Patent number: 11344282Abstract: An ultrasound system performs duplex colorflow and spectral Doppler imaging, with the spectral Doppler interrogation performed at a sample volume location shown on the colorflow image. The colorflow image is displayed in a color box overlaid on a co-registered B mode image. A color box position and steering angle processor analyzes the spatial Doppler data and automatically sets the color box angle and location over a blood vessel for optimal Doppler sensitivity and accuracy. The processor may also automatically set the flow angle correction cursor in alignment with the direction of flow. In a preferred embodiment these optimization adjustments are made automatically and continuously as a user pauses at points for Doppler measurements along a length of the blood vessel.Type: GrantFiled: September 14, 2018Date of Patent: May 31, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Ashraf Saad, Thanasis Loupas, David Hull, Steven John Hill

Patent number: 10368844Abstract: An ultrasound system with a matrix array (500) probe (10) operable in the biplane mode is used to assess stenosis of a blood vessel by simultaneously displaying two color Doppler biplane images (60a, 60b) of the vessel, one a longitudinal cross-sectional view (60a) and the other a transverse cross-sectional view (60b). The two image planes intersect along a Doppler beam line (68) used for PW Doppler. A sample volume graphic (SV) is positioned over the blood vessel at the peak velocity location in one image, then positioned over the blood vessel at the peak velocity location in the other image. As the sample volume location is moved in one image, the plane and/or sample volume location of the other image is adjusted correspondingly. Spectral Doppler data (62) is then acquired and displayed from the sample volume location.Type: GrantFiled: September 27, 2013Date of Patent: August 6, 2019Assignee: Koninklijke Philips N.V.Inventors: James Robertson Jago, Keith William Johnson, Ashraf Saad, David Allen Hull

Publication number: 20090076384Abstract: An analysis feature of an ultrasonic diagnostic system contains one or more exam protocols which guide a sonographer in carrying out one or more standardized ultrasound exams. During the conduct of an exam protocol template protocol steps are available. The sonographer can augment the standard protocol by selecting one of these template protocol steps and giving it a unique name for the current protocol. The execution of this added step will automatically invoke the diagnostic tools, such as measurements and calculations, which are inherent in the cloned conventional protocol step. In addition, the sonographer can add other diagnostic tools to the added step. The results of the standard and customized protocol steps are automatically recorded in the proper sequence and context of an automatically produced diagnostic report.Type: ApplicationFiled: October 3, 2005Publication date: March 19, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Ashraf Saad, Dan Skyba

Publication number: 20080188746Abstract: A method for automatic gain adjustment in spectral (pulsed wave—PW, and/or continuous wave—CW) Doppler for medical ultrasound includes separating a two-dimensional (2D) array of spectral levels (spectrogram) to be analyzed into signal and noise subsets. For each of the signal and noise subsets, a delta gain is calculated for achieving a predetermined display-based design specification. Subsequently, the separate signal and noise delta gains are combined into a single delta gain value, which is then applied to subsequent spectral Doppler signals or the spectrogram data stored in image memory, depending on whether the spectral Doppler mode is in a live or frozen state.Type: ApplicationFiled: March 2, 2006Publication date: August 7, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Thanasis Loupas, Ashraf A.

Publication number: 20080039725Abstract: An ultrasonic diagnostic imaging system produces a spectral Doppler display on which a parameter such as peak or mean velocity is automatically traced. If the user is dissatisfied with the automatically drawn trace (30), the user can manipulate a cursor (88) on the display screen to grab a point (82, 86) on the trace and drag the trace to a new location relative to the spectral display or manually redraw a portion of the trace. In an illustrated embodiment the spectral Doppler trace (80) includes defined key timing points in the heart cycle which can be adjusted by the user in both the velocity and time dimensions of the display. Graphically displayed values and calculations of the display are automatically updated in response to adjustment of the trace.Type: ApplicationFiled: August 1, 2005Publication date: February 14, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Junzheng Man, Haiyuan Lu, Marshall Robinson, Ashraf Saad, Dan Skyba
