  • Patent number: 9936896
    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.

  • Patent number: 9433746
    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.

  • Patent number: 8959753
    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 which allow more precise location identification of the catheter in the merging of 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.

  • Patent number: 5808427
    Abstract: In accordance with the present invention, an electric vehicle drive control system is provided. The system of the present invention controls the supply of actuating power to an electric motor for driving the vehicle. One preferred embodiment of the system permits a user to temporarily override a previously selected maximum power usage level for the motor so as to permit the amount of power supplied to the motor to be increased to a higher maximum power usage level.
