And furthermore we developed the integrated HIFU system with 256-element HIFU transducers. And we made preliminary and important progresses in the research of HIFU bioeffect, lesion estimation, techniques of monitoring and imaging and characterizing of structure of HIFU transducer;(4)The real-time method of voice source regeneration based on compensative regulation of physiological parameters was investigated in the field of medical rehabilitation. We addressed the physiology and biophysics of vocalization, modeled voice source regeneration based on compensative regulation mechanism, and put forward an integrated evaluation about the speech rehabilitation and the regenerated voice source; Sixty-one archived journal papers were published, as well as ten in international journals, and eighteen publications were embodied by SCI.

MPR and VR were applied in the imaging post-processing. Results: All cases were divided into four groups according to the thoracic CT findings and pathologic results as follows:① spheral caseous pneumonia;② tuberculous granuloma;③ fibrous caseous nodule;④ Focal pulmonary consolidation with cavitation. The spheral lesion appeared inhomogeneous density (44/58). cavitation (14/58) or satellite foci (21/58). Contrast scanning was carried out in 31 cases, of which peripheral or ringshaped enhancement was seen in 15 cases, no enhancement in 9 cases and extensive enhancement was seen in 7 cases.

结果：依据影像学表现、随访结果和病灶的病理改变，将58例球形肺结核分为四种类型：①球形干酪肺炎11例，体积较大（最大直径3~5cm），边缘模糊或毛糙，可见晕征，无强化或环行强化；②结核性肉芽肿19例，软组织密度，形态规则或不规则，边缘清楚或光整，强化模式为均匀强化或厚壁强化；③纤维干酪结节14例，规则球形，边缘光滑锐利，内部密度不均匀，可见钙化，多无强化或薄壁环行强化；④结核空洞14例，干酪空洞或纤维空洞，内壁不光整，可见到引流支气管（2例）。

2The difference of conventional X-ray and CT:results showed that CT was better than X-ray in depicting the signs such as density,lobulation,spiculate protuberance,mediastinum lymphaden,X-ray was better than CT in contour and edge of solitary globular lesion of the lung.

X线、CT表现差异：肿块密度、分叶、棘状突起、纵隔淋巴结肿大的观察CT优于胸片，病灶形态、边缘的显示胸片较CT优越。

Results: The main manifestations of imaging in PCCCL appeared as peripheral nodules or masses (6/7) in the right lung. Tiny nodules with coarse spiculate margin, lack of pleural indentation and vacuole sign. When masses of turmor grew larger, smooth margins were found in them. spinous process and cavity were seldom seen. Central mass of left lung superior lobe (n=1), lesion was lobulated, and with smooth margin, which seem others central carcinoma of the lung.

结果：PCCCL影像学上主要表现为右肺周围性肿块或结节(6/7)，结节边缘可见毛刺征，无胸膜凹陷征、空泡征；肿块较大时，边缘光滑，无棘状突起、空洞等征象，1例左肺上叶中心性分叶状肿块，边缘光滑，酷似其它类型肺癌。

Results The main CT finds were as follow:①Bilaterial margins of the lesion were perpendicular to pleura with a straight cut edge presenting a square sign;②The density at the central area,some-times presenting a halo-like apperance;③Irre-gular or spiculate margins with illdefined outline could be seen;④There was extensive pleural thickening involving interlobar fissure as a response to inflamation;⑤There were small patches of slightly high density and intensified vascular markings surrounding the lesions;⑥After short-term anti-inflam-matory therrapy,most lesions were obviously reduced in size.
