__Digital Picture Generation and Multi-Frame Sine Wave Image Creation__

**iLAB OVERVIEW**

**Introduction**

Today, most medical imaging modalities generate digital images, which easily can be manipulated by computers. The digital medical image is structural and functional information of human body in digital form. This laboratory activity focuses on digital picture element, known as *pixel *, generation. The digital image consists of pixels. Also, this laboratory creates an image of sine wave with different spatial frequency and phase.

Generally, the pixel is expressed in the two-dimensional arrays *p (m, n) *notation, where m is the row number and n is the column number of that particular pixel. The number of pixels in a digital medical image is its spatial resolution, which relates to the image quality.

**Objective**

- The objective of this exercise is to generate a two-dimensional square or rectangular shape as a basic digital image with varying intensity.
- The objective of the second part is to create an image of a sine wave having a spatial frequency with different phases.

**Materials**

- MATLAB software
- Image Processing Tool

**INSTRUCTIONS**

**Part A: Generate a two-dimensional square and rectangular shape digital image.**

**Problem**

The digital image should be 20 x 20 pixels in size and a complete white object against a black background.

Follow the instructions as shown below:

- Start MATLAB software.
- Click File, and then New, and then Blank m-file.
- Write a simple program according to the above problem and save as xxx.m file in a directory.
- Go to Command Window. At the matlab prompt, type only xxx (your file name without .m) and press ENTER.
- Check your result.
- Open the xxx.m file and change the program as required. Now save the modified file.
- Go to command window again. At the matlab prompt, type the file name xxx again, and press ENTER.
- See the result and verify with your expected digital image. Capture the screenshot of the square image.
- Now change the dimension of the above square image and also change the location of the image with different intensities. Note, intensity 0 means black and intensity 1 means white. You can select any values between 0 and 1 for gray level pixel creation. Capture the screenshots of those modified square and rectangular images.

**Part A**

**Introduction**

Attenuation occurs when X-ray photons are removed from their beams when they go through an object, which is called attenuating medium. The attenuation of the photons depends on the material properties of the attenuating medium and its thickness. This lab will show how attenuation of X-ray photons is related to the thickness of the attenuating medium. Here, the stream of water represents a beam of X-ray photons, and the thickness of paper towels represents the attenuating medium.

**Preliminary Ideas**

- What effects do you think a thicker medium will have on attenuation?
- How will this affect the image?

**Table 1: **Record the amount of water that went through the paper towel here. Average the two values for each thickness and record that, too.

**iLAB OVERVIEW**

**Introduction**

Today, most medical imaging modalities generate digital images, which can be easily manipulated by computers. The digital medical image is structural and functional information of human body in digital form. This laboratory activity focuses on digital picture element, known as *pixel *, generation. The digital image consists of pixels. Also, this laboratory creates an image of sine wave with different spatial frequency and phase.

Generally, the pixel is expressed in the two-dimensional arrays *p (m, n) *notation, where m is the row number and n is the column number of that particular pixel. The number of pixels in a digital medical image is its spatial resolution, which relates to the image quality.

By this point, you have studied X-ray radiography, and you probably see the limitations it has. To overcome some (but not all) of these limitations, computed tomography (CT) is used. In this lab, you will see how computed tomography works by using a method called*back projection *. You will determine one-dimensional cross-sections of a slice of the object being imaged at different levels by combining multiple back projections of the same slice.

From these one-dimensional cross-sections, a two-dimensional slice can be made. Then, several two-dimensional slices will be combined to make a three-dimensional reconstruction. It is important to note, however, that usually doctors just look at the two-dimensional cross-sections to gather the information they need.

Although three-dimensional reconstruction makes it easier to see the structure, it provides only minimal new information at the cost of computer time and memory.

**Objective**

The objective of this laboratory exercise is to generate a two-dimensional square or rectangular shape as a basic digital image with varying intensity. Using radon transform to create projection of the digital image and from projection data, create a CT image by back projection method.

**Materials**

- MATLAB software
- Image Processing Toolbox

**INSTRUCTIONS**

**Procedure**

1. Set up the MATLAB and create a white square object with black background.

Image dimension: 256 x 256 pixels
