An N-M tomography system comprising: a carrier for the subject of an examination procedure; a plurality of detector heads; a carrier for the detector heads; and a detector positioning arrangement operable to position the detector heads during performance of a scan without interference or collision between adjacent detector heads to establish a variable bore size and configuration for the examination. Additionally, collimated detectors providing variable spatial resolution for SPECT imaging and which can also be used for PET imaging, whereby one set of detectors can be selectably used for either modality, or for both simultaneously.

The present invention provides a breast computed tomography system in which the body motion and the pain of an examinee during capturing of images of the breast are reduced. The breast computed tomography system includes a gantry accommodating a light emitting unit that radiates light onto the breast. The gantry includes a gripper having a right gripping portion and a left gripping portion.

A system and method are provided for performing fluoroscopic procedures with assistance of guiding laser beam projections to reduce a reliance on harmful radiation emitting fluoroscopic imaging devices during the procedure. The system and method reduce an amount of radiation exposure to patients and medical personnel during procedures that require assistive real-time imaging. Specifically, an automated laser guidance system and method of use is provided to reduce fluoroscopic radiation, reduce operation time, and increase operative accuracy.

The disclosure relates to a system and method for medical imaging. The method may include: move, by a motion controller, a phantom along an axis of a scanner to a plurality of phantom positions; acquire, by a scanner of the imaging device, a first set of PET data relating to the phantom at the plurality of phantom positions; and store the first set of PET data as an electrical file. The length of an axis of the phantom may be shorter than the length of an axis of the scanner, and at least one of the plurality of phantom positions may be inside a bore of the scanner.

A Compton camera for medical imaging is divided into segments with each segment including part of the scatter detector, part of the catcher detector, and part of the electronics. The different segments may be positioned together to form the Compton camera arcing around part of the patient space. By using segments, any number of segments may be used to fit with a multi-modality imaging system.

An imaging apparatus comprises a rotatable gantry system positioned at least partially around a patient support; a first source of radiation coupled to the rotatable gantry system, the first source of radiation configured for imaging radiation; a second source of radiation coupled to the rotatable gantry system; and a first radiation detector coupled to the rotatable gantry system and laterally movable relative to a central beam of the first source of radiation to receive radiation from at least the first source of radiation over various fields of view. Alternative configurations of the imaging apparatus and methods of using the imaging apparatus are also provided.

An imaging apparatus for use with an imaging device in order to image a subject. The imaging device includes an annular gantry having an opening and a table to accommodate the subject or a portion thereof for imaging. The imaging apparatus includes a platform and a positioning device. The imaging device is mounted to the platform. The annular gantry is in a fixed position relative to the platform. The table is horizontally displaceable relative to the annular gantry. The positioning device supports the platform and is configured to horizontally displace the platform relative to a supporting surface for the subject. The positioning device is configured to position the platform with the imaging device in at least one operational state in such a way that, during a relative movement of the table with respect to the annular gantry, the table remains stationary relative to the supporting surface.

To produce 3D x-ray images, it is necessary to compensate for patient movement during the emission and detection of x-rays; this may be achieved by providing an x-ray sensor 20 comprising a digital x-ray detector 40, and an inertial sensor 50, 60 for providing positional information relating to changes in the relative position of the x-ray sensor during detection of x-rays.

A radiation detector includes a sensor substrate, a conversion layer, and a reinforcing substrate. In the sensor substrate, a plurality of pixels for accumulating electric charges generated in response to light converted from radiation are formed on a pixel region of a flexible base material. The conversion layer is provided on a first surface of the base material on which the pixels are provided and converts radiation into light. The reinforcing substrate is provided on a surface of the conversion layer opposite to a surface on the base material side and includes a porous layer having a plurality of through-holes to reinforce the stiffness of the base material.
