Enhanced Distance Active Contour (EDAC) is introduced in order to solve the issue. In this paper, the efficiency of DAC and EDAC in segmenting characteristic details on breast phantom images is compared. In this study, the breast phantom is needed in order to test the applicability of EDAC, in the detection of the characteristic details hidden behind the phantom. The breast phantom refers to a test object used to simulate radiographic characteristics of compressed tissue. A phantom is designed to simulate x-ray attenuation of 4.2 cm compressed human breast which is composed of 50% adipose and 50% glandular tissue. Then, both methods are implemented on mammograms to segment microcalcifications [3]. Einally, the performance of both methods are measured and compared. This is to verify that the EDAC performs better than DAC.

A contusion is an injury to soft tissue in which the skin is not penetrated, but swelling of broken blood vessels causes a bmise. The bmise is caused by a blow of excessive force to muscle, tendon, or ligament tissue. A bmise, also known as a hematoma, is caused when blood coagulates around the injury causing swelling and discoloring skin. Most contusions are mild and respond well to rest, ice, compression, and elevation of the injured area. 

Microscopic examination of the heart revealed edematous separation of myofibrils that had resulted in compression thinning and fragmentation of myofibres. Myofibre outlines were less distinct, and there was loss of acidophilic staining. Mitotic figures were rare, indicating that growth of the cardiac tissue was suppressed. The incidence of cardiac lesions is given (Table VI). 

Compressed gases, therefore, present a unique hazard from their potential physical and chemical dangers. Unless cylinders are secured they may topple over, cause injury to operators, become damaged themselves and cause contents to leak. If the regulator shears off, the cylinder may rocket like a projectile or torpedo dangerously around the workplace. Other physical hazards stem from the high pressure of a cylinder s contents, e.g. accidental application of a compressed gas/air hose or jet onto an open cut or wound, whereby the gas can enter the tissue or bloodstream, is particularly dangerous. 

Figure 7.7. A finite element model of a bone specimen in compression. This model was created by converting the voxels from a microcomputed tomography scan into individual bone elements. Loads can then be applied to the model to understand the stresses that are created in the bone tissue.

The authors have now reviewed in detail four cases of unexpected death following the use of neck holds in PCP-intoxicated individuals. In all of the cases, multiple carotid compression holds had been attempted, according to the history. Skin abrasions, hemorrhage into the soft tissues of the neck, and fractures of the hyoid bone and thyroid cartilage provide structural evidence of the application of substantial force to the neck. On autopsy, there has been no evidence of lethal injuries to the bronchial tree, bra in, or heart.

Muscle spasm. The pain induced by muscle spasm results partially from the direct effect of tissue distortion on mechanical nociceptors. Muscle spasm also causes tissue ischemia. The increased muscle tension compresses blood vessels and decreases blood flow. Furthermore, the increased rate of metabolism associated with the spasm exacerbates the ischemia. As discussed earlier, ischemia leads to stimulation of polymodal nociceptors.
