A differential interference contrast (DIC) determination device and method utilizes an illumination source, a layer having a pair of two apertures that receive illumination from the illumination source, and a photodetector to receive Young's interference from the illumination passing through the pair of two apertures. In addition, a surface plasmon assisted optofluidic microscope and method utilize an illumination source, a fluid channel having a layer with at least one aperture as a surface, and a photodetector that receives a signal based on the illumination passing through the aperture. The layer is corrugated (e.g., via fabrication) and parameters of the corrugation optimize the signal received on the photodetector.

Process for managing the representation of at least one model of a scene including buildings intended to be transmitted to a client. The scene is modelled by a multi-scale tree-structured representation. Different nodes are associated with the different levels of details of the scene. These different nodes are dependent on each other in a tree structure in which at least one son node is defined by information known by a father node and by additional information in respect of the son node. A processing operation to simplify the representation is applied to the modelling and priorities for implementing the simplification processing operations are determined by a cost function which takes account of the criterion of the difference in height of the merged buildings.

The invention relates to method and apparatus for reconstructing a three-dimensional representation of a target volume inside an animal or human body.Hereto, according to the method step ii) is preceded by the steps of:a1) displaying said first two-dimensional image projection being obtained in step i) for a user using said displaying means,a2) acquiring a first operational orientation setting of said imaging means corresponding with said first imaging position;a3) defining based on said first operational orientation setting a first set of second operational orientation settings of said imaging means for orientation in a second imaging position;a4) selecting from said set one of said second operational orientation settings;a5) using said second operational orientation setting being selected for acquiring said second two-dimensional image projection of said target volume using said imaging means being positioned in the second imaging position corresponding to said second operational orientation setting.Accordingly, with these features an improved reconstructing method is obtained, wherein an optimal set of two-dimensional image projections is obtained and proposed, based on which a correct three-dimensional contour image of said target volume is being reconstructed. Thus with this correct three-dimensional contour image the diagnostician is capable of performing a more accurate diagnosis and subsequent treatment of the patient, which in turn is subjected to a less lengthy imaging treatment session, which is beneficial in terms of radiation exposure time, discomfort, etc.

Disclosed herein is a 3-D image display unit that can be controlled flexibly to protect the user from eyestrain and operated easily. The 3-D image display unit includes measuring means for measuring a display time of a 3-D image, parallax adjusting means for instructing 3-D image forming means to adjust the parallax of the 3-D image. In the case where the 3-D image display time measured by the measuring means exceeds a predetermined time, the parallax adjusting means instructs the 3-D image forming means to reduce the parallax of the 3-D image to be formed, thereby the display means comes to display a 3-D image having a small parallax. The user can thus be protected from eyestrain.

A surface coil array comprises a surface coil support and an arrangement of non-overlapping magnetically decoupled surface coils mounted on the support. The surface coils encompass a volume into which a target to be imaged is placed. Magnetic decoupling circuits act between adjacent surface coils. Impedance matching circuitry couples the surface coils to conventional transmit and receive components.

A thermoacoustic imaging device is provided having a transmitter configured to provide an electromagnetic transmit signal (e.g. a continuous sinusoidal signal) to an object being imaged. The transmit signal is a modulated continuous-wave signal based on a carrier frequency signal fc modulated at a modulation frequency at or near fm. The detector is further configured to receive an acoustic signal from the object being imaged, and is responsive to acoustic frequencies at or near 2fm. A non-linear thermoacoustic effect in the object being imaged generates the acoustic signal from the object being imaged. Spectroscopic maps could be generated and imaged object could be analyzed. The device enhances signal-to-noise ratio of the reconstructed image and reduces the requirement of peak power in thermoacoustic imaging systems. In addition, the generated pressure of the imaged object is separated from microwave leakage and feedthrough in frequency through the nonlinear thermoacoustic effect.
