So I want to also talk about a few valuable resources one can use
0:05
to further understand the CT physics.
0:07
Here is one of them, which is a book which I wrote a few
0:11
years ago. This is called the MDCT Physics, the Basic Technology,
0:15
Image Quality, and Radiation Dose.
0:17
There are several other resources,
0:20
such as task group report of the AAPM.
0:23
And one of the aspects which I also highlight is the American Association of
0:27
Physicists in Medicine maintain a protocol page
0:31
where anybody, even a non-AAPM member, can obtain.
0:34
And these protocols are developed based on a
0:38
consensus from all the vendors of each respective vendors,
0:42
how their scanner can recommend it to you to set the
0:46
protocol.
0:47
There's also another resource, very valuable resource for the residents is the
0:51
radiologyinfo.org. This is one of the
0:55
website developed by the cooperation of RSNA
0:59
and ACR, and it has a lot of information, very much
1:03
patient-friendly. And there's also a section on safety and
1:07
radiation dose, which I encourage any viewers to see.
1:11
There are other social media campaign, such as Image Gently and Image
1:15
Wisely, has very valuable information, and
1:19
also efforts being done to educate the public
1:23
about the CT and how we can do. In general,
1:28
CT technology or CT imaging is one of
1:32
the most commonly done imaging in the hospital these days.
1:37
In fact, on a consistent surveys,
1:40
the CT comes in the top 30 major
1:44
innovation in medical science over the last 50 years,
1:48
because the CT images provide such a dramatic
1:52
information quickly to allowing physician
1:56
to diagnose rapidly.
