International Congress of Bioengineering and Medical Physics
This Was the cause That led to Several research groups in the world looking for alternatives. One of the most promising is based on the use of optical fibers of small diameter (1mm), Which are fixed at one end a small piece of scintillator. A scintillator is a special type of material irradiated When That emits light, light the fiber Traveling Through To The Other end,where its can be measured intensity.
The value of the intensity of light to very specifying Provides Estimate of the rate of energy deposited in tissue and, Therefore, the damage done to cells. Because the optical fiber Can be used as a catheter, it is possible to make Measurements of the dose rate intracavitary radiotherapy During. Another important application is When the whole body is irradiated to Perform a bone marrow Then transplant. In this case it is possible to find the dose distribution by Calculation, as in-vivo Dosimeter and real time is of the UTMOST importance.
The technique of optical fiber is Dosimetry Studio by A Few research groups in the world. The most important are the Institute Risoe, Denmark, and the Royal Prince Alfred Hospital in Sydney, Australia. However, In recent years, doctors Caselli and Martin Eduardo Santiago, the “Institute of Physics Arroyo Seco” The only empezar to Investigate new types of scintillators for use in fiber optic Dosimetry. Through ITS work, Found That It Was That Several experimental compounds Studying the basic group Purposes, HAD properties much more commercial compounds Appropriate Than Commonly Used in this technique.
Part of the results of the research project were present at the Biomedical Engineering and Medical Physics World Congress 2009 (WC2009), the most important international congress of Bioengineering and Medical Physics Held in Munich, Germany. The group of Caselli and James has the support of the Cancer Center of the Sierras and the Sanatorium Tandil SA. In Both centers carry out experiments Aimed at luminescent Developing detectors. The group recently Obtained a new grant from the ANPCyT for Nearly half a million dollars to continue the project. This time, two bands will join to form a network of laboratories.
