Objective:
To establish a complete technical solution for the radiation biological dose estimation, to enable prediction of individuals' response to radiotherapy (RT), and to control treatment dose for reduced irradiation injury and promote repair; and to evaluate the risk of radiation-induced late effects for patients undergoing external photon beam RT and provide the reliable dose-response relationships.
Methods:
Select 49 tumor patients using 60Co and linear accelerator for radiation therapy; initial radiation dose was 250 cGy. Chromosome aberration and blood count were analyzed before radiation therapy and 2 hours after the first day of RT.
Results:
Two hours after the first day of RT, peripheral blood cell count of lymphocytes of patients with cancer was significantly decreased (P < .01). The frequency of chromosome aberration was higher (P < .01).
Conclusion:
High-dose radiation of the radiation therapy makes significant injuries to peripheral blood lymphocytes.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
