An imaging apparatus and method are provided. The probe for an imaging apparatus includes a manually manipulable proximal portion; a straight distal portion with a distal tip for locating at a site to define an observational field; and a curved portion between the proximal portion and the distal portion. The imaging method includes the steps of locating a distal tip of an imaging probe at a site to define an observational field; irradiating the observational field from the distal tip; and collecting a return signal at the distal tip; wherein the probe comprises a manually manipulable proximal portion. The apparatus and method provided herein are useful for various applications including but not limited to endomicroscopy and other microsurgical procedures performed under optical stereoscopic magnified visualization, such as neurosurgery, ENT/facial surgery and spinal surgery.

Imaging method and apparatus

A surgical microscope has an illuminating arrangement for illuminating light in an operating region to be examined with the surgical microscope. The arrangement contains a high-power light source which includes an intensity adjusting device. The device makes possible an adjustment of the intensity of the illuminating light, which is guided to the object region, between a maximum value and a minimum value. The microscope has a control unit for the illuminating arrangement which includes an operator-controlled module via which the illuminating arrangement can be activated and controlled. For adjusting the intensity of the illuminating light guided to the operating region, the control unit coacts with the adjustable filter unit. A signal generator outputs a warning signal when an intensity of the illuminating light is adjusted via the operator-controlled module which exceeds the safety limit value stored in a memory.

Surgical microscope for use in surgical procedures including neurosurgery

A surgical microscope () is especially suited for use in neurosurgery. The surgical microscope has an illuminating arrangement () for making available illuminating light in an operating region () to be examined with the surgical microscope (). The illuminating arrangement () contains a high-power light source () which includes an intensity adjusting device (). The intensity adjusting device () makes possible to adjust the intensity of the illuminating light (), which is guided to the object region (), between a maximum value and a minimum value. The surgical microscope () has a control unit () for the illuminating arrangement () which includes an operator-controlled module () via which the illuminating arrangement () can be activated and controlled. For adjusting the intensity of the illuminating light () guided to the operating region (), the control unit coacts with the adjustable filter unit (). A signal generator () is provided which outputs a warning signal when an intensity of the illuminating light is adjusted via the operator-controlled module () which exceeds the safety limit value stored in a memory ().

A coherence microscope has a divider () that divides light emitted by a light source () into measurement light, which is supplied to and reflected by a specimen (), and reference light. A superimposition device () superimposes the measurement light reflected by the specimen () with the reference light. A short sensor array () detects the light resulting from the superimposition and permits a read-out rate of at least about 60 kHz. The superimposition device has an emission device () for emitting the measurement light and the reference light arranged to effect extensive irradiation of the sensor array () with superimposed light. The ratio of distances covered by the measurement light and the reference light from the emission device () to impingement points on the sensor array () varies in the portion of the sensor array () that is irradiated with superimposed light.

An image sensor and a circuitry associated with the image sensor is used for recording a series of fluorescence images. The image sensor comprises a plurality of pixels for accumulating charges generated by incident radiation, and the circuitry converts the charges accumulated in the pixels into binary numbers. A gain of the circuitry is adjustable. The gain is set to a suitable maximum value at the beginning of a recording procedure. The gain is reduced if it is determined during the recording procedure that one or more brightness values of the recorded image exceed a suitably chosen maximum brightness value.

Microscopy system and recording method for visualizing fluorescence

An optical imaging system, for example, for a surgical microscope () has a beam deflecting unit in order to cast light rays out of an object region () into an image plane () with an optical beam path. An optical phase plate () is mounted in the optical beam path. In the optical imaging system, a unit for generating a geometric image of the image plane is provided, for example, an ocular unit (). The optical phase plate () is arranged on the end of the objective lens () facing away from the object or is arranged in a region of the optical imaging system in which the beam path is parallel.
