Current modalities used for the detection and treatment of cancer suffer from the lack of specificity for tumor cells. Radiolabeled monoclonal antibodies have been, and continue to be, actively investigated for use in this regard. Various radionuclides, cell cultures, and radiolabeling processes have been examined, aimed at producing a product with sufficient immunoreactivity to enhance the use of these agents in various radioimmunodetection, radioimmunotherapy and radioimmunoguided surgery capacities. Antibody production, radiolabeling and radionuclide selection criteria, and quality assessment techniques for radiolabeled monoclonal antibodies are reviewed.

More and more high-spatial resolution satellite images are produced with the improvement of satellite technology. However, the quality of images is not always satisfactory for application. Due to the impact of complicated atmospheric conditions and complex radiation transmission process in imaging process the images often suffer deterioration. In order to assess the quality of remote sensing images over urban areas, we proposed a general purpose image quality assessment methods based on feature extraction and machine learning. We use two types of features in multi scales. One is from the shape of histogram the other is from the natural scene statistics based on Generalized Gaussian distribution (GGD). A 20-D feature vector for each scale is extracted and is assumed to capture the RS image quality degradation characteristics. We use SVM to learn to predict image quality scores from these features. In order to do the evaluation, we construct a median scale dataset for training and testing with subjects taking part in to give the human opinions of degraded images. We use ZY3 satellite images over Wuhan area (a city in China) to conduct experiments. Experimental results show the correlation of the predicted scores and the subjective perceptions.
