Ultrasound Imaging - Fetal Biometry

The head of a fetus measured is shaped like an ellipse.

It’s used in the real world when mothers get an anatomy scan. The sonographer takes images of the fetal head in a transverse view.

The BPD is the minor axis, while the OFD is the major axis.

Surgeons often make elliptical incisions (most especially in skin lesions or removals) because this shape heals better and reduces scarring compared to circular cuts.

Surgeons often use an Elliptical Incision.when removing skin lesions, tumors, or cysts. This shape is chosen because An Ellipse is easier to close the skin neatly afterward

The lens of the eye is often described as elliptical in cross-section.

1) The lens of the eye is used by every human being that has an eye. The elliptical shape is important because it can affect how a person perceives depth and light.

2) We chose this image because we feel like it demonstrates the ellipse of an eye.

3) We can be inspired by the structure of the eye for future builds and projects.

Used by visually impaired patients

It resonates with us because we're both visually impaired and require glasses

Elliptic glasses meet the strand goals by using science to improve vision, eco-friendly materials to help the environment, and a creative design to make them useful and user-friendly.

This is an example of an ultrasound, which is used for diagnostic imaging and monitoring fetal development during pregnancy. As well as guide biopsies access blood flow and etc.

Ellipses are used for incisions since they allow for removing skin lesions cleanly with as little scarring and tension.

Lithotripsy is a medical procedure which uses shock waves in the properties of an ellipse to focus shock waves onto kidney stones to breakup them up

A real-world example of an ellipse in medicine is the cornea of the human eye. The cornea is not perfectly circular but its cross-section is slightly elliptical, with the horizontal diameter being longer than the vertical. This shape is important for properly focusing light onto the retina which allows us to see clearly.

We chose this example because it shows how biology uses the ellipse. The cornea’s elliptical shape helps scientists in fields like biotechnology, where contact lenses are designed. It also connects to design thinking because understanding natural shapes inspires designs for medical tools and technologies that better fit human anatomy.

Elliptical sound focusing helps direct sound waves to the ear more effectively. If the sound starts at the focus of ellipse, it will bounce and gather at the other focus, which can be directed to the ear.

This type of excision is often used in closing skin after a surgery or procedure. By doing this it promotes faster healing and less scars on a patients wound. We chose this because its an application of how we can apply pre-calculus in real life to improve peoples lives.

The lithotripter is used to shatter kidney stones for easier removal. Its elliptical shape, having the ray of energy originally from one focus, reflect to the other focus, where the kidney stone is located. This shows how ellipses are applied in medical technology, and reduces costs of surgery.

Modern Magnetic Resonance Imaging (MRI) devices frequently have an elliptical bore (opening) instead of a complete circle. This design enhances patient comfort by providing additional room around the shoulders and chest while retaining the powerful magnetic field required for imaging.

The elliptical shape of MRI machines contributes to SDG 3: Good Health and Well-Being by enhancing patient comfort, easing anxiety, and providing greater access to medical imaging. This design aids in early disease detection and promotes more inclusive healthcare.

Ellipses are used in the analysis of brain images, where they can be used to fit and align reference slices for image registration, as well as in the study of normal-appearing white matter (NAWM) in conditions like multiple sclerosis.

Your Mission

Find a real-world example of an ellipse and share it with the class!

Steps to Complete:

1. Research a real-world ellipse example (MEDICAL RELATED)

2. Find or create an image, video, or use AI to generate an illustration of your example

3. Create a post with:

A clear title naming your ellipse example

A brief explanation of how it’s used in the real world, why you choose such image, how this will address the strand goals (Biotechnology, Green Engineering, and Design Thinking)

Your image, video, or AI-generated illustration

Tips:

Be creative! Look beyond the obvious examples

Explain why the elliptical shape is important for your example

Make sure your image clearly shows the elliptical shape
