    • Uterine cervical cancer Computer-Aided-Diagnosis (CAD) according to this invention consists of a core processing system that automatically analyses data acquired from the uterine cervix and provides tissue and patient diagnosis, as well as adequacy of the examination. The data can include, but is not limited to, color still images or video, reflectance and fluorescence multi-spectral or hyper-spectral imagery, coherent optical tomography imagery, and impedance measurements, taken with and without the use of contrast agents like 3-5% acetic acid, Lugol's iodine, or 5-aminolevulinic acid. The core processing system is based on an open, modular, and feature-based architecture, designed for multi-data, multi-sensor, and multi-feature fusion. The core processing system can be embedded in different CAD system realizations. For example: A CAD system for cervical cancer screening could in a very simple version consist of a hand-held device that only acquires one digital RGB image of the uterine cervix after application of 3-5% acetic acid and provides automatically a patient diagnosis. A CAD system used as a colposcopy adjunct could provide all functions that are related to colposcopy and that can be provided by a computer, from automation of the clinical workflow to automated patient diagnosis and treatment recommendation.
    • 根据本发明的子宫颈癌计算机辅助诊断(CAD)包括一个核心处理系统,其自动分析从子宫颈获得的数据,并提供组织和患者诊断以及检查的充分性。 数据可以包括但不限于彩色静止图像或视频,反射率和荧光多光谱或超光谱图像,相干光学断层摄影图像和阻抗测量,在使用和不使用造影剂如3- 5%乙酸,Lugol碘或5-氨基乙酰丙酸。 核心处理系统基于开放,模块化和基于特征的架构,专为多数据,多传感器和多功能融合而设计。 核心处理系统可以嵌入到不同的CAD系统实现中。 例如:用于宫颈癌筛查的CAD系统可以在非常简单的版本中由手持装置组成,其仅在施加3-5%乙酸后才获得子宫颈的一个数字RGB图像,并自动提供患者诊断。 用作阴道镜附件的CAD系统可以提供与阴道镜相关的所有功能,并且可以由计算机提供从临床工作流程自动化到自动化患者诊断和治疗推荐的所有功能。

    • The image registration systems and methods according to this invention register reflectance and fluorescence hyperspectral imagery and provide the spatial image transformation between the reflectance and fluorescence hyperspectral imagery. A reflectance image is embedded into the fluorescence hyperspectral imagery and thereby resolves the resemblance problem of reflectance and fluorescence hyperspectral imagery. The reflectance image is embedded into the fluorescence hyperspectral imagery using (1) light from a narrow-band source embedded in Ultraviolet (UV) excitation light, (2) second order diffracted light, and/or (3) Ultraviolet (UV) excitation light reflectance. Resembling reflectance images are calculated from the reflectance hyperspectral imagery and the embedded reflectance image in the fluorescence hyperspectral imagery. The two respective reflectance images are pre-processed to maximize the resemblance between them. Image registration algorithms use the two pre-processed reflectance images and calculate the spatial image transformation that allows to map the spatial coordinates from the reflectance to the fluorescence hyperspectral imagery (and vice versa).

    • An electromagnetic actuator for operating a driven component includes first and second electromagnets having respective first and second pole faces oriented toward one another and defining a space therebetween; an armature disposed between the electromagnets and movable back and forth between the first and second pole faces in a direction of motion; a driving component attached to the armature for moving therewith as a unitary structure; and a resetting spring unit attached solely to the driving component or the driven component and exerting forces opposing movements of the armature caused by electromagnetic forces generated by the electromagnets. The resetting spring unit is in a relaxed state when the armature is in a mid position between the first and second pole faces and is in an armed state upon movement of the armature from the mid position in either direction. A mechanism connects the driving component with the driven component for effecting a transmission of moving forces from the driving component to the driven component to cause displacements of the driven component as a function of displacements of the armature and the driving component.
