An eye mask apparatus for protecting a patient's eyes during dental or other radiography (i.e., “x-rays”) has an eye covering portion including a lead vinyl sheet. The lead vinyl sheet has a perimeter configured such that the lead vinyl sheet can completely cover a patient's eyes. The eye covering portion includes a first side and a second side. A trim portion extends around the perimeter, with the trim portion extending inward over a portion of the first side and the second side. A retaining band is coupled to the eye covering portion at a first attachment point and a second attachment point. The retaining band is configured to hold the eye covering portion against the patient's eyes when the mask is worn.

The present disclosure relates to an X-ray device, and an X-ray device according to an embodiment of the present disclosure comprises: a radiator configured to radiate an X-ray; a distance measurement sensor configured to measure a value of a distance to an object; and a controller configured to acquire a first separation distance between an X-ray radiation focal point of the radiator and a subject, and control operation of the radiator based on the acquired first separation distance. Through these, the radiation of the X-ray can be prevented without a physical skin guard when the subject approaches within a certain distance from the radiator, thereby preventing the increase in the size caused by the installation of the physical skin guard, and a process of manually setting a strength of the X-ray radiation output according to the thickness of the subject can be omitted, thereby improving easiness of the X-ray imaging and reducing the time for the X-ray imaging.

Apparatuses (devices, systems) and methods for shielding (protecting) surroundings around periphery of regions of interest located inside objects (e.g., patients) from radiation emitted by X-ray systems towards the objects. Apparatus includes: at least one radiation shield assembly including a support base connectable to an X-ray system radiation source or detector, and a plurality of radiation shield segments sequentially positioned relative to the support base, thereby forming a contiguous radiopaque screen configured for spanning around the region of interest periphery with a radiopaque screen edge opposing the object. Radiation shield segments are individually, actively controllable to extend or contract to selected lengths with respective free ends in directions away from or towards the support base(s), for locally changing contour of the radiopaque screen edge. Applicable for shielding (protecting) medical personnel, and patients, from exposure to X-ray radiation during medical interventions or/and diagnostics.

A method for tracking the position of a person in an environment, such as a medical room, relative to a medical device is presented. The method comprises identifying the position of a medical device in the environment, providing a mobile device in the vicinity of a person in the environment, the mobile device configured to follow movement of the person in the environment, and identifying the position of the mobile device in the environment by using at least one stationary device. Further, the method comprises using a processor to process data relating to the position of the mobile device in the environment to obtain an expected position of the person in the environment, data relating to the position of the medical device in the environment, and data relating the expected position of the person in the environment to obtain an expected relative position of the person with respect to the medical device.

Disclosed herein are an X-ray detector having impact resistance, and an X-ray imaging apparatus including the same. An X-ray detector for detecting X-rays irradiated from an X-ray source includes a case having at least one opening and a sensing panel configured to convert the X-rays irradiated from the X-ray source into an electrical signal. A frame detachably inserted into the inside of the case through the at least one opening. The frame includes a body on which the sensing panel is disposed and a plurality of legs extending from the edges of the body in a first direction of the X-ray detector. A plurality of buffer members disposed between the plurality of legs and the case and in close contact with the plurality of legs and the case while surrounding a plurality of surfaces of each of the plurality of legs.

Disclosed is a C-shaped arm X-ray apparatus, comprising a C-shaped arm translation assembly (1), a support column (2), a base (3), a balancing weight (4) and an adjusting apparatus. One end of the support column (2) is connected to the base (3), and the other end of the support column is slidably connected to the C-shaped arm translation assembly (1). The balancing weight (4) is in sliding connection with the base (3). The adjusting apparatus is connected to the balancing weight (4), and when the C-shaped arm translation assembly (1) moves in a first direction, the adjusting apparatus enables the balancing weight (4) to move by a preset distance in the direction opposite to the first direction such that the gravity center of the C-shaped arm X-ray apparatus can be maintained at a preset position. The stability of the C-shaped arm X-ray apparatus can be guaranteed by adjusting the position of the balancing weight (4) by means of the adjusting apparatus.

A CPU acquires a distance image or a visible light image captured by a TOF camera or a visible light camera that has, as an imageable region, a region including an irradiation region which is a space in which a breast of a subject imaged by a mammography apparatus is irradiated with radiation emitted from a radiation source and detects whether or not a foreign object other than an object to be imaged is present in the irradiation region on the basis of the distance image or the visible light image.

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 device, as disclosed, may be suitable for use with a tomographic imager comprising an X-ray source and a plane detector that are movable in rotation. The device (e.g., radiopaque device) includes a registration phantom that includes several radiopaque markers and that is placeable along a part of the spine of a patient at a predetermined distance from a volume of interest to be imaged. Several radiopaque screens, integral with the registration phantom, include a lower face, an internal face oriented toward the registration phantom, and an external face oriented toward the X-ray source (410), respectively towards the detector. The radiopaque device is configured so that, when it is placed on the back of a patient, at least part of the X-rays that pass from the X-ray source to the plane detector through the registration phantom see their intensity attenuated by passing through the radiopaque screens.
