The Essential Physics of Medical Imaging - Halaman 261
This requires the use of a sensitometer and a densitometer. A sensitometer is a device that emulates a range of incident radiation exposures by using a constant light source and calibrated optical attenuation steps to expose a mammographic ...

Restoration of Motion Picture Film - Halaman 115
Both types of sensitometer require lamps that have been calibrated to give a known intensity of light at a known voltage, usually less than the rated voltage of the lamp to give increased life. The lamps are run from a constant power source with ...

Design Considerations for a General Purpose Sensitometer
"A Kodak model 101 sensitometer has been improved from the original design and is now able to follow A.N.S.I, standards for exposure of almost all sensitized products.

Essentials of Radiologic Science - Halaman 105
The sensitometer and densitometer are utilized in radiology department quality assurance programs. Various equipment is necessary to perform sensitometry procedures. A penetrometer or sensitometer is required to produce a uniform range ...

Quality Management Review - Halaman 163
29. c Whether a sensitometer is set for single- or double- sided exposure is determined by the type of film being used for sensitometry. If mammography film is used, it is a singe-emulsion film and, therefore, the sensitometer should be set for ...

Radiographic Photography and Imaging Processes - Halaman 285
Appendix 2 The Sensitometer Another of the range of RMI instruments for image quality control in X-ray departments is the sensitometer. This is robust and measures 6 cm X 17.5 cm × 13.5 cm. It has a slot at one end into which a film may be ...

Physics for Diagnostic Radiology, Third Edition - Halaman 108
The whole process can be controlled by the preparation, at regular intervals, of test film strips obtained using a suitable sensitometer. This sensitometer consists of a graded set of filters of known optical density (figure 4.24) which is placed over ...

Mammographic Imaging: A Practical Guide - Halaman 289
The procedure is simple, and requires two separate pieces of equipment: the sensitometer and the densitometer. The sensitometer, used in the darkroom, exposes film with a gray scale of gradually increasing densities simulating a step ...

Progress in Medical Radiation Physics - Jilid 2 - Halaman 184
Another method of sensitometry that is widely used for quality assurance in processing conditions in radiology employs a simulated-light sensitometer. With this device, light intensity is adjusted by means of a neutral density filter through which ...
