A new technique of imaging: OPT

Mid-gestation mouse embryo

The new technique of Optical Projection Tomography (OPT) helps to reveal the internal structures of stained whole embryos and small pieces of tissue without the need for cutting sections. The mouse embryo shown here has been stained to show parts of the nervous system in green, the floor of the spinal cord and other tissue in blue and the heart in red. Unstained tissue appears grey. The OPT technique enables different elements of the staining patterns to be revealed in more detail using the computer to selectively remove overlying tissue. This process can be observed in the accompanying on-screen animation.

Radiotherapy video

This video shows the method of treating cancers with radiotherapy. It shows the equipment they use and answers some of the questions patients would have before they are treated.

Scans of the brain

This video is an interesting explanation of different techniques of imaging the brain.

Another endoscopy video

This endoscopy video shows the view from an endoscope. My daughter tells me it is gross. Not for the faint-hearted!

Endoscopy video

This is a very simple video such as the ones being used on medical websites to explain the endoscopic procedure to patients who are about to have one.

Ultrasound of a baby in the womb

I thought that this video was fantastic – a view of someone’s unborn baby.

Video about production of X-rays

This is a very interesting (but fairly long) video explain the history of X-ray discovery and the way in which the equipment was designed.

Hello!

I have written this blog to help you with your medical physics section while I am on camp. You will be working in your home groups on Tuesday to explain to the other members of your group the topic you learnt in your expert group. You must provide notes of the section for them. You will be handing those notes in to me by e-mailing them or giving them to the teacher who is with you. The page on this blog entitled More Information might help.

On Wednesday you will be working on your role play. You might like to have a look at the page Medical Physics in Context on this blog to help with this.

The information from the two pages on this blog is from a CD called “innovative physics” that was distributed by VCAA. The videos on the blog are from you-tube.

On Thursday, you will be working on the worksheets attached to this post. We will watch the role plays and discuss any problems next week. You will be sitting a test on this section on March 19th.

If you finish all of the above, have a look at some of the past exam papers on Learning Point and try the Medical Physics parts!

 Good luck and enjoy! Although I won’t be able to view your comments until I get back to the real world of the www, feel free to let me know whether this blog was useful and leave comments about problems or ideas you may have that the other students in your class might be able to help you with, or get help from.

Here, once again, are the documents outlining your task:
