Real-time monitoring and verification of in vivo high dose rate brachytherapy using a pinhole camera
Duan J, Macey D, Pareek P, Brezovich I
Med Phys
. 2001 Mar;
28(2):167-73.
PMID: 11243339
We investigated a pinhole imaging system for independent in vivo monitoring and verification of high dose rate (HDR) brachytherapy treatment. The system consists of a high-resolution pinhole collimator, an x-ray...

Brezovich I, Duan J, Pareek P, Fiveash J, Ezekiel M
Med Phys
. 2000 Dec;
27(10):2297-301.
PMID: 11099197
Radiation doses delivered in high dose rate (HDR) brachytherapy are susceptible to many inaccuracies and errors, including imaging, planning and delivery. Consequently, the dose delivered to the patient may deviate...

Brezovich I, Pareek P, Plott W, Jennelle R
Int J Radiat Oncol Biol Phys
. 1997 Jul;
38(4):883-90.
PMID: 9240658
Purpose: The purpose of this project was the development of a quality assurance (QA) system that would provide geographically accurate targeting for linac-based stereotactic radiosurgery (LBSR). Methods And Materials: The...

Kim R, Caranto J, Pareek P, Virostek L
Int J Radiat Oncol Biol Phys
. 1997 Mar;
37(5):1193-9.
PMID: 9169831
Purpose: To evaluate the dynamics of pear-shaped dimensions and volume of the intracavitary brachytherapy, and to define a desirable pear-shape in the era of three-dimensional (3D) treatment planning. Methods And...

Brezovich I, Pareek P, Spencer S, Salter M, Kim R
Int J Radiat Oncol Biol Phys
. 1994 Mar;
28(4):1025-8.
PMID: 8138428
Purpose: The purpose of the work was to develop a practical electron cone and to compare its dosimetry with that of the conventional applicator collimation system. Methods And Materials: The...

Brezovich I, Meredith R, Weppelmann B, Pareek P, Salter M
Int J Radiat Oncol Biol Phys
. 1991 Sep;
21(4):1073-83.
PMID: 1917605
A novel technique for setting up tangential fields is described. The technique uses a simple device (Breast Aligner) which attaches to the collimator of the treatment unit. The function of...
