1.
Miller T, Jost R, Sampathkumaran K, Blaine G
Semin Nucl Med
. 1990 Jul;
20(3):270-5.
PMID: 2367872
Nuclear medicine provides a good environment for the evaluation of picture archiving and communication systems (PACS) because of the relatively small quantity of digital data that are generated, leading to...
2.
Miller T, Wallis J, Sampathkumaran K
J Nucl Med
. 1989 Dec;
30(12):2036-41.
PMID: 2585107
There has been little interest in use of single photon tomography in gated cardiac blood-pool imaging. This fact arises most likely from two principal causes: the difficulty associated with interpretation...

Miller T, Hagge R, Wallis J, Sampathkumaran K
IEEE Trans Med Imaging
. 1988 Jan;
7(3):188-92.
PMID: 18230467
The use of a novel class of image processing hardware, the image computer, is illustrated by application to gated cardiac studies. Digital filtering of a nine-view study consisting of 144...

Sampathkumaran K, Miller T
Eur J Nucl Med
. 1987 Jan;
13(4):161-6.
PMID: 3622561
An image network that is in use in a large nuclear medicine department is described. This network was designed to efficiently handle a large volume of clinical data at reasonable...

Miller T, Goldman K, Epstein D, Biello D, Sampathkumaran K, Kumar B, et al.
Radiology
. 1984 Sep;
152(3):795-800.
PMID: 6611565
The authors describe a digital filter that greatly enhances the quality of gated cardiac blood-pool images. Spatial filtering is accomplished with a minimum-mean-square-error (Wiener) filter incorporating measured camera blur and...

Miller T, Sampathkumaran K, King M
J Nucl Med
. 1983 Jul;
24(7):625-8.
PMID: 6864316
Image filtering with the larger, and potentially most valuable, digital filters is very time-consuming, thus precluding use of these filters in routine clinical applications. A recently developed algorithm for spatial-domain...

Miller T, Goldman K, Sampathkumaran K, Biello D, Ludbrook P, Sobel B
J Nucl Med
. 1983 Jan;
24(1):2-7.
PMID: 6848698
Separation of systolic and diastolic parameters in gated cardiac blood-pool imaging (RVG) was achieved with the retention of two harmonics in the Fourier-series representation of the time-activity curve. Regional and...

Miller T, Sampathkumaran K
Eur J Nucl Med
. 1982 Jan;
7(1):22-7.
PMID: 7060600
The finite impulse response (FIR) digital filter is a spatial domain filter with a frequency domain representation. The theory of the FIR filter is presented and techniques are described for...

Miller T, Sampathkumaran K
J Nucl Med
. 1982 Jan;
23(1):66-72.
PMID: 7054454
Digital filtering is a powerful mathematical technique in computer analysis of nuclear medicine studies. The basic concepts of object-domain and frequency-domain filtering are presented in simple, largely nonmathematical terms. Computational...

Radiology
. 1981 Jun;
139(3):719-23.
PMID: 7232740
Gated radionuclide imaging with 99mTc-labeled red blood cells was employed to assess changes in right atrial (RA) volume in 17 subjects. Studies were repeated within two hours in five of...
