Statistical process control to monitor use of a web‐based autoplanning tool

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose To investigate the use of statistical process control (SPC) for quality assurance of an integrated web‐based autoplanning tool, Radiation Planning Assistant (RPA). Methods Automatically generated plans were downloaded and imported into two treatment planning systems (TPSs), RayStation and Eclipse, in which they were recalculated using ...

Design and Development of a Heart Rate Measuring Device using Fingertip [PDF]

Procs. of the IEEE International Conference on Computer and Communication Engineering (ICCCE10), pp. 197-201, Kuala Lumpur, Malaysia, May 11-13, (2010), 2013
In this paper, we presented the design and development of a new integrated device for measuring heart rate using fingertip to improve estimating the heart rate. As heart related diseases are increasing day by day, the need for an accurate and affordable heart rate measuring device or heart monitor is essential to ensure quality of health. However, most

Treatment planning with a 2.5 MV photon beam for radiation therapy

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose The shallow depth of maximum dose and higher dose fall‐off gradient of a 2.5 MV beam along the central axis that is available for imaging on linear accelerators is investigated for treatment of shallow tumors and sparing the organs at risk (OARs) beyond it.

MENTAL STATUS AND HEART RATE VARIABILITY [PDF]

, 2008
The results let us suppose that there are at least three periodical phenomena of HRV in frequency range related with mental status. Two of them have not been discovered and physiologically explained yet.

Does resting heart rate measured by the physician reflect the patient’s true resting heart rate? White-coat heart rate

Indian Heart Journal, 2018
Objectives: In cardiology, resting heart rate (HR) and blood pressure (BP) are key elements and are used to adapt treatment. However HR measured in consultation may not reflect true resting HR.

Correlation of heart rate recovery and heart rate variability with atrial fibrillation progression

Journal of International Medical Research, 2021
Objective To examine the combination of heart rate recovery (HRR) and heart rate variability (HRV) in predicting atrial fibrillation (AF) progression. Methods Data from patients with a first detected episode of AF who underwent treadmill exercise testing

Interaction between heart rate variability and heart rate in pediatric population.

Frontiers in Physiology, 2015
Background: Heart rate variability (HRV) is primarily heart rate (HR) dependent, and therefore, different HR may exert different impact on HRV. The objectives of the study were to evaluate the effect of HR on HRV in children and to determine whether HRV ...

Changes in heart rate and heart rate variability as a function of age in Thoroughbred horses. [PDF]

, 2017
We investigated changes in heart rate (HR) and HR variability as a function of age in newborn foals to old Thoroughbred horses. Experiments were performed on a total of 83 healthy and clinically normal Thoroughbred horses.
