摘要： A co-registration system includes a processor circuit that generates and displays a first co-registration reliability indicator based on the status of an x-ray imaging device and a second co-registration reliability indicator based on the speed of an intravascular catheter/guidewire. The processor circuit receives, from the x-ray imaging device, x-ray images of a blood vessel while the intravascular catheter/guidewire moves through the blood vessel. The processor circuit receives, from the catheter/guidewire, intravascular data representative of the blood vessel while the catheter/guidewire moves through the blood vessel. The processor circuit co-registers the intravascular data to an x-ray image received from the x-ray imaging device. The processor circuit also receives a signal representative of an inactive status of the x-ray imaging device during the movement of the catheter/guidewire. The processor circuit then displays the first reliability indicator representative of the x-ray fluoroscopy device status and may indicate that co-registration is not possible. The processor circuit also determines a speed of the catheter/guidewire and displays a second indicator representative of the speed of the catheter/guidewire being too fast for reliable co-registration.

摘要： Systems and methods for ultrasound image acquisition, tracking and review are disclosed. The systems can include an ultrasound probe coupled with at least one tracking device configured to determine a position of the probe based on a combination of ultrasound image data and probe orientation data. The image data can be used to determine a physical reference point and superior-inferior probe coordinates within a patient being imaged, which can be supplemented with the probe orientation data to determine lateral coordinates of the probe. A graphical user interface can display imaging zones corresponding to a scan protocol, along with an imaging status of each zone based at least in part on the probe position. Ultrasound images acquired by the systems can be tagged with spatial indicators and severity indicators, after which the images can be stored for later retrieval and expert review.

摘要： A system (10) is for performing ECG measurements and comprises a probe (12) with an integrated one or more ECG electrodes (22) and an ultrasound sensing means (18), such as a transducer arrangement. The probe thus provides a mobile ECG electrode which can be sequentially moved between a set of different locations on the body for acquiring ECG measurements from different angles relative to the heart (i.e. different 'leads'). Positioning of the probe in each required location is guided by a position guidance function which uses ultrasound data acquired by the ultrasound sensing means to locate the probe (with reference to an ultrasound body atlas (28) or map), and uses a stored set of reference body locations to guide a user with guidance information as to how to move the probe to arrive at a next target electrode location. In examples, the user may be guided through a sequence of electrode locations, with ECG data acquired at each one, thereby sequentially building up a set of standard ECG lead measurements.
