Provided herein are imaging systems for a patient including an imaging probe and an imaging assembly. The imaging probe includes: an elongate shaft with a proximal end, a distal portion, and a lumen extending between the proximal end and the distal portion; a rotatable optical core with a proximal end and a distal end, and at least a portion of the rotatable optical core is positioned within the lumen of the elongate shaft; and an optical assembly positioned proximate the distal end of the rotatable optical core, the optical assembly configured to direct light to tissue to be imaged and collect reflected light from the tissue to be imaged. The imaging assembly is constructed and arranged to optically couple to the imaging probe. The imaging assembly is configured to emit light into the imaging probe and receive the reflected light collected by the optical assembly.

Presented herein is a method of using a manually-operated light plane generating module to make accurate measurements of the dimensions of an object seen in an image taken by an endoscopic camera. The method comprises: providing the light plane generating module with distinctive features, introducing the light plane generating module until the distinctive features are visible in the image, aligning the light plane across the object, and providing a processor device and software configured to analyze the camera images. Also described are diagnostic or therapeutic endoscopic tools that comprise an attached light plane generating module to provide the tool with integrated light plane measurement capabilities, wherein the tool is configured to be used in the described method.

There is provided a system for cardiac electromagnetic/magnetic catheterization for diagnosing and treating blood vessels of a patient. The system having at least one electromagnetic intraluminal capsule able to force its way through a narrowing blood vessel, the capsule carrying a camera allowing visualization of blood vessels of a patient. There is a portable electromagnetic tip, where the tip pulls the electromagnetic capsule by electromagnetic force, and when the magnetic tip moves along a body of a patient and pulls the intraluminal electromagnetic capsule along with it towards a narrowing blood vessel visualized by the camera, so that the capsule then treats the narrowing site and clears the blood vessel from coronary plaque. In addition working capsule can replace diseased valve in any cardiac position for either temporary or permanent needs.

There is described an apparatus comprising a first optical element, a second optical element and a spacing element for use with a mobile user device. The first optical element is configured to provide an image of an object to an intermediate image plane and the second optical element magnifies the image to provide a final image in a final image plane in which a camera aperture of the device is supported. The spacing element maintains a fixed separation between the object and the first optical element. Image magnification is achieved while also providing a space for tool access. Mirrors may be used to divert the optical path, allowing the optical path to be folded for more compact apparatus. A third optical element disposed at the intermediate image plane may be used to reduce vignetting effects in the final image.

An image capturing apparatus includes: a columnar main body having proximal and distal ends, and having a predetermined length therebetween so as to enable insertion of at least the distal end into an oral cavity; at least one light source provided on the proximal or distal end side of the main body, or to the main body, configured to emit light having a predetermined frequency band; a diffuser plate provided on the proximal or distal end side of the main body, or to the main body, configured to diffuse the emitted light toward the oral cavity; and a camera provided on the proximal or the distal end side of the main body, or to the main body, configured to capture an object image based on reflected light which has been diffused by the diffuser plate and reflected from the oral cavity.

A signal processing device includes a processor including at least one or more pieces of hardware. The processor is configured to: when a first synchronization signal from a first synchronization signal generation circuit, the first synchronization signal generation circuit receiving a first clock signal and outputting the first synchronization signal, and a second synchronization signal output from a second synchronization signal generation circuit are not synchronized, reset the first synchronization signal generation circuit, and in a period in which the first synchronization signal generation circuit is reset, set a frequency of the first clock signal to be higher than a frequency in another period.

An endoscope includes, in a distal end frame constituting a distal end portion, an objective optical unit including a voice coil motor that moves a moving lens frame forward and backward in a direction of an optical axis by using a plurality of magnets arranged on a periphery of the moving lens frame, and a plurality of internal components made of magnetic material and arranged around the objective optical unit. At least one of the internal components is arranged at a position where at least a part thereof intersects one of straight lines each connecting an extreme point of one of valleys of a specific isomagnetic line of magnetic fields formed by the magnets and one of two inflection points of the specific isomagnetic line, the two inflection points being located, with the one of the valleys positioned between the two inflection points.

Provided is an ultrasonic endoscope with which it is possible to improve a brush cleanability of a communication path. A distal end portion (44) of an ultrasonic endoscope (10) includes: a balloon attachment portion (152) for attachably and detachably attaching a balloon (60) to the distal end portion (44), the balloon attachment portion (152) including a first balloon groove (154) that is provided over an outer periphery of the distal end portion at least on a proximal end side of an ultrasound oscillator (92); and a communication path (90) for supply or suction of a fluid with respect to an inner space of the balloon (60). An entrance and exit way (91) of the communication path (90) is formed to be diagonally inclined with respect to a longitudinal axis of an insertion portion (12). The first balloon groove (154) includes a shallow groove portion (158) that is formed to have a groove depth smaller than other portions in a circumferential direction of the distal end portion (44), and the entrance and exit way (91) of the communication path (90) is provided in an internal region of the distal end portion (44) where the shallow groove portion (158) is formed.
