SUMMER COURSE IN MEDICAL PHYSICS 2024

IndoQCT and IndoseCT for CT Image Quality and Dosimetry Measurements

 

The Summer Course in Medical Physics 2024 is organized by the Department of Physics, Faculty of Sciences and Mathematics (FSM), Diponegoro University (UNDIP), Semarang, Central Java, Indonesia. The Summer Course is a seven-day online activity that will expose the participants to knowledge and skills in image quality measurements of computed tomography using IndoQCT and IndoseCT software. Moreover, its quality performance is also compared with dose measurements to ensure optimal future computed tomography (CT) scanning protocol. In brief, the summer course will cover various practical measurement skills as follows: computed tomography dose index volume (CTDIvol), size-specific dose estimate (SSDE), dosimetry for CT with tube current modulation (TCM) technique, CT number consistency, CT number uniformity and homogeneity, CT number linearity, noise image and noise power spectrum (NPS),  spatial resolution (visual observation, modulation transfer function (MTF), and task transfer function (TTF)), low-contrast detectability (LCD), slice thickness, CT alignment, gantry tilts, and advanced image quality on clinical patient images.

Title:

Impact of dispersive proton beam on reference dosimetry in a synchrotron spot scanning system

Dr Tan Hong Qi is currently a senior medical physicist in National Cancer Centre of Singapore (NCCS) and is also a clinical instructor in Duke-NUS medical School. He received his PhD from National University of Singapore and completed his residency in NCCS. He is active in both the radiotherapy research and education in Singapore for which he was recognized with institutional level awards and recent SEAFOMP young leader award. His current research interests are the application of AI in radiotherapy, adaptive radiotherapy, and proton therapy.

Abstract:

We have recently commissioned the largest proton therapy center in Singapore and have treated more than 30 patients over the last 4 months after the first clinical start date. This talk will share some of our commissioning experience with Hitachi ProBeat proton therapy which is a spot scanning synchrotron delivery system. In particular, we will report the observation of a large fluctuation in reference dosimetry measurement with a square field and an ion chamber measurement at the plateau region of a monoenergetic proton beam. An investigative journey reveal that the fluctuation originated from the dispersion in the proton beam. This accelerator physics term will be introduced, and we will show for the first time, the feasibility of measuring it in the clinic.

 

Title:

Automated dose and image quality measurements from clinical CT images for CT optimization

Dr. Choirul Anam completed his Ph.D at Physics Department, Bandung Institute of Technology (ITB).  He received Master degree from University of Indonesia (UI) and the B.Sc degree in physics from Diponegoro University (UNDIP). He is currently working as a Lecturer and Researcher at the UNDIP. His research interests are medical image processing and dosimetry for diagnostic radiology, particularly in CT. He has authored and co-authored over 200 papers. In the last ten years, he was the first author over 50 papers. One of his papers published in the Journal of Applied Clinical Medical Physics had been awarded as the Best Medical Imaging Physics Article in 2016. He received the Best Paper Award during 15th South East Asian Congress of Medical Physics (SEACOMP). He was also recognised as an Outstanding Reviewer for Physics in Medicine and Biology in 2018 and for Biomedical Physics and Engineering Express in 2019. He was also awarded as the SEAFOMP Young Leader Awards 2019 for his contribution in CT dosimetry and image quality from the South East Asian Federation of Organizations for Medical Physics (SEAFOMP). He is developer of two software, i.e. IndoseCT and IndoQCT (www.indosect.com).

 

Abstract:

Recent studies revealed that computed tomography (CT) scanning poses a potential cancer risk in patients. Although the risk is considered much smaller than the benefits of CT scanning to accurately diagnose patient abnormalities, the CT examination must be optimized. In radiation optimization, an image of sufficient quality to diagnose the patient must be achieved with the smallest possible dose. Up until now, image quality and radiation dose were usually evaluated using a standard phantom of standardized characteristic. The evaluation of image quality and radiation dose using the standard phantom is very good for assessing dependency on controllable variables, such as tube currents, tube voltage, pitch, reconstruction filter, and beam width. However, they are also influenced by uncontrollable variables, such as body size and body region. For optimization purposes, the controllable and uncontrollable variables must be considered simultaneously. This talk will discuss methods of automated image quality (noise and spatial resolution) and patient dose (i.e. size-specific dose estimate (SSDE)) directly from image of patient.
