Fig. 2From: Correlation between patients’ anatomical characteristics and interfractional internal prostate motion during intensity modulated radiation therapy for prostate cancerThree dimensional shifts of the prostate in individual patients. Lines indicate the range of prostate shift during 35–37 fractions for each patient. Dots show the mean of prostate shift from the original location determined by CT simulation. Columns represent the mean ± 1.96 SD, which indicate the range where the prostate is located with a probability of 95 % with an assumption of a normal distribution. a–c Lateral, craniocaudal and anteroposterior shift of prostate, respectivelyBack to article page
