摘要： Radiotherapy is one of the most effective treatments for cancer and its success depends critically on accurate targeting and delivery of the correct radiation dose. Accurate dosimetry is therefore essential to maintain and improve patient survival rates. However, size and long wait times currently limit water and graphite based calorimeters to standards laboratories leaving field-based dosimetry to ionization chamber measurements which depend upon a reference field-specified calibration factor. It would therefore be beneficial to provide radiotherapy equipment operators a direct approach of clinical reference dosimetry wherein the dosimeter provides increased independence on dose, dose rate, radiation energy, and energy type, etc. It would be further beneficial for such novel clinical dosimeters to be compact, function as secondary standards used routinely for measurements and allow radiotherapy doses to be measured directly and in an absolute manner. According to embodiments of the invention novel compact graphite probe calorimeters are provided.

摘要： Dispositif économique servant à la détection du radon, permettant de résoudre les problèmes posés par le bruit à court terme et par la dérive à long terme des composants. Le détecteur utilise une diode à semi-conducteur présentant une couche d'appauvrissement disposée à proximité d'un milieu de test, de sorte que des particules alpha déposent leur énergie dans la couche d'appauvrissement. Le signal produit par la diode est amplifié et on détecte les impulsions dont les niveaux dépassent un seuil typique des niveau des impulsions produites par la décroissance radioactive des produits de filiation du radon sur le capteur (20). Au moins deux canaux pourvus d'un amplificateur (32, 42) et d'un détecteur de seuil (50, 52) sont prévus, au moins un premier amplificateur (32) étant connecté au capteur (20) et un deuxième amplificateur (42) étant connecté à un capteur différent ou à une entrée fictive. Le deuxième amplificateur (42) et le détecteur de seuil (52) réagissent au bruit de la même façon que le premier amplificateur (32) et le détecteur de seuil (50), de manière à produire des impulsions sur les deux canaux lors de la survenance de perturbations transitoires, qui sont ignorées.
摘要翻译：用于氡检测的经济装置，解决了短期噪音和长期元件漂移的问题。该检测器使用具有设置在测试介质附近的耗尽层的半导体二极管，使得α粒子将其能量沉积在耗尽层中。由二极管产生的信号被放大，并且检测其电平超过由传感器（20）上的氡子体产物的放射性衰变产生的脉冲电平的阈值的脉冲。提供设置有一放大器（32，42）和一个阈值检测器（50，52）的至少两个通道，至少一个第一放大器（32）被连接到所述传感器（20）和第二放大器（42 ）连接到不同的传感器或虚拟输入。第二放大器（42）和阈值检测器（52）以与第一放大器（32）和阈值检测器（50）相同的方式对噪声作出反应，以便在瞬态干扰的发生，忽略。

摘要： Radiation therapy dose calculation methods, systems and computer program products, for use with a treatment delivery device for treating a patient and utilizing a scattered radiation detector in making independent dose calculations. The scattered radiation detector is configured to acquire measurement information during patient treatment, which is used to determine an estimate of the output of the treatment delivery device. Other information is acquired including patient imaging data, gantry angle information and collimator position information utilized during patient treatment. The acquired information is utilized along with the treatment delivery device output estimate to determine dose delivered to the patient.
