  • Patent number: 11547388
    Abstract: A fusion imaging system co-registers and fuses real time ultrasound images with reference images such as those produced by MRI or CT imaging. In an illustrated implementation, previously acquired CT or MRI or ultrasound images are loaded into the system. An ultrasound system is operated in conjunction with a tracking system so that the ultrasound probe and images can be spatially tracked. A computerized image processor registers the probe position with a reference image of the anatomy being scanned by the probe and determines whether the probe appears to be inside the skin line of the subject. If that is the case it is due to probe compression of the subject, and the reference image is modified to locate the skin line in the reference image in front of the ultrasound probe. The modified reference images can then be readily co-registered and fused with the ultrasound images produced by the probe.

  • Patent number: 11529194
    Abstract: The present invention relates to a system SY for determining a position of an RF transponder circuit RTC respective an ultrasound emitter unit UEU. The RF transponder circuit RTC emits RF signals that are modulated based on received ultrasound signals that are emitted or reflected by the ultrasound emitter unit UEU. The position of the RF transponder circuit RTC respective the ultrasound emitter unit UEU is determined based on a time difference ?T1 between the emission of an ultrasound signal by the ultrasound emitter unit UEU and the detection by the RF detector unit RFD of a corresponding modulation in the RF signal emitted or reflected by the RF transponder circuit (RTC).

  • Patent number: 11478159
    Abstract: In a method and magnetic resonance (MR) apparatus for pulse wave velocity (PWV) measurement along the aorta of a subject using MR imaging, a multislice cardio synchronized segmented ciné MR data acquisition sequence is optimized in order to enhance inflow representation in the slice images, in order to make the multislice MR data acquisition sequence viable for clinical uses, so as to acquire intensity-based MR data from two transverse slices spaced from each other along the descending aorta. The respective intensities of relevant pixels in at least two respective slice images are analyzed in order to identify the arrival of a pulse wave in the respective slices by the onset of flow enhancement in the slices, represented by intensity changes in the pixels. From the onset of flow enhancement in the respective slice images, PWV is calculated. An electronic signal representing the calculated PWV is then provided from a computer.

  • Patent number: 11259702
    Abstract: An optical coherence tomographic (OCT) system includes a sample arm, a reference arm and an OCT probe. The probe irradiates a bodily lumen and a fluid contained within the bodily lumen with light of a sample beam transmitted through a double-clad fiber (DCF). A first detector detects light of a reference beam and light reflected from the bodily lumen and propagated through the core of the DCF to generate OCT interference signals. Light backscattered by the bodily lumen and by the fluid contained in the bodily lumen is propagated through a cladding of the DCF and detected by a second detector to generate an intensity signal. A processor analyzes the intensity signal, and triggers a pullback of the probe and initiates recording of OCT images of the bodily lumen in response to the intensity the backscattered light reaching a predetermined threshold value.
