An X-ray CT apparatus of an embodiment acquires projection data of a subject based on X-ray detection data according to biometric information synchronous scanning and generates a CT image of the subject based on the projection data. The X-ray CT apparatus includes a first acquisition unit, a determination unit, and a second acquisition unit. The first acquisition unit acquires biometric information of the subject at a timing when the biometric information synchronous scanning has been performed. The determination unit determines, as priority data, detection data that is a target for which data transfer will be preferentially performed among X-ray detection data acquired in the biometric information synchronous scanning based on the biometric information. The second acquisition unit acquires the priority data from a storage device that holds the detection data.

A panoramic X-ray imaging apparatus includes: an X-ray generating unit; an X-ray detecting unit; a support that supports the X-ray generating unit and the X-ray detecting unit; a drive mechanism that turns at least the X-ray generating unit and the X-ray detecting unit by driving the support; a displacement mechanism that adds movement including a displacement component in a direction different from the turning to the X-ray detecting unit; a subject holding unit that holds an imaging subject; a turning controller that controls the turning by a drive mechanism and the displacement mechanism. The turning controller controls the drive mechanism and the displacement mechanism so as to add the movement avoiding the contact with the shoulder of the imaging subject during the turning of the X-ray generating unit and the X-ray detecting unit by the drive mechanism during the panoramic X-ray imaging.

A method of sequential monoscopic tracking is described. The method includes generating a plurality of projections of an internal target region within a body of a patient, the plurality of projections comprising projection data about a position of an internal target region of the patient. The method further includes generating external positional data about external motion of the body of the patient using one or more external sensors. The method further includes generating, by a processing device, a correlation model between the projection data and the external positional data by fitting the plurality of projections of the internal target region to the external positional data. The method further includes estimating the position of the internal target region at a later time using the correlation model.

A phantom, phantom system, and method of phantom identification include a first material that forms a phantom. A phantom identifier includes at least one unit marker. The at least one unit marker identifies a physical characteristic of the phantom. In a method of phantom identification, an image of the phantom is obtained that includes the phantom identifier. The at least one unit marker is identified, the at least one unit marker encodes a value representative of a physical characteristic of the phantom.

Systems and methods are provided for delivering images to a patient before and/or during a medical procedure in which a patient is translated on a table relative to a gantry. In various example embodiments, images are projected to the patient while preserving the projected field size during table motion, thereby potentially reducing patient anxiety by providing a more immersive patient viewing experience. In some example embodiments, the projected field size is maintained by a display system that is secured to the table such that both a projector and a projection screen are fixed relative to the table, and relative to the patient, during translation of the table. In some example embodiments, a reduction in patient anxiety may be achieved by projecting images as virtual images that are perceived by the patient as residing at a depth that lies beyond the confined spatial region in which the patient resides.

A computed tomography device comprises: a gantry with an opening and a radiation protection apparatus configured to cover the opening, wherein the opening is configured to receive an examination object introduced into the opening along a system axis of the gantry; wherein the radiation protection apparatus has a radiation protection curtain, a curtain mounting and a pivot apparatus; wherein the curtain mounting has a bar-shaped area; wherein an upper edge of the radiation protection curtain is attached to the bar-shaped area such that the radiation protection curtain is stretched along the bar-shaped area and hangs down from the bar-shaped area; and wherein the curtain mounting is pivotably supported relative to the gantry about a pivot axis via the pivot apparatus.

The computed tomography device has a gantry with an opening and a radiation protection apparatus for covering the opening. The radiation protection apparatus includes a radiation protection cover and a pivoting apparatus, wherein an object under examination may be inserted into the opening along a system axis of the gantry when the radiation protection cover is in a first position relative to the gantry. The radiation protection cover is pivotably mounted relative to the gantry about a pivot axis by the pivoting apparatus such that a first pivoting motion of the radiation protection cover about the pivot axis enables the radiation protection cover to be lowered relative to the gantry from the first position to a second position. The computed tomography device may furthermore include at least one of a lighting system or a camera system.

A mobile computed tomography system has a gantry with an opening for at least partially accommodating a patient, and a carriage configured to be moved over a substrate with motor assistance.
