Computerized quantitation of regional myocardial perfusion in man
Autor: C. M. Kronenwetter, Josep G. Llaurado, R.C. Meade, J. D. Horgan, Virinderjit S. Bamrah, P. P. Ruetz
Publikováno v: International Journal of Bio-Medical Computing. 11:501-510
A computerized procedure has been developed for the generation, graphic presentation and quantitative evaluation of circumferential profiles of thallium-201 myocardial perfusion. The computer data are first filtered using a two-dimensional fast Fouri

Analog Computer Studies of Periodic Breathing
Autor: J. D. Horgan, D. L. Lange
Publikováno v: IRE Transactions on Bio-Medical Electronics. 9:221-228
A classical clinical experiment, in which periodic breathing is induced in a normal subject by hyperventilation, has been successfully simulated on the high speed analog computer. The model, together with its underlying theory, is presented. Its appl

Accurate determination of capacitance by conjoining analytical and analog techniques
Autor: J. A. Pesavento, J. D. Horgan
Publikováno v: Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics. 77:397-400
The principal objective of the work described in this paper is to develop a new method for accurately determining the capacitance associated with 2-dimensional composite regions. The term capacitance refers to the ordinary electric capacitance associ

Minicomputer enhancement of scintillation camera images using fast Fourier transform techniques
Autor: M J, Sebern, J D, Horgan, R C, Meade, C M, Kronenwetter, P P, Ruetz, E L, Yeh
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 17(7)
Minicomputer methods were developed to enhance lesions in scintillation camera images. This study was directed towards improving the diagnostic quality of liver images. A PDP-12 digital computer was interfaced to a Pho/Gamma HP III scintillation came

Quantitative analysis of liver scan data as an aid to diagnosis
Autor: E. D. Grassman, R. C. Meade, J. D. Horgan
Publikováno v: Radiology. 95(3)
Data for the digital-computer method are obtained from a scintillation camera and processed in a Linc-8 computer. Computer output consists of an oscilloscope display of the outlined liver and located defects plus print-out of the quantitative interpr
