1. The dose comformity and normal tissue isodose characteristics were compared by four stereotactic techniques of radiotherapy for two tumor target shapes.

2. A median dose of 20 Gy isodose line was administered in a single fraction.

3. The reference dose curve was the isodose curve of 90 % .

4. Search and plot isodose curve is a one of foundation study in radiation dosimetry.

5. Objective To measure and evaluate the distribution feature of radiation dose at the conventional puncture plane in invasive diagnosis and treatment area, and depict the corresponding isodose curve.

6. In this pa-per, we introduce a new method for search and plot isodose curve by scan row and column one by one.

7. Results The planning target volume was enclosed by 95% isodose line while the dose to the organ at risk were kept below TD5/5 significantly.

8. Objective To investigate correlative question about the same A point but different isodose curve in therapy of cervical carcinoma.

8. try its best to gather and create good sentences.

9. The technologies are emphasized, including image collection, preprocessing, edge detection and selection, calculating the dose of the point and drawing the isodose .

10. In the oblique incidence, the movement of 80% and 50% isodose lines in horizontal direction should be noted, otherwise the dose of some tumor will be very low.

11. Biological effective dose (BED) was calculated by LQ model. The difference between the BED curve drawn in the central layer and the physical isodose curve was studied.

12. A median dose of 20 Gy prescribed to the 80% isodose line was administered in a single fraction.
