First Claim
Patent Images
1. A touch-sensitive display device for a sonographic device, comprising:
- a user interface including a screen that displays a live sonographic image and at least a first virtual reference object, the user interface automatically scaling the first virtual reference object in proportion to the live sonographic image such that the scale between the live sonographic image and the virtual reference object remains 1;
1, wherein the first virtual reference object;
a) is selectable by touching the screen;
b) represents a medical instrument; and
c) is movable independent from the medical instrument.

Abstract
A user interface for a sonographic device is disclosed that displays a sonographic image and at least one reference object corresponding to a catheter size. The reference object may be scaled in proportion to the sonographic image. In addition, the user interface may further display a plurality of vertical lines and a plurality of horizontal lines arranged in a grid-like pattern and placed over the sonographic image. The size of both the sonographic image and the at least one reference object may change in proportion to a chosen insertion depth. A display device, a sonographic device and corresponding methods are also disclosed.

10. A method for selecting a size of a medical instrument, comprising:
-
displaying a live sonographic image of an internal structure of a body in a user interface; selecting a virtual reference object representing a medical instrument and being movable independent from the medical instrument; displaying the virtual reference object in the user interface; repositioning the virtual reference object to a desired location in the user interface; changing an insertion depth of the live sonographic image; and automatically scaling the virtual reference object in proportion to the live sonographic image such that the scale between the live sonographic image and the virtual reference object remains 1;
1 as the insertion depth changes. - View Dependent Claims (11, 12)

13. A software module including computer executable code located within a memory device that comprises at least one block of computer instructions to perform a method for facilitating selection of a size of a medical instrument, the method comprising:
-
displaying a live sonographic image of a vascular structure in a user interface; displaying a virtual reference object in the user interface, the virtual reference object representing a medical instrument of a selected size and being movable independent from the medical instrument; and automatically scaling the virtual reference object in proportion to the live sonographic image such that the scale between the live sonographic image and the virtual reference object remains 1;
1 to allow comparison of the virtual reference object to the vascular structure. - View Dependent Claims (14, 15, 16)

17. A sonographic system, comprising:
- a probe that transmits ultrasonic signals and receives reflected ultrasonic signals;
a housing including a display device, the display device comprising a user interface that displays a live sonographic image based on reflected ultrasonic signals received by the probe and at least a first virtual reference object, the first virtual reference object representing a medical instrument moveable independent from the medical instrument, the user interface automatically scaling the first virtual reference object in proportion to the sonographic image such that the scale between the live sonographic image and the virtual reference object remains 1;
1; and
a processor that controls the operation of the sonographic system. - View Dependent Claims (18)
