Here, we treat ICH diagnosis as an MIL problem, where a full scan is defined as a “bag” and each slice in the scan is defined as an “instance”. A scan is classified as ICH if at least one slice in this scan has ICH and is normal if all slices are normal. Few studies use MIL method in ICH detection [15, 16]. However, since in all new applications (e.g. MPR, CT angiography and CT endoscopy) the anatomic area of interest had to be covered with a single scan, it is evident that compromises were necessary (e.g. reduced mAs and scanning length, increase of pitch and slice thickness) in order to overcome the thermal capacity constraints of the X-ray tubes. We offer low-dose 64- and 128-Slice CT scans for specified imaging studies. We establish our scanning protocols based on age, weight, body type and area of interest to reduce radiation dose as low as possible. This approach applies to everyone including both children and adults. In this case, the agreement is always below 3% for abdomen scans and 1.0% for head examinations. This result implies that the radiation dose supplied by the 16-slice computed tomography (CT) system was in good agreement with the international dose reference level and we observed something different. Keywords: radiation dose, computed tomography By Perrine Juillion / November 21, 2019. Our study showed that CT images with slice thickness of <4 mm would be optimum for small targets (<20 cm 3) in IMRT of thoracic cancer patients. However, some studies revealed a noise-limited minimum thickness, such as the slice thickness of 1.2 mm superior to 0.6 mm because of increasing dimpling artifacts. 1DJv.
