Methods and apparatuses for collection of ultrasound images
Aspects of the technology described herein include determining, during ultrasound imaging, that an anatomical region is clipped by a field of view of an ultrasound image, and providing a notification, during the ultrasound imaging, that the anatomical region is clipped by the field of view of the ultrasound image. Aspects of the technology described herein also include determining that an anatomical region is clipped by a field of view of at least one ultrasound image collected during a three-dimensional ultrasound imaging sweep, and providing a notification that the anatomical region is clipped by the field of view of the at least one ultrasound image collected during the three-dimensional ultrasound imaging sweep.
1. An apparatus, comprising:
a processing device comprising a processor and a display screen configured to display a graphical user interface (GUI), the processing device being in operative communication with an ultrasound device, wherein
the processing device is configured to:
display, during ultrasound imaging, an ultrasound image on the GUI on the display screen;
determine, during the ultrasound imaging and using a statistical model, a location of a specific point on an anatomical region shown in the ultrasound image at which to display an indicator; and
determine, during ultrasound imaging, whether or not the anatomical region shown in the ultrasound image displayed on the GUI on the display screen is clipped by a field of view of the ultrasound image,
wherein when determining whether or not the anatomical region shown in the ultrasound image is clipped by the field of view of the ultrasound image, the processor:
determines a modified field of view that is offset from edges of the field of view toward the center of the field of view;
determines a number of pixels of the anatomical region that are between the edges of the field view and edges of the modified field of view;
determines the anatomical region shown in the ultrasound image is clipped by the field of view of the ultrasound image when the number of pixels exceeds a threshold number of pixels; and
determines the anatomical region shown in the ultrasound image is not clipped by the field of view of the ultrasound image when the number of pixels does not exceed a threshold number of pixels;
wherein, in response to determining that the anatomical region shown in the ultrasound image is clipped by the field of view of the ultrasound image, the processing device is further configured to display, via the GUI, the indicator with a first aspect at the determined location and superimposed on the ultrasound image; and
wherein, in response to determining that the anatomical region shown in the ultrasound image is not clipped by the field of view of the ultrasound image, the processing device is further configured to display, via the GUI, the indicator with a second aspect at the determined location and superimposed on the ultrasound image.
2. The apparatus of claim 1 , wherein
the statistical model is trained to automatically determine the location of the specific point on the anatomical region shown in the ultrasound image at which to display the indicator.
3. The apparatus of claim 1 , wherein
the processing device is configured, when determining, during the ultrasound imaging, whether or not the anatomical region shown in the ultrasound image is clipped by the field of view of the ultrasound image, to determine that the anatomical region is clipped by the field of view of the ultrasound image in a time period between display of a previous ultrasound image and display of a subsequent ultrasound image.
4. The apparatus of claim 1 , wherein
the processing device is configured to display a measurement of a volume of the anatomical region.
5. The apparatus of claim 1 , wherein
the specific point has predetermined mathematical characteristics.
6. The apparatus of claim 1 , wherein
the processing device is configured to display the indicator in a time period between display of a previous ultrasound image and display of a subsequent ultrasound image.
7. The apparatus of claim 1 , wherein
the anatomical region comprises a bladder.
8. The apparatus of claim 3 , wherein
consecutive ultrasound images are displayed with a frame rate between 15-30 frames/second.
9. The apparatus of claim 4 , wherein
the processing device is configured to display a second indicator indicating whether the measurement of the volume of the anatomical region is accurate.
10. The apparatus of claim 9 , wherein
the second indicator comprises a symbol or text.
11. The apparatus of claim 5 , wherein
the specific point includes a centroid of the anatomical region.
12. The apparatus of claim 6 , wherein
consecutive ultrasound images are displayed with a frame rate between 15-30 frames/second.
13. An apparatus, comprising:
a processing device comprising a processor and a display screen configured to display a graphical user interface (GUI), the processing device being in operative communication with an ultrasound device, wherein
the processing device is configured to:
display, during a three-dimensional ultrasound imaging sweep, at least one ultrasound image;
determine, during the three-dimensional ultrasound imaging sweep and using a statistical model, a location of a specific point on an anatomical region shown in the at least one ultrasound image at which to display an indicator; and
determine whether or not the anatomical region shown in the at least one ultrasound image is clipped by a field of view of the at least one ultrasound image collected during the three-dimensional ultrasound imaging sweep,
wherein when determining whether or not the anatomical region shown in the at least one ultrasound image is clipped by the field of view of the at least one ultrasound image collected during the three-dimensional ultrasound imaging sweep, the processor:
determines a modified field of view that is offset from edges of the field of view toward the center of the field of view;
determines a number of pixels of the anatomical region that are between the edges of the field of view and edges of the modified field of view;
determines the anatomical region shown in the at least one ultrasound image is clipped by the field of view of the at least one ultrasound image collected during the three-dimensional ultrasound imaging sweep when the number of pixels exceeds a threshold number of pixels; and
determines the anatomical region shown in the at least one ultrasound image is not clipped by the field of view of the at least one ultrasound image collected during the three-dimensional ultrasound imaging sweep when the number of pixels does not exceed a threshold number of pixels;
wherein, in response to determining that the anatomical region shown in the at least one ultrasound image is clipped by the field of view of the at least one ultrasound image collected during the three-dimensional ultrasound imaging sweep, the processing device is further configured to display, via the GUI, the indicator with a first aspect at the determined location and superimposed on the at least one ultrasound image; and
wherein, in response to determining that the anatomical region shown in the at least one ultrasound image is not clipped by the field of view of the at least one ultrasound image collected during the three-dimensional ultrasound imaging sweep, the processing device is further configured to display, via the GUI, the indicator with a second aspect at the determined location and superimposed on the at least one ultrasound image.
