I. Answer the question:

How is DSP used in computed tomography?

1. X- rays from only one direction are passed through a part of a human body.

2. Images formed by X- rays are stored in the computer.

3. Images formed by X- rays overlap each other giving a clear view of the patient's body.

4. Images formed by X- rays are converted into digital data and stored in the computer.

II. Decide which statement matches the text:

1. X-ray images show the clear distinction between the body of a living person and a dead one.

2. X-ray images always show the clear distinction even between very similar tissues.

3. DSP allows to calculate the digitized images of human body processed by a computer.

4. The two contributors of a computer tomography principle have never gained any recognition.

III. Decide which statement does not match the text:

1. X-ray imaging is very simple due to the fact that there are no overlapping structures within our body.

2. X-ray imaging does not show the details of the body's operation.

3. X-ray exposure is extremely dangerous for a human body.

4. It was quite easy for the major hospitals to gain access to computed tomography.

IV. Decide which definitions match the following terms:

1. tissues a) long parallel bones in the upper part of a body

2. ribs b) crossing each other, intersecting

3. DSP c) turning sensory signals into a digital form

4. overlapping d) soft structures of a body

V. Fill in the gaps with the words from the list below:

physiology, slices, computed, tomography, anatomy,

to calculate, overlapping

1. Digitized information is stored in the computer and then used ________________ the images of the living organism.

2. _______________________ allows better diagnosis and treatment.

3. X- ray imaging gives a full picture of human________________ , the structure, not of its ________________, the work of the body.

4. Computed tomography allows us to see the difference between _________________ organs and ________________of the body.

VI. Match the words in the right and left columns to make up a word expression from the text:

1. cause a) structures

2. overlapping b) fields

3. X- ray c) tomography

4. magnetic d) cancer

5. computed e) data

6. digital f) images

7. calculate g) exposure
