Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Downsampling

Downsampling

When considering a sampled sequence with zero values between sampling instants, one can replace it by taking every N-th value of the sequence. At these integer multiples of N, the original and sampled sequences coincide. This process, known as decimation, involves extracting every N-th sample from a sequence, thereby creating a more efficient sequence.
The Fourier transform of the decimated sequence reveals a combination of scaled and shifted versions of the original spectrum. This...

Difference from Background: Limit of Detection

Difference from Background: Limit of Detection

The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Area of Science:

Medical Imaging
Digital Image Processing
Data Compression

Background:

Medical imaging generates large datasets, requiring efficient storage and transmission.
Existing compression methods may not optimally preserve diagnostic information or achieve maximum file size reduction.

Purpose of the Study:

To introduce and evaluate a novel image compression method using the Difference Transform for medical imaging.
To assess the effectiveness of the Difference Transform in improving image data decorrelation and encoding efficiency.

Main Methods:

The study applies the Difference Transform algorithm to medical image data.
The algorithm's decorrelation process is utilized to enhance the subsequent encoding stage.
Compression performance is benchmarked against standard medical image formats (TIFF, PNG) and other transforms (Cosine, Wavelet).

Main Results:

The Difference Transform method successfully decorrelates image data, leading to improved encoding.
The proposed compression technique achieves smaller file sizes compared to original images.
The method demonstrates competitive, and in many cases superior, compression performance relative to TIFF and PNG standards.

Conclusions:

The Difference Transform presents a viable and effective alternative for medical image compression.
This method offers significant file size reduction while maintaining image data integrity.
The Difference Transform can potentially replace conventional transforms like Cosine and Wavelet in medical imaging applications.
