A first set of pulses are delivered using at least one image sensor simultaneously with a second set of pulses delivered using at least one flow sensor disposed in an integrated interventional device towards a target region in a subject. Further, structural information corresponding to the target region at a designated time is determined using imaging signals received in response to the first sets of pulses. Additionally, volumetric information corresponding to the target region at the designated time is determined using signals received in response to the second sets of pulses. Moreover, the structural and volumetric information is processed using a determined model to compute one or more diagnostic parameters corresponding to the target region.

Method for minimally invasive medical intervention
InactiveUS20090287066A1Character and pattern recognitionDiagnostic recording/measuringPre-interventionFunctional imaging
A workflow for a minimally invasive intervention, such as a treatment for a cancerous tumor, includes positioning a patient at a multi-functional imaging apparatus, obtaining pre-interventional images of the anatomy of the patient using a computed tomography or angiography imaging function, performing the minimally invasive intervention while the patient is positioned at the multi-functional imaging apparatus and while using a fluoroscopic imaging function, and performing a post-interventional imaging of the patient's anatomy while the patient is positioned at the multi-functional imaging apparatus using the computed tomography or angiographic imaging function. If the post-interventional imaging determines that additional intervention is in order, the additional intervention is performed while the patient is positioned at the imaging apparatus. Pre-intervention images and data sets from other sources may be combined with or used during the intervention. A treatment planning step may be included following the pre-interventional imaging and the intervention.

Methods and systems for interventional imaging
Methods and systems for imaging a subject are presented. A series of volumetric images corresponding to a volume of interest in the subject is received during an interventional procedure. One or more of anatomical structures in at least one volumetric image selected from the series of volumetric images are detected. Detecting the anatomical structures includes determining an originally acquired view of the anatomical structures in the selected volumetric image. An optimal view of the anatomical structures is determined for performing a desired imaging task during the interventional procedure. The detected anatomical structures are automatically reoriented to transform the originally acquired view of the detected anatomical structures into a reoriented view. One or more obstructing structures are automatically removed from the reoriented view to generate the optimal view of the detected anatomical structures. The selected volumetric image including the optimal view of the detected anatomical structures is displayed in real-time.

Medical reporting apparatus
During a medical intervention such as an angiography, the X-ray examination equipment (such as that mounted on a C-arm) produces a very large number of imaging frames of the intervention, as it progresses. This information contains frame sequences which can be effectively used to improve a medical report of the intervention. The sequence will contain sequences which contain similar clinical information though, and these frames may be considered to be redundant and not useful for inclusion in the medical report. The aspects detailed herein enable a selection of non-redundant sequences and / or frames, based on contextual information, obtained from the sequence of images, and / or other medical equipment, during an intervention. In this way, the redundancy inherent in the original frame sequencecan be removed, leaving a set of prepared candidate sequences for insertion into a multimedia or documentary medical report.
