Autor: James J. Weinkam, Wilfred L. Rosenbaum, Theodor D. Sterling, Harold Perry, A. Glicksman, David A. Sterling

Publikováno v: Journal of clinical epidemiology. 49(7)

Insofar as industrial and other blue collar workers are more likely to bring home toxic materials on their person, and also are more likely to smoke than those in other occupations, members of a household are more likely to be subject to paraoccupati

A programmable calculator to acquire, verify and record radiation treatment parameters from a linear accelerator

Autor: Michael M. Lefkofsky, Joseph Mantel, Harold Perry

Publikováno v: International Journal of Radiation Oncology*Biology*Physics. 1:1023-1026

A system has been developed for the utilization of a Wang 600-14 programmable calculator to acquire, verify and record treatment parameters from a linear accelerator. The hardware and software components and operation of the system are briefly descri

Automation of Radiation Treatment Planning. V—Calculation and Visualisation of the Total Treatment Volume

Autor: Harold Perry, Theodor D. Sterling, James J. Weinkam

Publikováno v: The British Journal of Radiology. 38:906-913

The method for calculating per cent depth doses for all points in the major plane of a 60Co beam has been extended to all points in the treatment volume. An outline for rapid calculation of volumes of co- or multiplanar treatment plans is presented a

A Practical Procedure for Automating Radiation Treatment Planning

Autor: Harold Perry, Gustav K. Bahr, Theodor D. Sterling

Publikováno v: The British Journal of Radiology. 34:726-733

A simple method for the translation of isodose graphs into numerical grids is described and the use of these grids for automatic dose computation of multiple field treatments is demonstrated. Details of the preparations of grid values, I.B.M. cards,

Automation of radiation treatment planning. III. A simplified system of digitising isodoses and direct print-out of dose distribution

Autor: Theodor D. Sterling, Harold Perry, James J. Weinkam

Publikováno v: The British Journal of Radiology. 36:522-527

A system of automated treatment planning is described which enables the radiologist to obtain a direct print-out to scale of dose distribution. This system requires a new and simple method of digitising isodose curves which is also given.

Automation of Radiation Treatment Planning—IV. Derivation of a Mathematical Expression for the per cent Depth Dose Surface of Cobalt 60 Beams and Visualisation of Multiple Field Dose Distributions

Autor: Leo Katz, Harold Perry, Theodor D. Sterling

Publikováno v: The British Journal of Radiology. 37:544-550

A formula is presented for approximating the per cent depth distribution resulting from any portal size 60Co beam at 80 cm SSD. This equation may be used to obtain computer print-outs of combined multifield dose distributions as described previously
