The detection of the pectoral muscle boundary in the medio-lateral oblique view of mammograms is essential to improving the computer-aided diagnosis of breast cancer. In this study, a shape-based detection method is proposed for accurately extracting the boundary of the pectoral muscle in mammograms. A shape-based enhancement mask is applied to the mammogram and the initial boundary is then def...

[Purpose] To evaluate differences in pectoral muscle tightness according to arm abduction angle and to determine the best arm abduction angle for stretching of pectoral muscle tightness in breast cancer patients. [Subjects and Methods] Horizontal abduction differences of shoulders were measured bilaterally by arm abduction to 45°, 90°, and 135° to determine the best arm abduction angle for meas...

Myopotential oversensing in implantable defibrillators causing inhibition of pacing and inappropriate therapies is well described. Current literature is dominated by reports of diaphragmatic muscle as the source of such far-field oversensing. Those reporting pectoral muscle sources were invariably due to unipolar sensing circuits, incorrect DF-1 connections or inappropriate programming. We repo...

Mammograms are used to screen for breast cancer and computerized analysis of these images can aid radiologists in detecting the disease. Any computerized method to analyze digitized mammograms must first partition the image into its visually and anatomically distinct regions. The pectoral muscle appears on mediolateral oblique views of mammograms and needs to be identified and segmented out bef...

Breast cancer is the most common form of cancer among women in many regions of India. One out of every 22 women is diagnosed with breast cancer. Mammography acts as an early detection tool for breast cancer and can detect tumors up to two years before it can be felt. Numerous studies have shown that the early detection saves lives and increases treatment options. Mammography is one of the X-ray...

The high molecular weight actin-binding protein filamin is located at the periphery of the Z disk in the fast adult chicken pectoral muscle (Gomer, R. H., and E. Lazarides, 1981, Cell, 23: 524-532). In contrast, we have found that in the slow anterior latissimus dorsi (ALD) muscle, filamin was additionally located throughout the l band as judged by immunofluorescence with affinity-purified anti...
