摘要:
The invention provides a system (102) for accurately detecting a patient's (114) movement during imaging procedures. The system comprises a camera (126) for providing a stream of camera images of a part of a patient's exterior (206). The system (102) furthermore comprises a fiducial element (116), which fiducial element (116) is mountable on said part of the patient's exterior (206), and which fiducial element (116) is detectable in the stream of camera images, and an image processor (128) for detecting a displacement of the fiducial element based on consecutive camera images comprised in at least the stream of camera images and for generating an output signal (129) indicative for said displacement. Herein, the fiducial element (116) has an in-plane stiffness which is substantially larger than an in-plane stiffness of said part of the patient's exterior. In addition, the fiducial element (116) and said part of the patient's exterior are provided with substantially equal outer in-plane dimensions.

A system is provided that may be used for locating and diagnosing lesions in the human body in vivo. In some embodiments, once the exact position of a lesion is found, a biopsy may be taken from the lesion using e.g. ultra sound techniques for guidance of the biopsy needle. Use of the system drastically reduces the negative biopsy samples compared to currently used “blind sampling” techniques. This reduces patient discomfort and minimizes infections as the number of biopsy samples is reduced. A method and computer-readable medium is also provided.

A system for imaging of prostate cancer in a prostate in vivo is provided. The system utilizes Diffuse Optical Tomography (DOT) for creating a 3D image for the detection of suspicious prostate tissue. The DOT image may be used to guide the biopsy, thereby reducing the number of false negatives. A method, computer-readable medium and use are also provided.

The optical analysis system (20) for determining an amplitude of a principal component of an optical signal comprises a multivariate optical element (10) for reflecting the optical signal and thereby weighing the optical signal by a spectral weighing function, and a detector (9, 9P, 9N) for detecting the weighed optical signal. The optical analysis system (20) may further comprise a dispersive element (2) for spectrally dispersing the optical signal, the multivariate optical element being arranged to receive the dispersed optical signal. The blood analysis system (40) comprises the optical analysis system (20) according to the invention.

This application describes a medical device (230) for obtaining optical tissue properties of a target material. The medical device (230) comprises an elongated body (231) having a longitudinal axis (232) and an optical fiber being integrated within the elongated body (231). The optical fiber has a second fiber end (242, 242a, 242b), which is arranged at a side wall (233) of the elongated body (231) and which provides a lateral field of view with respect to the longitudinal axis (232). According to an embodiment many optical fibers are integrated each having an optical outlet (242, 242a, 242b) around the elongated body (231). Using the outlets (242, 242a, 242b) to do diffuse optical tomography and also use optical fibers to do an optical inspection, one can get information on the presence of tumors in a volume around the medical device (230) and a tissue characterization in the vicinity of the medical device (230). Thereby, an optical biopsy may be carried out, wherein no real tissue is removed. According to another embodiment an optical detection system is integrated into a real biopsy needle (330) allowing inspection and taking real biopsy simultaneously.
摘要:
A system for generating an image including information of both an interior and an exterior of a patient. The system includes an X ray device for providing an X ray image of a patient's interior, and a camera responsive to a wavelength for providing a camera image of a patient's exterior. The camera may be supported by the X ray device for establishing a determined spatial relationship between the camera and the X ray device. The system further includes a spatial reference for spatially correlating the X ray image and the camera image, where the spatial reference is detectable in the X ray image and in the camera image. A data processor configured for rendering the camera image and the X ray image into a composite image on the basis of the spatial reference.
