trasonic transducer array for transmitting a pulse-like ultrasonic wave to an object and detec- ting a reflection wave from the object, and as- suming the acoustic velocity of the object; a control arrangement for determining the depth of electronic focusing in accordance with this assumed acoustic velocity; and a display for dis- playing the assumed acoustic velocity. The ul- trasonic diagnosis system determines whether the reflection signal of the object at a pre- determined position is in-focus or out-of-focus and knows the actual acoustic velocity of the ob- ject from the assumed acoustic velocity when the reflection signal is in-focus.

FULLY WETTED MECHANICAL ULTRASOUND SCANHEAD

Dwayne H Putzke assigned to Advanced Tech- nology Laboratories Inc

A fully wetted ultrasound scanhead for medical applications is described in which the motor and the rotor are enclosed within a sealed housing fil- led with ultrasound coupling fluid. The inven- tion includes a drive belt to drive the rotor from the motor, rather than a precision drive means. Speed adjustment means, including an encoder disk mounted on the rotor, provide feedback for an electronic speed controller. Accordingly, the speed of the motor can be adjusted as a direct consequence of the actual speed of the rotor.

ULTRASONIC DIAGNOSTIC APPARATUS

Noriaki Endo, Tsuyoshi Yoshie, Tochigi, Japan assigned to Kabushiki Kaisha Toshiba

In a digital scan converter, a vector data gene- rator is provided. When the scanning mode is selected, the predetermined vector data adapted to the selected scanning mode is generated from the vector data generator. This vector data is temporarily stored and then used when the ac- tual scanning commences.

CONTACT AGENTS FOR ULTRASONIC IMAGING

Steven Feinstein

A method of ultrasonic imaging for use in medical procedures is disclosed. The method comprises injecting specifically defined micro- particles or sonicated microbubbles into an animal or human to thereby alter the acoustic properties of an area to be imaged, and then ul- trasonically scanning the area so as to obtain an image.

METHOD FOR RECORDING MEDICAL DATA IN TWO MODES

Jerom Drexler assigned to Drexler Technology Corporation

A laser beam scanner system records medical in- formation on a direct-read-after-write optical data storage strip. The strip is adhered to a medium containing a picture, such as X-ray pic- tures, CAT-scan pictures, ultrasonic or N M R images, or microscope photos of tissue samples. The strip may record information such as a description or diagnosis related to the picture for archival storage.
