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.


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.



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).



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.


Pada tahun 2023, Dr. Choirul Anam terpilih untuk mendapatkan perhargaan The IUPAP Early Career Scientist Prize in Medical Physics 2022 dari International Organization for Medical Physics (IOMP) bekerja sama dengan International Union of Pure and Applied Physics (IUPAP).

Penerima penghargaan ini adalah ilmuan muda yang diangap paling memberikan kontribusi bagi fisika medis di dunia dan telah melakukan penelitian fisika medis dalam waktu maksimal 8 (delapan) tahun setelah lulus dari program doktor. Informasi lebih detil tentang penghargaan ini dapat dilihat pada laman: https://iupap.org/awards/young-scientist-prizes/. Penerima penghargaan ini hanya satu orang di dunia untuk setiap tahun. Penerima penghargaan dipilih oleh panitia khusus yang terdiri dari para ilmuan terkemuka di dunia.

Dr. Anam terpilih untuk menerima penghargaan ini untuk tahun 2022 ini. Penghargaan ini akan diberikan pada acara International Conference on Medical Physics (ICMP) yang akan diadakan pada 6-9 Desember 2023 di Mumbai, India. Sebelumnya, para ilmuan penerima penghargaan ini adalah: Dr. Ali Asghar Mowlai (2006, Iran), Dr. Leif Schröder (2009, Germany), Dr. Magdalena Stoeva (2012, Bulgaria), Dr. Ferdinand Schweser (2013, Germany), Dr. Jan-Bernd Hövener (2014, Germany), Dr. Guerda Massillon-JL (2015, Mexico), Dr. Francis Hasford (2016, Ghana), Dr. Abdul Nashirudeen Mumuni (2017, Ghana), Dr Kuo Men (2018, China), Dr Mitsuhiro Nakamura (2019, Japan), Dr Jaydev K Dave (2020, USA), dan Dr Chai Hong Yeong (2021, Malaysia) (https://www.iomp.org/recipients-iupap-young-scientist-award-in-medical-physics/).

Perlu diketahui bahwa Dr. Anam telah melakukan riset secara komprehensif tentang dosis radiasi dan kualitas citra dari pesawat computed tomography (CT). Dia bersama tim telah mengembangkan dua software untuk dosimetri CT (yaitu IndoseCT) dan untuk image quality pada CT (IndoQCT). Kedua software tersebut dapat diunduh dari laman: www.indosect.com. Hingga saat ini, kedua software telah didownload oleh mahasiswa, ilmuan, dan peneliti dari sekitar 50 negara.

Hingga saat ini, Dr. Anam telah mempublikasi sekitar 200 paper. Sekitar 50 diantaranya, Dr. Anam menjadi penulis pertama dan hampir 100 diantaranya terindeks di Scopus. Salah satu paper yang ditulis oleh Dr. Anam dan tim juga pernah diberi penghargaan oleh Asosiasi Fisikawan Medik Amerika (AAPM) sebagai Best Paper untuk Medical Imaging Physics. Dr. Anam juga telah mendapatkan penghargaan dua kali sebagai Outstanding Reviewer dari IOP Publishing. Pada tahun 2019, Dr. Anam juga mendapat penghargaan Young Leader Awards dari Asosiasi Fisikawan Medik Asia Tenggara (SEAFOMP). Pada tahun 2023 ini, Dr. Anam juga mendapat penghargaan sebagai Trusted Reviewer dari IOP Publishing.
