An educational endeavor has been initiated to provide the diagnostic radiology (DR) community with an up-to-date resource describing the physics and clinical implementation of DR imaging physics. The resource will be widely, and freely, available to enhance t...

Implement a Four-Dimensional CT (4DCT) procedure using a QUASAR™ Respiratory Motion Platform and a custom sphere phantom to quantitatively evaluate the volumetric reconstruction accuracy and spatial location tracking precision of 4DCT acquisitions.

Understanding of medical physics is essential for safe and effective radiation oncology practice. This study evaluates current instructional practices for physics education in radiation oncology physician residency programs following the release of the AAPM/A...

Interesting case examples from pediatric imaging discussed by a radiologist.

HyperSight imaging (HS-CBCT) is commercially available for TrueBeam linear accelerators enabling an advanced iterative reconstruction algorithm with metal artifact reduction (iCBCT-MAR). iCBCT-MAR reduces scatter and improves image quality in the presence of...

To evaluate the imaging performance, Hounsfield Unit (HU) accuracy, and proton‑dose calculation implications of three newly released Varian ProBeam 360⁰ CBCT reconstruction algorithms—iCBCT, iCBCT Acuros, and iCBCT MAR Adaptive—compared with the standard filt...

Quantitative PET imaging biomarkers such as metabolic tumor volume (MTV) and maximum standardized uptake value (SUVmax) have demonstrated prognostic value in lymphoma; however, these metrics fail to characterize intratumor heterogeneity. This study aimed to a...

In order to initiate a quality control (QC) process for clinical photon-counting computed tomography (PCCT), this work evaluates the applicability of AAPM Task Group Report 299 (TG299) for multi-energy CT (MECT) systems to PCCT, highlighting gaps in and recom...

Grayscale ultrasound is widely used in breast screening, diagnosis, and ultrasound-guided biopsy, particularly for detecting breast lesions. However, current Quality Control (QC) methods provide limited and often subjective assessment of lesion detectability...

With the number of proton centers increasing, each facing intermittent downtime or need for renovations. Developing optimal approaches to maintain uninterrupted treatment is essential to preserve clinical outcomes. This study outlines key risk factors, workfl...

The modulation transfer function (MTF) is a standard metric for quantifying the spatial resolution of radiographic imaging detectors. Measurement of the MTF can be achieved through the Noise Response (NR) method, which utilizes only flat-field images for MTF...

To survey current clinical practice, assess priorities, and identify resource gaps related to environmental sustainability in medical imaging physics.

Brachytherapy with short-ranged diffusing alpha emitters offers a novel therapeutic modality to treat recurrent glioblastoma in previously irradiated areas. A neurosurgical navigation system traditionally used for biopsies is used to localize and implant the...

Although being over 20 years old, NCRP 147 is still the "gold-standard" with respect to shielding for diagnostic rooms. However, the standard is still over 20 years old and is outdated with some of today's technologies and modern systems. Therefore, although...

The increasing variety and rapid evolution of MR-conditional, active implanted medical devices (AIMDs) in the last decade has expanded the medical physicists’ scope of practice to include the provision of expert safety consultation on the presence of these de...

A multi-institution study is underway to characterize the organ doses received by adult patients undergoing ten common types of fluoroscopically guided interventional (FGI) procedures in the United States. Unlike diagnostic procedures, FGI are not standardize...

This session is dedicated to reviewing the aims and contents of recently or soon-to-be published Task Group Reports emerging from the Subcommittees under the Imaging Physics Committee, and will aim to answer questions on the contents of these Reports.

In this educational session, current techniques and future directions of breast MRI will be examined. The current landscape and expanding indications for breast MRI will be discussed. Technical aspects of contrast-enhanced and non-contrast techniques will be...

Diagnostic and Interventional Radiology Physics

Interventional CT procedures often involve multiple scans of the same anatomy, contributing substantially to patient dose. Because guidance tasks do not require diagnostic‑quality imaging, helical protocol parameters can be reduced to lower exposure, which is...

Direct imaging of Y‑90 bremsstrahlung with SPECT remains challenging because the continuous photon energy spectrum introduces scatter and septal penetration which reduces contrast and complicates quantitative reconstruction. Optimal energy‑window placement is...

MRI is increasingly integral across both diagnostic imaging and radiation therapy, yet quality assurance (QA) practices remain fragmented and often limited to phantom-based methods. While phantoms provide essential system checks, they cannot fully capture pat...

Photon-counting detector CT (PCD-CT) is one of the most significant advances in CT over the past decade. As PCD-CT enters routine practice, evidence of benefit across cardiothoracic, neuro, and oncologic applications continues to grow. Realizing its full valu...
