Using time-domain integration (TDI) and a two-dimensional sensor for X-ray imaging of moving objects allows us to overcome the trade-off between SNR and position resolution. Applying on-chip instead off-chip TDI decreases several times required data throughput between an ASIC and the backend.

The NCs are classified into 0D quantum dots (QDs), 1D nanowires (NWs), and 2D nanoplatelets (NPLs) depending on their structures. Especially, 2D NPLs have the advantage of restricting quantum confinement effects only in the z-axis, unlike other NCs. Furthermore, NPLs composed of...

Backscatter X-ray imaging techniques are sensitive to organic materials (i.e., low-Z elements) due to a larger Compton scattering cross-section than that of other photon interactions. Therefore, it has the potential to be used as a security screening system to detect organic compounds, such as drugs and explosives. Additionally, it is possible to make a compact device because the X-ray...

As a demand for lithium-ion battery (LIB) cells in industry continues to grow, more accurate inspection techniques are required for ensuring quality assurance (QA) during production. Detecting defects accurately, such as metallic foreign matters and crack, is important for inline QA testing, where both fast-processing speed and high accuracy are essential. Particularly, in the post-packaging...

Radiography is one of the most commonly used diagnostic tools in veterinary practice and, particularly, denoising is one of the important image processing tasks. Robust noise removal will improve the image quality of diagnosis. There are many state-of-the-art noise reduction methods that have been studied in the image processing literature. Nevertheless, no algorithm that can robustly remove...

The irradiation study of silicon diodes was carried out in order to evaluate the effects of gamma-irradiation on p-type silicon. Three types of n-in-p diodes from different manufacturers were studied. The diodes had comparable active area and thickness but different initial resistivities and oxygen concentration. Thanks to that we were able to determine how different initial parameters...

Energy Dispersive X-ray Spectroscopy (EDS) is a common technique in electron microscopy to identify the chemical composition of samples. The standard method for analyzing the measurement data is semi-empirical, where the necessary correction factors have been determined decades ago using detectors much less sensitive than current ones.

Introduction. Structuring the x-ray beam into a 2D beamlet array, as shown in Fig. 1, enables three-modal x-ray micro-computed tomography (ฮผ-CT). The beamlets are created by placing an amplitude modulator (mask) with round apertures upstream of the sample [1,2]. Images with the following contrasts can be obtained: attenuation, refraction, and ultra small-angle scattering. Images with...

For the decommissioning of Fukushima Daiichi Nuclear Plants, a real-time dose-rate monitor under the high dose-rate situation is required to remove the debris remaining inside the plants. We have proposed a dose-rate monitor consisting of a scintillator, optical fiber, and CCD spectrometer. Since an over 100-m long optical fiber is used, some noises (โfiber noiseโ) such as scintillation...

Photon counting computed tomography (PC-CT) is a new type of CT that is being studied worldwide. The radiation dose produced by PC-CT can be reduced up to 1/100 of that produced by the currently available CT scanners. In addition, obtaining information from multiple energy bands makes it easier to acquire images without artifacts and leads to accurate material decomposition. In this study, we...

Dental panoramic imaging is a standard X-ray technique in dentistry that produces a single image of the facial structures, including both maxillary and mandibular arches and their supporting structures. A typical panoramic system consists of a slit-collimated X-ray tube, a linear-array type detector, and predetermined sequences for the panoramic scan motion and signal readout from the detector...

This study proposes a new signal multiplexing method for molecular imaging systems used in nuclear medicine, which can reduce the number of readout channels by utilizing charge reset amplifiers and a deep learning model. The results show that the proposed method can reduce 16 readout channels to one without distorting the original signal, using charge reset preamplifier and deep learning...

Photon-counting computed tomography (PC-CT) is a type of next-generation X-ray CT system for medical applications. It enables quantitative evaluation, such as concentration estimation, which is not possible with conventional CT systems. This is because the number and energy information of the individual incident X-rays can be obtained by reading them out in pulse form. By utilizing this...

Positron probes are widely used to accurately localize malignant tumors by directly detecting positrons emitted by positron-emitting radiopharmaceuticals that accumulate in malignant tumors. However, the conventional method of direct positron detection cannot distinguish some ฮณ-rays, resulting in misidentification of ฮณ-rays as positrons and increasing the error rate of positron detection. In...

A sandwich-like, double-layered detector can perform dual-energy imaging (DEI) at a single shot of x-ray exposure without object-motion artifacts. The energy separation between the measurements from two (front and rear) detector layers can be further adjusted by inserting an x-ray beam-attenuating material between them. However, the design of the interdetector filter highly impacts the dose...

The eye lens is one of the most radiation sensitive organs of the human body [1]. Therefore, the maximally allowed organ equivalent dose to the eye lens per year for occupationally exposed personnel has been reduced from 150 mSv/a to 20 mSv/a within a 5-year average with the dose not exceeding 50 mSv in any year [2]. Active eye lens dosimeters are of need in interventional radiology and...

The Passive Gamma Emission Tomography (PGET) device was approved by the IAEA for spent nuclear fuel safeguards inspections at the end of 2017. It is based on a collimator, consisting of a linear array of narrow slits with a pitch of 4 mm, with a relatively small CZT (cadmium-zinc-telluride) gamma ray detector behind each slit. Larger detectors would have a higher probability for detecting the...

Transmission X-ray security scanners are used to detect the smuggling of contraband articles, including weapons, narcotics, and explosives for homeland security. Current X-ray scanners use fixed tube voltages (i.e., 160 kVp); hence, it has a limitation in detecting thinly coated and/or low-density objects. To overcome this limitation, we are designing an X-ray scanner applying a variable tube...

The pile-up phenomenon can cause distortion in the recorded data and make it difficult to accurately measure the properties of individual radiation events. This issue can lead to an underestimation of the quantitative analysis, especially in radioisotope identification through gamma-ray spectroscopy. Recently, deep learning-based studies for pile-up correction have been conducted. Those...
