A method for automatic identification of a measurement item is provided. The method comprises acquiring, via an image acquisition module, gray values of pixels of a specified section image corresponding to ultrasonic echoes generated by reflection of ultrasound waves by a tissue under examination; identifying, via an identification module, at least one measurement item corresponding to the specified section image based on the gray values of the pixels; and measuring, via a measuring module, a measurement item parameter of the specified section image based on the measurement item identified. Because the measurement item of a specified section image can be automatically identified based on the content thereof, the user does not need to move a trackball to select measurement items, and therefore efficiency is increased.

Ultrasound systems having a computing device, a steering mechanism, and an ultrasound transducer are disclosed. The ultrasound transducer is configured to generate angularly discrete signals over a scan region of the ultrasound system in response to inputs from the steering mechanism. The computing device is communicatively coupled to the ultrasound transducer. The computing device includes a processor configured to receive angularly discrete ultrasound signals from the ultrasound transducer over the scan region, determine a scan line count corresponding to each of the received angularly discrete ultrasound signals, associate a TGC curve with each of the scan line counts, apply a TGC curve to each of the angularly discrete ultrasound signals as associated with the scan line count of each angularly discrete ultrasound signal, where each of the applied TGC curves defines a gain that maintains, increases, or decreases the angularly discrete ultrasound signal to which it is applied, over time.

An anatomical structure is detected (110) in a volume of ultrasound data by identifying (150) the anatomical structure in another volume of ultrasound data and generating (155) an image of the anatomical structure and an anatomical landmark. A group of images are generated (130) of the original volume and compared (140) to the image of the other volume. An image of the group of images is selected (150) as including the anatomical structure based on the comparison.

Disclosed are an ultrasound imaging system for analysis of a body composition and an operation method of an ultrasound imaging system which is designed for analysis of a body composition. An ultrasound imaging system may include: a scan device into which an object is insertable; an ultrasonic probe connected to a part of the scan device; a controller configured to control the ultrasonic probe to emit a transmission ultrasonic signal to the object at multiple positions at the scan device, and receive a reflection ultrasonic signal reflected from the object; and an image processor configured to generate multiple 2D ultrasound images based on reflection ultrasonic signals received at the multiple positions at the scan device, respectively, and generate a 3D ultrasound image based on the multiple 2D ultrasound images.

Provided is a non-invasive system and method of determining pennation angle and/or fascicle length based on image processing. An ultrasound scan image is processed to facilitate distinguishing of muscle fiber and tendon. The processed ultrasound scan image is then analyzed. The pennation angle and/or fascicle length is determined based on the analysis. An example method includes receiving an ultrasound scan image of at least a portion of a skin layer as disposed above one or more additional tissue layers, the image provided by a plurality of pixels. The method continues by introducing noise into the pixels of the image and thresholding the pixels of the image to provide a binary image having a plurality of structural elements of different sizes. The method continues with morphing the structural elements of the binary image to remove small structural elements and connect large structural elements. With this resulting image, the method distinguishes muscle fiber and tendon from remaining elements and determines the pennation angle and/or the fascicle length from the muscle fiber and the tendon. Associated apparatuses and computer program products are also disclosed.

An apparatus that detects a tip of an interventional tool based on at least two ultrasound images reconstructed for different beam steering angles within a volumetric region that includes the tool. The apparatus includes an image processor. The image processor includes a tip detection module used to perform a tip tool detection procedure. The tip tool detection procedure involves identifying shadow regions of the tool in the at least two ultrasound images and determining the position of the tip of the tool within the volumetric region.

The rotational intravascular ultrasound probe comprises an elongate catheter having a flexible body and an elongate transducer shaft disposed within the flexible body. The transducer shaft comprises a proximal end portion, a distal end portion, a drive shaft extending from the proximal end portion to the distal end portion, an ultrasonic transducer disposed near the distal end portion for obtaining a circumferential image through rotation, and a transducer housing molded to the drive shaft and the ultrasonic transducer.

An ultrasound diagnosis apparatus according to an embodiment includes processing circuitry.
