A system for providing navigational guidance to a sonographer acquiring images is disclosed. The system may provide haptic feedback to the sonographer. The haptic feedback may be provided through an ultrasonic probe or a separate device. Haptic feedback may include vibrations or other sensations provided to the sonographer. The system may analyze acquired images and determine the location of acquisition and compare it to a desired image and a location for obtaining the desired image. The system may calculate the location for obtaining the desired image based, at least in part, on the acquired image. The system may then provide the haptic feedback to guide the sonographer to move the ultrasonic probe to the location to acquire the desired image.

Haptic feedback for ultrasound image acquisition

An ultrasonic imaging system produces more diagnostic cardiac images of the left ventricle by plotting the longitudinal medial axis of the chamber between the apex and mitral valve plane as a curved line evenly spaced between the opposite walls of the myocardium. Transverse image planes are positioned orthogonal to the curved medial axis with control points positioned in the short axis view on lines evenly spaced around and emanating from the medial axis. If the short axis view is of an oval shaped chamber the transverse image is stretched to give the heart a more rounded appearance resulting in better positioning of editing control points.

Ultrasonic cardiac assessment of hearts with medial axis curvature and transverse eccentricity

An ultrasonic diagnostic imaging system has a user control by which a user positions the user's selection of a heart chamber border in relation to two myocardial boundaries identified by a deformable heart model. The user's border is positioned by a single degree of freedom control which positions the border as a function of a single user-determined value. This overcomes the vagaries of machine-drawn borders and their mixed acceptance by clinicians, who can now create repeatably-drawn borders and exchange the control value for use by others to obtain the same results.

The haptic feedback may be provided through an ultrasonic probe or a separate device. Haptic feedback may include vibrations or other sensations provided to the sonographer. The system may analyze acquired images and determine the location of acquisition and compare it to a desired image based, at least in part, on the acquired image. The system may then provide the haptic feedback to guide the sonographer to move the ultrasonic probe to the location to acquire the desired image.

An imaging system includes an imaging device () configured to acquire an image in a multi-beat acquisition mode. A quality scoring module () is stored in memory and is configured to evaluate changes in the image between portions of a multi-beat cycle to compute a quality score () indicating a suitability of the image. A display () is included for viewing the image and displaying the quality score as real-time feedback for the image.

Quality metric for multi-beat echocardiographic acquisitions for immediate user feedback

An ultrasonic diagnostic imaging system and method enable the automatic acquisition of standard view planes of the heart in real time, such as the AP4, AP3, and AP2 views. A 3D image of the heart is acquired and the processed in conjunction with a geometrical heart model. The heart model is fitted to the heart in its acquired pose to segment the desired image planes from the 3D image data. During successive image acquisition intervals the image planes are tracked through successive image data as a multi-plane system to update a display of the multiple images. The successive image acquisitions can be volume image acquisitions or multi-plane acquisitions of just the tracked image planes during each acquisition interval.

Automated segmentation of tri-plane images for real time ultrasonic imaging

An ultrasonic diagnostic imaging system is gated to acquire images at different phases of a physiological cycle such as the heartbeat. At each successive heart cycle a trigger actuates the acquisition of a continuous sequence of images, starting at a particular phase of the heart cycle and ending when the next heart cycle begins. Multiple triggers are used, each starting at a different phase of the heart cycle and each acquiring images at uniform temporal spacing. After the first trigger is used a sequence of images has been captured which are temporally evenly spaced over the heart cycle, and as successive triggers are used uniform temporal spacing is maintained as the heart cycle is filled in with additional images for replay of an image loop of phase re-ordered images at a high frame rate of display.
