Arterial stiffness (AS) refers to the loss of arterial compliance and alterations in vessel wall properties. The study of local carotid stiffness (CS) is particularly important since carotid artery stiffening raises the risk of stroke, cognitive impairment, and dementia. So, stiffness measurement as a screening tool approach is crucial because it c...
In this paper we proposed an algorithm for image de-nosing based on; the two level discrete wavelet transform (DWT), and Wiener filter, also this paper describe estimate noise power. At first The DWT transform noisy image into sub-bands, consist of lowfrequencyand high-frequencies, and then estimate noise power for each sub-band. The noise power is...
This study was undertaken to investigate the influence of static magnetic field (SMF) on bone marrow cellular density (BMCD) variation proportionally to bone trabeculae. Female albino Wistar rats exposed with 2.4 ± 0.2 millitesla for 1–4 weeks duration continuously versus 1 h, 2 h, 6 h, and 8 h/day. Trephine biopsy of femurs bone was examined under...
In this study, the influence of the static magnetic field (SMF) on blood platelets (PLTs) has investigated in-vivo experiments. Female albino rats exposed to the magnetic field for 1hr, 2hrs, 4hrs, 6hrs and 8hrs per day during 1-4 weeks. Platelet counts did not vary significantly for 1hr of exposure. The 2hrs/day exposure for 1 week and 6hrs/day ex...
This study aimed to investigate the in-vivo effect of a static magnetic field (SMF) on blood falling time and velocity in a capillary tube. We generated a magnetic field using Helmholtz coils. We exposed rats with 2.4±0.2mT for a duration of one-four weeks and 1-8hrs/day. Blood samples were withdrawn and passed through a capillary viscometer under...
In this study, we investigated the effect of the static magnetic field (SMF) on white blood cells (WBCs) for female albino rats using a fabricated exposure system of SMFs. Five main groups of animals exposed to 2.4±0.2 milli-Tesla (mT) for four weeks continuously. Five main groups (each group = 4 subgroups) have exposed to a different time of expos...
This study was undertaken to investigate the influence of a homogenous and uniform static magnetic field (SMF) on the main blood cell counts in vitro experiment. Fresh blood samples were collected from albino rats and exposed to SMF (2.4, 6, 25, 50, 75, and 100 mT) versus 15–60 min. Results showed a significant change of blood counts under the low...
The present study was undertaken to investigate the influence of the static magnetic field (SMF) on the platelets and red blood cells counts (RBCs), haemoglobin (HGB), haematocrit (HCT), mean cell volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) in female rats (in-vitro). The results were analys...
Pelviureteric junction (PUJ) obstruction is a condition frequently encountered in both adult and pediatric patients. Congenital abnormalities and crossing lower-pole renal vessels are the most common underlying pathologies in both men and women. There are different methods for detecting it the most usual, safe, and easy one is by ultrasound scannin...
Rate of radiation leakage from the CT-Scan rooms has measured for 10 public Hospitals in Iraqi Kurdistan, using radiation survey dosimeter. Annual exposure dose considered as a main factor to asses risks of that leakage on the health of operators and auditors. Average leakage dose measured at the control room, table of operators, the main doors, an...
