Abstract

A technique of framing a selected image area of a detector in a radiographic device is disclosed. The technique includes a user interface that is disposed on an outer surface of the detector. The user interface includes selectors that define a required image area or region of interest. For a clinical application, for example, mammography, the user interface selects only the required image area, and transmits the required image area further.

SELECTABLE REGION OF INTEREST (ROI) FOR A RADIOGRAPHIC DEVICE

BACKGROUND

The present invention relates generally to a radiographic device and more particularly to a technique for framing a selected image area of a detector in the radiographic device.

.

Generally, in a radiographic device, for example, in mammography, readout times are slow and at lower resolution due to transmission of an image area that is large. Consequently, frame rate is also less which affects image quality.

A conventional technique includes an X-ray diagnostic imaging system that includes a display for displaying live road-mapping image frame, and a user interface that allows a user to define and capture a small region of interest (ROI) in the displayed image frame for use by a processor that is conducting pixel shift calculation. The technique permits the ROI to be adjusted in size to achieve optimum performance and results. Another conventional technique includes selecting an augmented reality (AR) object on a head mounted device (HMD). The HMD defines a region of interest (ROI) based on a gesture formed by at least one hand of a user. Subsequently, the HMD displays to the user a shape on the HMD.

However, the above mentioned conventional techniques are not used for selecting ROI in the image area of the detector of the radiographic device.

 

It would be desirable to have a technique to select ROI in the image area of the detector of the radiographic device.

DETAILED DESCRIPTION

A technique of framing a selected image area of a detector in a radiographic device is disclosed. The technique includes a user interface that is disposed on an outer surface of the detector. The user interface includes selectors that define a required image area or region of interest. For a clinical application, for example, mammography, the user interface selects only the required image area, and transmits the required image area further. The required image area may be full resolution or binned. Consequently, frame rate and resolution of the image is optimized for the clinical application. Figure 1 depicts the user interface with selectors disposed on the outer surface of the detector.
