[The multi-resolution image registration algorithm for digital subtraction angiography].
The proposed registration algorithm based on wavelet transform is a multi-resolution block matching one, which exploits the hierarchical self-similarity of Digital Subtraction Angiography images. This method befittingly trades off between the estimation precision and computational complexity, because the registration precision is from coarse to fine, which reduces the searching complexity of motion vector. ⋯ The proposed method takes full advantage of the precise location both temporally and frequently which characterizes the wavelet transform. Both the matching speed and consistency are boosted without the loss of matching performance.

[Development and application of ultrasound technology for hyperthermia].
It has been a long time since ultrasound hyperthermia began to be used in the clinical management of cancers and benign diseases. Numerous biological and clinical investigations have demonstrated that: hyperthermia in the range of 41-45 degrees C can significantly enhance clinical response to radiation therapy and chemotherapy, and high-temperature hyperthermia (greater than 65 degrees C) alone is now being used as an alternative to conventional invasive surgery for selective tissue destruction, causing tumor coagulation and necrosis. ⋯ China is advanced in the clinical applications of HIFU. This article gives an introduction of the development and applications of ultrasound hyperthermia technology, and also provides a general review of a selection of ultrasound hyperthermia systems both in clinical use and under development.
