dc.description.abstract | 臨床超音波診斷儀的開發,是否能受到廣
大的使用者歡迎,決定於兩類主要的因素:
亦即客觀及主觀的因素。所謂客觀的因素指
的是系統本身的規格與品質是否能與同級產
品相競爭。而主觀的因素則是系統所提供的
功能是否合乎一般醫師之需求。本子計劃的
主要目標即是要發展一套臨床應用軟體不僅
能符合臨床之真正需求,更提供俱智慧且有
善的操作功能以節省醫師的操作時間。
為了要使醫師能以最少的步驟達成其所需
的軟體功能,半自動或全自動的影像處理技
術是此應用軟體成功與否的關鍵所在。是
以,於此計畫中,除了撰寫應用軟體及其中
必要的人性化人機介面之外,重點將在於研
發適用於超音波影像的影像處理演算法。由
於超音波的影像品質比其他的醫學影像的品
質差了許多,傳統的影像處理方法並不完全
適用。是以在此計畫中,我們將發展新的影
像處理技術,希望能讓使用者輕鬆的完成所
需的分析工作。於第三年的計畫中,我們提
出一個新的形變模型,稱為離散型梯度流形
變模型。此模型以對比梯度與叢聚元件強化
微弱邊緣。且以離散型梯度流導引遠處的初
始輪廓至目標物的邊緣。此模型已成功的應
用於超音波胎兒影像的分割。 | zh_TW |
dc.description.abstract | In the development of an ultrasound imaging
system, whether it will become a popular
system strongly depends on two factors,
namely, objective and subjective factors.
While the objective factor means whether the
specification and the quality can be compete
with other products of the same class, the
subjective factor means whether the operation
functions match most doctors' needs. The
goal of this component project is to develop an
application software with operation functions
not only matching clinical needs but also being
intelligent and user-friendly to minimize a
doctor's operation time.
In order to allow a doctor to complete an
operation function with the minimal effort,
semi-automatic and automatic image
processing algorithms would be the key
technology. Therefore, in this project, in
addition to write the application software and
its user-friendly man-machine interface, the
emphasis would be on developing the image
processing algorithms suitable for ultrasound
images. Since the quality of an ultrasound
image is much worse than that of other types of
medical images, the conventional image
processing techniques may not be very
effective for an ultrasound image. Hencs, in
this project, we have put a great effort on
developing new image processing algorithms to
deal with images for different applications,
hoping that the user can easily complete their
desired operation functions. In the third-year
project, we have proposed a new deformable
model, called Discrete Gradient Flow
Deformable Model. The salient features of
this model are to enhance the weak edges by
using the contrast gradient and the connected
components and guide the distant initial
contour with the new image force, i.e., the
Discrete Gradient Flow. This model has been
verified by using a set of ultrasound fetus
images. | en |
