Self-shielded ct scanner

A CT scanner includes a pair of shields to protect an operator from x-rays from the CT scanner. The CT scanner has a gantry that provides structural support and housing for the components including an x-ray source and a detector arranged on the gantry to face one another. Lead shields are located on opposing sides of the x-ray source and extend between the x-ray source and the detector. The CT scanner further includes a computer located on an opposing side of the gantry from the x-ray source and the detector. The lead shields rotate with the gantry and prevent the x-ray from reaching the operator while the CT scanner is in operation.

Multiple source ct scanner

A CT scanner includes a plurality of cone-beam x-ray sources offset along a CT axis. A detector is positioned opposite the x-ray sources. The x-ray sources and detector are rotatable about the CT axis. The x-ray sources direct x-rays through the patient that are received by the detector at a plurality of rotational positions, thereby generating projections from the plurality of x-ray sources that are used to construct the three-dimensional CT image of the patient.

Ct scanner with helical path source

An example CT scanner assembly includes a gantry having a first end and a second end rotatable about a first axis, an x-ray detector adjacent the first end, and an x-ray source adjacent the second end. The x-ray source directs an x-ray beam toward a portion of the x-ray detector. The x-ray source translates along a second axis aligned with the first axis when the gantry rotates.

Ct scanner for lower extremities

A CT scanning system provides the ability to scan a patient's lower extremities while the patent is upright, i.e. either standing on the foot, or at least putting some load on the foot, or with the ankle at a given angle. The CT scanning system provides a generally horizontal upper support surface on which the patient's foot is supported. A gantry supporting an x-ray source and x-ray detector are rotated about a z-axis through the support surface. With the CT scanning system, the patient's lower extremities can be scanned while under load.

Method and apparatus for adjusting a scanning region in a computed tomography system

A method and an apparatus are provided for adjusting a scanning region of a computed tomography (CT) scanner. At least one edge point of a set-point scanning region on a patient examination table associated with the CT scanner is indicated by hand signals of a user. Via a distance sensor, mounted at a reference point of the patient examination table, a distance from the at least of edge point to the reference point is measured. From the measured distance, the position of the at least one edge point relative to the patient examination table is determined, and a corresponding edge of a CT scanning region of the CT scanner is conformed to the derived position.
