OPTICAL IMAGING SYSTEM AND METHODS THEREOF
An optical imaging system to image a target object includes a light source configured to emit one or more light rays to illuminate the target object and an image detector configured to capture a three-dimensional topography image of the target object when emitted light is emitted from the target object in response to being illuminated by the light rays emitted by the light source. A fluorescence image detector captures a fluorescence image of the target object when fluorescence is emitted from the target object in response illumination by light rays emitted by the light source. A controller instructs the image detector to capture the 3D topography image and the fluorescence image detector to detect the fluorescence image of the target object intraoperatively and to co-register and simultaneously display intraoperatively the co-registered topography and fluorescence information to the user via a display.
COMPUTER TOMOGRAPHY APPARATUS
The invention relates to a computer tomography apparatus for examining a body part of a large animal, comprising a computer tomography (CT) device and a platform on which the CT device is mounted. The CT device has an annular gantry and a CT table to accommodate a body part of a large animal to be examined. The gantry is immovable relative to the platform. Relative to the platform and to the gantry the CT table is horizontally movably connected to the gantry and/or the platform in such a way that the CT table can be moved into a central opening in the annular gantry. The computer tomography apparatus further comprises a positioning device which is connected to the platform and is designed to position the platform having the mounted CT device relative to a supporting surface for a large animal. The positioning device is designed to position the platform having the mounted CT device in an operational state in such a way that during a relative movement with respect to the gantry the CT table remains stationary relative to the supporting surface.
Method and apparatus for reconstructing a three-dimensional representation of a target volume inside an animal or human body
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.

Methods and systems for image-guided radiation therapy
A radiation therapy system is equipped with a combined imaging system, such as an imaging system combining computed tomography (CT), spectral CT, and single photon emission tomography imaging (SPECT), for guidance of radiation beams providing radiotherapy. The system can include at least one x-ray source that emits an x-ray beam at a low energy level for imaging and/or an x-ray beam at a high energy level for radiation therapy. The system can also include at least one imager, such as a cadmium zinc telluride (CZT) or cadmium telluride (CdTe) flat-panel imager that receives x-ray beams traversing a subject from the x-ray source and gamma rays emitted by radioisotope tracers injected into the subject. Based on the guidance of the triple images (CT, spectral CT, and SPECT), a computer system can control the radiation therapeutic beam delivery to target areas, such as lesions and/or tumors.

Medical Imaging System And Methods
A mobile medical imaging device that allows for multiple support structures, such as a tabletop or a seat, to be attached, and in which the imaging gantry is indexed to the patient by translating up and down the patient axis. In one embodiment, the imaging gantry can translate, rotate and/or tilt with respect to a support base, enabling imaging in multiple orientations, and can also rotate in-line with the support base to facilitate easy transport and/or storage of the device. The imaging device can be used in, for example, x-ray computed tomography (CT) and/or magnetic resonance imaging (MRI) applications.
Small animal X-ray positioner
An x-ray positioning stand, for holding an x-ray generator, includes a base having a primary base member, a first extension arm, and a second extension arm. The primary base member extends in a longitudinal direction along the length from a first end to a second end, and extends in a transverse direction along the width from a front side to a rear side. The first extension arm is pivotably connected to the primary base member proximate the first end and the second extension arm is pivotably connected to the primary base member proximate the second end. The stand also includes a support rod having a lower end connected to a central portion of the primary base member and an upper end having an attachment head connectable to the x-ray generator, and configured for supporting the x-ray generator over a subject to be imaged. Each of the first extension arm and the second extension arm are pivotable from a stored position to a deployed position. The free ends of the first extension arm and the second extension arm are closer to each other in the stored position than in the deployed position.
