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.

A 3D X-ray device including an X-ray detector, an X-ray source and a computer. The X-ray detector and the X-ray source are moved about an object volume to be recorded on movement paths with a rotation of at least 185°. A number of X-ray projection images are recorded from different directions. X-rays irradiate the object volume in one of the irradiation directions and are captured by the detector. A 3D X-ray image of the object volume is calculated from the recorded X-ray projection images by a reconstruction method. The X-ray detector is arranged asymmetrically relative to a central axis through a center of rotation of the 3D X-ray device. A first fan beam and an opposite second fan beam rotated 180° form an overlap region. At least one X-ray filter is placed between the X-ray source and the object volume for attenuating an X-ray dose inside the overlap region.

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 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 radiotherapy system (220, 320) comprises a first rotary support apparatus (204, 304) configured to support a radiation beam source (200, 300) and to cause a radiation beam source (200, 300) to rotate about a rotation axis (218, 318, 518), a second rotary support apparatus (214, 314, 414, 514) and a radiation shield (202, 302, 402, 502) mounted to the second rotary support apparatus (214, 314, 414, 514). The second rotary support apparatus (214, 314, 414, 514) is configured to cause the radiation shield (202, 302, 402, 502) to rotate about the rotation axis (218, 318, 518).

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.

A paralleling device that attaches to or is integrated with the backscatter shield of a handheld x-ray device. The paralleling device includes a number of ports that receive a rod and hold the rod in a fixed position. The rod is attached to an electronic sensor for use in oral and dental radiography. By fixedly attaching the electronic sensor and rod to the handheld x-ray device, the paralleling device allows dentists, hygienists and other dental assistants to easily configure and place the rod and electronic sensor in the patient's mouth without setting the handheld x-ray device down. The paralleling device also ensures that the electronic sensor and handheld x-ray device are at an appropriate angle relative to one another to allow for proper imaging of a patient's mouth.

A medical imaging system for detecting ionizing radiation. The system includes one or more pixilated imagers positioned to acquire patient image data and one or more position sensors positioned to acquire patient position data. Once the patient image data and patient position data are acquired, one or more processors operably connected to each of the one or more pixilated imagers and one or more position sensors calculate a three-dimensional mass distribution based on patient image data and patient position data.

Syringe shield for using a syringe that includes a barrel, a tip and a plunger when manipulating a radioactive solution. The syringe shield includes: a shield body in which the syringe is insertable, the shield body having a window; a first flange at a first open end of the syringe shield; a second flange at a second open end of the syringe shield; wherein the second flange, the shield body, and the window include radiation shielding material, and wherein the tip of the syringe is accessible by the second open end of the syringe shield and the plunger extends outside the first open end when the syringe is inserted in the syringe shield.
