Methods and systems are provided for detecting patient motion during a diagnostic scan. In one example, a method for a medical imaging system includes obtaining output from one or more patient monitoring devices configured to monitor a patient before and during a diagnostic scan executed with the medical imaging system, receiving a request to initiate the diagnostic scan, tracking patient motion based on the output from the one or more patient monitoring devices, and initiating the diagnostic scan responsive to patient motion being below a threshold level.

An automatic method of categorizing the contact force of a catheter tip against a portion of a patient's heart based on motion of the catheter tip, the method comprising (a) capturing a series of 3D-coordinate data points of the catheter tip as a function of discrete times with a 3D medical imaging system, the 3D coordinates corresponding to an orthogonal 3-axis spatial coordinate system, (b) using a programmable computing system, computing a set of measures based on the series of 3D-coordinate data points, (c) categorizing each measure by a respective set of predetermined threshold values; and (d) combining the categorized measures to yield a relative quality of the contact force.

Systems and methods are described herein for tracking, localization or controlling an elongate instrument or other medical instrument in an image or patient.

The invention concerns a method for obtaining operating parameters for an x-ray CBCT imaging apparatus in view of acquiring a set of data of a patient's maxillofacial region. The method comprises: identifying a patient's maxillofacial first region of interest (ROI1), determining a height of a horizontal plane of said patient's maxillofacial first region of interest (ROI1) when the patient is in an occlusion position or bites a patient positioning accessory, acquiring through a slit-shaped collimator window a first set of data relative to said patient's maxillofacial first region of interest (ROI1) including the horizontal plane using x-ray CBCT imaging, reconstructing an axial CBCT slice comprising the horizontal plane based on the first set of data relative to the patient's maxillofacial first region of interest (ROI1), displaying the reconstructed axial CBCT slice of the patients maxillofacial first region of interest (ROI1) from the acquired first set of data, defining at least partially a second region of interest (ROI2) based on the displayed reconstructed axial CBCT slice of the patient's maxillofacial first region of interest (ROI1) and intersecting the latter, obtaining operating parameters for an x-ray CBCT imaging apparatus based on at least the defined second region of interest (ROI2) in view of acquiring a second set of data including the defined second region of interest (ROI2).

A method and apparatus for x-ray fluorescence measurement in object (1) are disclosed. The method includes (a) producing x-ray beam (2) using source device (10), wherein beam extends through object parallel to a first projection direction, (b) irradiating object with beam at scan positions in first projection plane, which are set by scanning device (20) such that source device and object are moved relative to one another, (c) detecting x-ray radiation emitted from object using detector array device (30) securely connected to source device and including spectrally selective detector elements (31) arranged to detect radiation, and stop lamellas (32) extending in radial directions relative to beam direction shielding detector elements from radiation scattered in object and arranged such that detector elements are able to detect radiation from all locations, and (d) processing detector signals to capture x-ray fluorescence of target particles in radiation and to localize target particles in object.

Systems are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The systems include a drill guide having a bone dislodging member adapted to create a pilot SI joint opening in the dysfunctional SI joint through an incision comprising a length no greater than 3.0 cm; portions of the pilot SI joint opening being disposed in the sacrum and ilium bone structures. The drill guide includes a tri-mode fixation system adapted to position and stabilize the drill guide during creation of the pilot SI joint opening in the dysfunctional SI joint and delivery of the SI joint prosthesis therein. The systems also include a SI joint prosthesis configured to be inserted into the pilot SI joint opening of the dysfunctional SI joint, a prosthesis deployment assembly configured to engage the SI joint prosthesis and advance the SI joint prosthesis into the dysfunctional SI joint, and a bone harvesting assembly adapted to extract and collect dislodge bone material from the bone dislodging member after creation of the pilot SI joint opening.

Disclosed herein is a system, comprising: a radiation source configured to cause emission of characteristic X-rays of a chemical element in a portion of a human body by generating and directing radiation to the portion; a first image sensor configured to capture a set of images of the portion using the characteristic X-rays; and a second image sensor configured to capture a set of tomograms using the radiation that has transmitted through the portion.

A radiation imaging system includes a radiation source and a notifying unit. The radiation source is for still image shooting and moving image shooting performed by the radiation imaging system to obtain image data of a subject. The notifying unit notifies whether a type of imaging to be performed is the still image shooting or the moving image shooting in a mode in which the type is instinctively recognizable by at least one of sense of sight, sense of hearing, and sense of touch.

A method for fluoroscopy energizes a radiation source to form a scout image on a detector and processes the scout image to determine and report a radiation field position with respect to a predetermined zone of the detector. The radiation source is energized for fluoroscopic imaging of a subject when the reported radiation field position is fully within the predetermined zone.

According to some implementations, a n medical interventional imaging device for monitoring an interventional procedure is described. The medical interventional imaging device includes a temporary data buffer configured to temporarily store medical interventional fluoroscopic image data, a signal processor configured to detect if an abnormal state occurs during an intervention and to record an instant at which the abnormal state has occurred, and a permanent data storage configured to permanently store at least a part of the medical interventional fluoroscopic image data stored temporarily before and/or at the recorded instant if the abnormal state is detected.
