The limitations of the available input data and inherent problems with the calculation procedures make it very difficult to accurately determine the dose distributions in TBI. For these reasons, it is highly recommended to use In Vivo Dosimetry (IVD), to guarantee the quality of TBI treatments as a direct measurement of the delivered dose. An IVD QA system was implemented based on semiconductor diodes and radiochromic films. For the commissioning of the system, both detector types were calibrated independently, using as reference an ionization chamber with a valid certificate in terms of absorbed dose to water (Dw). This guarantees the traceability of the measurements. An experiment was carried out to simulate a clinical TBI procedure to a phantom. In this way, the calibration of the dosimetry system was confirmed.]]></p></abstract>

Por estos motivos, es altamente recomendable utilizar la dosimetría in vivo (IVD), para garantizar la calidad de los tratamientos de TBI como una medida directa de la dosis administrada. Se implementó un sistema IVD QA basado en diodos semiconductores y películas radiocromáticas. Para la puesta en marcha del sistema, ambos tipos de detectores se calibraron de forma independiente, utilizando como referencia una cámara de ionización con un certificado válido en términos de dosis absorbida en agua (Dw). Esto garantiza la trazabilidad de las mediciones. Se llevó a cabo un experimento para simular un procedimiento clínico de TBI a un fantasma. De esta forma, se confirmó la calibración del sistema de dosimetría.]]></p></abstract>
