The present disclosure provides a radiation detection system, a radiation output device, and a radiation detection device. The radiation detection system includes a radiation output device having a radiation generation unit and an output control unit that controls output of radiation, and a radiation detection device having a radiographic image detector that detects radiation output from the radiation output device, and a recognition unit that recognizes whether radiation has been output from the radiation output device on the basis of a radiation detection signal output from the radiographic image detector. The output control unit causes radiation with a preset waveform pattern to be output from a time point of the start of outputting of the radiation, and the recognition unit recognizes the waveform pattern, thereby recognizing the start of outputting of the radiation.

The instant disclosure is directed to wearable dermatological systems with battery-free sensors. A wearable system may comprise a wireless, battery-free sensor configured to detect one or more characteristic features of a wearer's skin and communicate information relating to the one or more characteristic features of the wearer's skin to a reader. The reader may be coupled to the wireless, battery-free sensor. The reader may also be configured to collect the information related to the detected one or more characteristic features of the wearer's skin. The wearable system may be configured to measure the hydration level of a user's skin. A kit may also comprise the wearable system and one or more products.

The present disclosure provides a radiation detection system, a radiation output device, and a radiation detection device. The radiation detection system includes a radiation output device having an output control unit, and a radiation detection device having a recognition unit that recognizes whether radiation has been output from the radiation output device on the basis of a radiation detection signal. The output control unit causes radiation to be output at a first intensity from a time point of the start of outputting of radiation, and then causes the radiation to be output at a second intensity. The first intensity is an intensity higher than the second intensity and satisfying a threshold value condition set in advance in the recognition unit. The recognition unit recognizes that a detection signal of the radiation with the first intensity satisfies the threshold value condition, thereby recognizing the start of outputting of the radiation.

An apparatus and method are provided to correct for time-walk errors during photon detections (e.g., detecting gamma rays). A time-walk correction is determined using measurements of energy (or charge) that apply different time windows, enabling corrections accounting for variations in the ratio between fast and slow components in the detected pulse. For example, one time window can be used to integrate the leading end of the pulse, thereby predominantly measuring the fast component, while a second window is used to integrate a trailing end of the pulse to predominantly measure the slow component. Alternatively or additionally, low-pass and high-pass filters may select the slow and fast components, respectively. The time-walk correction is a function of multiple measurements representing different components (e.g., fast and slow) of the pulse shape.
