Filed:

Jan 12, 2012

Appl. No.:

13/349035

Inventors:

Wilko Gerwin Wilkening - Mountain View CA, US
Lex Garbini - El Granada CA, US
Ricardo Espinosa - Mountain House CA, US

Assignee:

Siemens Medical Solutions USA, Inc. - Malvern PA

International Classification:

A61B 6/00

US Classification:

600426

Abstract:

Registration is provided for imaging with an intra-patient probe. The intra-patient probe is used for imaging or the imaging is, at least in part, of the intra-patient probe. Either approach for imaging with an intra-patient probe uses active transitions for registration. In one embodiment, one or more markers in the intra-patient probe are moveable relative to the intra-patient probe, allowing avoidance of occlusions and providing more reliable marker detection for registration. In another embodiment, a value of a parameter for imaging with at least one modality is changed so that acceptable or better registration with an image of another modality may be made. The imaging is repeated with differences, such as field-of-view or scale, allowing for registration for different types of modalities.

US Classification:

29525, 29428, 29720, 29729

Abstract:

A catheter is provided for medical ultrasound imaging that can be effectively used in combination with other imaging modalities to detect medical structures of interest as well as the catheter. Markers are added to the catheter with precision, which provides a means to merge the images from different modalities. Using a template, apertures for marker placement are formed in the catheter after creating the catheter housing. The ultrasound array may be used for accurate positioning of the template. Alternatively or additionally, a rigid insert with markers connects with the array. The insert holds the markers in place and may reduce artifacts in ultrasound scanning due to flexing of the array.

International Classification:

A61B 800

US Classification:

600466

Abstract:

An apparatus and method for operating a catheter guiding assembly, with one lumen providing access for an ultrasound imaging catheter and a second lumen providing a working port for a tool. Optionally, the ultrasound imaging catheter in the catheter guiding assembly is exposed to blood, and the ultrasound imaging catheter port has a gasket. Alternatively, the catheter guiding assembly is sealed to prevent blood contact by the ultrasound imaging catheter, and the ultrasound imaging catheter may be re-used several times. In either case, the working tool is in the field of view of the ultrasound imaging catheter and normally exposed to blood. Because the working tool is exposed to blood, the working port has a gasket to keep blood from leaking out. Optionally, the working port is used for fluid delivery for injecting contrast agent, chemicals or drugs, which can be activated by sonification from the ultrasound imaging catheter.

International Classification:

A61B 800

US Classification:

600459

Abstract:

An ultrasonic transducer assembly includes a conduit that defines a lumen, and the lumen carries a flexible circuit. The flexible circuit can take several forms. In one form the circuit is folded at first and second fold lines, and at least one of the folds is oriented obliquely to the longitudinal axis of conduit. In another form the flexible circuit includes an end portion that defines a plurality of substantially parallel grooves, each groove aligned with and exposing a respective one of the conductors of the circuit. Additional conductors are positioned in respective ones of the grooves and are electrically connected with the respective conductors of the flexible circuit.
