    • The invention relates to a method for optically scanning the three-dimensional geometry of an object by means of triangulation, in which a pattern (9, 9') is projected onto the object (7) to be scanned in order to obtain a 3D data set, and the projected pattern (9, 9') is recorded in an image (40, 41). In a first step for the production of at least one first image (40), a first pattern (9) is projected and in a second step for the creation of at least one further image (40), a further pattern (9') deviating from the first as regards position or shape is projected onto the object (7) to be scanned and the image (41) is created. The first image (40) and the further image (41) comprise at least one common point (44). The 3D data acquired from the images (40, 41) are merged in a subsequent step on the basis of the 3D data of the at least one common point (44) such that the 3D data acquired from said images (40, 41) agree at least with reference to the 3D data of the common point (44) in the 3D data set.
    • 本发明涉及一种用于通过三角测量光学扫描物体的三维几何形状的方法,其中将图案(9,9')投射到待扫描的物体(7)上以获得3D数据 设置,并且将投影图案(9,9')记录在图像(40,41)中。 在用于生产至少一个第一图像(40)的第一步骤中,投影第一图案(9),并且在用于创建至少一个另外的图像(40)的第二步骤中,另外的图案(9') 偏离第一位置或形状的物体被投影到待扫描的物体(7)上并且产生图像(41)。 第一图像(40)和另外的图像(41)包括至少一个公共点(44)。 根据所述至少一个公共点(44)的3D数据,从所述图像(40,41)获取的3D数据在后续步骤中被合并,使得从所述图像(40,41)获取的3D数据一致 至少参考3D数据集中的公共点(44)的3D数据。

    • Methods and devices are provided for evaluating the presence of disease in a patient. In particular, methods and devices are provided for screening patients for neoplastic and/or inflammatory disease. Such diseases are often indicated by the elevated level of a chemical compound associated with disease, such as nitric oxide (NO) and/or nitrogen dioxide (NO2). Through measuring and/or estimating the chemical compound-concentration, such as by change in fluorescence, absorbance or reflectance, the methods and tools provided distinguish between patients who require further testing and/or treatment and those who do not. The methods and tools also provide information about the effectiveness of treatment, such as treatment to reduce inflammation or control of the growth of malignant tumors. These methods and devices are relatively inexpensive, easy to use, and provide other advantages.
    • 提供了用于评估患者疾病存在的方法和装置。 特别地,提供了用于筛选患者肿瘤和/或炎性疾病的方法和装置。 这些疾病通常由与疾病相关的化学化合物(例如一氧化氮(NO)和/或二氧化氮(NO2))升高的水平来指示。 通过测量和/或估计化学化合物浓度,例如通过荧光,吸光度或反射率的变化,所提供的方法和工具区分需要进一步测试和/或治疗的患者和不需要进一步测试和/或治疗的患者。 方法和工具还提供有关治疗有效性的信息,例如治疗以减少炎症或控制恶性肿瘤的生长。 这些方法和装置相对便宜,易于使用,并提供其他优点。

    • Apparatus and methods for monitoring a tooth may include sensing acoustic energy propagating from regions (such as a root canal system) in and/or near a tooth. The apparatus and methods may be used with root canal cleaning treatments to determine the efficacy of the treatment and/or to reduce risk of post- treatment complications. An acoustic source (e.g., an acoustic transducer and/or a high-speed liquid jet) may be used to transmit energy into a tooth and/or regions near a tooth. An acoustic receiver may be used to detect acoustic signatures of acoustic events (e.g., acoustic echoes and/or acoustic cavitation) occurring in the tooth. The acoustic signatures may be used, for example, to determine the progress of a root canal cleaning treatment and/or the presence or movement of material toward a periapical region of the tooth. Apparatus and methods for monitoring a tooth may include detecting impact of a first jet on a tooth and actuating a second jet in response to detection of the impact.
    • 用于监测牙齿的装置和方法可包括感测从牙齿中和/或牙齿附近的区域(例如根管系统)传播的声能。 该设备和方法可与根管清洁治疗一起使用以确定治疗的功效和/或降低治疗后并发症的风险。 可以使用声源(例如声学换能器和/或高速液体喷射器)将能量传输到牙齿附近的牙齿和/或区域。 可以使用声学接收器来检测在牙齿中发生的声学事件(例如声学回声和/或声学空化)的声学标记。 例如,可以使用声学特征来确定根管清洁处理的进展和/或材料朝向牙齿的根尖区域的存在或运动。 用于监测牙齿的装置和方法可以包括检测第一射流对牙齿的冲击并且响应于检测到冲击而致动第二射流。
