Problems created in attenuation-corrected SPECT images by artifacts in attenuation maps: a simulation study
Autor: Anna, Celler, Katherine L, Dixon, Zheng, Chang, Stephan, Blinder, John, Powe, Ronald, Harrop
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 46(2)
The importance of accurate attenuation correction, especially for imaging of the thorax region, is widely acknowledged. Appropriate compensation methods have been developed and introduced into clinical practice. Most of these methods use attenuation

Publikováno v: International Journal of Radiation Oncology*Biology*Physics. 7:267-275
Consideration of radiation dose rate effects emphasizes advantages of the template method for lateral distribution of multiple sources in treatment of laterally infiltrating gynecologic cancer, when compared to a conventional technique with colpostat

Some structure results for propositional calculi
Autor: Ronald Harrop
Publikováno v: Journal of Symbolic Logic. 30:271-292
1. Introduction. Since this paper is a written version of one presented as a survey lecture at a meeting of the Association for Symbolic Logic, its form and content have been essentially determined by the form and content of that lecture, and these l

Uniformization of linear arrays
Autor: Ronald Harrop, N. J. Fine
Publikováno v: Journal of Symbolic Logic. 22:130-140
In Chapter X of his book on The structure of appearance, Goodman [1] studies the concept of linear order in finite linear arrays in terms of a two-place symmetrical predicate M, M(x, y) being read as x matches y. Although arising in the development o

Concerning formulas of the types A→B ν C,A →(Ex)B(x) in intuitionistic formal systems
Autor: Ronald Harrop
Publikováno v: Journal of Symbolic Logic. 25:27-32
In a previous paper [1] it was proved, among other results, that a closed disjunction of intuitionistic elementary number theory N can be proved if and only if at least one of its disjunctands is provable and that a closed formula of the type (Ex)B(x
