Plán cvičení (Timetable and topics)

Labs take place on Wednesdays at 9:15-10:45 or 11:00-12:30, in room KN:E-230 (Karlovo nám.).

The title in italics means there is no session in the computer lab - it is either elsewhere or canceled.

The materials (or their final version) will be provided before each lab session.

Practical ultrasound experiments

We plan for you to perform some practical experiments with ultrasound. You will work in small groups. To accommodate all of you, some of the labs will be done outside the standard hours. Please make groups of 2-3 people, see the planning page and mark a slot by either adding a comment there or sending me an email.

Visit to Motol hospital

The following activity is not obligatory but highly recommended. If you want to participate, mark it in the table linked below (will appear in due course).

On Wednesdays 5.3. and 12.3., we will visit the Motol hospital. You will be shown some imaging devices (CT,MRI, nuclear imaging) and you are encouraged to participate in a functional MRI brain acquisition. This acquisition will be part of a research study and you will also be given your data to process them in the following computer exercises. We will go by groups, about 1/2 each week. Please see the planning table. If you are unable or unwilling to go a certain week, please inform me immediately, either by email or by adding a comment to the table. Both the visit and the acquisition is voluntary but I think it is a very interesting and unique experience and I strongly recommend it. The visit is expected to last a couple of hours (e.g. until 2pm). You should be at 11:00 in the “aula ředitelství FNM a děkanátu 2. LF UK” in the hospital. From the Motol metro station, you go straight across a little “square” (with a pharmacy and a small shop). It is not recommended to enter the hospital by other entrances as many passages are currently closed. If you get lost, call dr. Šanda (702 024 204) or Jiří Anýž (732 728 834). There will not be enough time for everybody to go to the scanner. If you want to go into the scanner, let us know or mark it in the table.

Visit to the Center of Advanced Preclinical Imaging

At the end of the semester, we will visit the Center for advanced preclinical imaging (CAPI). They have a number of medical imaging devices, including some exotic ones like magnetic particle imaging or photoacoustic imaging, mainly for imaging small animals. The visit is not compulsory but is strongly recommended.

The visit will take place from 9:00 till 11:00 on Wednesdays May 7 and May 21. We will meet in front of the building at Salmovská 3. Please come at least 5 minutes in advance - if you come late, you might not be able to enter. The detailed instructions are in the following documents ( CZ, EN).

As in the case of the previous visit, we will go in two groups. There is a planning table, where we divided you to the two dates in advance. If the assigned date doesn't suit you and you would like to go the the CAPI on the other date, please add a comment to your name in the table with the requested change. If you for any reason can't or don't want to go to the CAPI visit, please let us know by sending an email to anyzjiri@fel.cvut.cz or by adding a comment to your name in the table. If you do not come without letting us know in advance, we will consider this an anauthorized absence..

Lab equipment

MATLAB

Na cvičeních budete používat systém Matlab, který sdružuje prostředky pro výpočty, vizualizaci, ladění a programování numerických úloh. Jedná se o široce rozšířeným systémem pro vědecko-technicé výpočty. Je používán na více než 3500 universitách a ve stovkách velkých firem, podívejte se např. sem.

Jak ho získat

Matlab není zadarmo. Nicméně studující si mohou doma pro účely studia nainstalovat multilicenci ČVUT Matlabu s pomocí hlavního přístupového hesla.

Jak začít

Předpokládáme základní znalost prostředí Matlab, pokud si znalosti chcete osvojit, doplnit či připomenout, doporučujeme následující tutoriál (cz) a další materiály z webu.

We will use Matlab for computation, visualization and other numerical calculations. Matlab is commonly used tool in research and development from academia to private companies.

How to get it

For study purposes, students are allowed to use the CTU multi-licence of Matlab on their own computers. The main CTU password is required for downloading.

How to start

Please use one of the web tutorials to freshen or improve your MATLAB experience.
