Self-adaptive LED lighting time of collimator

Abstract: Conventionally, the collimator lighting time is a constant and non-revisable value.

This article proposes to adjust the LED lighting time of collimator according to individual

examinations or scans.

In x-ray imaging systems, a light source, such as LEDs, is provided to project a visible light beam

onto the subject to be imaged so as to indicate the area of exposure (also called the field of

radiation sometimes). Such a light source is often called collimator lighting.

Conventionally, the light source is switched on by clinicians and then switched off after the

elapse of a predetermined time period, and such predetermined time period is constant and

not revisable. The clinicians may switch on the light source by various ways, such as clicking a

button. X-ray imaging can be used for many different examinations, such as imaging different

parts of the body. For certain examination, it normally takes longer time for the clinicians to set

up the area of exposure and/or arrange the region of interesting inside the area of exposure,

and thus the clinician may need to switch on the light source several times before he/she

completes the setting. It is very inconvenience for clinicians and it waste more time.

This article proposes to adjust the pre-determined time period according to individual

examinations or scans. For example, different values are configured for the predetermined

time period according to different position/pa...
