Ultrasound

this theory, violent collapses of cavitation bubbles produced by power ultrasound can generate very high localized pressure in a very short time. Such collapse generates high degrees of super cooling and favors instantaneous ice nucleation. According to this theory, nucleation is expected to occur immediately after the collapse of cavitation bubbles. Molecular segregation is another theory proposed to explain the power ultrasound induced nucleation in the crystallization process of different…

between 50-60 years old. The use of ultrasound is then used to get a closer look so the doctor will be able to better diagnose if the mass is IDC with metastases…

Discussion Elastography is a non-invasive imaging modality that detects tumors based on their stiffness (elasticity) compared to normal tissue. Generally breast cancer tissue is harder than normal breast tissue. With elastography the elastic properties of breast tissue can be imaged in real time by means of color-coded superimposition on the B mode image and then used for differentiating between benign and malignant breast lesions (8). Elastography is a supplementary method for conventional US…

about is for astronauts in space. With longer human stays in space and prospects of long term space travel, some thought it would be a great idea to have medical imaging for the space travelers. Ultrasound was chosen because it encompasses a broad base of pathologies. In 2001, NASA integrated an ultrasound into the Health Research Facility on the International Space Station with the hopes of providing astronauts with diagnostic imaging. Most sonographers go through intensive training to become…

mediastinal masses (Fig 25) found in the anterior and middle compartments.These spaces are accessible by ultrasound, a fact that allows to study these mediastinal masses and assess vessel infiltration or cystic nature of these lesions (Mathis et al.,2010). The evaluation of mediastinal lymph nodes have better results with ultrasound than with conventional radiology . The overall sensitivity of ultrasound for the study of mediastinal lymph nodes is 62% ( Vollmer and Gayete 2010).…

programs and higher degree of health awareness there is relative decreased incidence of breast cancer mortality.(2) The main modalities which are used in breast imaging are mammography which is the reference technique, sono-mammography and MRI. B- mode ultrasound is considered as the complementary examination for the investigation of breast…

distended fallopian tube with distal occlusion, and occurs in the setting of previous pelvic inflammatory disease. The appearance on grayscale ultrasound is of a tubular and elongated cystic mass with incomplete septations or indentations along its walls (“waist sign” or “cogwheel”)[18]. In order to fully appreciate the tubular structure of the cyst, the ultrasound probe may be turned by a 90° angle, and a seemingly simple cyst will appear to be tubular (Figure. 25). In the chronic stage, small…

the pregnant woman comes to her first examination, the midwife must measure her blood pressure, height, weight and weight gain during pregnancy. The two most commonly used pregnancy detection diagnostic techniques are a transvaginal ultrasound and the abdominal ultrasound. Health care in pregnancy includes educating pregnant woman about her physical activity, eating habits, body care, clothing and footwear and sexual intercourse during…

return if the root cause of the effusion has not been addressed. Obtaining a chest x-ray is one of the first diagnostics one can order, followed by computed tomography and ultrasound of the chest to discover pleural effusions (Saguil, Wyrick, & Hallgren, 2014). Because pneumonia can cause these presenting…

which are just different variations of 3D reconstruction . 3D reconstruction is most commonly used by the medical field to examine the interior of the human body through a variety of different medical imaging technologies, such as MRIs, CT scans, ultrasounds, PET scans, and x-rays. In…
