摘要： A 3D camera system (10) for a patient positioning and monitoring system is described. In the system a pair of image detectors (50) are provided where the image detectors (50) are each associated with a heater (64) thermally connected to conducting pads (68) provided at the periphery of the image detectors (50). The heaters (64) and conducting pads (68) act to contain the image detectors (50) in a substantially constant temperature micro climate thereby preventing external temperature variations from causing the relative positions of the image detectors to change so as to record portions of images as different pixels and hence reduce the consistency with which the identification of matching portions of images obtained by the image detectors (50) can be utilized to determine the 3D positions of imaged objects.

摘要： A method of calibration of a stereoscopic camera system (10,12) for use with a radio therapy treatment apparatus(14) is provided. Initially a calibration phantom (18) is positioned on an adjustable table (20) on the surface of a mechanical couch (16) with the phantom's centre at an estimated location for the iso-centre of a radio therapy treatment apparatus (14). The calibration phantom (18) is then irradiating using the radio therapy treatment apparatus (14) and the relative location of the centre of the calibration phantom and the iso-centre of the radio therapy treatment is determined by analysing images of the irradiation of the calibration phantom (18). The calibration phantom (18) is then repositioned by the mechanical couch (16) applying an offset corresponding to the determined relative location of the centre of the calibration phantom and the iso-centre of the radio therapy treatment apparatus (14) to the calibration phantom (18). The stereoscopic camera system (10,12) then proceeds to obtain images of the relocated calibration phantom (18) to which the offset has been applied and processes the obtained images to set the co-ordinate system of the stereoscopic camera system (10,12) relative to the iso-centre of the radio therapy treatment apparatus (14).

摘要： A method of assisting a patient (24) in controlling their position is disclosed. Reference position data (RP) indicative of a reference position of a patient is obtained. Actual position data (AT) is monitored and compared with the reference position data (RT) to determine a position deviation, and the intensity and/or brightness and/or hue angle and/or flicker rate of emitted light which is detectable by the patient as ambient light is changed if there is a position deviation.

摘要： Images obtained by a camera system (10) arranged to obtain stereoscopic images of a patient (20) undergoing radio-therapy are processed by a modeling unit (56,58) which generates a model of the surface of a patient (20) being monitored. Additionally the patient monitoring system processes image data not utilized to generate a model of the surface of a patient being monitored to determine further information concerning the treatment of the patient(20). Such additional data can comprise data identifying the relative location of the patient and a treatment apparatus (16). This can be facilitated by providing a number or retro-reflective markers (30-40) on a treatment apparatus (16) and a mechanical couch (18) used to position the patient (20) relative to the treatment apparatus (16) and monitoring the presence and location of the markers in the portions of the images obtained by the stereoscopic camera (10).
摘要翻译：通过布置成获得经历放射治疗的患者（20）的立体图像的相机系统（10）获得的图像由建模单元（56,58）处理，该建模单元生成被监视的患者（20）的表面的模型。另外，患者监视系统处理未被用于产生被监视患者的表面的模型的图像数据，以确定关于患者（20）的治疗的进一步的信息。这样的附加数据可以包括识别患者和治疗装置（16）的相对位置的数据。这可以通过在治疗设备（16）和用于将患者（20）相对于治疗设备（16）定位和监测的机械床（18）上提供数量或后向反射标记（30-40）而得到促进在由立体照相机（10）获得的图像的部分中的标记的存在和位置。
