Aspects of the present disclosure disclose a system and method for delivering for administering radiation to a patient. The method may include associating the patient with one of a plurality of coded dosage zones wherein each of the plurality of coded dosage zones corresponds to one or more values of a physical characteristic. The method may further include correlating the one of the plurality of coded dosage zones to a dose of radiation and then applying the dose of radiation to the patient.

An improved configuration of a mobile-type radiographic image pickup device reliably stops on a flat path without play. More specifically, the prevent invention stops reliably on an inclined path. Where a carriage accelerates regardless of that fact that a deceleration control unit has begun to restrict the movement of the carriage, a brake control unit causes a brake device to operate. According to the present invention, if the carriage accelerates regardless of the fact that a deceleration control unit has begun to restrict the movement of the carriage, the brake device is promptly operated, and prevents concern regardless of the application of an instruction to stop the carriage which is travelling on an incline, and prevents the carriage from running for a long period to time.

A shield structure configured to protect a head and/or neck of a patient during a radiologic procedure comprises a bottom wall, a side wall, and an opening. The bottom wall includes radiation attenuating material and is configured to be positioned between the head and/or neck of the patient and a radiation source so as to shield the patient from radiation directed toward the bottom of the patient. The bottom wall is of a general size to shield the head and/or neck of the patient. The side wall includes radiation attenuating material and is configured to extend upward from the bottom wall so as to shield the patient from radiation directed toward a side of the patient. The opening is configured to receive the head and/or neck of the patient.

Disclosed is a radiation protection barrier. The radiation protection barrier includes at least one plain panel, each including an elongate frame, and a protective sheet attached to the elongate frame. The radiation protection barrier also includes at least one interventional panel coupled to the at least one plain panel, each of the at least one interventional panel(s) including an elongate frame, a protective sheet movably arranged on the elongate frame, a pair of sterile gloves arranged at an intermediate portion of the protective sheet, and a window configured on the protective sheet under the pair of sterile gloves. The radiation protection barrier further includes a plurality of wheel arrangements coupled to the elongate frames of the at least one plain and interventional panels.

A collision sensor device for a medical apparatus includes a sensor structure having a first sensor and a second sensor that are separated by a spacer layer, at least one crumple layer that adjoins one of the first sensor and the second sensor and is configured to provide a run-on path, and an outer surface layer provided on a side facing away from the medical apparatus in an installed state of the collision sensor device.

A radiation shield assembly is described, configured to block radiation emanating from a radiation source from reaching a user. Two shields are supported by a support arm, and are configured to rotate relative to one another. This allows the shield to be easily configured and reconfigured as necessary to safely visualize various parts of a patient's body via radiography.

Provided herein is technology relating to controlling radiation and protecting biological organisms from exposure to radiation and particularly, but not exclusively, to apparatuses, methods, and systems for minimizing and/or eliminating exposure of humans to stray radiation used for medical imaging and therapy.

A controller and a related method of controlling a collimator. The controller operates to select a collimator setting for collimator of an x-ray imager for acquiring an image of a ROI in a patient. The controller operates to select the collimator setting to optimize the patient dosage in respect of primary radiation and secondary radiation dosage of medical staff. A position detector supplies to the controller a current position of a person relative to a patient. Based on said supplied position, the controller's configured to perform an optimization procedure that takes into account the staff dosage in respect of the secondary radiation dosage to reduce the secondary radiation dosage.

A system for navigating a medical device is provided. In one embodiment, a magnetic field generator assembly generates a magnetic field. Position sensors on the medical device, on an imaging system and on the body generate signals indicative of the positions within the magnetic field. The generator assembly and reference sensors are arranged such that a correlation exists between them and the positions of the body and of a radiation emitter and a radiation detector of the imaging system. An electronic control unit (ECU) determines, responsive to signals generated by the sensors, a position of the medical device, a position of one of the radiation emitter and detector and a distance between the emitter and detector. Using this information, the ECU can, for example, register images from the imaging system in a coordinate system and superimpose an image of the device on the image from the imaging system.

Provided is a mammography apparatus that prevents a main body from falling due to damage to a coupling connecting a ball screw, to which the main body is connected, and a motor. The mammography apparatus includes: a main body having an X-ray generator and an X-ray detector; a ball screw to which the main body is connected so as to be movable up and down; a motor rotating the ball screw so as to allow the main body to move up and down; a coupling connecting a drive shaft of the motor and the ball screw; and a brake provided at one side of the coupling. When the coupling is ruptured, the brake prevents ruptured coupling portions from being separately rotated in order to prevent a fall of the main body.
