We aimed to study the effects of an anti-gravity treadmill (AlterG) training on balance and postural stability in children with cerebral palsy (CP). AlterG training was performed 3 days/week for 8 weeks, with up to 45 minutes of training per session. The subject was evaluated before and after the 8-week training. The effects of training on the balance and postural stability was evaluated based on...
In this paper, we used ICA based artificial neural network (ANN) and propose a robust technique for efficient 2D echocardiography image analyzing. This project can be divided in three parts. The first part is cardiac motion estimation from sequence of echocardiography. The second part is feature extraction from motion patterns using sources, these sources is derived from independent component analyzing...
The advantages of magnetic resonance imaging (MRI) over other diagnostic image modalities are its high spatial resolution and excellent discrimination of soft tissues. Many neurological conditions alter the shape, volume, and distribution of brain tissue; MRI is the preferred imaging modality for examining these conditions which requires segmentation into different intensity classes which are regarded...
In this paper, we propose an encryption scheme for the medical image encryption based on combination of scrambling and confusion. Chaotic cat map is used for the scrambling the addresses of the medical image pixels. In order to provide security for the scheme, a modified form of Simplified version of Advance Encryption Standard (S-AES) is introduced and applied. The modification is that we make use...
In this paper we used Independent Component Analysis (ICA) model of EEG signals for preprocessing and then Discrete Wavelet Transform (DWT) analysis for feature extraction from EEG signal which this features are useful in BCI application. Then we used Fuzzy C-means (FCM) algorithm for recognition of some diseases like epileptic seizure, Cerebral Palsy (CP), etc. This project can be divided in three...
Diagnostic techniques in cardiology require complex image analysis of single images and image sequences obtained by a variety of medical imaging modalities such as ECG gated MR, CT, and ultrasound. In particular, useful information about the cardiac function can be extracted from motion analysis of a beating heart. Accurate quantitative of heart motion and deformation are more important for evaluating...
With development of information and communication technology, data transmission becomes more critical day by day. Higher security for transmitting data is especially required. Therefore; we designed a new method to transmit data on the phone line where there is no speech signal on it. Statistic investigations in one communication center in Iran show that there is about 57% non-speech signal on the...
As we know different brain regions have specific functions. And also before performing any surgery on the brain, including surgery for the treatment of epilepsy, the surgeon seeks to understand the functions of the areas affected by the seizures or of the lesion. The attempt to specify in as much detail as possible the location of function in the human brain is called Brain mapping. In this paper...
