Summer Course in Medical Physics 2025

IndoQCT for CT Image Quality Measurements

The Summer Course in Medical Physics 2025 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 computed tomography image quality measurements using IndoQCT software. In brief, the summer course will cover various practical measurement skills as follows: 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.

About  IndoQCT

IndoQCT is software that automatically measures CT image quality. IndoQCT can measure many CT quality parameters (either manually or automatically), including CT number (accuracy, uniformity, homogeneity, and linearity), image noise (tolerance, uniformity, and NPS), spatial resolution (visual, MTF based on point, MTF based on edge, and TTF), slice thickness, low-contrast resolution (visual, contrast-to noiseration (CNR), LCD Error! Hyperlink reference not valid. statistical calculations), CT alignment, gantry tilt, distance accuracy, and distance between slice accuracy. IndoQCT can measure CT quality parameters from several types of phantoms available in the market, such as AAPM CT performance phantom, ACR CT accreditation phantom, CatPhan phantom, and phantoms supplied by CT vendors (GE, Siemens, Philips, and Toshiba). Moreover, several CT quality parameters can be measured directly from patient clinical images, such as CT number, image noise, LCD, spatial resolution, and alignment.

With IndoQCT, various image quality parameters can be set and detected manually or automatically using computational phantoms. This is particularly useful for providing a direct overview to students. Several filters for noise suppression are equipped in IndoQCT, such as adaptive mean filter (AMF), selective mean filter (SMF), bilateral filter (BF), non-local mean (NLM) filter, and others. Moreover, additional features are also included, such as resizing images, rotating images, and shifting images. An interesting feature not available in any other software is that multi-window blending can be performed in IndoseCT so that 2 or 3 windows can be displayed in one image in the form of color (red-green-blue). 

Programs

The summer course will be held Online from August 12 – 20, 2025, using the Zoom meeting application. Fourteen topics will be presented by speakers from Diponegoro University and its International University Partners. On each day, two sessions, 100 minutes each, are scheduled. The full agenda of the course is listed in the information below:
