User interface for handheld imaging devices

Abstract

A Graphical User Interface (GUI) for an ultrasound system. The ultrasound system has operational modes and the GUI has corresponding icons, tabs, and menu items image and information fields. The User Interface (UI) provides several types of graphical elements with intelligent behavior, such as being context sensitive and adaptive, called active objects, for example, tabs, menus, icons, windows of user interaction and data display and an alphanumeric keyboard. In addition the UI may also be voice activated. The UI further provides for a touchscreen for direct selection of displayed active objects. In an embodiment, the UI is for a medical ultrasound handheld imaging instrument. The UI provides a limited set of hard and soft keys with adaptive functionality that can be used with only one hand and potentially with only one thumb.

AI Technical Summary

Benefits of technology

[0017] The imaging device of the invention may provide for a microphone (and / or an input for an external microphone) and a loudspeaker (and / or an output for external loudspeakers). The user can train the device to recognize a set of words or combinations of words. Each recognizable unit (word or word combination) can be assigned to a device command, performing a specific function or a sequence of functions, so that the user has the option of operating part of or all of the ultrasound system by voice, thereby requiring less use of hands to operate.

[0020] In an embodiment, one-handed, potentially one-thumb alphanumeric data entry (e.g., patient name and / or other patient information) may be achieved by displaying a “virtual” keyboard. The user can select any alphanumeric key on the keyboard by using the left / right and up / down buttons. Using these buttons will have the same effect as depressing a keyboard key.

[0024] In an embodiment, in order to minimize the time for setting up and configuring the system the user interface may provide for application and / or user dependent presets, which are optimized based on several factors (e.g., user behavior, image quality, etc.). In an embodiment, several active elements are introduced in accordance with this invention in order to minimize user interaction for achieving predefined goals. For example, the icon “Full Screen Image” allows the user to directly switch to an imaging mode where the image occupies the full screen. The “Full Screen Image” display mode introduced in this invention is preferred because it shows the user a bigger image, where the details are easier to distinguish.

Problems solved by technology

Unwanted reflections within the ultrasound device can cause noise and the appearance of artifacts (i.e., image features that result from the imaging system and not from the medium under investigation) in the image.

Artifacts may obscure the underlying image of the medium under investigation.

In some cases, the user interfaces are cumbersome to operate.

Even more cumbersome are those user interfaces requiring two hands to operate or transport resulting in encumbrance of using the system for real-time examinations.

Other examples of difficulties that arise in the case of a handheld device are navigation and selection of the user interface items using one hand or one thumb.

Further, as medical services tend to be expensive, the easier a medical professional can operate the user interface, the more patients the medical professional can serve and the less the medical professional will need to charge for their services.
