Abstract:
In order to perform precise time-gain control using a small manual setting device, one of two-dimensional coordinates of a position on a surface of a tablet pointer 215 which an external object touches is defined as a coordinate on a time axis, and the other as a coordinate on a gain axis; and the time gain is controlled based on the two-dimensional coordinates. In order to provide an ultrasonic imaging apparatus that responds to the requirement for both portability and versatility, the ultrasonic imaging apparatus comprises a portable imaging apparatus 100 comprising ultrasonic imaging means, and a support apparatus 500 which comprises supporting means for supporting extension of functions of the imaging apparatus, and which is electrically connected to and mechanically joined to the imaging apparatus so that it can be removably combined with the imaging apparatus.
Abstract:
A hand held ultrasonic instrument is provided in a portable unit which performs both B mode and Doppler imaging. The instrument includes a transducer array mounted in a hand-held enclosure, with an integrated circuit transceiver connected to the elements of the array for the reception of echo signals. A digital signal processing circuit performs both B mode and Doppler signal processing such as filtering, detection and Doppler estimation, as well as advanced functions such as assembly of multiple zone focused scanlines, synthetic aperture formation, depth dependent filtering, speckle reduction, flash suppression, and frame averaging.
Abstract:
An adjunctive ultrasound mammography system and associated methods are described in which an ultrasound image being displayed near an x-ray mammogram image may be superimposed thereon or thereunder by a user for facilitating rapid comprehension of breast structures and detection of abnormalities therein. In one preferred embodiment, the x-ray mammogram image corresponds to a standard x-ray mammogram view, and the ultrasound image is a thick-slice image representing a thick-slice or slab-like portion of the breast volume substantially parallel to that standard x-ray mammogram view. In another preferred embodiment, the user is permitted to manually manipulate the registration of the ultrasound image with the x-ray mammogram image. It has been found that the manual registration process, which involves manual vernier adjustments responsive to perceived registration differences, can rapidly increase the radiologist's perception of the breast structures being displayed by both component images. Even though ultrasound images tend to have substantially different textures and feature emphases than x-ray images, the bimodal thick-slice/x-ray image, alone or in conjunction with the vernier registration process, can often expose or clarify tissue structures hidden in the separate component images, and can often obviate or explain certain noticed structures in the component images.
Abstract:
Systems and methods of probing a material under investigation using an ultrasound beam. Echolocation data is generated using a multi-dimensional transform capable of using phase and magnitude information to distinguish echoes resulting from ultrasound beam components produced using different ultrasound transducers. Since the multi-dimensional transform does not depend on using receive or transmit beam lines, a multi-dimensional area can be imaged using a single ultrasound transmission. In some embodiments, this ability increases image frame rate and reduces the amount of ultrasound energy required to generate an image.
Abstract:
Ultrasound apparatus for examining tissue in a region of interest in a body comprising a housing having a viewing aperture. An ultrasonic transducer is provided comprised of an array of ultrasonic elements disposed in the viewing aperture. Electrical pulses are supplied to the transducer for transducer excitation to introduce ultrasonic signals into the body for reflection from the tissue in the region of interest. The transducer is capable of converting ultrasonic signals reflected from the tissue within the body to the transducer to provide electrical signals. The electrical signals are gain corrected in accordance with time. In-phase and out-of-phase components of the electrical signals are provided and then digitized. The digitized electrical signals are collected to form one image for a single frame of the tissue in the region of interest in the body from transducer excitations less than thirty-three in number which is then displayed.
Abstract:
A control panel for a diagnostic ultrasound system includes a keyboard with a wrist pad that stows beneath the control panel, and extends from the control panel when needed. The keyboard wrist pad integrates smoothly into the front of the control panel when the keyboard is in the stowed position. The keyboard wrist pad can also be integrated into the top surface of the edge of the control panel and can serve as a wrist pad for either the control panel or the keyboard when the keyboard is extended.
Abstract:
The control panel of an ultrasound system can swivel about the operator location. In one embodiment this capability is provided by pivoting the control panel about a pivot axis located forward of the center of the control panel, preferably within a few inches of the operator position. In another embodiment the control panel can be moved along a track which is curved about the operator position, and in a further embodiment the control panel is moved by a linkage which simultaneously moves the control panel from side to side and forward.
Abstract:
The present invention relates to a hand held ultrasound system having a balance body, a transducer assembly connected to said balance body via a communication means and a plurality of control elements arranged in an ergonomic fashion on said balance body, such that a user may hold said system and operate at least one of said control elements with the same hand. In particular a medical ultrasound system comprising a balance body incorporating system electronics, a power supply and a user interface wherein the user interface comprises a D-controller and a touch screen and a transducer assembly attached to the balanced body by a cable.
Abstract:
A cart-borne ultrasound system has a control panel at the front of the cart for operating the ultrasound system and a handle at the front of the cart by which a user can push or pull the cart to a different location. The handle has an opening through which a probe cable can be slipped to hang the cable over the handle during transport, storage, or use. The handle also serves to raise and lower the system control panel. The handle can also be articulated to move it out of the way of a user in front of the control panel.
Abstract:
A portable ultrasound system provides immersive viewing of images. A small, lightweight scope includes a transducer and a display. The display is adapted for viewing ultrasound images close to the eye of the user, such as within five inches or a couple feet of the eye. By adapting the system for close viewing, the ultrasound system is sensory inimersive, such as an otoscope or endoscope. A magnifying lens is positioned adjacent to a display screen. The magnifying lens adapts the small display screen for viewing close to the user's eye. A shade or eyepiece extends away from and at least partly around the display screen. The shade allows viewing in many different lighting conditions. Alternatively, the ultrasound image is viewed on a head mounted display attached to glasses or a helmet.
