Lung cancer is the most critical reason for death. To enhance cancer detection the radiologists using distinctive scans and X-ray’s. Consequently, we use CT scan images for inspecting the interiors of the body. An automatic cancer detection system proposed to distinguish cancerous tumor from the CT scan images. The cancer detection scheme consists of four stages. They are preprocessing, segment...

Cone-beam CT (CBCT) images have recently become an established modality for treatment verification in radiotherapy. However, identification of soft-tissue structures and the calculation of dose distributions based on CBCT images is often obstructed by image artefacts and poor consistency of density calibration. A robust method for voxel-by-voxel enhancement of CBCT images using a priori knowled...

Integrated SPECT/CT scanners are gaining popularity as hybrid molecular imaging devices which can acquire SPECT and CT in a single exam. CT can be a low dose non-contrast enhanced scan for attenuation correction and anatomical localization, or a contrast enhanced diagnostic quality scan for additional anatomical characterization. We present a pictorial review highlighting the usefulness of this...

This paper presents methods and a clinical procedure for integrating B-mode ultrasound images tagged with position information with a planning computed tomography (CT) scan for radiotherapy. A workflow is described that allows the integration of these modalities into the clinic. A surface mapping approach provides a preregistration of the ultrasound image borders onto the patient's skin. Succes...

Objective(s): 99mTc-PSMA SPECT/CT is a cost effective alternative for 68Ga-PSMA PET/CT. The aim of this study was to directly compare these two techniques in patients with prostate cancer. Methods: 28 man with prostate cancer were studied using 99mTc-PSMA SPECT/CT and 68Ga-PSMA PET/CT in a shor...

With the massive outbreak of coronavirus (COVID-19) disease, demand for automatic and quick detection COVID-19 has become a crucial challenge scientists around world. Many researchers are working on finding an automated effective system detecting COVID-19. They have found that computed tomography (CT-scan) X-ray images infected patients can provide more accurate faster results. In this paper, i...

An older male with multiple medical comorbidities presented to the emergency room after 3 days of worsening right upper quadrant pain. The patient had an elevated white blood cell count and mildly elevated liver functions. Initial ultrasound was equivocal and further imaging with CT scan was obtained. The CT scan was read as suggestive of cholecystitis, however a hepatobiliary scintigraphy (HID...

A C-arm equipped with a flat detector CT (C-arm CT) has been developed, which provides images with high spatial resolution that could facilitate effective 3D information during interventional procedures. The cone beam reconstructive method was applied for reconstruction of images. Time of reconstruction of 3D images was approximately one minute after the scan. The axial thin-slice images, the r...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2012-006867 DESCRIPTION A young woman presented with three pulmonary nodules identified in the right lower lobe discovered on an outside CT scan of the abdomen which was performed to investigate right flank pain. The pain was ascribed to urinary tract infection and resolve...

Routine evaluation of axial MR images of the cervical spine with high-intensity CSF (long TR/TE spin-echo or gradient-echo images) revealed apparent narrowing of the cord's anteroposterior diameter when these images were compared with corresponding postmyelography CT scans. This discrepancy was believed to be due to the truncation artifact at the CSF-cord boundary. To examine the truncation eff...
