Effect of Radiation Dosage on the Results in Carcinoma of the Cervix

Radiology, 1952
It is well recognized that gradual improvement over the years in the apparatus and technic of radiation therapy has resulted in more effective treatment of cancer. In the series of cases of carcinoma of the cervix here presented, a change in equipment provided a dividing line for a demonstration of the influence of the factor of radiation dosage.

Considerations of the Limits of Radiation Dosage from Thorotrast

The British Journal of Radiology, 1955
The use of a colloidal suspension of thorium dioxide as a radiological contrast medium dates from about 1928 (Bluhbaum, Frik and Kalkbrenner, 1928; Radt, 1930a, 1930b) and Thorotrast is the best known of such preparations. While excellent results are obtained in angiography, hepatography, arthrography, etc., and in the main no undesirable side ...

OPTIMIZING IMAGE QUALITY, RADIATION DOSAGE TO THE PATIENT AND TO THE DETECTOR IN PEDIATRIC CHEST RADIOGRAPHY: A PHANTOM STUDY OF A PORTABLE DIGITAL RADIOGRAPHY SYSTEM.

Radiation Protection Dosimetry, 2019
The present work aimed to optimize exposure settings in pediatric digital chest radiography (DR) with regard to image quality and radiation dosage. A pediatric phantom was imaged with a portable DR unit to examine different exposure settings (range: 75 ...

Stereolithographic modelling and radiation dosage

British Journal of Oral and Maxillofacial Surgery, 2003
Hughe’s paper1 highlights the use of stereolithographic models to facilitate custom-made titanium prosthesis for simple orbital floor reconstructions. In more complex orbital, defects mirror imaging the normal orbit can be helpful in determining the correct shape and volume of the damaged orbit.2 The benefits of these techniques must be weighed against

Monitoring Ultraviolet Radiation Dosage Based on a Luminescent Lanthanide Metal-Organic Framework.

Inorganic Chemistry, 2018
A luminescent lanthanide metal-organic framework [Tb7(OH)8(H2O)6(IDA)3(COO)3]·4Cl·2H2O (Tb-IDA, IDA = iminodiacetic acid) was hydrothermally synthesized and structurally characterized.

Dosage in Radiation Therapy [PDF]

The British Journal of Radiology, 1935
There are two distinct aspects from which the subject of dosage in radiation therapy can be regarded. The first is the physical aspect concerned with the accurate measurement of and statement of dosage. The second is the purely clinical aspect concerned with the determination of the appropriate doses required in actual clinical practice.

Reducing the radiation dosage in patients with a scoliosis

International Orthopaedics, 1989
A significant number of girls develop an adolescent idiopathic scoliosis and require repeated full-length radiographs of the spine. Since Nash's publication in 1979 [16], there has been considerable concern expressed about protecting them from excessive radiation, and particularly from the development of radiation-induced breast tumours.

Radiation Dosage Estimation and Health Risk

JAMA: The Journal of the American Medical Association, 1992
To the Editor. —Erroneous conclusions will be drawn from the article of Wing et al, 1 which described evidence of radiation effects in Oak Ridge (Tenn) National Laboratory workers, if the very large biases and uncertainties in relating effects to radiation doses are not recognized.

Radiation Dosage Planning and Dosage Calculation

Radiology, 1952
In radiation therapy it is generally appreciated that tumor effect is dependent on tumor dose, and on the total time during which this dose is administered. For a particular patient and series of treatments, determination of tumor dose requires the following procedures: 1.

Radiation Dosage to Medical Personnel

American Industrial Hygiene Association Journal, 1960
A survey was made to evaluate exposure to those physicians and dentists employing radiation. Many medical personnel other than radiologists employ radiation such as the general practitioner, surgeon, urologist, and the dentist. It is emphasised that among the various specialty groups varied factors of kilovoltage, current filter, technique, etc., will ...
