Accurate knowledge of gantry angle is essential in megavoltage cone beam imaging (MVCBI) with an electronic portal imager. We present a method for determining the gantry angle by detecting multileaf collimator (MLC) leaf positions in projection image

Irradiation of the arterial wall with beta particles has been shown to be effective in inhibiting neointimal hyperplasia following percutaneous transluminal coronary angioplasty (PTCA). In this study, we describe the use of 188W/188Re generators to o

Recent preclinical and clinical studies indicate that irradiation using ionizing radiation in the dose range of 15 to 30 Gy may reduce the occurrence of restenosis in patients who have undergone an angioplasty. Several delivery systems of intravascul
