Accelerated Partial Breast Irradiation (APBI) is a common treatment of breast cancer with many modalities including 3D Conformal Radiation Therapy (3D-CRT), Intensity Modulated Radiation Therapy (IMRT), and High Dose Rate Brachytherapy (HDR). In this research, a retrospective analysis of patient’s data was performed to analyze the NTCP/TCP (Normal Tissue Complication Probability/Tumor Control Probability) and Dose Volume Histogram (DVH) parameters for HDR with SAVI, 3D, and IMRT and compare them focusing on critical organs such as the heart, ipsilateral lung, chest wall, ribs, and skin. TCP was 90.275%, 55.948%, and 53.369% for HDR, 3D, and IMRT respectively. The ribs were the most sensitive critical organ for all 3 modalities with a mean NTCP of 8%, 15%, and 8% for HDR, 3D, and IMRT respectively. DVH analysis showed HDR spares critical organs more than EBRT except for 2 patients receiving high doses to the ribs and chest wall.

This study examines the development of German pipe organ culture and French classical pipe organ culture from a single common origin in the Duchy of Brabant, during 1450-1850, with respect to select major attributes of organ construction, organ music and organ technique. The respective music of Dieterich Buxtehude (1637-1707), Praeludium in G Minor, BuxWV 149, for the North German contrapuntalists, and of Câesar Franck (1822- 1890), Choral No. 3 in A Minor, for the classical French symphonic tradition, is highlighted and appended with suggested technique for each work.
