Abstract

Ultrasound images are adjusted according to the size of the display area available to display them, so that image detail is displayed with a large enough physical size to discern comfortably. A translation ratio is determined for translating the physical distance traversed by the ultrasound signals of an ultrasound images to a corresponding physical distance on a screen of the display device. If the ratio is not below a threshold, the image is displayed in full. If the ratio is below the threshold, the image is cropped, optionally scaled, and displayed in the available area. Scaling and cropping may be based on window size and threshold window size. The parameters of the ultrasound scan may be controlled based on the scaling, cropping, or available screen size. User interface features may be displayed on the screen depending on how much area is available when the image is displayed.

Dependent claims

A method for adapting display of an ultrasound image on a display device, the ultrasound image being generated from ultrasound signals transmitted and received by an ultrasound scanner, the method comprising:

determining a physical distance traversed by the ultrasound signals to generate the ultrasound image;
determining a translation ratio for translating the physical distance traversed by the ultrasound signals to a corresponding physical distance on a screen of the display device, were the ultrasound image be fitted to an available physical area of the screen of the display device;
if the determined translation ratio is less than a minimum threshold translation ratio,
generating a test ultrasound image at the minimum threshold translation ratio,
performing a cropping operation on the test ultrasound image to generate a cropped test ultrasound image, and
determining if the cropped test ultrasound image fits the available physical area of the screen of the display device;
if the cropped test ultrasound image does not fit the available physical area of the screen of the display device,
scaling the cropped test ultrasound image generated from the cropping operation so that the scaled and cropped test ultrasound image is fitted to the available physical area of the screen of the display device;
and
displaying the scaled and cropped test ultrasound image within the available physical area of the screen of the display device.

A computer readable medium comprising computer readable instructions which, when executed by a processor of a display device that is communicably coupled to an ultrasound scanner, configure the display device to:

determine a physical distance traversed by ultrasound signals that are transmitted and received by the ultrasound scanner to generate an ultrasound image;
determine a translation ratio for translating the physical distance traversed by the ultrasound signals to a corresponding physical distance on a screen of the display device, were the ultrasound image be fitted to an available physical area of the screen of the display device;
if the determined translation ratio is less than a minimum threshold translation ratio,
generate a test ultrasound image at the minimum threshold translation ratio,
perform a cropping operation on the test ultrasound image to generate a cropped test ultrasound image, and
determine if the cropped test ultrasound image fits the available physical area of the screen of the display device;
if the cropped test ultrasound image does not fit the available physical area of the screen of the display device,
scale the cropped test ultrasound image generated from the cropping operation so that the scaled and cropped test ultrasound image is fitted to the available physical area of the screen of the display device;
and
display the scaled and cropped test ultrasound image within the available physical area of the screen of the display device.
