The present disclosure provides a method and system for controlling a medical device. The method for controlling the medical device may include: obtaining information related to the medical device and/or information related to a target object; controlling the medical device based on the information related to the medical device and/or the information related to the target object.

An apparatus for Digital Imaging in the Head Region of a Patient includes an X-ray source and an X-ray sensor, supported on i a rotary arm supported on a structure by a motor driven translation and rotation means. The rotary arm is provided with adjustment means for varying the distance between the source and the sensor. The apparatus comprises a single sensor for both panoramic imaging and computed tomography, and has a control unit, that controls the source, the sensor, the adjustment means, and the translation and rotation means and operates the apparatus in a basic operation mode for bigger patients and in an alternative operation mode for smaller patients, in which the distance between the source and the sensor is reduced as compared to the distance used for the basic operation mode.

An X-ray computed-tomography (CT) apparatus according to an embodiment includes an X-ray tube, a detector, a table top, and processing circuitry. The X-ray tube generates an X-ray. The detector detects the X-ray. On the table top, a subject is placed. The processing circuitry controls a moving mechanism to move the table top in a longitudinal direction. The processing circuitry displays information indicating magnitude of a vibration that occurs, when each position in the longitudinal direction on the table top is moved to a position intersecting a path of the X-ray, at the position.

A radiation detecting apparatus detects radiation transmitted through a subject. The radiation detecting apparatus includes a hardware processor. The hardware processor detects rotation angles of the radiation detecting apparatus with respect to two mutually perpendicular axes to output angle information, and also detects an orientation of the radiation detecting apparatus. The hardware processor outputs the angle information for the detected orientation.

The invention relates to positioning a volume to be imaged for computed tomography imaging. According to the invention, at least two optical cameras (22) are used for taking a photo or for live imaging an anatomy from different directions. A volume positioning indicator (42) is shown in connection with these images, the volume positioning indicator (42) indicating the location of the volume within the area imaged by the cameras (22) to get imaged by the computed tomography imaging apparatus (10).

A method for fluoroscopy energizes a radiation source to form a scout image on a detector and processes the scout image to determine and report a radiation field position with respect to a predetermined zone of the detector. The radiation source is energized for fluoroscopic imaging of a subject when the reported radiation field position is fully within the predetermined zone.

An extra-oral imaging apparatus is intended to obtain a cephalmetric image of a portion of a head of a patient. Exemplary apparatus embodiments of cephalometric functionality of such extra-oral imaging apparatus can include a cephalometric sup port mounted to a base of the imaging system that is configured to position a cephalometric sensor about a cephalometric imaging area so that x-rays impinge the cephalometric sensor after radiating the cephalometric imaging area. A cephalometric patient positioning unit mounted to the cephalometric support can be positioned between an x-ray source of the x-rays and the cephalometric sensor. A cephalometric alignment sight can be mounted to patient positioning unit to provide a visual indication of alignment between the x-ray source and the mounted alignment sight/cephaolmetric sensors. Exemplary methods are provided that can use such exemplary cephalometric alignment sights and/or install cephalometric functionality to imaging systems using the same.
