Intranasal localization of radioactive I-131 was significant in patients receiving a dose of ≥150 mCi. Intranasal localization may partly explain toxicity to nasolacrimal duct and may be a risk factor for subsequent development of nasolacrimal duct obstructions.

An image compression system has been implemented using DSP 56000/96000 family of processors. Block processing is done on image data of 8x8 size to reduce I/O overheads. The coding scheme uses Discrete Cosine Transform (DCT) followed by a Llyod-Max quantizer. A multiprocessor system using these processors has also been designed for compression of 512x512 images in real time.
