Article
Full-text available
In the article we have proposed an application of several image processing algorithms to extract renal vessels. Earlier identification of the tumor feeding arteries facilitates conducting a zero-ischemia partial nephrectomy and preservation of renal function. This minimally invasive procedure is also beneficial for a patient. The study began with v...
Chapter
HTIG was initiated at AGH in the autumn/winter semester of 2021/2202. The project classes HTIG is a micro-scale experience of healthcare innovation generation where students learn dedicated tools and techniques the hard way (Learning by Doing, Problem-Based Learning, Design Thinking). To reinforce this educational experience useful tools to maintai...
Article
Minimal-invasive procedures come with significant advantages for the patient. They also come with problems as the navigation/guidance of the devices to a target location is either based on pre-operatively acquired images and then performed free-hand or is accompanied by intraoperative imaging such as MRI or CT that is expensive, complicated and pro...
Article
Full-text available
Three-dimensional (3D) printed model of the renal vasculature shows a high level of accuracy of subsequent divisions of both the arterial and the venous tree. However, minor artifacts appeared in the form of oval endings to the terminal branches of the vascular tree, contrary to the anticipated sharply pointed segments. Unfortunately, selective las...

Purpose Percutaneous needle insertion is one of the most common minimally invasive procedures. The clinician’s experience and medical imaging support are essential to the procedure’s safety. However, imaging comes with inaccuracies due to artifacts, and therefore sensor-based solutions were proposed to improve accuracy. However, sensors are usually...
Conference Paper
Fractal dimension can be applied to angiography, to evaluate the changes of renal vasculature caused by pathological processes. However, angiograms are 2D representations of 3D structures of varying orientation. In this work, we examined the impact of the spatial orientation of intrarenal vascular tree on the calculated fractal dimension.
Conference Paper
The minimally invasive approach for renal surgeries, among others, requires preoperative determination of intrarenal arteries. Their proper identification based on standard preoperative CT images is still not a fully solved problem. Therefore, we decided to resolve this issue by providing a tree topology model using post-mortem kidneys. The number...

With development of medical diagnostic and imaging techniques the sparing surgeries are facilitated. Renal cancer is one of examples. In order to minimize the amount of healthy kidney removed during the treatment procedure, it is essential to design a system that provides three-dimensional visualization prior to the surgery. The information about l...
Article
Full-text available
Minimally invasive procedures for the kidney tumour removal require a 3D visualization of topological relations between kidney, cancer, the pelvicalyceal system and the renal vascular tree. In this paper, a novel methodology of the pelvicalyceal system segmentation is presented. It consists of four following steps: ROI designation, automatic thresh...
Conference Paper
Full-text available
From the preoperative partial nephrectomy planning perspective, it is essential to expose separately different kidney structures and to analyze their mutual topological relations. Only then, the identification of possible conflicts prior to surgical intervention can be facilitated. To enable this, we propose a segmentation frameworks for renal vasc...
Conference Paper
Full-text available
In this article we have proposed several image processing techniques enabling the extraction of 3D tumor affected renal vascularity from CT scans in order to facilitate partial nephrectomy. The information which vessels supply the tumor is crucial to eliminate ischemic injury and allows the usage of the selective clamping method. However, until now...

With development of medical diagnostic and imaging techniques the sparing surgeries are facilitated. Renal cancer is one of examples. In order to minimize the amount of healthy kidney removed during the treatment procedure, it is essential to design a system that provides three-dimensional visualization prior to the surgery. The information about location of crucial structures (e.g. kidney, renal ureter and arteries) and their mutual spatial arrangement should be delivered to the operator. The introduction of such a system meets both the requirements and expectations of oncological surgeons.
