Ion radiotherapy is used to treat tumors located close to critical structures such as the brainstem, spinal cord, or optic nerves. In these cases, it is crucial to deliver an adequate dose to the tumour to halt its progression, while minimizing exposure to adjacent healthy tissues. Even minor variations in dose distributionโon the order of several millime-tersโcan have significant clinical...
Ion-beam therapy can offer advantages over the standard radiotherapy with photons, especially for cancer treatments where organs at risk are in close proximity to the tumor to be treated. These advantages mainly result from the characteristic of delivering highly focused doses to the tumor. However, this potential can sometimes not be fully used in clinics, since the focused dose distribution...
Carbon-ion radiotherapy provides superior precision in targeting tumors, while significantly reducing the exposure of surrounding healthy tissue to radiation dose as compared to conventional X-ray radiotherapy. However, the same underlying principle increases the sensitivity of the dose distribution to variations of patient positioning and anatomical changes such as nasal cavity filling or...
Introduction
Carbon-ion radiotherapy (CIRT) enables highly precise dose delivery through its highly localized dose deposition and enhanced biological effectiveness. However, current treatment guidelines generally do not include daily control imaging throughout the course of a multi-day therapy. As a result, anatomical changes that may occur between fractions cannot be considered due to the...
In current particle radiotherapy practice, it is necessary to evaluate and monitor the beam delivery for the purposes of quality assurance [1]. The current approach at PTC utilizes a scintillator detector (IBA Lynx PT) for determining the accuracy of beam delivery. This detector, while being heavy and large, requires individual dedicated measurements. Additionally, it has a restricted surface...
Introduction
Computed Tomography (CT) is an integral part of contemporary medicine. Conventional CT scanners are equipped with Energy Integrating Detectors (EID), which are based on indirect conversion of the incoming photons into electric signal for the image generation. EID-based CT shows limitations regarding tissue contrast and spatial resolution. A turning point of the actual CT...

Introduction
According to the World Health Organization (WHO), cancer remains one of the leading causes of death worldwide. Radiotherapy is often the primary or sole therapeutic approach used in treatment. Ensuring that each patient...
Photon-counting spectral detectors (PCD) have significantly advanced CT imaging by reducing image noise, enhancing contrast and spatial resolution, and enabling spectral imaging [1]. These benefits have extended to ยตCT imaging, where small-pixel (<100 ยตm) PCDs have allowed material-specific quantitative imaging at high spatial resolution [2]. Similarly, phase-contrast x-ray imaging (XPCI) has...
