Our optimal window setting was based on that in a previous report, which noted that the 100-kVp protocol for cardiac CT with a display preset of about 1.3 times window level and window width yields almost the same image contrast as that with the 120-kVp protocol.

In terms of radiography / radiology, kVp is the tube voltage / tube potential between the cathode and the anode, set by the operator. The unit eV (or keV as used in the range of general radiography, MeV as used by Radiation Therapy) describes the energy of the particles - in this case, the electrons in the x-ray tube, and the x-ray photons coming off the anode and towards the patient.

The hip, abdomen, and pelvis are even thicker and denser than the knee or shoulder. Additional kVp is required for adequate penetration. Settings in the 75-80 kVp range may be used. The portal venous phase image, acquired using 120-kVp in 2014 with a window width of 350 HU and a window level of 40 HU shows, appropriate brightness and contrast. B. The portal venous phase image, acquired using 80-kVp in 2015 with the same window setting as (A), is considered too bright for optimal visualization. C. The arterial phase image acquired using 80-kVp in 2015 with the same window setting as (A) CT liver window settings. Radiology 1999;210:60 1-604.

100 kVp Low-Tube Voltage Abdominal CT in Adults: Radiation Dose Reduction and Image Quality Comparison of 120 kVp Abdominal CT Hong Il Ha, MD, 1 Seong Sook Hong, MD, 2 Min-Jeong Kim, MD, 1 and Kwanseop Lee, MD 1: 1 Department of Radiology, Hallym University Medical Center, Hallym University Sacred Heart Hospital, Anyang, Korea.

A setting in the 65-75 kVp range is usually selected for these body structures. The hip, abdomen, and pelvis are even thicker and denser than the knee or shoulder. Additional kVp is required for adequate penetration. Settings in the 75-80 kVp range may be used.

28 Feb 2015 It is important that the kVp setting reflects what is actually coming out of the tube to ensure reproducibility. This lab was conducted in x-ray room 4 FFD (Focal Film Distance), The distance between the x-ray tube and the film. High kVp produces a long scale of contrast, which is necessary for soft tissue 14 Apr 2011 setting using anthropomorphic phantoms. • Application guidance of a Radiologist and/or Medical kVp values for film-screen imaging were. av R Bujila · 2020 — CT provides radiologists with unobstructed views of patient anatomy. Evaluating the impact of scan settings on automatic tube current With SUREkV, the lowest kV will be selected based on patient size and SUREExposure settings for low-kVp imaging.

The principles of technique chart formulation can be applied to any species and anatomic area. The method presented here applies to x-ray machines that have variable kVp and exposure time settings. A setting in the 65-75 kVp range is usually selected for these body structures. The hip, abdomen, and pelvis are even thicker and denser than the knee or shoulder.
