SYSTEMS AND METHODS OF BODY MOTION MANAGEMENT DURING NON-INVASIVE IMAGING AND TREATMENT PROCEDURES
A non-invasive system for concurrent monitoring cardiac, respiration activity and other body motions from a patent support device integrated with biometric sensors. Such system can also predicate a motion state to enable/disable a medical imaging device or radiotherapy device during cancer and/or cardiac arrhythmias treatment.
Automated motion correction in PET imaging
Methods and systems for automated motion correction of nuclear images are disclosed. A method includes receiving a first set of imaging data including a plurality if annihilation events detected during an imaging period and generating a plurality of four-dimensional volumetric images from the imaging data for the imaging period. Each four-dimensional volumetric image includes a target tissue. At least one motion correction is determined for each of the plurality of four-dimensional volumetric images. The at least one motion correction is determined using target tracking data generated for the target tissue over a time period associated with the four-dimensional volumetric image. Corrected image data is generated from the first set of imaging data and the at least one motion correction and at least one static reconstruction image including the target tissue during the imaging period is generated from the corrected image data.
SYSTEM AND METHOD FOR MOTION GUIDANCE DURING MEDICAL IMAGE ACQUSITION
The present disclosure relates to systems and methods for monitoring and guiding patient motion during medical image acquisition. In accordance with certain embodiments, a method includes acquiring an image of a patient with an imaging system; determining an amount of patient movement; and providing a movement indicator based on the determined amount of patient movement.
SYSTEMS AND METHODS FOR ARTIFACT DETECTION FOR IMAGES
Systems and methods for obtaining images are described. A method may include detecting a patient residing on a table proximate the system and detecting one or more artifact areas within an anatomical scan range of the patient. In some examples, the method can include generating an artifact area indicator for the system to display, wherein the artifact area indicator comprises data indicating a location for each of the one or more artifact areas that reside within the anatomical scan range of the patient.
Medical device navigation system
A system for navigating a medical device is provided. In one embodiment, a magnetic field generator assembly generates a magnetic field. Position sensors on the medical device, on an imaging system and on the body generate signals indicative of the positions within the magnetic field. The generator assembly and reference sensors are arranged such that a correlation exists between them and the positions of the body and of a radiation emitter and a radiation detector of the imaging system. An electronic control unit (ECU) determines, responsive to signals generated by the sensors, a position of the medical device, a position of one of the radiation emitter and detector and a distance between the emitter and detector. Using this information, the ECU can, for example, register images from the imaging system in a coordinate system and superimpose an image of the device on the image from the imaging system.
MEDICAL INSTALLATION, AND METHOD FOR CONTROLLING A MEDICAL APPARATUS THEREIN
In a method to control a medical apparatus of an installation having: a contact device for a patient, at least one electrical potential sensor that can be coupled to the body of said patient is integrated into the contact device. A signal evaluation device is provided with measurement signals generated with the electrical potential sensor for evaluation. The medical apparatus is connected with the signal evaluation device, and measurement signals that relate to the breathing and/or cardiac activity of the patient are acquired with the at least one electrical potential sensor coupled to the body of said patient upon contact of the patient with the contact device. Trigger signals are generated with the signal evaluation device based on the measurement signals that relate to the breathing cycle and/or the cardiac cycle of the patient. Operation of the medical apparatus is controlled based on the trigger signals.
Extremity imaging apparatus for cone beam computed tomography
An apparatus for cone beam computed tomography can include a support structure, a scanner assembly coupled to the support structure for controlled movement in at least x, y and z orientations, the scanner assembly can include a DR detector configured to move along at least a portion of a detector path that extends at least partially around a scan volume with a distance D1 that is sufficiently long to allow the scan volume to be positioned within the detector path; a radiation source configured to move along at least a portion of a source path outside the detector path, the source path having a distance D2 greater than the distance D1, the distance D2 being sufficiently long to allow adequate radiation exposure of the scan volume for an image capture by the detector; and a first gap in the detector path.
Methods and systems for retrospective internal gating
The present invention, in one form, is a method for deriving respiratory gated PET image reconstruction from raw PET data. In reconstructing the respiratory gated images in accordance with the present invention, respiratory motion information derived from individual voxel signal fluctuations, is used in combination to create usable respiratory phase information. Employing this method allows the respiratory gated PET images to be reconstructed from PET data without the use of external hardware, and in a fully automated manner.
Quantification phantom for use with multiple imaging modalities
Described is an in-scan phantom for use during an imaging procedure. The phantom can include at least one measuring insert and/or at least one measured insert. The measuring insert may have radiation detecting capabilities while the measured insert may include a radioactive material. Also described is an imaging modality system that includes an imaging modality and an in-scan phantom as well as methods of using the in-scan phantom for imaging a patient or performing a scout scan.
COMBINED X-RAY SYSTEM AND PILOT TONE SYSTEM
Disclosed is an X-ray system (100, 700) configured for acquiring medical imaging data (134) from a subject (102) at least partially within an imaging zone (105). The X-ray system comprises a memory (128) storing machine executable instructions (130). The X-ray system further comprises a processor (122) configured for controlling the X-ray system. The X-ray system further comprises a pilot tone system (106), wherein the pilot tone 5 system comprises a radio frequency system (108) comprising multiple transmit channel (110) and multiple receive channel (112). The multiple transmit channel is configured for transmitting multiple pilot tone signal (136) via multiple transmit coil (114). The multiple receive channel is configured for receiving pilot tone data (138) via multiple receive coil (116). Execution of the machine executable instructions causes the processor to: transmit 10 (202) the multiple pilot tone signal by controlling the multiple transmit channel; acquire (204) the pilot tone data by controlling the multiple receive channel; and determine (206) a motion state (140, 700, 700′, 702, 702′) of the subject using the pilot tone data.
