Organically responsive scrolling in ultrasonic diagnostic equipment
First Claim
1. Ultrasonic diagnostic equipment which beams ultrasonic emission in diagnostic sounding lines into an organism and, through processing echoed and scattered signals from said ultrasonic emission which are received by said equipment from within the organism, displays data pertaining to, the organism, said equipment comprising:
- a probe, said probe containing transducing means for generating said ultrasonic emission and beaming said ultrasonic emission into a portion of the organism under diagnosis, said transducing means also for detecting the ultrasonic signals echoed therefrom and scattered thereby;
transmit and receive means coupled to said probe, for transmitting transducing means actuation signals to said probe, and for processing said signals detected by said probe so as to obtain said data pertaining to said organism;
display means coupled to a video display monitor and said transmit and receive means, for continuous real-time display on said video display monitor of said data obtained by said transmit and receive means, wherein said display means scrolls the display at a scrolling speed corresponding to periodically elapsing changes in said data pertaining to said organism;
periodicity measuring means for measuring rate of a periodic organic function in connection with the portion of the organism under diagnosis; and
means for varying the scrolling speed in the display of said data according to the rate measured.

Abstract
Ultrasonic diagnostic equipment in which a probe beams ultrasonic waves into a living body under examination and detects reflected ultrasonic signals echoed or scattered therefrom. Data obtained from detected signals reflected from sounding lines of the ultrasonic emission are processed by a transmit and receive circuit or a Doppler detector to produce imaging data for M-mode display (corresponding to one radial or other line of a B-scan sweep) or for Doppler-mode display, on a video display monitor. The imaging data are written into a line memory driven by a 3 KHz clocking signal. In turn, the cycles of imaging data from the line memory are overwritten into a display memory via a clocking signal at a frequency selected by a display scrolling speed controller. The display scrolling speed controller, given an operator-selected display heartbeat number indicating how many heart beats is to be displayed per frame on the monitor, varies the speed at which recorded organic data are scrolled on screen according to the rate of periodicity of an organic function, e.g. of the heart, as measured by a measurement means. Scrolling-on of data in display is thus at a speed varying in synchronization with the rate of periodicity of the organic function so that data indicating and subject to the influence of periodic variance of the organic function in connection with examination is properly displayed as required for diagnosis.
