A method for visualizing and targeting anatomical structures inside a patient utilizing a handheld screen device may include grasping the handheld screen device and manipulating a position of the handheld screen device relative to the patient. The handheld screen device may include a camera and a display. The method may also include orienting the camera on the handheld screen device relative to an anatomical feature of the patient by manipulating the position of the handheld screen device relative to the patient, capturing first image data of light reflecting from a surface of the anatomical feature with the camera on the handheld screen device, and comparing the first image data with a pre-operative 3-D image of the patient to determine a location of an anatomical structure located inside the patient and positioned relative to the anatomical feature of the patient.

An apparatus for Digital Imaging in the Head Region of a Patient includes an X-ray source and an X-ray sensor, supported on 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. A control unit, that controls the source, the sensor, the adjustment means, and the translation and rotation means Collision detection means provided in the source and sensor detect a possible collision of the source and/or sensor with the patient during the motion of the source and/or sensor and the control unit responds to such detected possible collision.

A mini C-arm with a movable X-ray source is disclosed. The mini C-arm including a moveable base, a C-arm assembly, and an arm assembly for coupling the C-arm assembly and the base. The C-arm assembly includes a first end, a second end, and a curved intermediate body portion defining an arc length. The source is positioned adjacent to the first end. A detector is positioned at the second end. The source is moveable along the arc length and relative to the detector to enable a plurality of images of the patient's anatomy to be acquired including a first image when the X-ray source is at a first position and a second image when the X-ray source is at a second position. The images being taken without moving the patient's anatomy. The C-arm assembly may include a motor and a belt drive system for moving the source relative to the detector.

Various embodiments discussed herein utilize a C-shaped imager to provide images with a minimal footprint, such as may be suitable in a surgical context. In addition the systems and methods described herein allow for suitable angular (i.e., azimuthal) scan coverage about the patient. To provide real-time 3D imaging, multiple X-ray tubes or a distributed X-ray source may be employed, coupled with an extended detector or multiple detectors. To reconstruct high-quality volumes, in some implementations reconstruction techniques may be employed that utilize pre-operative (pre-op) computed tomography (CT), magnetic resonance imaging (MRI), ultrasound (U/S), or other suitable modality images or data as prior information.

A radiography apparatus includes: an irradiation unit that emits radiation; an arm that can hold the irradiation unit and an image receiving unit in a facing posture; a first rotation mechanism that rotates the arm; and a friction mechanism that is switchable between a first state in which a frictional force is applied to the arm in a direction opposite to a direction in which the arm is rotated and a second state in which the frictional force applied to the arm is less than that in the first state.

Imaging systems and methods may facilitate positioning an imaging device in a procedure room. A 3D image of a subject may be obtained, where the subject is to have a procedure performed thereon. A view of the 3D image of the subject may be adjusted to a desired view and an associated 2D image reconstruction at the desired view may be obtained. A position for the imaging device that is associated with the desired view of the 3D image of the subject may be identified. Adjusting a view of the 3D image to a desired view and obtaining a 2D image reconstruction may be performed pre-procedure, such that a user may be able to create a list of desired views pre. A user may adjust a physical position of the imaging device to obtain reconstructed 2D preview images at the adjusted physical position of the imaging device prior to capturing an image.

A method for processing data relating to a radiological examination of a patient by way of a determining device, comprises the steps of acquiring doses (Ci, ti) measured at a plurality of times ti, storing these time-stamped measurements of radiation doses, and acquiring at least one DICOM digital file containing information on the examination, wherein the method comprises the following steps: acquiring and storing at least one DICOM digital file delivered by the tomograph during or after a tomography; acquiring and storing time-stamped measurements of the doses detected via a scintillating fiber placed on the table, and time-stamped movements of the table; interpolating the measurements (Ci, ti) with data of the image (DICOM) in a common interpolated space and constructing a table (Ck, DICOMk) in the interpolated space; and determining a table of the average dose levels Tz in each slice T depending on the data (DICOMk, Ck).

A system and method for navigating to a target using fluoroscopic-based three dimensional volumetric data generated from two dimensional fluoroscopic images, including a catheter guide assembly including a sensor, an electromagnetic field generator, a fluoroscopic imaging device to acquire a fluoroscopic video of a target area about a plurality of angles relative to the target area, and a computing device. The computing device is configured to receive previously acquired CT data, determine the location of the sensor based on the electromagnetic field generated by the electromagnetic field generator, generate a three dimensional rendering of the target area based on the acquired fluoroscopic video, receive a selection of the catheter guide assembly in the generated three dimensional rendering, and register the generated three dimensional rendering of the target area with the previously acquired CT data to correct the position of the catheter guide assembly.

A collision monitoring apparatus can include a camera to acquire a video image of surroundings of at least one target protection component on the C-arm X-ray machine system; an image processor to determine a scene of the surroundings of the at least one target protection component according to the video image; and a controller to control a C-arm X-ray machine system to stop moving or slow down when it is determined that a possible collision exists according to the scene of the surroundings of the at least one target protection component. Advantageously the apparatus effectively prevents patients, operators, patient examination beds and other obstacles from suffering a serious collision with the C-arm itself.
