Editing M-Mode ultrasound images for creating a figure in Powerpoint

TL;DR

Learn how to create a side-by-side comparison figure using cardiac ultrasound M-mode images with different scales.

Transcript

hello so we've got the situation where we want to create a figure using images from a cardiac ultrasound machine we've got cardiac ultrasound M mode images here taken on a visual Sonic Vivo 770 and you can see we've got an image at the top an image at the bottom the image at the top is looking fairly decent you can see the uh sepal wall and the the...

Key Insights

• 🤶 Two cardiac ultrasound M-mode images can be easily compared by creating a side-by-side figure with similar scales.
• 🥰 The scale differences in the images are due to changes in heart size and remodeling over time.
• ⚖️ Cropping, aligning, and adjusting the transparency and scale of one image can help create a visually comparable figure.
• 🤩 The use of the control key (or command key on Mac) and the shift key can aid in precise cropping and alignment.

Questions & Answers

Q: Why is it important to have the same scale when comparing two ultrasound images?

Having the same scale allows for direct visual comparison between the two images, making it easier to identify functional differences and changes over time.

Q: How can you ensure that the two ultrasound images have the same scale?

By cropping an area of interest from both images, aligning them, and adjusting the transparency, one image can be stretched or scaled to match the other and achieve uniformity.

Q: What should be done if a mistake is made during the cropping process?

Pressing the control key (or command key on Mac) while cropping allows for unrestricted cropping. If a mistake is made, the cropping can be undone and readjusted.

Q: How can the alignment and scale of the images be further refined?

Using the shift key while moving the images can constrain the movement to the horizontal axis, allowing for precise alignment. The scale can be adjusted until the images are perfectly aligned.

Summary & Key Takeaways

• The content discusses the process of creating a figure using two cardiac ultrasound M-mode images with different scales.

• The purpose is to visually compare the differences between the two images and highlight any functional changes.

• By cropping and aligning the images, adjusting transparency, and stretching one image to match the other, a scaled and aligned figure can be created.
