In one aspect, matching layers for an ultrasonic transducer stack having a matching layer comprising a matrix material loaded with a plurality of micron-sized and nano-sized particles. In another aspect, the matrix material is loaded with a plurality of heavy and light particles. In another aspect, an ultrasound transducer stack comprises a piezoelectric layer and at least one matching layer. In one aspect, the matching layer comprises a composite material comprising a matrix material loaded with a plurality of micron-sized and nano-sized particles. In a further aspect, the composite material can also comprise a matrix material loaded with a plurality of heavy and light particles. In a further aspect, a matching layer can also comprise cyanoacrylate.

A system for acquiring an ultrasound signal comprises a signal processing unit adapted for acquiring a received ultrasound signal from an ultrasound transducer having a plurality of elements. The system is adapted to receive ultrasound signals having a frequency of at least 20 megahertz (MHz) with a transducer having a field of view of at least 5.0 millimeters (mm) at a frame rate of at least 20 frames per second (fps). The signal processing can further produce an ultrasound image from the acquired ultrasound signal. The transducer can be a linear array transducer, a phased array transducer, a two-dimensional (2-D) array transducer, or a curved array transducer.

High frequency array ultrasound system

A system for producing an ultrasound image comprises a scan head having a transducer capable of generating ultrasound energy at a frequency of at least 20 megahertz (MHz), and a processor for receiving ultrasound energy and for generating an ultrasound image at a frame rate of at least 15 frames per second (fps).

High frequency, high frame-rate ultrasound imaging system

A method of creating an image difference overlay comprises identifying a loop of reference images of a subject and identifying a loop of data images of the subject. The loop of image data can be identified after an event, such as the administration of contrast agent to the subject. A reference loop image frame is compared to one or more data loop image frames and the reference loop frame is associated with a data loop image frame which closely resembles the data loop image frame. Each of the associated frames can then be processed and used to create an image difference overlay frame.

Ultrasonic matching layer and transducer

A method for producing an ultrasound image comprises monitoring the subject's respiration cycle or waveform, acquiring ultrasound data from the subject, producing an ultrasound image from the received ultrasound data received during the time when the subject's motion due to breathing had substantially stopped.

Method for synchronization of breathing signal with the capture of ultrasound data

The small-animal mount assembly of the present invention can include a table member suitable for mounting a small animal. The table member can be selectively positionable into a desired table plane and can comprise at least one ECG pad and/or at least one grid of electronic heating elements disposed onto a top surface of the table pad. The assembly can also include a control apparatus electrically coupled to the at least one ECG pad and/or the at least one grid of electronic heating elements.
