since 1989 she has been a member of the faculty at Universidade de São Paulo teaching various courses including medical physics, chemistry, radiotherapy and electricity and magnetism. Dr. de Almeida has written over fifty full articles that have been published in scholarly journals and has presented at numerous international conferences.
